Converting Audio for Yate

Despite its name, the wave module (as in wave/play/...) does not actually support wave files. It can however process raw 8kHz single channel signed-integer PCM audio data. And this is how to create such files:

sox sound.wav -t raw -r 8000 -c 1 -e signed-integer sound.slin

I like to wrap things in shell scripts for simple reuse:

sox $1 -t raw -r 8000 -c 1 -e signed-integer $2
