Abstract
The invention relates to a method for ordering spectral parameters of ambisonic components to be encoded (A, . . . , A) originating from an audio scene comprising N signals (Si=), in which N>1, comprising the following steps: calculation of the respective influence of at least some spectral parameters, taken from a set of spectral parameters to be ordered, on an angle vector defined as a function of energy and velocity vectors associated with Gerzon's criteria and calculated as a function of a reverse ambisonic transformation in relation to said quantified ambisonic components; and allocation of a precedence order to at least one spectral parameter as a function of the influence calculated for said spectral parameter compared to the other calculated influences.
