Sorry if I didn't understand it right. Doesn't it add up two signals into one? I want to see two different spectral curves in a single display to compare. Maybe I can compare two curves in an analzer plugin such as Span or Prism, but I want to know if there is a free eq vst to do that.
Well, If you're comparing mono signals you can send one to the left channel and one to the right channel of the third track and use a stereo analyser/stereo eq or whatever. That's what I was getting at to see if it helped you out.

I don't know if you're looking for something like this. Called The Masker and it does what I think you want it to do (except display frequencies). Downloaded and installed but haven't tried it yet.

If you don't use Reaper, you can load this script (because it is essentially a script) into ReaJS.

Hey! This is probably the best solution closest to what i wanted. I installed Reaper a few weeks ago and still in learning basics. Currently I'm using Waveform Free mostly. I tried it with Aveform and it seems working fine. Does ReaJS work even if I uninstall Reaper?

Hmm, I never thought of routing left the signals into left and right separately. That is interesting solution! I'll definitelt try it later.

As far as I know, TheMasker is for removing or reducing overlapping frequencies. For example, when a guitar and a vocal track is being played simutaneously and the vocal track needs to stand out and the guitar track's spectrum is all over the vocal track, it automatically removes the overlapping frequencies. That's what I understood.

Yes, it's a regular VST plugin.

That's great to hear. Thanks!

The Masker says it removes clashing frequencies, but there's a knob that let's you Boost them and hear what's being taken out.

As far as i know, only paid version of Nova or SlickEQ has match function.
They are worth much more than their price is, for reals, if you are doing stuff regularly. All of TDR are platinum :)
