Audio Latency in Unreal Engine

Question

Greetings,

I've successfully integrated Wwise with Unreal Engine. But there is a noticeable latency between user input and the sound start playing.
The latency is about 80ms when using a normal sound card, which is not huge but definitely has a negative impact on how the gun feels. Unreal native sound system has a latency of <40ms (not measured, just from the feel of it).

There is AkInitSettings::uNumSamplesPerFrame() but is there a better practice for Unreal? I want to avoid compiling from source if possible.

Thanks in advance!

Answer 1

We are experiencing the same amount of latency ~80ms.  Would love some help on solving this.  Many of our weapons just don't feel responsive with this amount of latency.

Answer 2

I understand that it has been a long time since this thread was started, but we are experiencing about 88ms latency when using v2022.1.9, while v2019.2.15 has about 72ms latency.

Did you figure out what was the cause of the relatively high input latency in your case? I'm curious to know how to improve this.
