  257 5. Compilation instructions
  258 
  259 First you must download wxWidgets. Audacity 2.1.2 requires wxWidgets 3.0.x, 
  260 preferably 3.0.2, which can be obtained from:
  261 
  262    http://www.wxWidgets.org/ .
  263 
  264 The libsndfile library is also required and is included in Audacity obtained 
  265 from GitHub. 
  266  
  267 CMake ( http://www.cmake.org/ ) is required to build the local copy of 
  268 the libsoxr resampling library used by Audacity, unless you install 
  269 libsoxr-dev and use that system library.
  270 
  271 Installation of other libraries is optional, see:
  272    http://wiki.audacityteam.org/wiki/Developing_On_Linux#optional . 
  273 
  274 If you install libraries using a package management system like Apt or RPM,
  275 you need to install the "dev" (development) packages for each library.
  276 
  277 To compile on Linux, Mac OS X and other Unix systems, execute these 
  278 commands:
  279 
  280   ./configure
  281   make
  282   make install  # as root
  283 
  284 To see compile-time options you can set, you can type
  285   ./configure --help
  286 
  287 If you want to do any development, you might want to generate a configure cache
  288 and header dependencies:
  289 
  290   ./configure -C
  291   make dep
  292 
  293 To compile on Windows using MSVC++, please follow the instructions in
  294 win\compile.txt in the source code. 
  295 
  296 To compile using Xcode on Mac OS X, see the instructions in mac/compile.txt.
  297 
  298 For more information on compilation, please visit:

  328    * Built in Generators were not usable in Chains.
  329    * Plot Spectrum could not change values without losing focus.
  330    * Track dropdown menu settings could affect other tracks.

  336    * LADSPA and LV2 generate plug-ins failed when white space selected.
  337 
  338  * Mac OS X
  339    * Confusing behaviour importing / exporting AU presets. In particular, 
  340      Apple Audio Units silently applied an imported preset.

  343 
  344  * Effects:
  345    * Built in effects now support presets.

  371 Changes in version 2.1.0: 
  372 
  373 Bug fixes:
  374 
  375  * Interface:
  376    * Typing "j" or "k" in a label track activated the "move cursor" shortcut.
  377    * Spectrogram log (f) view displayed incorrectly until vertically zoomed.
  378    * Fixed crash after zooming out on vertical scale beyond +/-1.0. 
  379    * Selections made with Selection Toolbar were not restored after Undo.
  380    * Undo could fail silently if a selection included/touched a clip boundary.
  381 
  382  * Imports and Exports 
  383    * If there were invalid FFmpeg libs in system PATH this prevented Audacity
  384       recognising the installed FFmpeg or the FFmpeg specified in audacity.cfg.
  385 
  386  * Mac OS X:
  387    * Fix uninitialized buffer - this should correct playback buzz or crackle
  388       where the upper of multiple tracks started with or contained white space.   
  389    * Device names were corrupted when using system language other than English. 
  390    * Fixed crashes using (external program). 
  391    * Waves v9 Audio Units should now work correctly.
  392 
  393  * GNU/Linux:

  397    * Fix silent failure exporting FFmpeg, MP2 or OGG to an unwritable folder.
  398    * Fix ENTER activated an effect when OK button was greyed out.  
  399 
  400  * Operating system and sound device support:
  401    * (Windows) Audacity 2.1.0 requires Windows XP SP3 (32-bit) or XP SP2
  402       (64-bit), Vista, Windows 7, Windows 8 or 8.1. 
  403    * (Windows) Audacity is now compiled using Visual Studio 2013.  
  404    * (Windows) Recording with WASAPI host now includes experimental support 
  405       for physical inputs (up to 24-bit depth) as well as loopback recording.  
  406    * (OS X) 10.10 (Yosemite) is now supported including Apple Audio Units.
  407    * Please report any issues with WASAPI recording/playback or Yosemite 
  408       to http://audacity.sourceforge.net/contact/#feedback .
  409    * (Linux Ubuntu) Under Unity, keyboard shortcuts are not visible in the
  410      Audacity menus. Keyboard shortcuts are visible if you install the classic
  411      GNOME Flashback interface or under Unity if you open Audacity with the
  412      UBUNTU_MENUPROXY=0 environment variable. Audacity compiled from source
  413      will ship with src/audacity.desktop.in set to UBUNTU_MENUPROXY=0 but it
  414      will remain up to distributions to use this desktop file.    
  415    
  416 Changes and Improvements:
  417 
  418  * Effects:
  419    * LADSPA, VST and Audio Unit (OS X) effects now support real-time preview, 
  420       save/load of user presets and saving effect settings across sessions. 
  421       Note: Real-time preview does not yet support latency compensation.
  422    * VST effects now support import/export of FXB preset banks. 
  423    * Shell VST effects that host multiple plugins are now supported.
  424    * All Effect Menu items (built-in or plugin) can now be used in a Chain. 
  425    * Items in the Effect, Generate or Analyze Menus can be sorted or grouped
  426       by name, publisher or class of effect.   
  427    * Noise Removal is improved and renamed to "Noise Reduction".  
  428    * Change Speed has new time controls for current and new length. You can 
  429       now enter the speed change as a multiplier e.g. "2" is twice as fast.  
  430    * New "Crossfade Tracks" effect can be used for crossfading two tracks. 
  431       This replaces Cross Fade In and Cross Fade Out.  	
  432    * Nyquist Prompt and most shipped Nyquist effects now have Preview button. 
  433 
  434  * Interface:  
  435    * Redesigned Meter Toolbars: The default shows separate Record and Playback   
  436       Meters, half-height so they can be wider while docked, in gradient style. 
  437    * A frequency selection can now be made (and spectral edit effects applied
  438       to those frequencies) when in a spectrogram view. You can also create
  439       or adjust frequency selections in a new "Spectral Selection Toolbar"
  440       (available at View > Toolbars).  
  441    * Transcription Toolbar (Play-at-speed) can now loop play and cut-preview. 
  442    * Timer Record now saves recordings automatically into an existing project.  
  443    * New Armenian translation. 
  444

  447 Bug fixes for:
  448 
  449  * Interface:
  450    * Region Restore did not restore the region after using Preferences. 
  451    * Dragging selections with the keyboard or Selection Toolbar digits 
  452       was very slow.  
  453    * (Windows) Help > About Audacity crashed when run in Magyar language.  
  454    * (OS X) Some full and reduced Menu Bar items were not translated.  
  455    * (OS X and Linux) Fixed various interface crashes.
  456 
  457  * Effects:
  458    * Reverb and Paulstretch were missing from Chains.
  459    * Analyze > Contrast could report very inaccurate rms levels.
  460    * Noise Removal: Attack and decay times were half as long as set.  
  461    * (OS X and Linux) Nyquist effects ran much more slowly than on Windows. 
  462 
  463  * Click or drag on the Timeline after Loop Play continued to loop.
  464  * Transcription Toolbar did not play slower than 0.1x speed.
  465  * (Linux) Audacity did not build if python 2 was not available.  
  466  * Projects did not reopen correctly if they contained tracks having 
  467    2^31 samples or greater of audio (just over 13.5 hours at 44100 Hz).
  468 
  469 
  470 Changes and Improvements:
  471 
  472  * Interface:
  473    * Redesigned, searchable Keyboard Preferences with Tree, Name and Key views.  
  474    * Edit Menu: "Cut" and "Delete" are now in the top level of the menu.  
  475    * Transport Menu now includes "Play/Stop" and "Play/Stop and Set Cursor" 
  476       (use Keyboard Preferences to create shortcuts for "Play" and "Stop").
  477    * Tracks Menu now includes "Mix and Render to New Track". 
  478    * Track Drop-Down Menu now has Move Track To Top and Move Track To Bottom. 
  479    * New right-click menu choice "Delete Label" to remove single labels.
  480    * "Snap To" now offers choice of snap to the "closest" or "prior" position.
  481       Note: the previous "Snap To On" keyboard shortcut will no longer work.   
  482    * "Snap To" settings are now independent for each project.
  483 
  484  * Effects:
  485    * Truncate Silence: redesigned with simpler option "Truncate Detected 
  486       Silence" to shorten to the specified length without compressing silence.
  487    * VST effects: New "Settings" dialog lets you specify buffer size (for 
  488       faster processing) and enable buffer delay compensation (to prevent
  489       inserted silence). Compensation may cause a crash in a few plug-ins. 
  490    * VST effects now support standard FXP presets.  
  491    * LV2 effects are now supported on all platforms (textual interface only).    
  492 
  493  * Import or export using FFmpeg now requires FFmpeg 1.2 or later (or libav
  494     0.8 or later). For recommended downloads of recent FFmpeg please visit:
  495     http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#ffdown .
  496  * New Tamil translation (largely complete). 
  497  * (Windows) FLAC exports can now exceed 2 GB in size. 
  498  * (OS X) Easier Audacity installation using the DMG: drag the Audacity folder
  499     to the /Applications shortcut. 
  500  * (OS X) Audacity 2.0.6 will not officially support OS X 10.10 Yosemite when 
  501     released (in particular, Apple Audio Units may not open in Audacity).
  502  * (Linux) Self-compiled builds of Audacity now search for system LADSPA 
  503     effects in /usr/lib/ladspa.  
  504 
  505 
  506 Changes in version 2.0.5:
  507 
  508 Bug fixes for:
  509 
  510  * Shaped dither was corrupted and too loud on all stereo exports except FLAC. 
  511 
  512  * Keyboard Preferences: some Edit and Align commands for different sub-menus
  513     showed the same name.   
  514 
  515  * Recordings stopped with "Stop and Set Cursor" shortcut could not be undone.
  516 
  517  * In locales that use comma for decimal separator:
  518     * Text boxes with slider in Nyquist effects only produced whole numbers 
  519        when using comma to enter a fractional number. Text boxes without 
  520        slider still have this problem.   
  521     * Built-in generators produced silence after running a Nyquist effect.  
  522 
  523  * (Windows) When first changing to Windows WASAPI host, the input volume slider
  524     in Mixer Toolbar was enabled when it should have been permanently disabled. 
  525 
  526  * (Windows) On some machines, launching Audacity then recording from the current
  527     Device Toolbar input would not record until the input was reselected. 
  528 
  529  * (OS X) Frequent crashes occurred on importing audio files on some machines.
  530 
  531  * (OS X) Files did not open using Finder "Open with", double-clicking the 
  532     file or dragging the file to the Audacity icon.    
  533 
  534  * (Linux 64-bit) Fixed a crash when using Equalization.
  535 
  536  * (Linux) It was not possible to open an effect or other dialog then navigate
  537     through the dialog using TAB.
  538 
  539  * (Linux) The Play shortcut did not play a read-directly WAV, AIFF or FLAC 
  540     import if the warning for importing uncompressed files appeared. 
  541 
  542 
  543 Changes and Improvements:
  544 
  545  * Tracks Menu:
  546    * The separate commands that aligned track start or end with the cursor or
  547       with selection start are combined into "Cursor/Selection Start" commands.
  548    * "Align and Move Cursor" renamed to "Move Selection when Aligning".   
  549 
  550  * Label Tracks:
  551    * Labels Editor now allows empty labels to be saved on closing the editor.
  552    * TAB and SHIFT+TAB when the label track has focus now always move forwards
  553       or backwards respectively to the nearest label.
  554 
  555  * (Windows) On a very few machines, the Windows WDM-KS low latency audio host
  556     introduced in Audacity 2.0.4 caused Audacity to hang or the computer to 
  557     crash. WDM-KS has been removed from 2.0.5 until it can be safely enabled.
  558 
  559  * (Windows and OS X) Screen reader improvements for Install VST Effects dialog.  
  560 
  561  * (OS X) Audio Unit plug-ins detected by Audacity on launch are now not loaded
  562     until chosen from the Effect menu. This should speed up launch and avoid
  563     crashes at launch due to misbehaving Audio Units.  
  564 
  565  * (Linux) Update to PortAudio r1910 fixes memory and other bugs under ALSA.
  566 
  567  * (Linux) Applied fix for wxGTK 2.8.12 bug which resulted in loss of Audacity's
  568     menu bar (or visual corruption under Unity) on Debian-based systems.
  569 
  570 
  571 Changes in version 2.0.4:
  572 
  573 Bug fixes for:
  574 
  575  * Keyboard Preferences: Shortcuts for Generators, Effects and Analyzers 
  576     were not exported. All imported shortcut changes were discarded.
  577  * Equalization curves were corrupted in Graphic EQ mode after switching 
  578     to/from Draw Curves or after	running the effect then reopening it. 
  579  * Change Pitch displayed corrupted values when reducing pitch or editing 
  580     "from" Frequency. Detection was very inaccurate at high sample rates. 
  581  * Bass Boost no longer clips if the track contains 32-bit audio.   
  582  * Auto Duck was excessively slow on older machines. 
  583  * (Windows) Exported MP3 comments tags were not seen by Windows programs.   
  584  * (Windows and OS X) Audacity crashed if you used system quit before
  585     file import was complete. 
  586  * (Linux) Equalization crashed Audacity if the XML file was corrupted.  
  587  * (Linux) When configuring effect parameters in "Edit Chains", "Preview" 
  588     (not intended to be functional) caused a crash.
  589  * (Linux) LICENSE.txt and README.txt were wrongly installed in
  590      /usr/local/share/doc instead of /usr/local/share/doc/audacity/ .
  591  * Accessibility: ENTER did not toggle selectedness of a label track unless
  592     a label was selected.  
  593  * Numerous other interface fixes.  
  594 
  595 
  596 Changes and Improvements:
  597 
  598  * New "Reverb" effect to replace GVerb, based on the original "Freeverb".
  599  * New View > Go to Selection Start and Go to Selection End commands.  
  600  * New "Align End to End" command to append existing tracks to each other. 
  601  * Change Tempo now supports fractional BPM.    
  602  * Plot Spectrum now supports FFT sizes up to 65536.  
  603  * WAV files now support "Album Title", "Track Number" and "Genre" LIST INFO 
  604     tags and also support ID3 tags.
  605  * Handle a bug in older iPods or some OS X applications that cause them to 
  606     refuse AIFF files whose metadata contains an uneven number of characters,   
  607  * (Windows) Added support for "Windows WDM-KS" host which can provide very
  608     low latencies if you reduce "Audio to Buffer" in Recording Preferences.
  609  * (Windows Vista and later) You can now record computer playback by choosing
  610     the new "Windows WASAPI" host in Device Toolbar then a "loopback" input.
  611  * (Windows and Mac OS X): VST scanning dialog now replaced with a dialog
  612     for choosing which VST effects to load. 
  613  * (Linux) CTRL + ALT can now be used to smooth samples in Draw Tool. 
  614  * Modules Preferences replaced with a dialog on launch of Audacity 
  615     enabling you to choose which modules to load.  
  616 
  617 
  618 Changes in version 2.0.3:
  619 
  620 Bug fixes for:
  621 
  622  * Crash using Undo whilst time-shifting a track.
  623  * Crash using Repair if the selection extended into an empty track.
  624  * Export Multiple didn't prevent export if there was no audio or 
  625     all audio was muted. This allowed export of small invalid files. 
  626 
  627  * Time Track:
  628    * Loop Play of a speeded-up track inserted silence.
  629    * Playback and rendering was significantly inaccurate, creating 
  630       audible and visual glitches. 
  631 
  632  * Accessibility:
  633    * The mnemonics character "&" was read out by screen readers in 
  634       most of the Preferences choices.
  635    * NVDA did not read static text in most dialogs. Text can now be
  636       read by using INSERT + B.
  637    * JAWS and Window-eyes misread the "Duration" control in Silence 
  638       Generator. 
  639    * Toolbar buttons could not be pressed by ENTER 	
  640 
  641  * Other interface bug fixes.
  642 
  643 
  644 Changes and Improvements:
  645 
  646  * The SoX Resampler library (libsoxr) has replaced libresample in 
  647     Audacity releases, offering both higher quality and greater speed. . 
  648 
  649  * Time Tracks new features:
  650    * "Set Range" now changes only the range of the Time Track,
  651       preserving the pitch/speed set by any existing warp points.
  652    * Vertical scale added with options for linear and logarithmic  
  653       display and interpolation.
  654    * Upper and lower speed limits will now be remembered when saving 
  655       and reopening a project in 2.0.3. Warp points in projects saved 
  656       by previous Audacity versions will be correctly restored in 2.0.3.
  657    * Warp points saved in a 2.0.3 project will be preserved if opened
  658       in previous versions but playback and display will be incorrect.
  659 
  660  * New effects: 
  661    * Studio Fade Out (uses a filtered "S" curve).
  662    * Adjustable Fade (accessible effect for creating partial fades 
  663       and adjustable fade shapes).   
  664    * Bass and Treble (replaces Bass Boost).  
  665  
  666  * Real sample rates up to 384000 Hz are now supported for playback 
  667     and recording in high resolution devices (the maximum is up to 
  668     192000 Hz for Windows DirectSound host).
  669  
  670  * Labeled Regions in Edit Menu is renamed to "Labeled Audio" and now 
  671     allows splits to be placed at point labels. Labeled audio regions
  672     that touch without overlapping are treated as separate regions. 
  673     Overlapping labeled audio regions are treated as a single region.
  674 
  675  * Compilation: cmake is required in order to build libsoxr.
  676 
  677  * New Croatian translation of Audacity.
  678 
  679 
  680 Changes in version 2.0.2: 
  681 
  682 Bug fixes for:
  683 
  684  * Interface:
  685    * "Retain labels" Interface Preference did not retain labels for
  686       a region that snapped exactly to both label edges.
  687    * Projects did not save the track selected state.
  688    * (OS X, Linux) Timer Record: Interlinking of the Start, End and 
  689       Duration controls was broken.
  690    * (Windows) JAWS screen-reader did not read the "Draw curves" and 
  691       "Graphic EQ" radio buttons in Equalization correctly.  
  692 
  693  * Envelopes and Clips: 
  694    * Exporting (or any render operation) on a track containing 
  695       split lines could create clicks at the split lines. 
  696    * Dragging a clip into another track caused a crash if Sync-Lock
  697       Tracks was enabled and there was also a label track. 
  698 
  699  * Effects and Analysis:
  700    * Normalize could crash if the track name contained "%". 
  701 
  702 
  703 Changes and Improvements:
  704 
  705  * Duration controls when generating at a point now default to 
  706     hh:mm:ss + milliseconds format. Selection Toolbar also defaults
  707     to that format on first installation or resetting preferences. 
  708  * Toolbars visual improvements:
  709    * "Snap To" in Selection Toolbar now has an explanatory tooltip.  
  710    * Device Toolbar tooltips now display the selected device. 
  711    * Increased default width of Device Toolbar and Meter Toolbar.   
  712  * Improvements and some bug fixes to Nyquist effects, including:
  713    * Delay (new option to prevent duration change)
  714    * Sample Data Export (new "L-R on Same Line" layout option)
  715    * Risset Drum (new "Amplitude" slider). 
  716  * Importing a labels file writes the file name to the name of the 
  717     Label Track, and exporting a labels file offers the name of the
  718     last Label Track in the project.
  719  * Removed the "Audio cache" option from Directories Preferences 
  720     due to frequent crash reports. All data operations will now 
  721     be written to disk and not to RAM. 
  722  * Removed the FFmpeg "On-Demand" option from Libraries Preferences
  723     (this fixes Audacity not building if configured --without-ffmpeg). 
  724  * Compilation: Progress on making the Modules feature mainstream. 
  725     Modules can now be individually enabled and disabled in Preferences.
  726 
  727 
  728 Changes in version 2.0.1: 
  729 
  730 Bug fixes for:
  731 
  732  * Interface:
  733    * Selection Toolbar: a value for the previous whole second 
  734       displayed if the value was close to a whole second. 
  735    * Finding zero crossings could cause the selection to expand into
  736       white space at either side of the clip. 
  737    * Clips did not drag to another track if mouse was over a selection.
  738    * Mixer Board: Rendering four tracks resulted in a redundant Track
  739       Strip followed by a crash. 
  740 
  741  * Imports, Exports and Files:
  742    * Exporting to WAV or AIFF led to a "Libsndfile says" error or
  743       corrupted output due to order of metadata in imported files. 
  744    * (Mac) Fixed crashes importing MP3 files on PPC machines.    
  745    * (Linux Ubuntu) .Aup files could not be associated with Audacity
  746       (they opened in the web browser instead).
  747 
  748  * Effects and Analysis:
  749    * Normalize: Fixed issues where normalization could be to wrong
  750       value if applied with DC offset correction, or if applied to 
  751       "read-directly" WAV and AIFF files before On-Demand completed. 
  752    * Sliding Time Scale: fixed an audible discontinuity at the 
  753       beginning of the processed selection; fixed a serious quality
  754       problem on Linux 64-bit. 
  755  
  756  * Other miscellaneous bug fixes, including fix to prevent zooming
  757     with mouse wheel or ball scrolling the content off-screen. 
  758 
  759 
  760 Changes and Improvements:
  761 
  762  * Shortcuts can now be added in Keyboard Preferences to items in the
  763     Generate, Effect or Analyze menus, including user-added plug-ins.   
  764 
  765  * Nyquist Effect plug-ins can now be added to Chains. 
  766 
  767  * New "Paulstretch" effect for extreme slowdown without pitch change. 
  768 
  769  * New "Sample Data Export" Analyze effect for exporting a file 
  770     containing amplitude values for each sample in the selection. 
  771 
  772  * New Preference (off by default) to import files On-Demand (without 
  773     seek ability) when using the optional FFmpeg library. 
  774 
  775  * New Preference (off by default) to retain labels when deleting a
  776     selection that snaps to the label without extending past it.
  777 
  778  * (Windows installer) New option to reset Preferences on next launch. 
  779 
  780  * (Mac) Audacity now has excellent compatibility with the VoiceOver
  781      screen reader. For details, please see:
  782      http://manual.audacityteam.org/help/manual/man/accessibility.html#mac .  
  783 
  784  * CleanSpeech Mode (no longer supported) will not now be enabled 
  785     even if it was enabled by an earlier version of Audacity.  
  786 
  787  * Added Serbian (Latin and Cyrillic) translations.   
  788 
  789 
  790 Changes between version 1.3.14 Beta and 2.0.0:
  791 
  792 Bug fixes for:
  793 
  794  * Interface:
  795    * Fixed playback speed and synchronization problems when dragging  
  796       clips or tracks between tracks having different sample rates.
  797    * (Windows) Removed a crash risk where shortcuts could be
  798       used to record or import in one project while importing or 
  799       exporting in another.    
  800 
  801  * Imports and Exports:
  802    * Fixed crashes when changing the sample format of read-directly WAV
  803       or AIFF files using the Track Drop-Down Menu. 
  804    * Fixed a crash importing MP3 files that had duplicate metadata tags 
  805       (this is a bug in current libsndfile which has been patched in 
  806        Audacity; MP3 files mislabeled as WAV which have duplicate tags
  807        will still crash Audacity on Linux if Audacity has been compiled 
  808        against an affected version of system libsndfile).
  809    * Fixed an issue where excessively high or corrupted sample values in
  810       the audio could corrupt exports from the start of the problem for
  811       the rest of the file, and could corrupt the rest of the project.  
  812    * (Linux) Fixed Audacity could not be compiled against FFmpeg
  813       0.7.x and 0.8.x. 
  814 
  815  * Effects and Analysis:
  816    * Fixed crash on launch when using "Ambisonic Decoders (PC)" VST  
  817       plug-ins and other plug-ins that enable additional floating point
  818       exceptions. 
  819    * Fixed Plot Spectrum background could be transparent on some machines. 
  820    * Bug fixes for Click Track, High Pass, Low Pass and Vocal Remover.  
  821    * Chirp, Tone and Silence generators now remember their settings.
  822  
  823  * Other miscellaneous bug fixes.  
  824 
  825 
  826 Changes and Improvements:
  827 
  828  * New Interface preference to show the track name in the display (this
  829     is off by default). 
  830  * Longer default Playback preference for effects preview and preview 
  831     before cut. 
  832  * Restored use of Page Up and Page Down to scroll horizontally.  
  833 
  834

  845       characters in their name. 
  846    * (Linux) Playing existing tracks while recording in mono could cause
  847       recordings to be distorted or low-pitched. 
  848 
  849  * New features: There are dozens of new features in 2.0.0, including: 
  850

  869 Changes in version 1.3.14 Beta: 
  870 
  871 Bug fixes for:
  872 
  873  * Interface:
  874    * Excessive delay occurred when typing into labels in long projects. 
  875    * Last digit of TimeText controls could not be manipulated in some formats.
  876    * (Windows, OS X) Play and Record shortcuts did not work after clicking in
  877       Device Toolbar. 
  878    * (OS X, Linux) Crash occurred if Toolbars were reset during playback or
  879       recording. 
  880 
  881  * Imports and Exports:
  882    * MP2 files were not importable without FFmpeg library or an import rule. 
  883    * Files that could only be imported using FFmpeg imported as noise with
  884       no error message if FFmpeg was not available. 
  885    * Files containing PCM audio but an incorrect extension (such as MP3) 
  886       caused a freeze. 
  887 
  888  * Effects and Analysis:
  889    * An empty command could be added to a Chain which then displayed a 
  890       Nyquist error message when run.  
  891    * Plot Spectrum didn't preserve signal level if multiple tracks were 
  892       analyzed.  
  893 
  894  * Other bug fixes:
  895    * Audacity has been provisionally fixed so that it can no longer create 
  896       block files longer than the sample format or project format allows, 
  897       and can no longer delete these, which led to data loss. Any overlong 
  898       blocks found are preserved but "orphaned", so will appear as silence.
  899    * Orphan block files were wrongly reported if cutting or copying to 
  900       the clipboard then reopening the project in the same session. 
  901    * Fixed some crashes and incorrect movement of audio when dragging tracks.
  902    * (Windows) Data loss is now prevented when encountering a corrupted
  903       .aup file created in ANSI builds. 
  904    * (Linux) Restore building if USE_PORTMIXER is not defined. 
  905  
  906 Changes and Improvements:
  907 
  908  * Normalize: Faster processing and improved interface. Left-right balance 
  909     in unsplit stereo tracks is now preserved by default, with a checkbox 
  910     option provided to process stereo channels independently.   
  911  * Spectrograms now allow window sizes up to 32768 and frequencies up to
  912     half the sample rate (the maximum possible).
  913  * Mix and Render now preserves clip length by not rendering white space 
  914     between time zero and first audio, and preserves audio before time zero.
  915     To retain silence before the audio starts, generate silence after render.     
  916  * Grouped some Edit Menu items into "Remove Audio" and "Clip Boundaries".  
  917  * CleanSpeech Mode removed from Interface Preferences (it still runs if it
  918     was enabled in a previous Audacity but can only be turned off there). 
  919  * (OS X) Added support for AudioUnit MusicEffects (but no MIDI support). 
  920  * (Linux) Set the per-user files directory per the program name set in 
  921     configure.
  922  * (Linux) Changed the default location of the Audacity temporary directory
  923     to be in /var/tmp not /tmp, so preserving the directory between reboots. 
  924 
  925 
  926 Changes in version 1.3.13 Beta: 
  927 
  928 Bug fixes for:
  929 
  930  * Interface:
  931    * Cutting or copying from a track at a given sample rate into a track
  932       at another rate resulted in speed-changed audio. 
  933    * Generating inside a clip could modify the clip length or create 
  934       spurious clips.
  935    * Recorded stereo tracks were only half the height of imported or 
  936       generated stereo tracks. Imported stereo files had a "1" appended 
  937       to the track name.  
  938    * Edit > Region Save did not save the cursor position.  
  939    * (Windows) Projects crashed when clicking rapidly inside the interface
  940       or when applying repeated effects towards the end of audio tracks. 
  941    * (Windows) Some Unicode characters could not be typed into labels,
  942       or caused a freeze using some input methods.
  943    * (OS X) Crash when quitting an empty project window, or when closing the
  944       main project window while a progress dialog was on screen.
  945    * Numerous other interface fixes including Dependencies dialog, 
  946       Keyboard Preferences and spurious lines drawn on waveform.
  947 
  948  * Imports and Exports:
  949    * Support added for later versions of the optional FFmpeg library up to 
  950       current FFmpeg HEAD. This should significantly improve FFmpeg support
  951       on Linux. FFmpeg downloads for Windows and Mac updated to v0.6. This
  952       fixes mono AAC files importing as stereo, though current 0.5 versions
  953       of FFmpeg will still work.
  954    * Both FFmpeg and LAME should now be properly detected even when other 
  955       versions of those libraries exist on the system. 
  956    * New warning (on by default) for importing uncompressed audio files. 
  957       Better error messages when read-directly uncompressed files are missing. 
  958    * Imported ID3v2 metadata tags were removed when exporting without the 
  959       Metadata Editor appearing (for example, when using an export command
  960       in Chains). Note: As a result of this fix, ID3v1 tags must now be 
  961       written by exporting using (external program) and an installed LAME. 
  962    * U-Law/A-Law files with WAV headers now use the standard 18 byte fmt chunk,
  963       so should now be recognised by most telephony applications.   
  964    * Variable bit rate MP3s exported using "MP3 Files" were larger than 
  965       necessary because using the bit reservoir was disabled.   
  966    * (OS X) Files imported from iTunes could create invalid characters in the
  967       .aup project file, causing an error when re-opening the project. Note: 
  968       An error "reference to invalid character number" will still occur if 
  969       re-opening a project created in previous Betas that contains such 
  970       characters. To fix the issue, open a back-up copy of the .aup file in a
  971       text editor, turn off word wrap, then in the line indicated in the error
  972       message, remove the string of characters that starts with &# and ends
  973       with a semi-colon (;).
  974 
  975  * Other bug fixes:
  976    * Nyquist effects: fixes for crashes, incorrect slider behaviour and better
  977       support for backslashes, double quotes and Unicode characters. 
  978    * (Windows and OS X) Processing of VST effects was substantially slower than
  979       in previous versions of Audacity.
  980    * (OS X 10.5 PPC) A first-time installation of Audacity Beta would hang
  981       on launch if VST effects were detected. 
  982    * (Linux) Recordings made with the pulse device crashed or stalled when
  983       using overdub and/or software playthrough.  
  984    * (Linux) Play-at-Speed crashed at 0.08 speed or lower if Audacity was
  985       configured with libsamplerate. 
  986  
  987 Changes and Improvements:
  988 
  989  * Control Toolbar renamed to Transport Toolbar.  
  990  * Device Toolbar (on by default) now contains all input and output device 
  991     choices, including host and recording channels. Input/output choices are 
  992     no longer in Mixer Toolbar on Windows XP or some older operating systems.
  993     New Transport > Rescan Audio Devices menu item to refresh the device list.  
  994  * New "Sync-Lock Tracks" feature (turned on in the Tracks menu) to allow
  995     groups of audio and/or label tracks to retain synchronisation when the
  996     track length changes. 
  997  * Equalization: New "Manage Curves" dialog for importing and exporting curves.
  998  * Noise Removal: New "Sensitivity" slider to adjust the noise threshold, and
  999     new option to isolate noise.
 1000  * New "Extended Import" Preferences for specifying different importers to
 1001     open specific file extensions.
 1002  * Improved Automatic Crash Recovery with all project changes autosaved. 
 1003  * MIDI tracks can be vertically zoomed, time shifted and display bar lines.
 1004     Note: the channel selection buttons are not available in 1.3.13.    
 1005  * (Windows and Linux) The window Close button and other system close or
 1006     shutdown commands now quit on closing the last window. File > Close now 
 1007     always clears to a new, empty project. 
 1008  * (OS X) Simpler installer with top-level "Audacity" folder. 
 1009 
 1010 
 1011 Changes in version 1.3.12 Beta: 
 1012

 1015  * Imports and Exports:
 1016    * AAC files could not be exported at 48000 Hz 
 1017    * When importing multiple native file formats using FFmpeg, all 
 1018       files after the first reverted to using the native importer
 1019    * FFmpeg custom export window too large on 800 x 600 resolution 
 1020       monitors 
 1021    * Projects froze if files imported via On-Demand were no longer 
 1022       available
 1023    * (Linux) WAV/AIFF exports were corrupted if overwriting an aliased 
 1024       file which had been imported using the command line
 1025 
 1026  * Labels:
 1027    * Cutting or deleting a region in the waveform and label track did 
 1028       not move the labels in advance of the cut 
 1029    * Incorrect behavior snapping to labels and boundaries when Snep To 
 1030       was enabled
 1031    * Labels can now be reversed if included with the audio selection 
 1032 
 1033  * Other bug fixes:
 1034    * When using non-English languages, Generate effects truncated the 
 1035       selected region
 1036    * Mice with high-precision scroll-wheels could cause a crash   
 1037    * Changing recording preferences using the Transport menu did
 1038       not update the menu in other open projects  
 1039    * (Windows 7) Clicking in a file open or save dialog caused files or 
 1040       folders to disappear from the list, and file filtering was broken
 1041 
 1042 Changes and improvements:
 1043 
 1044  * A hover tooltip is now provided if the Mixer Toolbar input selector 
 1045     cannot control the system slider for the selected input. 
 1046  * More intuitive behavior when moving and resizing labels by dragging 
 1047  * Support added for importing lists of files (LOF) containing relative 
 1048     paths

 1050     label or track names; "Success" dialog now resizable 
 1051  * New Equalization preset "Inverse RIAA", with new button to invert  
 1052     other curves
 1053  * Timer Record now remembers last scheduled duration 
 1054  * Meter Toolbar can now be made much narrower, and so more suitable for
 1055     vertical orientation  
 1056  * New Preferences choice for "System" language which is used on first 
 1057     run instead of asking user to choose language    
 1058  * Warning now provided if WAV/AIFF exports are not successfully
 1059     completed   
 1060  * (Linux) Improved icon set in compliance with freedesktop.org

 1068  * Imports and Exports:
 1069    * Bug when exporting partial selections caused too much audio to be 
 1070       exported is fixed.
 1071    * Fix corrupt files exported through FFmpeg when metadata included,
 1072       (metadata is now exported correctly in M4A files)
 1073    * Prevent saving a new Audacity Project over an existing one as this 
 1074       could corrupt both projects.
 1075    * Improved help for files that cannot be imported because the relevant
 1076       optional library is missing.
 1077 
 1078  * Effects:
 1079    * Allow effects which change the length of the audio they work on to also be
 1080       applied to selected label tracks, thus keeping them synchronized.
 1081    * Fixed inability in Nyquist plug-ins to add labels to an existing label track 
 1082    * (Mac) Equalization window was corrupted after Preview  
 1083    * (Linux 64-bit) Fixed crash Generating Click Track
 1084 
 1085  * Audio Devices:

 1088       resampling.
 1089    * Fix crash when opening Preferences on a machine where there are no
 1090       available audio devices.
 1091    * Fixes for bugs using Timer Record and Sound Activated Recording 
 1092 
 1093  * User Interface:
 1094    * Sizes of some dialogs adjusted to ensure they fit on the screen.
 1095    * Fix for supposedly "hidden" items appearing on screen with large
 1096       monitors.

 1112 
 1113 Bug fixes for:
 1114 
 1115  * Imports and Exports:
 1116     * Freeze importing audio files when Default View Mode set to 
 1117        Pitch (EAC)
 1118     * Simultaneous On-Demand imports sorted incorrectly

 1120        copy in the data at 24-bit quality
 1121     * WMA exports corrupted if they contained metadata 
 1122     * Metadata Editor appeared before the Export window when 
 1123        exporting to any format
 1124 
 1125  * Effects:
 1126     * Crash or hang using Equalization on longer tracks
 1127     * Reverse did not reverse clip boundaries

 1167 
 1168 
 1169 Changes in version 1.3.9 Beta:
 1170 
 1171 Bug fixes for:
 1172            * Crash, slow launch or excessive CPU/memory use arising 
 1173               from automatic VST support:

 1180            * Default View Mode now works
 1181            * Chains now always apply their stored parameters rather than 
 1182               those last used in Effect menu  
 1183            * Non-MP3 files imported via drag or Recent Files caused
 1184               crash if filter in file open window set to MP3
 1185            * AAC exports (using the optional FFmpeg library) were 
 1186               silenced 
 1187            * Generating audio always fitted the project in the window; 
 1188               fit now done only if generating in new track  
 1189            * View menu items/shortcuts incorrectly disabled when playing
 1190               or recording 
 1191            * DTMF generator defaulted to zero duration on open
 1192            * Unwanted interactions between linked audio and label tracks

 1246 Bug fixes for:
 1247               * Export Multiple: failed with no export or warning if empty 
 1248                  label encountered; silenced project and exported files if
 1249                  overwriting imported WAV files without copying the data in   
 1250               * Metadata Editor hidden if it was on a now unavailable second

 1700 
 1701 Changes in 1.3.0:
 1702 
 1703    New features
 1704    The new features in Audacity 1.3 have been grouped into the
 1705    following six major categories.
 1706 
 1707    1. Collapse/Expand Tracks
 1708       In Audacity 1.3, every track has an upward-pointing triangle at
 1709       the bottom of the label area on the left side of the track.
 1710 
 1711    2. Multiple clips per track
 1712       In Audacity 1.2, there is one audio 'clip' per track. There is
 1713       no easy way to time-shift part of a track without moving the
 1714       rest. In Audacity 1.3, you can split a single track into multiple
 1715       clips. You can move these clips around between different tracks,
 1716       making it easy to construct complex compositions out of hundreds
 1717       of smaller audio samples.
 1718 
 1719    3. Selection Bar
 1720       In Audacity 1.2, the current selection is contained in a
 1721       status bar at the bottom of the window. In Audacity 1.3,
 1722       this is replaced by a fully functional Selection Bar, which
 1723       displays and controls the current selection (your choice of
 1724       Start and End, or Start and Length), and the current audio
 1725       position. The selection bar is fully editable - just click
 1726       in any field and type to change the current selection precisely.
 1727       In addition, many formatting options allow you to view times in
 1728       different units, such as samples, CD frames, or NTSC video frames.
 1729 
 1730    4. Improved Label Tracks
 1731       Label Tracks are Audacity's way for you to create markings 3
 1732       and annotations within your project. In Audacity 1.3, Label
 1733       Tracks are much improved, with support for overlapping labels,
 1734       and support for modifying both the left and right edge of the
 1735       label region just by clicking and dragging.
 1736 
 1737    5. QuickTime and Audio Units on Mac OS X
 1738       On Mac OS X, Audacity can now import and audio file supported
 1739       by Apple's QuickTime technology. This includes .MOV and .MP4
 1740       (AAC) files. Unfortunately encrypted audio files (such as
 1741       those from the iTunes Music Store) cannot be imported directly
 1742       into Audacity - Apple does not allow this to be done easily
 1743       because it would be too easy to circumvent the encryption this way.
 1744 
 1745       Also on Mac OS X, Audacity now supports Audio Unit plug-ins.
 1746       Audacity searches for Audio Units in the usual location, in the
 1747       system or user's Library folder.
 1748 
 1749    6. Other features
 1750       Better performance with large projects
 1751 
 1752       Project integrity check on open
 1753 
 1754       Transcription toolbar
 1755 
 1756       Upload
 1757 
 1758       Batch
 1759 
 1760       Cut lines
 1761 
 1762       CleanSpeech
 1763 
 1764 
 1765 Changes in 1.2.4:
 1766 
 1767   * The File menu now includes a list of recent files.
 1768 
 1769   * The "Generate Silence" effect now prompts for a length.
 1770 
 1771   * Audacity is now built with Vorbis 1.1, which features better encoding
 1772     quality and file compression.
 1773 
 1774   * Dragging sound files into the Audacity window now works on Mac OS X
 1775     and Linux, as well as Windows.  (Before, it worked only on Windows.)
 1776 
 1777   * The "View History" window can now discard old undo levels to save disk
 1778     space on Windows.  (This previously worked only on Linux and Mac.)
 1779 
 1780   * "Preferences" command is now in Edit menu.
 1781 
 1782   * "Plot Spectrum" command is now in Analyze menu.
 1783 
 1784   * Opening a project file saved by a later version of Audacity displays
 1785     an intelligent error message.  Also, trying to import a project file
 1786     (instead of open it) displays an intelligent error message.
 1787 
 1788   * Audacity now compiles in Visual C++ .NET 2003.
 1789 
 1790   * Other minor bug fixes.
 1791 
 1792   * New or updated translations: Arabic (ar), Czech (cs), Finnish (fi),
 1793     Hungarian (hu), Japanese (ja), Norwegian (nb), Slovenian (sl),
 1794     Simplified Chinese (zh_CN), Traditional Chinese (zh_TW).
 1795 
 1796 
 1797 Changes in 1.2.3:
 1798 
 1799   * Fixed a bug that caused recording to stop or display incorrectly
 1800     after about 50 minutes on some Windows systems.  (This was partly
 1801     fixed in Audacity 1.2.2, but still didn't work on some systems.)
 1802 
 1803   * The Change Pitch and Change Tempo effects have been upgraded to
 1804     use a new version of the SoundTouch library by Olli Parviainen,
 1805     with better speed and higher quality.
 1806 
 1807   * libsndfile has been upgraded to version 1.0.11.
 1808 
 1809   * Fixed a bug that caused the program to run slowly when using the
 1810     Envelope tool.
 1811 
 1812   * Shift-clicking on a mute or solo button now un-mutes (or un-solos)
 1813     all other tracks.
 1814 
 1815   * Nyquist plug-ins can now accept strings as input.  Also, a "Debug"
 1816     button has been added to Nyquist effect dialogs, which allows you
 1817     to see all of the output produced by Nyquist, for aid in debugging.
 1818 
 1819   * When the audio file referenced ("aliased") by an Audacity project is
 1820     missing, Audacity will now always play silence.  Before, Audacity
 1821     would sometimes repeat the most recent audio that was played previously.
 1822 
 1823   * VU Meters will now always reset when audio I/O has stopped.
 1824 
 1825   * Fixed a major Mac-only bug that was causing Audacity to crash at seemingly
 1826     random times, but especially during audio playback and recording.
 1827 
 1828   * New or updated translations: Italian (it), Hungarian (hu),
 1829     Ukrainian (uk), Spanish (es). Polish (pl), Simplified Chinese (zh),
 1830     Norsk-Bokmal (nb), French (fr).
 1831 
 1832 
 1833 Changes in 1.2.2:
 1834 
 1835   * VU Meters added for both playback and recording.  Click on
 1836     the recording meter to monitor the input without recording.
 1837 
 1838   * Export Multiple - new feature that lets you export multiple
 1839     files at once, either by track, or split based on labels.
 1840 
 1841   * Attempt to automatically correct latency in full-duplex recordings.
 1842     (This does not work perfectly, and is not yet supported on all
 1843     systems.  It will improve in future versions.)
 1844 
 1845   * Fixed a serious bug that could cause data loss when you save and
 1846     then reload and re-edit an Audacity project containing repeated
 1847     or duplicate data.
 1848 
 1849   * MP3 tags dialog will only pop up the first time you export as
 1850     MP3; after that it will not pop up again as long as you have
 1851     filled in at least one tag.
 1852 
 1853   * You can now add a label at the current playback position - in
 1854     the Project menu, with a shortcut of Ctrl+M.
 1855 
 1856   * Clicking on a label now selects all of the tracks, making it
 1857     easier to use the label track to recall selections.
 1858 
 1859   * Windows: Fixed a crash in the Time Track "Set Rate" command.
 1860 
 1861   * Fixed a bug that caused problems with recordings over 45 minutes
 1862     on some Windows systems.
 1863 
 1864   * Mac OS X: Improved support for the Griffin iMic by fixing a bug
 1865     that was causing it to always record in mono instead of stereo.
 1866 
 1867   * Added support for Software Playthrough (listen to what you're
 1868     recording while recording it, or while monitoring using a VU
 1869     meter) - this makes it possible, for example, to record using one
 1870     audio device while listening to it play through a separate device.
 1871 
 1872   * Unix/Linux: Fixed freeze caused by captured mouse when audio
 1873     device hangs.  (Audacity may not respond, but it will no longer
 1874     freeze all of X.)
 1875 
 1876   * Fixed a cosmetic bug that caused improper waveform display if
 1877     you tried to open an Audacity project saved on a different
 1878     platform (e.g., copying a project from a Mac to a PC).
 1879 
 1880   * Fixed bug that could cause instability when pasting, splitting,
 1881     or duplicating a label track.
 1882 
 1883   * You can now change the font of a label track by choosing "Font..."
 1884     from the label track's pop-up menu.
 1885 
 1886   * Basic printing support has been added.  Currently it scales the
 1887     entire project to fit exactly on one page.  Try printing in
 1888     landscape orientation for best results.
 1889 
 1890   * Mac OS X and Windows: Audacity ships with a newer version (1.0.1)
 1891     of the Ogg Vorbis encoder.  Vorbis compression will now have higher
 1892     quality and smaller file sizes.
 1893 
 1894   * Fix a bug that occasionally caused crashes when applying effects
 1895     to split tracks.
 1896 
 1897   * Zoom In / Zoom Out now properly disable when they're not available.
 1898 
 1899   * Fixed disk memory leak in Preview
 1900 
 1901   * Other minor bug fixes and performance improvements.
 1902 
 1903 
 1904 Changes in 1.2.1:
 1905 
 1906   * The following translations have been added or updated:  Finnish,
 1907     French, Hungarian, Italian, Japanese, Norwegian, Polish, Russian.
 1908 
 1909   * Fix a bug that could cause data to be lost when pasting audio
 1910     from one project into another, after the first project has been
 1911     saved and closed.
 1912 
 1913   * Fix a possible crash when opening or resizing the Equalization
 1914     window, especially when using large system fonts.
 1915 
 1916   * Don't allow percentages less than -100% in Change Pitch/Speed/Tempo
 1917     effects (fixes a possible crash).
 1918 
 1919   * Fix a crash when the temporary directory is not available on startup.
 1920 
 1921   * Correctly load ID3 tags saved in Audacity project files.
 1922 
 1923   * On Linux and OS X, store lockfiles in the temp directory instead of
 1924     the user's home directory.  This fixes problems in lab environments
 1925     where users have restricted or network-mounted home directories.
 1926 
 1927   * Fix a bug that prevented Nyquist effects from running when certain
 1928     regional settings were activated.
 1929 
 1930   * Fix a bug in the Quick Mix command that could cause old temporary
 1931     files to not be deleted.
 1932 
 1933   * Linux: Fix endianness problems in playback on PowerPC.
 1934 
 1935   * Linux: Fix compilation problem in Nyquist on MIPS.
 1936 
 1937   * Linux: Include a more recent PortAudio v19 snapshot (fixes compilation
 1938     problems when building with the --with-portaudio=v19 option).
 1939 
 1940   * Two new Nyquist plug-ins: "Cross Fade In" and "Cross Fade Out."
 1941 
 1942   * Other minor bug-fixes.
 1943 
 1944 
 1945 Changes in 1.2.0:
 1946 
 1947   * New cross-fade effects.
 1948 
 1949   * Fix problem where samples were drawn in the wrong position
 1950     when zoomed all the way in.  This caused the drawing tool
 1951     to move a different sample than the one under the cursor.
 1952 
 1953   * Don't use id3v2.4 tags, which are not yet supported by
 1954     most players.  (This was fixed in 1.2.0-pre2, but appeared
 1955     again by accident in 1.2.0-pre3.)
 1956 
 1957   * Correctly display translated messages in the status bar.
 1958 
 1959   * When the cursor is on-screen, the Zoom In button now zooms
 1960     to the area around the cursor.
 1961 
 1962   * Mac OS X: Fixed audio problems on the Apple PowerMac G5.
 1963 
 1964   * Linux/ALSA: Work around a bug in ALSA's OSS emulation that
 1965     caused Audacity's playback cursor to move too quickly.
 1966 
 1967   * Microsoft Windows: The Audacity source code should now
 1968     compile out of the box on Windows.
 1969 
 1970   * Many new/updated translations.
 1971 
 1972 
 1973 Changes in 1.2.0-pre4:
 1974 
 1975   * Fixed problems that could occur when importing certain
 1976     non-seekable PCM audio files, such as GSM610.
 1977 
 1978   * Fixed bug that was causing the samples to shift off-screen
 1979     horizontally when zoomed in very far and the track had a
 1980     time-shift offset.
 1981 
 1982   * Fixed bugs in the new resampler that added noise to resampled
 1983     audio on some systems. If you experienced noise when exporting
 1984     to a WAV, MP3 or OGG file you may have been bitten by this bug.
 1985 
 1986   * Fixed bug that led to occasional crashes when using the
 1987     time-shift tool in conjunction with high zoom factors.
 1988 
 1989   * Dithering is now only applied on export when it is really
 1990     necessary (e.g. when converting float samples to 16-bit).
 1991 
 1992   * Files that only contain mono tracks are now automatically
 1993     exported to stereo files when they contain tracks which are
 1994     panned to the left or the right.
 1995 
 1996   * The Delete key can now be used to delete the current selection,
 1997     in addition to the Backspace key.
 1998 
 1999   * Fixed bug where Audacity didn't ask whether to save
 2000     changes if you close the project or exit while recording.
 2001 
 2002   * Mac OS X: Supports Playthrough (listen to what you're recording
 2003     while recording it) if your hardware device supports it.
 2004 
 2005   * Mac OS X: Audacity is now a package (you can right-click on
 2006     Audacity.app and select 'Show Package Contents').  Launch time
 2007     has improved significantly.
 2008 
 2009   * MS Windows: Fixed problem that caused Windows XP to use
 2010     the short name of a file ("TESTFI~1.AUP"), which led to
 2011     problems when the file was later opened again using the
 2012     long file name.
 2013 
 2014   * MS Windows: Fixed bug that caused file exports to fail
 2015     if the destination directory was the root folder of a
 2016     Windows drive.
 2017 
 2018   * MS Windows: Audacity's application information which
 2019     is written to the Windows registry now always contains
 2020     the full path to the executable.
 2021 
 2022   * MS Windows: Fixed problems in trying to set the Windows
 2023     registry as non-admin user, for file-type associations.
 2024 
 2025   * Make sure the "Save" command is enabled after changing
 2026     gain and pan sliders.
 2027 
 2028   * Updated translations.  Added translator credits to the
 2029     "About" window in localized versions.
 2030 
 2031 
 2032 Changes in 1.2.0-pre3:
 2033 
 2034   * Fixed bug where Export is grayed out when nothing is
 2035     selected.
 2036 
 2037   * Fixed crash caused by opening Audacity on a computer with
 2038     a high-end sound card with no mixer support.
 2039 
 2040   * Fixed crash in Import Raw.
 2041 
 2042   * Fixed New Stereo Track.
 2043 
 2044   * Cosmetic fixes for Mac OS X.
 2045 
 2046   * Support for the VST Enabler on Windows added.
 2047 
 2048   * Fixed crash if you close Audacity while the Preferences
 2049     dialog is open.
 2050 
 2051   * Fixed duplicate-character bug in Mac OS X Label Tracks.
 2052 
 2053   * The recording level control on Linux now adjusts the IGAIN,
 2054     rather than the playthrough level of the recording source.
 2055 
 2056   * Fixed bug that caused corruption to 16-bit stereo recordings.
 2057 
 2058   * Fixed bug that caused data loss if you deleted all tracks in
 2059     a saved project and then open a new file into the same window.
 2060 
 2061   * Added support for alternate audio button order (in Interface
 2062     preferences)
 2063 
 2064   * Added preliminary support for wxX11
 2065 
 2066   * Added fully transparent Windows XP icon
 2067 
 2068   * Fixed crash if you try to record (or play) and no audio
 2069     devices exist, or if the audio device doesn't support the
 2070     mode you selected.
 2071 
 2072   * Audacity no longer sets the process priority to high while
 2073     recording on Windows.  Users can still do this manually
 2074     using the Task Manager.
 2075 
 2076   * Fixed bug that caused last ~100 ms of the selection to get
 2077     cut off on Windows.
 2078 
 2079   * Fixed FFT Filter and Equalization effects dialogs.
 2080 
 2081   * Fixed bugs in Unix build system (DESTDIR in locale directory,
 2082     choosing libsamplerate instead of libresample)
 2083 
 2084   * Support for LADSPA plug-ins on Windows added, and
 2085     three open source LADSPA plug-ins ported to Windows
 2086     (GVerb reverb, SC4 compressor, and Hard Limiter)
 2087 
 2088 
 2089 Changes in 1.2.0-pre2:
 2090 
 2091   * Online help completed.  The full manual is nearly complete
 2092     and will be posted to the web site for online browsing shortly.
 2093 
 2094   * Audacity will no longer let you do unsafe editing operations
 2095     while playing or recording.  This eliminates many potential
 2096     crashes.
 2097 
 2098   * Fixed ability to cancel Quit button.
 2099 
 2100   * New resampling library, with no restrictions on the maximum or
 2101     minimum rate of resampling.
 2102 
 2103   * Audacity now supports LADSPA plug-ins on all platforms, and
 2104     supports VST plug-ins through an optional LADSPA plug-in
 2105     called the "VST Enabler", which you can download separately.
 2106     Because of licensing issues, Audacity cannot be distributed
 2107     with VST support built-in.
 2108 
 2109   * Mac OS X keyboard shortcut problems have been fixed.
 2110 
 2111   * Mac OS X audio muting problems have been fixed.
 2112 
 2113   * Mac OS X playback/recording cursor sync problems have been fixed.
 2114 
 2115   * Silence now displays a straight line again, instead of nothing.
 2116 
 2117   * Added a vertical ruler to the Waveform dB display.
 2118 
 2119   * Fixed crash in Change Pitch.
 2120 
 2121   * You can now Paste if nothing is selected.
 2122 
 2123   * Canceling an Import operation doesn't cause an extra error
 2124     dialog to appear.
 2125 
 2126   * Audacity now handles filenames with international characters
 2127     correctly.
 2128 
 2129   * Now outputs ID3v2.3 tags (instead of ID3v2.4), to be
 2130     compatible with more MP3 players.
 2131 
 2132   * Minor improvements to build system on Unix systems.
 2133 
 2134 
 2135 New features in Audacity 1.2:
 2136   * User Interface
 2137     - Vertical zooming of tracks.
 2138     - Improved look and placement of toolbars.
 2139     - New custom mouse cursors.
 2140     - Complete implementation of editable keyboard shortcuts.
 2141     - Find zero-crossings.
 2142     - Mouse wheel can be used to zoom in and out.
 2143     - Multi-Tool mode.
 2144     - Amplify using envelope.
 2145     - Labels can store selections (like Audacity 1.0.0).
 2146 
 2147   * Effects

 2190   * File I/O
 2191     - Uses improved project file format.  (Unfortunately reading
 2192       previous formats, including 1.1.1, is not supported.)
 2193     - Block files (stored in Audacity project directories) now
 2194       use the standard AU format.  Though some Audacity
 2195       meta-information is in these files, they can now be
 2196       read by many other popular audio programs as well.

 2200       but support for far more file formats.  The
 2201       autodetection algorithms are much more accurate than
 2202       in 1.0.
 2203 
 2204   * Audio I/O

 2206       and minimal chance of buffer underruns while
 2207       recording.
 2208 
 2209   * Resampling
 2210     - Using high quality resampling algorithms, with the
 2211       option of better quality for mixing than for real-time
 2212       playback
 2213 
 2214     - Preliminary support for Time Tracks, for changing
 2215       playback speed over time.
