Hi FMOD Team! I’m starting to seriously try understanding the profiling system and ensure we’re preserving proper performances in our game. I realized this morning that I had a bunch of events that are triggering a huge amount of simultaneous active voices. I’m not sure I understand the reason. I…

[image] _MaX: Is it like FMOD trying to playback the voices during virtualization and immediately stopping them since the event is actually virtualized? Yes, that is essentially what is happening. [image] _MaX: Does this mean we should account for this super short active voices as normal…

The FMOD Studio Max Instances setting controls voice stealing in relation to event instances. This can be viewed by selecting the Instances graph option. The Voices graph however is actually displaying the number of underlying Channels that your instruments are controlling. The reason you are seeing…

Hi Jeff! Thank you for your feedback. I indeed had a good grasp of the virtualization vs non-virtualized events. That said, your answer is making me question myself about that actual understanding :stuck_out_tongue: So a couple of other questions: To better understand the processes behind, what…

I’d like to know this too as in my recent tests with over 500 virtualized voices i got mandatory problems with sound not playing at all, especially gameplay related sounds. But reducing these to around 70 without a change in active voices count all problems were gone.

The Total Channel Count in the FMDO for Unreal integration defaults to 512. This means that if you are already playing 512 voices, the 513th voice will do one of two things: Steal from another playing voice, that has the lowest audibility Not play at all if there are no voices with a lower audibi…

I should check out the project settings more often. [grafik] I feel so dumb. Thanks for clarification. Haha

Hi Jeff, Thank you very much for your answers. I wanted to give a bit of feedback on our choices so that the thread helps other people in the future. We’ve opted for a fast distance computation between the blueprints/assets and the player(s), instead of using triggers which are not ideal ( physic…
