Extension
ExtensionFirst Order Ambisonic (FOA) dominance transformer
Description
Apply dominance 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] |
| gain |
Dominance gain, in dB. |
| mul |
Output will be multiplied by this value. |
| add |
This value will be added to the output. |
Discussion:
Positive values of gain increase the gain at [0, pi/2] to +gain dB, while decreasing the gain at [0, -pi/2] to -gain. This simultaneously results in a distortion of the image towards [0, pi/2]. Negative values of gain invert this distortion, distorting towards [0, -pi/2] . The default, 0, results in no change.
