Hello! We’re getting a parameters finalValue to scale an object along with the sound but when muting the audio in the game window tab OR setting the master volume to 0 via our FMOD vca’s, the parameters finalValue return to it’s default value even though we can see the parameter still being modulat…

When you mute something in FMOD, the audibility calculations try to work out whether any given instrument can be heard, if it can’t, that instrument will be virtualized.

Hey, no worries about the delay! I’m a bit slow on the reply myself hahaha We have done some more testing in a completely fresh unity & fmod project and are getting the behavior where finalValue goes back to default whenever we mute the game window despite all our attempts and tweaks. This is the …

Thank you for sharing the project! I investigated the behaviour, and here is what I found: FMOD updates automatic parameters and calculates each parameter’s final value only while the Studio system is actively processing audio. In the FMOD Unity integration, the Unity Editor’s Mute Audio button is…
