As the title says, I'm using Fabfilter Q3 and it has a dynamic function. Some people said the dynamic EQ and the multi-band compressor are mostly the same.
Thus, if I use a dynamic EQ, do I not need to use any compressor?

 

No exactly. EQ bands mostly have bell shapes, while a multiband compressor has filters with a slope at both sides. This almost always leads to areas with different shapes. You know what I mean?
The compressor bands look more like a square with soft corners.

i never use dynamic eq
for example i usually send my kick and base to a buss drop an instance of fabfilter mb on it and 9 of the 10 times it works
it sound like it glue's the kick and bass togheter

 

I saw a video with a producer of Psychadelic Trance using this method, kick and bass processed together.
I prefer to separate these 2 elements for better control.
Maybe I should give it a try to see what happens in this case?

 

This is a good read from izotope. If you want to know more about differences between dynamic eq and mutliband compressors.

Edit oh @shankar posted this link already.
never mind.

 

I almost always use a dynamic EQ.

That's not at all what I've ever used a dynamic EQ for and therefore it's not interchangeable.

 

how and why do you need dynamic eq im just a hobbyist and im actually not so good with music theory and all the technical stuff
im incapacitated for work so I have plenty of time

 

Typically when I make a new kick, I'll run a 909 through a few dynamic Eq's and distros - - First Eq normally kicks out the bass and foucses on the punch and highs of the kick. Distort that and apply another Eq that tweaks it for when I start Eqing the bass back in.

 

On principle to tame temporary spikes.
Mostly boomy low freqs of the bass and when instruments/vocals add up some freqs, temporarily.

 

Useful info.

 

Technically both can be used to almost replace the other. In practice depends of what you want and can do.

 

Great details. Thanks!
