split audio track using silence detection

[mogrifier]

This is needed for sample processing. Turn one big file into a bunch of little one but using silence detection to find start and stop of each audio segment with good data. Not just silence detection, but finding good audio, too.

Need to define a window size for evaluating, I think. Slide window and check again. Not looking for zeroes but for overall low amplitude in the window. A running average would detect falling and increasing amplitude. Need to know if positive or negative curves regarding the center line. Must be algorithm in DSP land.
