Abstract (en)

[origin: WO2006097633A1] The invention concerns a method and a system for spatializing an audio signal (SS), which consists in: subdividing (A) the audio signal into successive frames (TSS<SUB>i</SUB>), analyzing (B) the frames by frame blocks to determine at least one spectral and/or physiological parameter (P<SUB>spj</SUB>) in each frame, allocating (C) to each frame an index (j,k) representing said parameter to generate a sequence of classified frames and subjecting (D) each frame (F) attributed a common index (j,k), to a spatializing processing (S<SUB>j,k</SUB>). The invention is useful for spatializing monophonic, stereophonic, speech, telephone signals and the like.
