Whats wrong with DSound and XAudio2?

[mbc07]

This is the side effect to reduce latency in DSound/XAudio2. Sometime ago, one of the developers (degasus I think) did some changes in Dolphin's audio mixer to reduce audio latency caused by DSound/XAudio2. To achieve that, time stretching were replaced by this new technique with doesn't increase latency but make the audio high or low pitched accordingly to the speed. In your case, you manually defined frame limit to a higher value, which resulted in high pitch (if you define it to 10, for example, the audio will have low pitch). To prevent that, just leave frame limiter as Auto and you won't get any problem...

Quote:Is there any way to fix up OpenAL to prevent crackling and latency?

As far as I know, no. The way time stretching feature from OpenAL works inevitably introduces latency and there's nothing to do to remedy this...


EDIT: yes, it was degasus, you can check the original thread here...
