Extension
ExtensionFirst Order Ambisonic (FOA) press transformer
Description
Apply press to a First Order Ambisonic signal (B-format) along the z-axis.
Class Methods
.ar
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:
Press is a dominance related transform, specified in terms of a distortion angle. Positive values of angle press the image towards [0, pi/2]. Negative values press towards [0, -pi/2]. The default, 0, results in no change.
