They don’t. This was one of the fundamental design principles laid down at the
very inception of the project: the audio store contains *only* audio; all other
metadata goes in the SQL database.

It's a matter of standards-compliance. The European Broadcasting Union has
codified the standard audio storage format for use in professional broadcast
storage and play-out systems. Rivendell (as well as many proprietary systems)
adhere to these standards:

So, while it’s common short-hand in many shops to use ‘WAV’ to mean
‘uncompressed PCM’, WAV is actually just a container format (specifically, a
Microsoft RIFF format, similar to AVI and similar formats) that can enclose
many different audio encodings.
