Abstract (en)
[origin: WO2012172264A1] The present invention relates to a method for processing an original audio signal of N.x channels, N being greater than 1 and x being greater than or equal to 0, comprising a step of multichannel processing of said audio input signal by a multichannel convolution with a predefined imprint, said imprint being formulated by the capture of a reference sound by a set of enclosures disposed in a reference space characterized in that it comprises an additional step of selecting at least one imprint from among a plurality of imprints previously formulated in different sound contexts.
