Thus spake Steve Holmes: # I don't think you can... I think each of these compression schemes # have a decode path to the common .wav format but I don't see any way # to go directly. Ogg doesn't know about mp3 and mp3 don't know # anything about ogg if ya know what I mean. Well, this is true, but if you don't want to save the .wav file to disk, you can use - as the filename to write to, which will write to stdout, and use - as the input file for the mp3 encoder.
