Audio stuff

pitch_bendable = true,

Looks like it gradually adjusts the pitch, capping at ±100. Didn’t track down how it determines the adjustment, though.

persistent = space (only found space. can be anything else here and what does it do?),

It can also be gameflow, but as far as I can tell, persistent isn’t used (at least, not as far as rumble_freighter goes, and the tests it makes ignores it).

msg (obviously linked to some speech sound)?

The hash of this is what you see in the AUDIO utf files (UTFXML reads these values to generate meaningful file names).

There’s also lod1 and lod2, read as strings and converted to hashes, so I guess they’re the same as msg. Doesn’t look like they’re used, though.
