audio latency fix #42
Conversation

Could you get some user testing for this? Maybe on forums. |

I have seriously tested this in a ton of games and find it absolutely necessary for the future of Dolphin. This makes it mostly comparable to using Zelda u-code HLE in most games latency wise. I did notice Midway Arcade Treasures 2 was oddly unaffected, but, perhaps that game just has shit audio even on console. I know this does need testing from more people, but I can confirm pulse audio (with the pulse audio rewrite stuff) and xaudio 2 on Windows both have extremely good audio latency (compared to previous builds) with these changes with no known drawbacks. I tested Mario Superstar Baseball, F-Zero GX, Super Smash Bros. Melee/Brawl, Super Monkey Ball 1/2, Midway Arcade Treasures 2, Wiiplay, Wiisports, Wii Sports Resort among others. I mainly use the fork for playing because the audio latency difference makes a lot of games more enjoyable to me. Once you notice how bad the audio latency is in dolphin, it really bugs you. This alleviates it. |
The usual one is 32->48 khz interpolation. So there is no need in a special 1:1 interpolation only for performance.
OpenAL itself stretch the time on slowdowns, so the Mixer isn't allowed also to change the rate.
Mainline changes attempt 4
This branch will control the interpolation to reduce the latency as much as possible. The current setting are 50ms, but the need to be tested on different plattforms.
