Amen to that man, the only reason you shouldnt be using Reaper is if you have already forked out mega bucks on ProTools or Cubase/Nuendo. It's an excellent program, pretty much an entire production suite providing recording, editing, mixing, mastering etc. Also allows you to mix audio and midi with as many vst plug-ins as your system can handle. Wav to mp3 is easy in this, couple of clicks and you have it. If you ever have any difficulty with it just go straight to the Reaper forum, its an excellent resource frequented daily by the developers.
