Re: split stereo by channel and silence

the reason why is i'm trying to use an ASR( Kaldi to be exact) to
transcribe the audio. it seems to work better on short audio clips which is
why the split on silence and keeping the channels separate makes it easy to
know who the speaker is, plus it was was unintelligible to my model when
they were speaking over each other in a single mono file.

i'm still very new to figuring out how to use Kaldi, so there easily could
be better way within that tool to handle this.
