What is a good Windows spectrum analysis program that I can use with my Focusrite Scarlett 2i4, to check the spectrum of some of my filterbanks?

Posted Image, might have been reduced in size. Click Image to view fullscreen.

here your soundcard used as scope input, also has the ability to visualise the power spectrum.

HERE i’m using this (free) software in a demo.

RMAA should be able to do it. The one I have is free and I'm running it under win7.

No idea what "Focusrite Scarlett 2i4" is, so I can't comment on that bit.

It seems you've found what you are looking for, but I wanted to mention another program if someone else finds it useful like I have. It's called Sonic Visualiser, and it's free software that runs on Windows, Linux and OS/X.

However, it does not work in real time, i.e. it can only analyze a recording, but with several types of analysis and overlays and stuff.

Had some time, so I tried running spectrum analysis on the Direct Outputs that the Serge Resonant EQ module provides. (I have the Eurorack version, with the sliders.)

The results are... decidedly funky. It's interesting to see directly how the filter slopes, with only one opamp stage, are quite shallow. (The Yusynth FFB has two opamp active filter stages per frequency. The Serge has one.)

All these analyses are with all the frequency bands set to either max (Yusynth FFB), or midway (Serge Resonant EQ, I didn't want resonance.)
