c++ - Recording Audio with OpenAL - Stack Overflow
https://stackoverflow.com/questions/3056113/recording-audio-with-openal
Last time I checked OpenAL it was quite simple. You create the recording device and start the recording going. You then just call the get buffer function. It will wait until there is enough data to fill the buffer and then return when there is enough data. Why not just look at the "capture" example that comes with the OpenAL SDK ...? Share
OpenAL: Cross Platform 3D Audio
OpenAL is a cross-platform 3D audio API appropriate for use with gaming applications and many other types of audio applications. The library models a collection of audio sources moving in a 3D space that are heard by a single listener somewhere in that space. The basic OpenAL objects are a Listener, a Source, and a Buffer. There can be a large number of Buffers, which contain audio …

Audio — Emscripten 3.1.4-git (dev) documentation
https://emscripten.org/docs/porting/Audio.html
Emscripten’s OpenAL implementation (and also SDL1) will automatically listen for a user click or keypress on the document and the canvas, and resume audio for you. That means that audio should start to play once the user does something on the page. (See autoResumeAudioContext () for how this is done internally.) Emscripten-specific capture behavior
