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.

Robert
