Apply dominance to a first order ambisonic signal (B-format) along the z-axis.
The B-format signal, an array: [w, x, y, z]
Dominance gain, in dB.
Output will be multiplied by this value.
This value will be added to the output.
Positive values of gain increase the gain at
[0, pi/2] to +gain dB, while decreasing the gain at
[0, -pi/2] to -gain. This simultaneously results in a distortion of the image towards
[0, pi/2]. Negative values of gain invert this distortion, distorting towards
[0, -pi/2] . The default, 0, results in no change.
Please see various examples here.
