Audio is exported with the wrong frequency #3

Open TwoSpacesSG opened 2 years ago

TwoSpacesSG commented 2 years ago

This is all from memory so apologies for inaccuracies. Sound effects from bigfiles (specifically WALL-E for PC was tested) are exported to WAV with the wrong frequency, meaning that it sounds different in pitch and speed compared to how it is in the game - or at least I've found some familiar WALL-E and Ratatouille (!) sfx that sounded sped up like that to me. I believe there was some discussion about how there's data in the classes regarding frequency, and the dpc tool doesn't know about it, or something like that.

After some investigation, it appears this is due to a change in the default sample rate between games. FUEL uses 44100 when no sample rate is specified while WALL-E uses 22050. When proper WALL-E support is implemented, the Sound_Z implementation for WALL-E should take care to change this value. As of now, only FUEL is officially supported so no changes will be made; however, I will leave this issue open for reference while adding WALL-E support.

We should have a FUEL backend option for the default sound sample rate to use. By default, it should be 44100 but should be able to be overridden.
