Standard sample rate for native UE5 audio engine

[TabbyCatte]

Hi all! I’m normally using middleware, but am now on a project that is using the native UE5 engine. The UE docs recommend a sample rate of 44.1 - wondering if this is what you’re all using for new projects in 2023. For comparison, currently Wwise defaults to 48k output on new projects. The deployment will be a relatively large scale project. Thoughts?

Thanks in advance!

I’m going to advocate for 44.1. Why use extra memory if you don’t need to?

Also, did you know that audio data compression is applied to your WAV files when you import them into Unreal, and the default is “40% Quality”. If you max that out, and don’t do voice management in Unreal, you’ll probably end up using too much memory.

Also remember that the audio thread and rendering thread are async. If your game is heavy and your audio is heavy (metaphorically), you’ll probably run into performance issues eventually, depending on how big your project is.

Thank you Ben - very helpful and this is what I am doing.
