Re: audioplay and RIFF (little-endian) data, WAVE audio, GSM 6.10, mono 8000 Hz

I was able to convert the GSM file (emailed from asterisk) using sox:

  sox /home/reed/tmp/msg0001.WAV  -s /home/reed/tmp/new.wav 

The -s was required for me. It is "The audio data encoding is signed 
linear (2's complement)".

Then I could play that with audioplay.

sox uses the gsm library to handle this. (I still haven't figured out how 
to convert using gsm utilities.)
