Tupper - VRChat Head of Community: Well, we know tha AVPro itself supports audio filters just fine, so I guess its something about how VRC has it set up, which is unfortunate.

I double checked using the AVPro trial and it played through audio filters via the provided Audio Output component and with the Windows-specific settings set to Unity Audio.

orels1: The difference between your setup and VRChat's is that VRChat adds the AVPro AudioOutput component at runtime. This means that it's always the last component on the GameObject so it runs its audio code last. The AVPro AudioOutput component uses OnAudioFilterRead to inject the audio from the MediaPlayer into the AudioSource which since this happens after the other audio filters have run they cannot affect it. Unity doesn't expose any methods for rearranging the order of components at runtime so we can't just move the AudioOutput to be above the filters.

TCL: ok, that's fair, altho i just tested this shitty code for adding at runtime, and it seems like just moving it up and toggling the effects on and off on the same frame - makes it re-apply them

But i guess you can't just shove an internal method without some hacky solutions :thinking: Thanks for details tho! At least it helps to understand what's going on :P

TCL: At this point I guess it'd be more of a feature request, but if you can't reorder the AudioOutput that's created by VRC, it would be nice if we could add an AudioOutput component ourselves. So the AVPro AudioOutput component would need to be whitelisted for SDK3 worlds (it's already whitelisted for SDK2 worlds) and the VRCAVProVideoSpeaker component would need an option to point to a Component reference for the AudioOutput, or a GameObject reference to the game object the AudioOutput is on to keep the SDK decoupled. The VRCAVProVideoSpeaker would then hook up the AVPro media player that VRC creates at runtime to the AudioOutput.
