Patent ID: 8488824

Claim:
A method for sequencing spectral components associated with respective spectral bands of elements to be encoded originating from an audio scene comprising N signals, with N>1, said method comprising: calculating a respective influence of at least some of the spectral components which can be calculated as a function of spectral parameters originating from at least some of the N signals, on mask-to-noise ratios determined over the spectral bands as a function of an encoding of said at least some of the spectral components; and allocating an order of priority to at least one spectral component as a function of the influence calculated for said at least one spectral component compared to the influences calculated for other spectral components, the influence of a given component being calculated by estimating a variation between: a first mask to noise ratio determined as a function of a coding of said at least some of the spectral components according to a first rate, and a second mask to noise ratio determined as a function of a coding of said at least some of the spectral components from which said given component is deleted according to a second rate lower than the first rate.
