Abstract (en)
[origin: WO2008145893A2] The invention relates to a method for ordering spectral components of elements to be encoded (A1,..., AQ) originating from an audio scene comprising N signals (Sii=1 to N), in which N>1, an element to be encoded comprising spectral components associated with respective spectral bands. The invention is characterised in that it comprises the following steps: calculation of the respective influence of at least some spectral components that can be calculated as a function of the spectral parameters from at least some of the N signals on the mask-to-noise ratios determined over the spectral bands as a function of the encoding of said spectral components; and allocation of a precedence order to at least one spectral component as a function of the influence calculated for said spectral component compared to the other calculated influences.
