Getting access to the currently played buffer bytes would also be helpful to create visualisation plugins like WinAmp had. In conjunction with react-gl there are a lot of opportunities.

One way to make them accessible to the JS side would be the transfer them using a SharedValue or a GPU snippet like [react-native-vision-camera](https://github.com/mrousavy/react-native-vision-camera) uses in its frame processors.
