Description
I wonder if you could show how to use wasm of ffmpg avlib to decode 16 channels AAC to a wav buffer for reading by a backend written in javascript to translate the ambisonics 16 channels to binaural.
Other ffmpeg wasm versions i have seen cannot handle streams only completely downloaded files.
I have a website i would like to work on all platforms and not be limited by the local channel restricted AAC decoders.

Research direction
The issue does not name a source file, test, or existing entry point in the tutorial. Start by reviewing the repository's FFmpeg/libav tutorial material and determine whether streamed MP4 DASH input and 16-channel AAC decoding are supported by the relevant APIs. Done should include a documented working path that produces a WAV buffer for JavaScript binaural processing across platforms.
