I use one called CoolEdit 2000 combined with the Studio Plug in... gives me a four track recorder on my computer... just starting to play with it...Have used cooledit for a while.. great for recording yourself, mono or stereo, wave or mp3 or .ra files (plus a host of others). The Studio plug in is new for me, looks pretty cool though. Allows me to mix up to 4 tracks into one stereo mix......
