| titleOfInvention | Spatial synthesis of multichannel audio signals |
| abstract | The invention pertains to a method of spatial synthesis of a sum signal so as to obtain at least two output signals, the sum signal as well as the spatialization parameters being output from a parametric coding by matrixing of an original multi-channel signal. The method comprises the steps of: - decorrelation (Decorr.) of the sum signal (s) to obtain a decorrelated signal (d); - application (synth.) of a synthesis matrix (M Minq) whose coefficients depend on the spatialization parameters (R, I), to the decorrelated signal and to the sum signal so as to obtain said output signals, and is such that for at least one range of value of at least one spatialization parameter, the coefficients of the synthesis matrix are determined according to a criterion of minimizing a quantitative function (q), relating to the quantity of decorrelated signal in each of the output signals obtained by the step of applying the synthesis matrix. The invention also applies to a synthesis device, to a decoder comprising at least one synthesis device and to a multimedia apparatus comprising such a decoder. |
