how about… Breakaway Live. 😀 Go into your Settings –> I/O Config and change the "Mode" from "Core 1-4: Broadcast Mode" to "Core 1 Speakers, Core 2-4 Broadcast", and click Finish button at the bottom.
Then when Breakaway Live main window comes back on screen, click Settings and you should see this:
Click on "Parametric Equalizer" and there you go. Don’t forget to save your settings in case you ever need them again, or want to play around with different versions of your correction EQ.
What I do to calibrate is run slow sine-wave sweeps up & down and listen and EQ so that there’s no hills or valleys, and so that no "section" of frequencies (like bass, mids, upper mids, treble) are louder than another. Also don’t forget to give yourself enough "EQ Headroom" to prevent distortion if you’re turning any of the gains up, instead of down. (you’ll probably have a bit of both up & down)
