How does FMOD mixdown from any surround format (including 7.1.4) to stereo if the platform is not using a surround format? I read in the forums that you did away with SRS. What is the new method? And is there any officially sanctioned way to monitor how the mixdown will sound from within FMOD Studio…

The way that FMOD handles the downmix for any surround format to stereo is by using a mix matrix, although at this point we do not have this available in our docs, in the case of 7.1.4 the height speakers just get removed leaving 7.1. In FMOD 2.00.00, the special case of 5.1 to stereo that used SRS…

What dB values does the mix matrix use for the downmixes? I assume C is the standard -3dB, but what does the mix matrix do to the surround channels and LFE in 5.1 and 7.1 → stereo? It seems that the documentation has not yet been clarified with this. I would need this info urgently as I’m just upmi…

Same problem here, get worse if console monitoring is needed: For example, I set Switch to 7.1 as system preferences (that should be the max number of channels in the best case scenario, that is Switch is connected via dock to a 7.1 system). Using “auto” as format in the master output in the mixer…

I could be wrong but I think Switch only supports up to 5.1, which isn’t a big deal if you’re also releasing for other platforms that support higher. But if you’re only releasing on Switch, at least your mixdown would be less involved if you mix in 5.1. Have you tried Cameron’s solution yet? Monito…

Bringing back this topic. I would very gladly like to know too how the internal matrix works, there is just no way to know at the moment. Thank you
