How can I control output levels of various surround channels?

0 votes
I have a game mixed in 7.1, 5.1 and Stereo. I like the mix as is, but the two side channels in the 7.1 mix are both too hot (too much gain). Is there a way to attenuate just those two channels? Is there a divergance setting or some other way to accomplish this? If I go back to my panning, it changes the 5.1 balance which I am happy with at the moment.

Unfortunately, there is no easy way to do this from the Authoring tool, you will need a programmer to implement it for you.

The easiest way would be to register the Bus Volume callback (see https://www.audiokinetic.com/library/2015.1.2_5457/?source=SDK&id=namespace_a_k_1_1_sound_engine_a48a069a39cd20d04fbbd8782df3ee386.html#a48a069a39cd20d04fbbd8782df3ee386 ). This will give you access to the matrix of channel volumes for a bus. Inside that callback, you can then modify this matrix to attenuate your side channels, using the AkSpeakerVolumeMatrixCallbackInfo (see https://www.audiokinetic.com/library/2015.1.2_5457/?source=SDK&id=struct_ak_speaker_volume_matrix_callback_info.html)

Well, that is what my programmer is for! This is awesome, now that I know this I can get it sorted out. Thanks for the info Benoit!
