1 cutter plugin by thomas <thomas@apestaart.org> 2 3 SYNOPSIS 4 5 This plugin emits signals when RMS level of audio signal crosses a 6 threshold for a given amount of time. 7 8 As soon as the buffer's RMS is greater than the threshold value, the plugin fires a CUT_START signal. 9 10 When the buffer's RMS level drops below the threshold value for a consecutive run length longer than the given runlength, it sends a CUT_STOP signal. 11 12 When a pre-recording buffer is used, the plugin will delay throughput of data when it's in "silent" mode for a maximum length equal to the pre-recording buffer length. As soon as the input level crosses the threshold level, this pre-recorded buffer is flushed to the src pad (so you can actually record the audio just before the threshold crossing) after sending the signal. 13 14 ARGUMENTS 15 16 GstCutter::threshold 17 level (between 0 and 1) of threshold 18 GstCutter::threshold_dB 19 level of threshold in dB (between -inf and 0) 20 GstCutter::runlength 21 minimum length (in seconds) before plugin sends cut_stop signal 22 GstCutter::prelength 23 length of pre-recording buffer 24 25 SIGNALS 26 27 CUT_START 28 gets sent when the level of the signal goes above threshold level 29 CUT_STOP 30 gets sent when the level of the signal has been below the 31 threshold level for a number of consecutive iterations of which 32 the cumulative length is more than the runlength 33 34 LIMITATIONS 35 36 * RMS value is calculated over the whole data buffer, so 37 the time resolution is limited to the buffer length 38 * RMS value is calculated over all of the channels combined
