Hello. Iam just wondering how the sound filters in retroarch works. What I would like to do is to have a multiband compressor (among other) filter and my question is how this would be possible? I guess I cant just take any vst effect (dll file) from eg FL studio and use? If so, how do I change the parameters then?
Correct, RetroArch uses its own filters libraries. You can customize, mix and match different effects using the *.dsp files (like this one: https://github.com/libretro/RetroArch/blob/0f4744bed7cdb2f86e0a533f9ccdc263fa3a270b/libretro-common/audio/dsp_filters/ChipTuneEnhance.dsp), which are just plaintext files that tell the filter libraries how to behave.
Ok thank you. Maybe it would be easier if I route the sound thru fl studio if I want some special effects.
