FoaPressX

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

NOTE: FoaPressX 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, 0]. Negative values press towards [pi, 0]. The default, 0, results in no change.
