Description

Super Smash Bros Brawl (and all other games)

RSBE01

When playing Super Smash Bros Brawl at double speed, it also increases the pitch of the audio it plays. This typically wouldn't be a problem, but you can utilize rendering at 2x the framerate - coupled with in game slowmo (or using Action Replay cheats to activate slow motion - to play the game at 120 frames per second on 120hz monitors. This allows crystal clear motion clarity for the people who play these games, and at the normal game speed. In this case audio does and did typically play at double speed but it was more tolerable because the pitch did not change along with it (though memory may be incorrect on this). I'm hoping an option can be added to disable the pitch shift effect. I would use OpenAL as an alternative, but it seems that OpenAL audio doesn't work with Project M in Dolphin.

What did you expect to happen instead?

I'd hoped the game would render at 2x speed with perfectly synced audio at the correct pitch. I think perfectly synced audio is not likely to ever happen for this use case, but I'm hoping the sound playing at the typical pitch will be an option.

What steps will reproduce the problem?

Set Audio Backend to XAudio2.
Set framelimit to 120 (off will also likely work)
Launch a game.

Which versions of Dolphin did you test on?

Latest version of Dolphin as of today. 4.0-3024

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

3.5-2449 has non-pitch shifted audio but suffers from audio crackling.

What are your PC specifications? (including, but not limited to: Operating
