SuperCollider CLASSES (extension)

FoaPressZ

First Order Ambisonic (FOA) press transformer
Source: /usr/local/share/SuperCollider/Extensions/SC3plugins/ATK/Classes/ATK.sc

Description

Apply press to a first order ambisonic signal (B-format) along the z-axis.

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

Class Methods

*ar (in, angle: 0, mul: 1, add: 0)

From superclass: FoaRotate

Arguments:

in

The B-format signal, an array: [w, x, y, z]

angle

The distortion angle, in radians. -pi/2 to pi/2

mul

Output will be multiplied by this value.

add

This value will be added to the output.

Discussion:

Press is a dominance related transform, specified in terms of a distortion angle. Positive values of angle press the image towards [0, pi/2]. Negative values press towards [0, -pi/2]. The default, 0, results in no change.

NOTE: Corresponding matrix transformer: FoaXformerMatrix: *newPressZ
