I have a 2D scroller game and have added an FMOD Studio Event Emitter to the finish line, which I want the player to hear when they get close enough to it. However, it is audible throughout the entire map. How do I make it so that it will start fading in from a certain point and be fully audible once you hit the end?

Hi,

Have you added a [Spatializer effect](https://fmod.com/docs/2.02/studio/glossary.html#spatializer-effect) to the sound? This will attenuate the signal based on the event emitter’s position relative to the listener.

Hope this helps!

Hi Connor, I have a Spatializer on the master track in FMOD Studio. I also have a FMOD Listener on the main camera in Unity.

Thanks for the info,

What version of the FMOD integration are you using?

Could I get a screenshot of the [Emitter](https://fmod.com/docs/2.02/unity/game-components.html#studio-event-emitter) in your Unity project? It could be having the [Min & Max](https://fmod.com/docs/2.02/studio/glossary.html#spatializer-effect:~:text=The%20min%20%26%20max,distance%20override%20drawer) values set on the spatializer effect. You should be able to see a white sphere around the emitter in the Unity scene, could you check that it isn’t larger than you expected?

The outer circle is the `max` value and the inner the `min`.

Hope this helps!
