Converting audio files under Linux

Linux has mplayer, an excellent audio player. It’s also handy when you want to convert a sound file from one format to another. The secret is to use .wav as an intermediate conversion, since most audio converters know how to handle that.

Here is the magic incantation for mplayer:

mplayer -quiet -vo null -vc dummy -ao pcm:waveheader:file="output.wav" input.rm

This takes the input file and creates output.wav from it. Once you have that, it’s a simple matter of

oggenc output.wav

to get output.ogg (don’t forget to install vorbis-tools) or

lame output.wav

if MP3s are your bag.
