How do you handle BINAURAL vs STEREO mixing with options for switching?

we want to include a game option for letting the player choose his audio setup.

a) stereo 2.0 desktop speakers

b) headphones

My question is how to mix our sounds in the first place. Creating two seperate output mixers or handling it an other way? Thos is not a question on downmixing I believe, but more how to switch oon/off “binaural”. Can this be scripted?

Anyone with experience ??

Typically, there are two ways to switch between speaker modes in FMOD.

The first is to create multiple different platforms in FMOD Studio (for example, “Desktop (5.1 speakers)” and “Desktop (Headphones)”) as described in the Setting Up Different Audio Configurations for Your Game section of our documentation. This allows you to create different versions of your banks for the different autio output devices your game supports, and switch between them by loading and unloading the relevant banks.

The second way is to build your game only for one speaker channel format (typically one with a high speaker channel count), use sends to send the signal to different return buses in the mixer that downmix the signal to different speaker channel formats, and use snapshots or send automation to adjust which of those return buses is audible at runtime.
