In our application we allow user to upload audio file. currently we support .wav format and we use "sox" to convert the .wav file to gsm for asterisk. We would like to have mp3 support as well. Any recommendation on how to get this done ?
Your help is highly appreciated. Thanks you.
Surely you can still use sox to convert mp3 to gsm/sln/alaw/ulaw format files
Look at http://sox.sourceforge.net/soxformat.html for more info on formats sox support
