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.
I succeeded to route it thru fl studio were I can do anything I want with the sound.
Well, thing about Viper is that it’s superlightweight, free, and sounds great. I would still give it a go. It has comp, EQ, 3D/stereo image, reverb, convolver… I combine it with RAs own filters (which I mostly use for custom EQs) and the results are fantastic. Cool that you got the FL thing working anyway.
I use equalizerAPO, it’s learning curve is a bit steeper but you can code anything out of it. I made Dolby upmixers for ProLogic tracks but also works for stereo tracks
