Documentation for audio libraries?

[warcow105]

I was wondering if there is any plan to add documentation for the audio libraries. Even some basic description and hints for usage in the files would be a big help.

was looking for the same. this is too convoluted to figure out just by having a read at the code. I'm struggling with changing the audio i2s sample to read&write to an i2s IC.

Seconding this, for what it's worth. I can tell that the audio I2S code is very flexible, but it's really difficult to make any modification. Even some limited docs on what the various things mean and how to use them would be amazing.
