An EQ which makes the output volume stay the same as input? Any?

Isn't it going to vary (the volume change) based on what kind of material you are eq-ing and how it changes through the length of it? That said, it seems like what you are asking for could be made to act automatically, but come on, how lazy are ya ? ha-ha.

Your best bet.

(Other post about original content is still 100% true.)

Harbal will do this, but not in real time:

Voxengo HarmoniEQ has a feautures that displays the input/output difference in dB to make it very quick to match the levels:

matching the levels to hear the difference is a vital step in judging the change in sound. Its very easy to just boost and imagine it's better!

Not a matter of effort.
HarBal made me realize that when such correction is performed automatically I can focus on the harmonic balance more carefully.

But its a standalone.

Thanks for the Byquist link!! It just recently after changing monitors to ART tweeter driven that I noticed the hats are too sharp.

And it compensates. Thanks!!!

I am about to release PEQ, an equalizer that automatically and fully compensates the output level according to the current EQ settings AND the material being played back. In other words it "listens" to the signal and bases the compensation on the frequency content present. For example, low-shelving 100Hz by 20dB doesn't change the compensation on a hihat track, but it will on a bass track. The cherry on top is that the compensation even takes the non-linearity of human hearing into account.

The bottom line is that the perceived signal level remains the same whatever EQ madness you unleash upon it, which makes it much easier (not to mention faster) to hear what your settings are actually doing to the sound.

Besides that it also features a number of "vintage" EQ curves, selectable phase behavior (including linear phase), a dynamic EQ mode, full automation, and of course A/B comparisons.

PEQ is in late beta testing and will be released within four weeks as VST/RTAS on Windows and VST/AU/RTAS on Mac.

djex - I'll be interesting in trying it out when it's done. The concept is valid, I just had to poke fun at someone who sounded like they expected their e.q. to just do that for them. But after thinking about it, I'd be interested in trying something like that out, if it works well and saves time/effort, then more power to it I guess.

Hey, no problem--I've been around KVR longer than today.

Thanks for your interest, take care & you'll hear it when it's ready!

there is one I know, but I guess this company is no that highly regarded around here:

crysonics Cry'Q has a volume preserving button.

I am curious too!

Nyquist has one fault - it does sometimes crashes when wrapped with Novation Nocturn.

This is terrible mixing technique, your better off dropping the rest of your levels to balance.

Why add more gain to a digital situation?

TOTAL · Post by **TOTAL** » Thu Sep 11, 2008 9:26 pm

Just try it. If you add in 1khz the rest gets reduced. If you lower, it is raised elsewhere. That's what you do anyway when you EQ but want to maintain the overall audibility.

I know what your saying mate.

Listen closely to the gain change. Its the same thing with makeup gain on a compressor. You turn up the volume, lower overall bit rate. This is a digital problem. In analog it doesn't matter much. A really tight mix, of a digital track, pre-mastering, is quiet. The less you put in your signal flow, the less gain you add into your situation, the better off you are.

IMHO...

I know you could add volume after eq... But still, you will get a cleaner mix if you LOWER volume to balance.

IMHO...

cheers

Overall, I agree: the more you modify material in digital realm, them more you degrade it.

But if you decide to EQ, I assume you have a reason.

Now, let's say you want a lead sound to be narrowed to the midrange.

In traditional EQ you cut the bottom and cut the top. And if the volume gets too low you compensate it.

Do the same in nyquist. The difference is you have a choice whether to compensate it manually or let it be done automatically. But once you draw a mountain, it gets surrounded by valleys.

In any case the same process takes place.

In either kind of eq it is generally better to 1) remove parts of spectrum and then compensate if necessary rather than 2) add in some freq and reduce overall.

But is it because I have been recently sparing both with eq and track volume or because nyquist intelligently performs the whole operation according to above pattern 1 no matter if you draw one mountain or two valleys, I can imagine it degrades the material but I don't really hear it. So for my purposes nyquist kind of eq is appropriate. Same as making music in 16 bit, so far.

Or do I still miss your point?
