Transceiver only has 32 channels, so it seems like transceiver won’t be enough. What would be a good alternative way to position the reflected signals?

The issue may be we are trying to call 3D commands on a 2D sound. This is further explained here: FMOD API | White Papers - 3D Sounds . You will need to add the FMOD_3D flag to the [image] chrane: FMOD_MODE mode = FMOD_OPENUSER | FMOD_LOOP_NORMAL; that is currently used to create the sound. F…

Hi, Could you elaborate on what you are trying to achieve?

@Connor_FMOD Something similar to wwise reflect, say Calculate some reflection points for active events. Create “virtual emitters” at the reflection points that plays the same signal as the source event. Apply the delay, attenuation change, filters to the virtual emitters. (Either defined by curve…

Hi, Unfortunately, FMOD does not natively support reflections. However, the Resonance Audio ( Fundamental Concepts - Early Reflections and Reverb ) plugin does have early reflections which we do support ( FMOD Studio | Advanced Topics - Resonance Audio ) and is included with FMOD Studio. [image] I wo…

Thanks for the pointers! We are developing using Unreal. I’m completely open to write our own DSP, or calculate the reflection points ourselves. The part I’m not sure how to do is duplicating and repositioning signals(beyond the 32 channels limit). Is there any way you would recommend doing this? I…

The Resonance Audio simulates reflections using Raycasts to all the room surfaces (or simply in 6 directions). Then for each surface found use the distance to the collision to calculate the delay which will be added to a buffer. Playing the sound back panned towards the collision with the delay and …

Connor you are the champion, gonna do some experiment this weekend!

I’m doing some quick’n dirty prototyping ine UE, got some sounds playing on the fly following the user_created_sound example. I was testing if I can pipe those sounds to an FMOD panner, but for some reason, I don’t hear any panning changes: Code below: // Called when the game starts or when spawne…

Bump see if I can get some help debugging the code above :eyes: I’m not sure why generating sound buffer-> pipe into a panner approach wouldn’t work, feel like there’s a bug in the code.

Hi, You were super close, try changing these values: absolute.position = { 0,1,0 }; // to absolute.position = { 50,50,0 }; Hope that helps!
