This is a small extension to the earlier article on Pro Tools Pan Laws. The Dolby Atmos panner has different modes for handling the elevation.

The various modes available are:

Free Mode

The Z Axis is free and independently controlled.

Wedge Mode

This gives the room a peaked ceiling like a Pyramid with the Apex Parallel to the screen. The Z axis is derived from the formula: Z = 100-abs(Y)

Sphere Mode

This gives the room a dome ceiling with the Middle of the room having Max Elevation and reducing to the sides. The Z axis here is derived from the formula:

Z = √[ 100² – {min (100²,(X² +Y²))} ]

Ceiling Mode

The Z axis here is a Curve from front 40% of the Room to the Screen and Flat on the ceiling for the remaining 60%.
