The decoder class decodes a sound field in the harmonics domain through the planewaves domain.
The decoder should be used to decode a set the harmonics domain to a set of planewaves for loudspeakers. There are three types of decoder. Regular for a perfect circle or sphere of loudspeakers. Irregular when the loudspeakers are not equally spaced on the circle or the sphere. Binaural for headphone restitution.

inline |
The decoder constructor.
The decoder constructor allocates and initialize the base classes.
| order | The order |
| numberOfPlanewaves | The number of channels. |

This method retrieves the mode of the decoder.
This method retrieves the mode of the decoder.

pure virtual |
This method performs the decoding.
You should use this method for in-place or not-in-place processing and sample by sample. The inputs array contains the spherical harmonics samples and the minimum size must be the number of harmonics and the outputs array contains the channels samples and the minimum size must be the number of channels.
| inputs | The input array that contains the samples of the harmonics. |
| outputs | The output array that contains samples destinated to the channels. |
Reimplemented from Processor< D, T >.
Implemented in DecoderBinaural< Hoa3d, T >.
|
pure virtual |
This method computes the decoding matrix.
You should use this method after changing the position of the loudspeakers.
| vectorsize | The vector size for binaural decoding. |
Implemented in DecoderBinaural< Hoa3d, T >.
