Higher Order Ambisonic (HOA) zoom transformer

Source: HoaUGen.sc

Apply zoom to a Higher Order Ambisonic signal (HOA) along an arbitrary axis & radius.

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. |

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.
