1. Function

The 6DF Multiplexing (CAE-6DX) multiplexes each plane wave component, p ∈[1,P] at each time frequency bin (k, n) including its amplitude, A, and direction index, h, on a spherical grid and the output of the 6DF Compression..

Receives	Dominant Plane Wave
	Compressed Diffuse Field
	Device Scene Geometry
Produces	Audio Object (6DF)
