Don't recall if anyone has already mentioned using open process  but..

But.. If you build your known working string ( ./ffmpeg -i '/Volumes/Audio
CD/1 Audio Track.aiff' '/Volumes/20160518 KJAZ
ARCHIVE MASTER/JULY - JAN 2017/20040315-2-JD0211b.wav') and put it in a
variable tCommand and then do..
open process tCommand for neither
does it do what you want?
