this sox command line does the work on audio sampled on an Atari STe with a Mastersound cartridge:
> sox JOAN100.AVR -r 44100 -b 16 joan100A.wav silence 1 0.1 0.1% reverse silence 1 0.1 0.1% reverse
sox reads the .avr header, then upscales to 44.1 khz / 16 bits: we also trim silence from start and end.
here it is embedded as an Automator app for OSX Mojave. I'm sure this will be broken in later OS'
for AVRs that come in smaller than 1kb or so, I think that the trimming associated with remove silence trick used here results in an empty file. I'll get to that
