Problem with doubling sound

FMOD Studio

Problem, how to fix sound doubling when smoothly switching sound (I do REV for the car) (Fade in, fade out)?

Hi,

Would it be possible to elaborate a bit on what specific event behavior you are aiming to achieve? Could I get a screenshot of how you set up the event in FMOD Studio?

You could use Transition regions and conditions (FMOD Studio | 27. Glossary | 27.170 Transition Region) to smoothly switch sound.

Alternatively, you could have a look at a similar post here, for which I will share it here: Sound plays double

Hope it helps, let me know if you have any questions.
