I'm trying to transcode a .wav to a .gsm using SOX v14.0.1. What I get
is a completely garbled when using playback in FreeSWITCH. I have
verified that at least one other application (Quicktime Player) can in
fact play the resulting .gsm file.
I have tried the following:
sox william.wav -t gsm william.gsm
sox william.wav -t gsm -r 8000 william.gsm resample -ql
sox william.wav -t gsm -r 8000 -c1 william.gsm resample -ql
And I am playing the file using:
originate sofia/internal/1000 at 192.168.1.1
Other formats such as uLaw and aLaw (-t ul and -t al, respectively) seem
to work fine.
Does anyone know of a set of parameters for SOX that will make this work?
At the end of the day, I just want it to work, so if anyone can
recommend any other known/good command line tools to encode GSM that
would be fine too.
