I am building a media player app, and I am working on an offline playback feature, but I still want to support streaming. Ideally, I would be able to capture the audio data coming in from the stream and write it to disk. As it is, I have no access to that data, and I have to download the entire media file a second time if I want to write it to disk for offline playback.

Seems similar to https://expo.canny.io/feature-requests/p/streaming-audio-input but from the lack of detail specified there, I can't tell if it's the same thing. Also similar to https://expo.canny.io/feature-requests/p/expose-audio-recording-bitstream-to-js, but for playback data rather than recording data.
