cutter plugin by thomas <thomas@apestaart.org>

SYNOPSIS

This plugin emits signals when RMS level of audio signal crosses a
threshold for a given amount of time

ARGUMENTS

GstCutter::threshold
	level (between 0 and 1) of threshold
GstCutter::threshold_dB
	level of threshold in dB (between -inf and 0)
GstCutter::runlength
	minimum length (in seconds) before plugin sends cut_stop signal

SIGNALS

	CUT_START
	gets sent when the level of the signal goes above threshold level
	CUT_STOP
	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

LIMITATIONS

	* 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
