The ambisonic encoder.
The encoder should be used to encode a signal in the spherical harmonics domain depending of an order of decomposition. It allows to control the azimuth of the encoding.
| Hoa2D::Encoder::Encoder | ( | unsigned int | order | ) |
The encoder constructor.
The encoder constructor allocates and initialize the member values to computes spherical harmonics coefficients depending of a decomposition order. The order must be at least 1.
| order | The order. |

This method performs the encoding with single precision.
You should use this method for in-place or not-in-place processing and performs the encoding sample by sample. The outputs array contains the spherical harmonics samples and the minimum size must be the number of harmonics.
| input | The input sample. |
| outputs | The output array.Get the azimuth angle The method returns the last angle of encoding between 0 and 2π. |

| void Hoa2D::Encoder::setAzimuth | ( | const double | azimuth | ) |
This method set the angle of azimuth.
The angle of azimuth in radian and you should prefer to use it between 0 and 2 Pi to avoid recursive wrapping of the value. The direction of rotation is counterclockwise. The 0 radian is Pi/2 phase shifted relative to a mathematical representation of a circle, then the 0 radian is at the "front" of the soundfield.
| azimuth | The azimuth. |
