[asterisk-users] convert from wav or mp3 to gsm

[Danny Nicholas]

A (hopefully) helpful addition to this reply; ORIG_FILE.WAV is a wav49 file.
If the name is orig_file.wav, it is a regular wav file and the sox command
would generate (IMO) a better output like this:

sox <orig_file.wav.WAV> -r 8000 -v 10 -c 1 <OUTPUT_FILE.gsm> resample -ql

I use this all the time and am very pleased with the results...

 

sox <ORIG_FILE.WAV> -r 8000 -c 1 <OUTPUT_FILE.gsm> resample -ql

AIR, * uses wav and gsm with no trouble.  Mpg123 plays mp3 format files.
You can use LAME and SOX to change files between these formats.
