First Order Ambisonic (FOA) push transformer

Description

Apply push to a First Order Ambisonic signal (B-format) along the y-axis.

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

Class Methods

.ar

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:

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

NOTE: Corresponding matrix transformer: FoaXformerMatrix: *newPushY
