First Order Ambisonic (FOA) directivity transformer

Subclasses: FoaDirectY, FoaDirectZ

Adjust the soundfield directivity of a first order ambisonic signal (B-format) along the x-axis.

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

angle |
The distortion angle, in radians. 0 to pi/2 |

mul |
Output will be multiplied by this value. |

add |
This value will be added to the output. |

**Angle** = 0 retains the current directivity of the soundfield. Increasing **angle** towards pi/2 decreases the directivity along the x-axis, reducing the gain on this axis to zero, and is equivalent to a spatial low-pass filter. The resulting image becomes directionless on the x-axis.

NOTE: Corresponding matrix transformer: FoaXformerMatrix: *newDirectX

Please see various examples here.
