Hello, I’ve made posts on this forum before. this time I already have an engine sound setup of a Nascar engine that I’m going to use to record back in audacity while the session is playing back the loops of audio,

The only issue I have is I’m wanting to know how to create accel and decelerations using parameters in Fmod studio? Does anyone know about this in Fmod? I already have an rpm parameter setup.

Btw, I’m just using Fmod not Unity nor Unreal engine along with it?

Hi,

In our example project we have a `Car Engine` example which uses a `RPM` parameter to display acceleration and declaration. The example project is included in the download of FMOD Studio and can be found at the bottom of your recent project list:

hope this helps!
