This invention concerns a process for processing at least one coded-binary audio flux organized into frames created from digital audio signals which were coded by subjecting them first to a transform from the time domain into the frequency domain in order to calculate transform coefficients then to a quantification and coding stage of the said transform coefficients according to a set of quantifiers, the said set being determined from a set of values extracted from the said signals, values that make up selection parameters of the said set of quantifiers, the said parameters also being present in the said frames. It is characterized in that it includes a partial decoding stage consisting of decoding then dequantifying the transform coefficients produced by the coding based on a set of quantifiers determined from the said selection parameters contained in the said frames of the coded binary audio flux or of each coded binary audio flux, and subjecting the said partially decoded frames to the said processing in the frequency domain, then making the frames thus processed available for use in a later utilisation step.
