Is there any way for me to implement audio processing?

I’m interested in doing some preprocessing on audio tracks (background noise reduction, speaking detection) before they get sent to webrtc. It seems like there’s no way to do this with the current react-native-webrtc (unless I’m looking in the wrong place)

I notice, though, that there’s functionality for video processing on Android, and a PR open for doing the same for iOS.

Does anyone have any pointers on how I might do this for audio as well? Happy to implement & contribute this back.
