Hi-Fi Audio

*Currently I’m planning to do a demo scene with some Hi-Fi acoustics in it and I want each pair of speakers to sound different (In terms of frequency response and loudness). Is it possible to achieve? *

Since there are no per-actor EQ or cabinet-modelling DSP effects, I would pre-author the audio for each speaker in a DAW, and then play back all the speakers at once in-game (with attenuation falloff and spatialization turned on).
Does that help?

I’ll probably do it that way. Thanks!
