using two features of ffmpeg I can get accurate cue points out of an
audio file based on silences
ffmpeg -hide_banner -i $AUDIO -af silencedetect=noise=-50dB:d=0.898 -f
null - &> somewhatuseful.txt
and employ them to edit the audio
ffmpeg -y -hide_banner -loglevel error -i $AUDIO -ss $HEADNUM -to
$TAILNUM audio-$(date +'%H')_hours.wav
This is far more accurate then my previous attempts have delivered
My thanks to all who contributed to this code.
