Hi Aleksey.

Got a question for you.  As you have no doubt seen on the UAD board, I'm liking CurveEQ more and more as time goes on.  Now, however, I'm finding myself in a position more and more often where I'm wanting it to do somthing that it can't yet do, and I'm wondering if you have any suggestions or perhaps even think this might be a good idea to implement.  It doesn't actually sound like it would be that hard to code.

Creating mixes, as we all know too well, is about getting sounds to sit together well.  A lot of times, what this means is that we want each instrument to have its own space in the mix.  A simple example is that we might have a kick "living," or sounding really good, with a peak at, say, 80 hz.  Thus, we often might want to notch out a bit of the bass at that frequency.  This kind of thing is, again, as we all know, a frequent requirement of the mixing process.

What I would LOVE for Curve EQ to be able to do is to take match the curve of a sound, say, the kick, and then be able to present the *inverse* spectrum, which I could then apply to the bass, or any other instrument fighting the kick down there.  In other words, where the spectrum of the kick might show a 6db rise at 80 hz, the inverse would show a -6 db dip at that frequency.  Since all the points of your spectrum match feature are freely movable, it would be really easy to make adjustments in frequency ranges where this interfered too much with the sound of the instrument you're eq-ing.

I think this would be an incredible help in getting sounds to fit together well, and would be yet *another* feature in CurveEQ which can't be found in any other eq.  This is a task at which mix engineers spend hours -- CurveEQ could step in and make it incredibly easy.

What do you think?

Best to you,


Ack!  Skip it.  Had the brilliant idea (duh!) of matching any instrument to a pre-captured spectrum of white noise.  I think this does exactly what I want.  Easy, too!



Actually, I'm going to add an "Inverse" button so that things are still simple.

hehe empty planet i am using curve eq for exactly what you described a long time already ;) its plenty easy to do so, just analyze the sound (the one you want to change later, your bass for example) then analyze the bassdrum. fine, now save your preset and go back to your bass and apply the saved eq there now. thats all the trick, no need for an invert curve.


ah btw empty planet, can you explain me what exactly you wanna do with your whitenoise matching? i am interested in that, would be nice, thnx :)


Hey DaBug.

I think what you're trying to do is the opposite of what I'm trying to do.  Matching the curve of the kick to the sound of the bass is going exactly in the wrong direction, at least as far as my mixing is concerned.  The challenge for me is to make each instrument sound more distinct, not more similar.  But if it works for you, that's great.

White noise is basically a straight line across the spectrum, thus if you apply this to the curve of one of your instruments, the CurveEQ, in attempting to compensate in order to match that flat line, presents you with an inverted curve of your instrument's, to be used for the reasons described in my first post.


hi empty planet. no, its not the opposite way. look: take an sound, for example and bassdrum, now anaylze the original with CurveEQ and save that preset. now apply an Equalizer on exactly this same sound and boost some frequency about 12db or something very high. now go to CurveEQ again and analyze this modified sound as destination. you now see that CurveEQ makes a -12db at exactly this frequency, but instead applying this preset to the sound you modified, you now go to the ORIGINAL sound again and apply it there!! and what do we get as result now? the original sound now has a -12db dip at the frequency as the other sound with 12db has it as peak. and they both sit perfectly together now.  So this is exactly what you are looking for, a REVERSE curve! now you just need to do it as i described before. see what i mean? no need for such a switch.  Logical thinking roxx ;))
