First Order Ambisonic (FOA) dominance transformer

Description

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

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

Class Methods

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

From superclass: FoaDominateX

Arguments:

in

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

gain

Dominance gain, in dB.

mul

Output will be multiplied by this value.

add

This value will be added to the output.

Discussion:

Positive values of gain increase the gain at [pi/2, 0] to +gain dB, while decreasing the gain at [-pi/2, 0] to -gain. This simultaneously results in a distortion of the image towards [pi/2, 0]. Negative values of gain invert this distortion, distorting towards [-pi/2, 0] . The default, 0, results in no change.
