I have a “Corsair Void Elite” headset.
For the last few years, I have been using an HRTF alone to apply 7.1 Audio to my headset. But now I want to apply equalization from AutoEq.
Do I apply the equalization before or after the HRTF transformation?
Notes:
- I am using a PipeWire filter chain on Fedora Atomic

I don’t know that I’ve come across anything official for this case, but from my experience in audio engineering, you typically want to put the most “artistic” effects early in the stack and the most “utility” effects toward the end. So in this case, if I were you, I’d put the 7.1 effect at the end since it’s not likely to change often or be adjusted.
At the end of the day, test both and if one sounds better than the other to you, go with that one.
