First Order Ambisonic (FOA) rotation transformer

Description

Rotate a first order ambisonic signal (B-format) around the x-axis.

The inbuilt equivalent is Rotate2.

Class Methods

*ar (in, angle: 0, mul: 1, add: 0)

From superclass: FoaRotate

Arguments:

in

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

angle

Rotation angle, in radians.

mul

Output will be multiplied by this value.

add

This value will be added to the output.

Discussion:

A rotation of pi/2 will rotate a source at [pi/2, 0] to [0, pi/2].

NOTE: Corresponding matrix transformer: FoaXformerMatrix: *newTilt
