Extension
ExtensionFirst Order Ambisonic (FOA) asymmetry transformer
Source: ATK.sc
Description
Apply asymmetry to a First Order Ambisonic signal (B-format).
Class Methods
FoaAsymmetry.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.
