There are a number of threads here asking about low-latency audio. It would be really great if there was a pathway to getting responsive audio, and if the audio team could help us out.
For example, coming from a pro-audio app background, I’m used to setting my buffer size and getting the delay that I expect. A 256 sample buffer / 48000Hz sample rate should get me a input → sound delay of about 5-6ms.
But in UE, I set the buffer size to 256 and it still has a 150ms delay. So, could there be some documentation on why that is? can we do anything about it? or no?
This page on low latency frame syncing tries to explain input latency with regards to game logic and rendering, but it doesn’t address audio.
Since audio is so dependent on the platform, can there be documentation on each platform? Why can’t I set my buffer size less than 512 on a Mac, when it so easily handles that in other apps? what driver is being used on Windows? what can I expect if I port my game to Xbox?
So many questions. It would be great to see some documentation on it.
