Abstract (en)
[origin: WO0162044A1] The invention concerns a method for comparing data characterising reference values and data characterising current values of sound-reproducing systems in a system of (n) microphones mi and (p) speakers hpj to control said sound-reproducing systems. The method comprises steps which consist in: (A) for each speaker hpj, sending at least a sound signal S over the speaker hpj; recovering for each microphone mi an information recorded hpjmi characterising the sound-reproducing system including the speaker hpj and the microphone mi; (B) saving a reference matrix Qr consisting of the set of reference data hpjmi obtained in response to sending the sound signal S; (C) when it is desired to establish a comparison, executing step A with a sound signal S' to obtain current data from a matrix Q; (D) comparing matrices Q and Qr.
