cutter plugin by thomas <>
This plugin emits signals when RMS level of audio signal crosses a
threshold for a given amount of time.
As soon as the buffer's RMS is greater than the threshold value, the plugin fires a CUT_START signal.
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.
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.
level (between 0 and 1) of threshold
level of threshold in dB (between -inf and 0)
minimum length (in seconds) before plugin sends cut_stop signal
length of pre-recording buffer
gets sent when the level of the signal goes above threshold level
gets sent when the level of the signal has been below the
threshold level for a number of consecutive iterations of which
the cumulative length is more than the runlength
* RMS value is calculated over the whole data buffer, so
the time resolution is limited to the buffer length
* RMS value is calculated over all of the channels combined
