Can FMOD make the playback rate of audio faster without changing the pitch

If yes, have the corresponding video or documentation? Thank you very much!

You can but you will need to automate a pitch shifter effect (within FMOD Studio or via the API if you are using FMOD Core) to counter the affected pitch (in other words, pitch (speed) the sound up then pitch shift it back down).

You can add effects in FMOD Studio by right clicking in the deck with a track selected and clicking “Add Effect” > “Pitch Shifter”. In the FMOD Core API you will need to add the DSP yourself.
