[UE4] Crackling with non-default settings?

Open mastercoms opened this issue 3 years ago • 6 comments

Hello, was testing out the spatialization settings and it seems like only nearest-neighbor is working properly, bilinear is causing horrible crackling.

Hi @mastercoms - Thanks for reporting. I can't seem to repro this issue on our end. Can you provide a sample project where you are facing the issue.

Hi, thanks, will try to find a minimal reproduction.

Hi, I still haven't figured out a reproduction in a fresh project, but after upgrading to 4.3.0 from 4.1.1, and some more testing, it seems unrelated to any one setting.

I'm feeling like it's something to do with CPU usage and buffer underrun, given that toggling certain settings may make audio processing faster or slower. I will keep investigating what could be the cause here.

Inspired by #140, I looked at our Steam Audio settings and tried resetting everything to default. It seems to be fixed for now, but given that the issue doesn't seem to happen consistently (I'm sorry for struggling to pin down this issue!), it may resurface after broader testing.

RealTimeCPUCoresPercentage=50 -> RealTimeCPUCoresPercentage=5

EDIT: yep, someone found a stress test which degrades the audio quality again
