I'm trying to record an acoustic electric guitar into ACID Pro 4. I tried putting a mic up to the guitar, and (possibly due to it being a ****ty mic) there was too much background buzzing. So I tried hooking it up to an amp and micing the amp, but this caused it to not sound as clean once it was loaded into ACID.

I tried plugging my guitar into the amp and instead of micing the amp, plugging headphones into the headphone jack, and it sounded BEAUTIFUL. So I ran a line from the headphone jack so my sound card microphone input, and while the guitar sounds beautiful, theres a very annoying buzzing in the background, which I assume is due it not being a very good sound card? (Dell Laptop). My question is is there any way to get rid of the buzzing? Like EQ it out or something? I have no idea how to do anything in ACID really besides record in and slice and stuff so I'm not sure if it has anything to help with these sort of cases. Or, maybe I just need to tweak with the Windows Recording Controls.

Here is a link to the sound file. It doesn't sound too bad on low volume but on high volume it's almost intolerable. But this is the exact guitar sound I want, I dont want to lose this guitar sound.
