Spatializer for mobile FPS game

Hey! We are on an FPS mobile game project. We liked the FMOD Spatializer. However, we want to check the alternatives for our game. Oculus and Steam Audio spatializer doesn’t support iOS build and Resonance audio sounds so muffled even when the source and listener are in the same spot.
Any other suggestions?

There is the FMOD Object Spatializer which should work on all your required platforms.

An alternative is to create your own spatializer using the built-in parameters to dictate what happens when an event instance is at a certain distance, orientation, or elevation. This will require more setup, but you could create Default events to help with setting up each spatialized event.
