Home > EQ
This is a page from our old website that remained on the web even though our front page no longer linked to it. I found I still referred to it regularly, so I'm keeping it out here and re-linking it.

I'm no EQ expert. In fact, I've always been kind of a minimalist in that regard. But then I saw a few tips here and there, tried a thing or two and decided I needed to learn more. I compiled this list from several sources and will continue to tweak as I try things out.

Generally speaking, I think cutting frequencies works better than boosting. It doesn't seem reasonable that you could take a lousy vocal track and make it "sparkle" by twisting a knob. You're probably better off trying to put a better label on the "lousy" -- nasal, maybe, or boomy -- and try to eliminate that specific problem. Maybe the sparkle is just hidden under the bad stuff.

Anyway, here's what I dug up. Remember, I used several different sources so not everything will be perfectly complementary.
