摘要

The invention relates to a method for encoding a source audio signal. According to the invention, such a method comprises the following steps: coding of a quantization profile of coefficients representative of at least one transform of the source audio signal, according to at least two distinct coding techniques, delivering at least two sets of data representative of a quantization profile; - selection of one of the data sets representative of a quantization profile, based on a predetermined selection criterion; - transmission and / or storage of the representative data set d a quantization profile selected and an indicator representative of the corresponding coding technique.
