257 5. Compilation instructions
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:
262 http://www.wxWidgets.org/ .
264 The libsndfile library is also required and is included in Audacity obtained
265 from GitHub.
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.
271 Installation of other libraries is optional, see:
272 http://wiki.audacityteam.org/wiki/Developing_On_Linux#optional .
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.
277 To compile on Linux, Mac OS X and other Unix systems, execute these
282 make install # as root
284 To see compile-time options you can set, you can type
285 ./configure --help
287 If you want to do any development, you might want to generate a configure cache
288 and header dependencies:
290 ./configure -C
291 make dep
293 To compile on Windows using MSVC++, please follow the instructions in
294 win\compile.txt in the source code.
296 To compile using Xcode on Mac OS X, see the instructions in mac/compile.txt.
298 For more information on compilation, please visit:
302 or ask at:
303 http://forum.audacityteam.org/viewforum.php?f=19 .

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.
416 Changes and Improvements:
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.
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

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.

455 * (OS X and Linux) Fixed various interface crashes.
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.
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).
470 Changes and Improvements:
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.

482 * "Snap To" settings are now independent for each project.
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).
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.
506 Changes in version 2.0.5:
508 Bug fixes for:
510 * Shaped dither was corrupted and too loud on all stereo exports except FLAC.
512 * Keyboard Preferences: some Edit and Align commands for different sub-menus
513 showed the same name.
515 * Recordings stopped with "Stop and Set Cursor" shortcut could not be undone.
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.
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.
526 * (Windows) On some machines, launching Audacity then recording from the current
527 Device Toolbar input would not record until the input was reselected.
529 * (OS X) Frequent crashes occurred on importing audio files on some machines.
531 * (OS X) Files did not open using Finder "Open with", double-clicking the
532 file or dragging the file to the Audacity icon.
534 * (Linux 64-bit) Fixed a crash when using Equalization.
536 * (Linux) It was not possible to open an effect or other dialog then navigate
537 through the dialog using TAB.
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.
543 Changes and Improvements:
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".
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.
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.
559 * (Windows and OS X) Screen reader improvements for Install VST Effects dialog.
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.
565 * (Linux) Update to PortAudio r1910 fixes memory and other bugs under ALSA.
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.
571 Changes in version 2.0.4:
573 Bug fixes for:
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.
596 Changes and Improvements:
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.
618 Changes in version 2.0.3:
620 Bug fixes for:
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.
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.
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
639 * Toolbar buttons could not be pressed by ENTER
641 * Other interface bug fixes.
644 Changes and Improvements:
646 * The SoX Resampler library (libsoxr) has replaced libresample in
647 Audacity releases, offering both higher quality and greater speed. .
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.
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).
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).
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.
675 * Compilation: cmake is required in order to build libsoxr.
677 * New Croatian translation of Audacity.
680 Changes in version 2.0.2:
682 Bug fixes for:
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.
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.
699 * Effects and Analysis:
700 * Normalize could crash if the track name contained "%".
703 Changes and Improvements:
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.
728 Changes in version 2.0.1:
730 Bug fixes for:
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.
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).
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.
756 * Other miscellaneous bug fixes, including fix to prevent zooming
757 with mouse wheel or ball scrolling the content off-screen.
760 Changes and Improvements:
762 * Shortcuts can now be added in Keyboard Preferences to items in the
763 Generate, Effect or Analyze menus, including user-added plug-ins.
765 * Nyquist Effect plug-ins can now be added to Chains.
767 * New "Paulstretch" effect for extreme slowdown without pitch change.
769 * New "Sample Data Export" Analyze effect for exporting a file
770 containing amplitude values for each sample in the selection.
772 * New Preference (off by default) to import files On-Demand (without
773 seek ability) when using the optional FFmpeg library.
775 * New Preference (off by default) to retain labels when deleting a
776 selection that snaps to the label without extending past it.
778 * (Windows installer) New option to reset Preferences on next launch.
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 .
784 * CleanSpeech Mode (no longer supported) will not now be enabled
785 even if it was enabled by an earlier version of Audacity.
787 * Added Serbian (Latin and Cyrillic) translations.
790 Changes between version 1.3.14 Beta and 2.0.0:
792 Bug fixes for:
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.
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.
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
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.
823 * Other miscellaneous bug fixes.
826 Changes and Improvements:
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.
835 Summary of bug fixes and new features between 1.2.6 and 2.0.0:
837 * Bug Fixes:
839 * Labels now accept lower case "z".
840 * (Windows Vista/7) Pressing Stop after recording could cause a crash.
841 * (Mac OS X) Fixed shortcut keys activating when typing in file open or
842 save windows.
843 * (Mac OS X) Audacity 2.0.0 fully supports Unicode, which fixes an
844 issue where Audacity could not work with folders having non-English
845 characters in their name.
846 * (Linux) Playing existing tracks while recording in mono could cause
847 recordings to be distorted or low-pitched.
849 * New features: There are dozens of new features in 2.0.0, including:
851 * Many effects significantly improved, especially Equalization, Noise
852 Removal and Normalize. Vocal Remover now included plus GVerb on
853 Windows and Mac. VAMP analysis plug-ins now supported.
854 * Improved label tracks with Sync-Lock Tracks feature in the Tracks Menu.
855 Multiple clips per track. Tracks and selections can be fully
856 manipulated using the keyboard. Many more keyboard shortcuts.
857 * New Device Toolbar to manage inputs and outputs. Timer Record feature.
858 New Mixer Board view with per-track VU meters.
859 * Automatic Crash Recovery in the event of abnormal program termination.
860 * Fast "On-Demand" import of WAV/AIFF files if read directly from source.
861 FLAC now fully supported. Added support for optional FFmpeg library
862 for import/export of AC3/M4A/WMA and import of audio from video files.
864 Please visit http://audacity.sourceforge.net/about/features for a full
865 list of features in 2.0.0. You can click Help > Manual (in web browser)
866 in the program to read more.
869 Changes in version 1.3.14 Beta:
871 Bug fixes for:
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
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.
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
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.
906 Changes and Improvements:
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
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.
926 Changes in version 1.3.13 Beta:
928 Bug fixes for:
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.
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 (;).
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.
987 Changes and Improvements:
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.
1011 Changes in version 1.3.12 Beta:
1013 Bug fixes for:
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
1021 * Projects froze if files imported via On-Demand were no longer
1023 * (Linux) WAV/AIFF exports were corrupted if overwriting an aliased
1024 file which had been imported using the command line
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

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
1042 Changes and improvements:
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

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
1060 * (Linux) Improved icon set in compliance with freedesktop.org
1061 Icon Theme Specification 0.6

1457 Import / Export:
1458 * Experimental support for exporting a much wider range
1459 of proprietary audio formats via FFmpeg

1701 Changes in 1.3.0:
1703 New features
1704 The new features in Audacity 1.3 have been grouped into the
1705 following six major categories.
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.
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.
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.
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.
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.
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.
1749 6. Other features
1750 Better performance with large projects
1752 Project integrity check on open
1754 Transcription toolbar
1760 Cut lines
1765 Changes in 1.2.4:
1767 * The File menu now includes a list of recent files.
1769 * The "Generate Silence" effect now prompts for a length.
1771 * Audacity is now built with Vorbis 1.1, which features better encoding
1772 quality and file compression.
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.)
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.)
1780 * "Preferences" command is now in Edit menu.
1782 * "Plot Spectrum" command is now in Analyze menu.
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.
1788 * Audacity now compiles in Visual C++ .NET 2003.
1790 * Other minor bug fixes.
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).
1797 Changes in 1.2.3:
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.)
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.
1807 * libsndfile has been upgraded to version 1.0.11.
1809 * Fixed a bug that caused the program to run slowly when using the
1810 Envelope tool.
1812 * Shift-clicking on a mute or solo button now un-mutes (or un-solos)
1813 all other tracks.
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.
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.
1823 * VU Meters will now always reset when audio I/O has stopped.
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.
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).
1833 Changes in 1.2.2:
1835 * VU Meters added for both playback and recording. Click on
1836 the recording meter to monitor the input without recording.
1838 * Export Multiple - new feature that lets you export multiple
1839 files at once, either by track, or split based on labels.
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.)
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.
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.
1853 * You can now add a label at the current playback position - in
1854 the Project menu, with a shortcut of Ctrl+M.
1856 * Clicking on a label now selects all of the tracks, making it
1857 easier to use the label track to recall selections.
1859 * Windows: Fixed a crash in the Time Track "Set Rate" command.
1861 * Fixed a bug that caused problems with recordings over 45 minutes
1862 on some Windows systems.
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.
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.
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.)
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).

1887 entire project to fit exactly on one page. Try printing in
1888 landscape orientation for best results.
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.
1894 * Fix a bug that occasionally caused crashes when applying effects
1895 to split tracks.

1907 French, Hungarian, Italian, Japanese, Norwegian, Polish, Russian.
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.
1913 * Fix a possible crash when opening or resizing the Equalization
1914 window, especially when using large system fonts.
1916 * Don't allow percentages less than -100% in Change Pitch/Speed/Tempo
1917 effects (fixes a possible crash).
1919 * Fix a crash when the temporary directory is not available on startup.
1921 * Correctly load ID3 tags saved in Audacity project files.
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.
1927 * Fix a bug that prevented Nyquist effects from running when certain
1928 regional settings were activated.
1930 * Fix a bug in the Quick Mix command that could cause old temporary
1931 files to not be deleted.
1933 * Linux: Fix endianness problems in playback on PowerPC.
1935 * Linux: Fix compilation problem in Nyquist on MIPS.
1937 * Linux: Include a more recent PortAudio v19 snapshot (fixes compilation
1938 problems when building with the --with-portaudio=v19 option).
1940 * Two new Nyquist plug-ins: "Cross Fade In" and "Cross Fade Out."
1942 * Other minor bug-fixes.
1945 Changes in 1.2.0:
1947 * New cross-fade effects.
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.
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.)
1957 * Correctly display translated messages in the status bar.
1959 * When the cursor is on-screen, the Zoom In button now zooms
1960 to the area around the cursor.
1962 * Mac OS X: Fixed audio problems on the Apple PowerMac G5.
1964 * Linux/ALSA: Work around a bug in ALSA's OSS emulation that
1965 caused Audacity's playback cursor to move too quickly.
1967 * Microsoft Windows: The Audacity source code should now
1968 compile out of the box on Windows.
1970 * Many new/updated translations.
1973 Changes in 1.2.0-pre4:
1975 * Fixed problems that could occur when importing certain
1976 non-seekable PCM audio files, such as GSM610.
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.
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.
1986 * Fixed bug that led to occasional crashes when using the
1987 time-shift tool in conjunction with high zoom factors.
1989 * Dithering is now only applied on export when it is really
1990 necessary (e.g. when converting float samples to 16-bit).
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.
1996 * The Delete key can now be used to delete the current selection,
1997 in addition to the Backspace key.
1999 * Fixed bug where Audacity didn't ask whether to save
2000 changes if you close the project or exit while recording.
2002 * Mac OS X: Supports Playthrough (listen to what you're recording
2003 while recording it) if your hardware device supports it.
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.
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.
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.
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.
2022 * MS Windows: Fixed problems in trying to set the Windows
2023 registry as non-admin user, for file-type associations.
2025 * Make sure the "Save" command is enabled after changing
2026 gain and pan sliders.
2028 * Updated translations. Added translator credits to the

2069 devices exist, or if the audio device doesn't support the
2070 mode you selected.
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.

2095 while playing or recording. This eliminates many potential
2098 * Fixed ability to cancel Quit button.
2100 * New resampling library, with no restrictions on the maximum or
2101 minimum rate of resampling.
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.
