for some reason on my mic'ed tracks (using shure sm57 and sm58 into maudio ozone), i hear a buzzing noise. uhm, is there any way to deal with this, thanks?

Sounds like the mic cable might be lying over a mains (ac) cable... If it is just move it away and the hum will go. Or you might have an earth loop.

Or the mic could be near something like your monitor. Try moving it around.

these tracks were recorded with a friend who recently moved away... so basically they can't be re-recorded. is there anyway to reduce buzz by way of effects or something? thanks.

No, not without changing the track itself to some degree.
You could try hi and/or low pass filters, depending on the type of buzz.
Or parametric eq, or a 32 or 64 band graphic eq (the more bands the better).

Others might suggest a better solution...

Audacity has a Noise Removal tool that works fairly well. You might try that.

Shareware audio editor Goldwave has a noise reduction tool but it tends to flange the death out of everything.

However what you can do in Goldwave you can noise-reduce against the clipboard. What you do is select and copy a piece of the audio that is only the noise you want to remove then tell it to search and find that sound - I would only set it at 50% or less hwoever - otherwise it sucks a lot of the surrounding sound as well. It's a play-off between aural cleanliness and flange horror, basically.

What about finding the fundimentally annoying frequency and then inverting the filtered wave form over the other audio track?

the usual problem with that (swstat) is that most forms of noise are too changing/complex to filter correctly, and it's a somewhat more complex problem than all that. if it's a small frequency band that the problem occurs in it's easier, but it's generally not.
