[Audio 2/?] Extract audio samples to wav (#2020)
* [Audio 2/?] Extract audio samples to wav

Co-authored-by: zelda2774 <69368340+zelda2774@users.noreply.github.com>

* How

* Hopefully fix warning I don't get locally

* Pad default sample filenames, comment on the vadpcm frame encoder functions, other suggested changes

* Small tweaks to above

* Remove some obsolete code

---------
