Extension
ExtensionFirst Order Ambisonic (FOA) directivity transformer
Source: ATK.sc
Description
Adjust the soundfield directivity of a First Order Ambisonic signal (B-format) along the y-axis.
Class Methods
FoaDirectY.ar(in, angle, mul: 1, add: 0)
From superclass: FoaDirectX
Arguments:
| in |
The B-format signal, an array: [w, x, y, z] |
| angle |
The distortion angle, in radians. 0 to pi/2 |
| mul |
Output will be multiplied by this value. |
| add |
This value will be added to the output. |
Discussion:
Angle = 0 retains the current directivity of the soundfield. Increasing angle towards pi/2 decreases the directivity along the y-axis, reducing the gain on this axis to zero, and is equivalent to a spatial low-pass filter. The resulting image becomes directionless on the y-axis.
