First Order Ambisonic (FOA) zoom transformer
Source: ATK.sc

Description

Apply zoom to a First Order Ambisonic signal (B-format) along an arbitrary axis.

NOTE: FoaZoom is usually called via the convenience wrapper FoaTransform.

Class Methods

FoaZoom.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 zoom along the axis defined by theta and phi. See FoaZoomX.

NOTE: Corresponding matrix transformer: FoaXformerMatrix: *newZoom
