Woah, really? I don’t think that’s happened to me, but I’ll definitely check that ASAP just in case, but I read on the unreal engine documentation that 16/44.1 (or 22.05khz) is the recommended setup for a file type, the engine will internally convert anything other than 16/44.1 PCM .wav into 16/44.1 PCM .wav. I have no idea why it’d pitch shift for you though- did you have your project settings at 16/44.1 before bouncing your audio? Or did you bounce a 16/44.1 from a 16/48 project? Maybe that has something to do with it? I know I’ve run into pitch issues putting 48khz onto 44.1 tracks or vise versa.
