How do you go about getting rid of background noise in a track? Is it even possible?

Yes. I put on a low pass filter on the bass drum and that got rid of a lot at the expense of some of the drum, but for the overheads I can't think of what to do.

It's possible, but not easy. Who you do it depends on what type of background noise you're talking about:

If you're talking about more transient types of noises like a door closing or something like that, those are probably the easiest (though still not real easy to do well).

If you're talking about ambient room noise, computer fans or air conditioning, or that kind of thing, it's rather harder, but possible. If can re-record the problem track(s) it would be faster, but if you cant' fixes to the current tracks can be made.

If you're talking about removing bleed from other instruments, there are some tricks that can possibly be done, but it's *extremely* difficult to the point where your'e probably far better off re-recording the probelm track(s).

Let us know just what kind of noise you're referring to, and maybe we can narrow down the prognosis for you.

If you have a program like Wavelab then it comes with 'Nenoiser' and 'Declicker' which are bloody good little units. They've never lost a fight against background noise.

It is bleed over from guitar in drum tracks. Especially the overheads picked up my guitar quite a bit. The bass also picked it up but a lowpass was able to bring that down quite a lot. The overheads are the problem. I tried a high pass and it worked but the cymbols sounded like shit after.

It isn't that important of a track to tell the truth. It was a jam and I thought I would like to maybe re-record my part and maybe add some bass and such. Re-recording his might be the easiest route, though it would be an interesting exercise to try and clear these up a bit.

Attaching a sample of one of the worst tracks....oh, guess not. Shucks.

Not good news. Even if it were the other way around - drums bleeding into guitar - it would still suck, but it would be somewhat better. But guitar bleed (I'm assuming electric here) is about as hard to get out as my ex-girlfriend.

Sometimes you can use some phase cancellation to remove the bleed by summing a volume-controlled phase-inversed signal from the offending track with the raw signal of the affected track, but that trick has only intermittent or partial success at best.

I'd say it'd be much easier and better sounding to just re-record the drum track if you really want to save it.
