Suppose we have the following room layout, where we have rooms A, B, C, and D, separated between them with doors. [2021-09-30 19.02.19] Let’s assume I have emitters on every room and they are assigned to a separate bus for every room. The listener is able to move between rooms, and I’m able to kno…

Indeed, that seems tricky to implement within fmod studio, though that would only take a few lines of code… I think the best idea is to beg the developer to implement the logic in the game code :smiley:

I just had an idea, though. Use multiple sends between busses, to mimic the real geography. Send some A in B and some B in A, and so on for each pair of consecutive rooms. Automate those sends with snapshots related to door state: if A/B door is closed, less A goes into B (and conversely). In top of…

Steam Audio might be the answer for this kind of thing if you’re using Unity. Sadly no support for Steam Audio with FMOD if you’re using Unreal. I built a custom audio propagation solution in Unreal using A* pathfinding and special rules of propagation through portals and rooms, which is a fancy wa…

Thanks @Alcibiade @ptrefall ! This gave me some ideas. Maybe in the future I could use Steam Audio, but for now, I ended up implementing the door logic in a scripting language that sits between my backend and the parameters I receive, so now for each “inside_space” snapshot, I get several parameter …

This is what I was thinking to answer. We implemented this in one game and it went very well. Cheers!

I managed in the past this situation in a lecture on FMOD + Unity without using occlusion I used: a single label parameter describing in which room the player is a mixer bus (group) for every room to route all the 3d ambience emitters placed in that room emitter placed behind every door (this me…

Thank you @Gianni , that’s exactly what I ended up doing. Works good enough for now
