Weeks back I faced a problem with playing my WMA files on Android. Due to DRM related issues Android does not support WMA on the fly. The only app I could find to play them was PowerAmp. But I was reluctant to waste some MBs (~ 6MB) on my phone just to play WMA files. While searching for a good converter on Ubuntu I came across Audio Convert, a script which converts audio files using a GUI. I have tried converting only WMA to MP3 till now and it works like a charm. Uses lame in the background to convert to MP3. By default it converted at minimum 128 kbps bitrate which I tweaked to 64 kbps (modify the audio-convert file to add kbps as “quality” to pass to the lame converter. Open-source goodness!). Can be installed as a nautilus extension. Can convert a single file as well as a whole directory of audio files with the same options when used with a wildcard like “*” from the terminal. A great solution for my problem.
Audio Convert can handle convert wav, ogg, mp3, mpc, flac, ape or wma files into wav, ogg, mp3, mpc, flac or ape files.
