The binaural decoder class decodes a sound field in the harmonics domain for headphones.
The binaural decoder should be used to decode an ambisonic sound field for headphones. It decodes the sound field through the planewaves domain an convolves the results with HRTF from the IRCAM database.
Definition at line 192 of file Hoa_Decoder.hpp.
| DecoderBinaural | ( | const size_t | order | ) |
The binaural decoder constructor.
The binaural decoder constructor allocates and initialize the member values to the decoding matrix depending on a order of decomposition and a number of channels. The order and the number of channels must be at least 1.
| order | The order |
|
pure virtual |
The binaural decoder destructor.
The binaural decoder destructor free the memory.
|
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. |
Implements Decoder< Hoa2d, T >.
|
virtual |
This method performs the binaural decoding.
You should use this method for not-in-place processing and performs the binaural decoding sample by sample. The inputs array contains the spherical harmonics samples : inputs[number of harmonics] and the outputs array contains the headphones samples : outputs[2].
| inputs | The input samples. |
| outputs | The output array that contains samples destinated to channels. |
Implements Decoder< Hoa2d, T >.
