Extension
ExtensionFirst Order Ambisonic (FOA) focus transformer
Inherits from: Object
Description
Apply focus to a first order ambisonic signal (B-format) along an arbitrary axis.
Class Methods
*ar (in, angle: 0, theta: 0, phi: 0, mul: 1, add: 0)
Arguments:
| in |
The B-format signal, an array: [w, x, y, z] |
| angle |
The distortion angle, in radians. -pi/2 to pi/2 |
| theta |
Azimuth, in radians. |
| phi |
Elevation, in radians. |
| mul |
Output will be multiplied by this value. |
| add |
This value will be added to the output. |
Discussion:
Applies focus along the axis defined by theta and phi. See FoaFocusX.
