FoaMirror
Extension
ExtensionFirst Order Ambisonic (FOA) mirror transformer
Description
Mirror a First Order Ambisonic signal (B-format) across an arbitrary plane.
Class Methods
.ar
Arguments:
| in |
The B-format signal, an array: [w, x, y, z] |
| theta |
Azimuth for the normal to the plane, in radians. |
| phi |
Elevation for the normal to the plane, in radians. |
| mul |
Output will be multiplied by this value. |
| add |
This value will be added to the output. |
Discussion:
Mirroring across the origin and individual axes is implemented via FoaXformerMatrix: *newMirrorO and FoaXformerMatrix: *newMirrorX, FoaXformerMatrix: *newMirrorY, FoaXformerMatrix: *newMirrorZ.
NOTE: Corresponding matrix transformer: FoaXformerMatrix: *newMirror
