Equalizer before or after HRTF?
(lemmy.ml)
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
