FoaAsymmetry
ExtensionExtension

First Order Ambisonic (FOA) asymmetry transformer

Description

Apply asymmetry to a first order ambisonic signal (B-format).

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

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

The distortion angle, in radians. -pi/2 to pi/2

mul

Output will be multiplied by this value.

add

This value will be added to the output.

Discussion:

Positive values of angle rotate [0, -pi/2] towards [0, 0], and at pi/2 collapse the soundfield to a planewave. Negative values rotate [0, pi/2] towards [0, 0]. The default, 0, results in no change.
