 Extension
ExtensionApply dominance to a first order ambisonic signal (B-format) along the x-axis.
| 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. | 
Positive values of gain increase the gain at [0, 0] to +gain dB, while decreasing the gain at [pi, 0] to -gain. This simultaneously results in a distortion of the image towards [0, 0]. Negative values of gain invert this distortion, distorting towards [pi, 0] . The default, 0, results in no change.
