Is there anyway to make the sound goes faster or slower? Im making Footstep SFX and I wanna make the sound run base on character speed

Hi,

Adjusting the speed of a sound based on gameplay elements can be achieved by manipulating the pitch of the sound.

Could you please try adding a parameter [FMOD Studios|7. Parameters|7.1 Uses of Parameters](https://www.fmod.com/docs/2.00/studio/parameters.html#uses-of-parameters) to your event, typically something like “Speed”, which should ideally receive values from your game that correspond to your character’s movement speed. [Unity Integration|10. Scripting API Reference | StudioEventEmitter|StudioEventEmitter::SetParameter](https://www.fmod.com/docs/2.02/unity/api-studioeventemitter.html#studioeventemitter_setparameter). Then automate the pitch property of the sound and tweak the automation curve to define how pitch changes with your “Speed” parameter. For example, a lower pitch at lower speeds and a higher pitch at higher speeds.

Alternatively, using Rigidbody you could use our built-in speed parameter: [FMOD Studio|22. Parameters Reference|22.3.7 Speed (Relative)](https://fmod.com/docs/2.02/studio/parameters-reference.html#speed-relative). This will take care of passing the speed of the rigidbody to the parameter for you.

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