Here's a quick tone test I recorded a while ago. The tune is Periphery - Icarus Lives. http://picosong.com/nCTP/
If you got a couple hund to drop then you should get the M-Audio interface. It's got inputs for musical instruments including microphone and connects to your computer with USB. But your computer has to be fast enough to run it. It will record your music in amazing quality. It's what I use and I'm a rapper. I use my homies studio as of now cuz I don't got a pre amp and my mic broke lol (stupid dog). I got monitors and everything so yea.
Here's a song I got recorded a couple months ago. It's my true beliefs on the crap we call music now. Especially when it comes to rap music.
