Class Methods

.ar

Arguments:

in

The B-format signal, an array: [w, x, y, z]

angle

theta

Azimuth, in radians.

phi

Elevation, in radians.

mul

Output will be multiplied by this value.

add

This value will be added to the output.

Discussion:

Applies focus along the axis defined by theta and phi. See FoaFocusX.
