Dolby Atmos is an object-based spatial sound engine, which means it plays sounds based on the virtual locations that they should come from in relation the person hearing the sounds. Roblox already tracks where sounds come from based on their relative positions to the camera and then decides how these sounds are played out in Stereo, so the basic framework appears to be already in place.
This means that, in theory, it’s feasible to implement Dolby Atmos using existing code.
This is just a thought. I lack access to official Roblox source code
