Audio coding with low delay that alternates predictive coding and transform coding

摘要

Method of coding a digital audio signal, including the steps of: - encoding (E601) of a previous frame of samples of the digital signal according to a predictive coding, - encoding (E603) of a current frame of signal samples digital according transform coding; process characterized in that a first part of the current frame is encoded (E602) by a predictive coding restricted regarding the predictive coding of the previous frame reusing at least one parameter of the predictive coding of the previous frame and encoding only parameters not reused this first part of the current frame
