HoaAsymmetry
Extension
ExtensionHigher Order Ambisonic (HOA) asymmetry transformer
Description
Apply asymmetry to a Higher Order Ambisonic signal (HOA).
Class Methods
.ar
Arguments:
| in |
The input signal. |
| angle |
Distortion angle, in radians. -pi/2 to pi/2 |
| radius |
Radius, in meters. |
| order |
Ambisonic order. |
Discussion:
Positive values of angle rotate [-pi/2, 0] towards [0, 0], and at pi/2 collapse the soundfield to a travelling wave. Negative values rotate [pi/2, 0] towards [0, 0]. The default, 0, results in no change.
Imaging is illustrated here.
