Abstract
A signal processing method transforms X input signals into M output signals. The method includes applying a decorrelation filter to the X input signals so as to generate N decorrelated signals e; and for each decorrelated signal edetermined, generating N delayed signals eby applying a delay τand a gain gto each decorrelated signal e, the delays τand the gains gbeing chosen. For each decorrelated signal e, the delayed signals esimulate a propagation of the decorrelated signal in a virtual space. The virtual space has N virtual loudspeakers and a virtual listening position that are distributed according to a predetermined geometry. For each value of k, summing the delayed signals e: E=Σe; and determining M output signals, each output signal resulting from a linear combination of the N sums of the delayed signals E.
