Ok so i could use some clarification on this subject. when would you use a dynamic eq (i.e. - sonalksis dq1) versus a "static" eq (i.e. - sonalksis sv-315mk2eq)?
Additionally, what about a multi-band dynamic processor (i.e. - sonalksis cq1)? this is a compressor and eq together correct? so you'd be applying compression to the specific freq's you set the eq to?:confused:

I havent used the Sonalksis plugs that you've mentioned but I do use the Voxengo GlissEQ which has dynamic eq. Generally you use it when you need to tame a peak without affecting the sound for it's general duration. Say you need to cut a freq that's peaking at certain times. If you use a static eq by the time you've cut enough to reduce the peak (which only happens are certain spots of the song) the other sections of this track will now be over processed. By using a dynamic eq you could tell it to just apply the negative gain when the peaky park comes in and leave the rest of the track alone when that freq is not a problem.
Hope this makes sense.

So its pretty much acting like a multi-band de-essser ??

Yes that does make sense thanks.

I'm not sure I'd really call it a multi band de-esser although in some cases it could act similarly. For one thing a de-esser is a compressor that is freq conscious. A dynamic eq is the other way around, it's an eq that is level conscious. A de-esser is cutting gain where as a dynamic eq can boost or add.
GlissEQ and the Sonalksis both work a bit differently as well. The GlissEQ just has a dynamics knob. I mainly use it for making cuts for sounds that only are a problem at certain times in the track. By setting the dynamics knob up the eq only works when the signal is peaking loudly. The GlissEQ does add a bit of transients to the signal but overall it's not realyl changing the dynamics too much, just adding or subtracting gain, unlike a de-esser which is compressing.
I had a look at the sonalksis one. It looks like it has full threshold and attack and release control. Haven't tried it yet but again I don't think it actually does any dynamics processing. Looks like the threshold/attack/release is set up to control the behavior of the eq. So you could set it to only boost highs when the highs are below a certain level. Or you could set it up to cut some mids only when they were above a certain level.
So the main difference is that although the eq is being controlled by dynamics the signal itself is not directly being affected by the dynamics like in a de-esser/multiband. There will probably be cases where the effect is similar across both. Best way to think of it is that in a normal eq if you add 10db of 100hz thats what you get the whole time. With a dynamic eq that 10db would only come into effect when the level of the track was a certain way.
