Leaning about audio formats

[erwanvivien]

Hey 👋

First of all, awesome crate, it is really powerful, I love it.
Second of all, I am kind of an audio noob, I'm trying to learn audio.

I was checking the source code of symphonia-play and wanted to see how you were writing the audio samples to the host machine ring-buffer (which I assume is provided by the OS for you to write on)

I came upon this code: https://github.com/pdeljanov/Symphonia/blob/a5ac0ec/symphonia-core/src/audio.rs#L819-L864 (copy_interleaved_*)

I wanted to know why the interleaving is necessary and just to be sure, when you create the audio_output using output::try_open(spec, duration).unwrap() those n_channels count are use for the interleaved decoding behind the scene, right?

As a more general question, where can I find good resources to learn how audio works in general and learn some audio algos like BPM solver for example

Again, thanks a lot for the library 💜
