FoaRTT
ExtensionExtension

First Order Ambisonic (FOA) multi-axes rotation transformer

Description

Rotate a First Order Ambisonic signal (B-format) around the z, x and y axes.

The inbuilt equivalent is Rotate2.

NOTE: FoaRTT is usually called via the convenience wrapper FoaTransform.

Class Methods

.ar

Arguments:

in

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

rotAngle

Rotation angle around z-axis, in radians.

tilAngle

Rotation angle around x-axis, in radians.

tumAngle

Rotation angle around y-axis, in radians.

mul

Output will be multiplied by this value.

add

This value will be added to the output.

Discussion:

Rotate is followed by tilt and then tumble.

NOTE: Corresponding matrix transformer: FoaXformerMatrix: *newRTT
