> Yeah, just use the WaveOut plugin that comes with it.
You could, if you want almost no control over quality and nothing even close to the full range of quality you could get by using something such as the free LAME MP3 encoder. <img src=smilies/magbiggrin.gif>
LAME is very good as MP3 encoders go...if you want an easy to use frontend for it, go get something like the easy to use program Audiograbber (which is also free). I generally use it as my CD ripping program.
If you're looking for MP3 to WAV conversion, try WinAmp's DiskWriter plugin (should come with one, if not all, of the free packages).
If you're looking for WAV to MP3 encoding instead, then as someone else has already mentioned, LAME is a good choice. If you don't want to fool with command lines though, you'll want a front-end of some sort for it.
