HoaZoom
Extension
ExtensionHigher Order Ambisonic (HOA) zoom transformer
Description
Apply zoom to a Higher Order Ambisonic signal (HOA) along an arbitrary axis & radius.
Class Methods
.ar
Arguments:
| in |
The input signal. |
| angle |
Distortion angle, in radians. -pi/2 to pi/2 |
| theta |
Azimuth, in radians. |
| phi |
Elevation, in radians. |
| radius |
Radius, in meters. |
| order |
Ambisonic order. |
Discussion:
Applies zoom along the axis defined by theta and phi at radius.
Zoom is a normailised dominance variant, specified in terms of a distortion angle. Positive values of angle increase gain at [theta, phi], while reducing at [theta.neg, phi.neg]. Negative values do the inverse. The default, 0, results in no change.
Imaging is illustrated here.
