Equalizer APO (and the Dolby EQ app that I've also tried) seems to only be working globally, i.e. once I enable it, the entire system and every single program uses it. That messes up certain things like OBS audio when I'm streaming or recording. Sounds become muffled, some audio gets equalized multiple times - first by the music player, then by OBS, then by the viewers' computers etc.
For this reason (and as a personal preference), I don't want to equalize most programs, save for the few specific ones, like Spotify (which for some reason still lacks an inbuilt eq). How could I go about achieving that?
