Hi guys,

Thanks a lot for the answers! I guess, unfortunately, I was right and there’s no way to override the distance calculation between listeners and sounds. Too bad, but I guess this is a pretty niche problem, so I get why that’s the case.

Regarding 3d level, I guess I have to do a bit more testing - based on [this](https://qa.fmod.com/t/lowering-3d-panning-effect-in-channels/13203/5) thread and what I’ve seen, setting a 3d level of anything \< 1 disables 3d attenuation, at least with inverse rolloff. I’m in the process of trying out using a custom rolloff for this, to see if it’ll sort this problem out.

Regarding using another listener, that’s a really clever idea, and one that I didn’t think of, but I’m not sure it’ll work. According to the [docs](https://fmod.com/resources/documentation-api?version=2.0&page=core-api-system.html#system_set3dnumlisteners), “If the number of listeners is set to more than 1, then panning and doppler are turned off.”

I’m currently reading through the DSP callback stuff to see if I can figure out a way to do everything with that, but I don’t know if it’s actually an appropriate solution to either of my problems.
