1. A method of coding a sound signal as various streams of frames, in which the sound signal is subdivided into various segments and each segment is coded to a corresponding frame, characterized in that the sound signal is represented as a set of sine waves defined by their amplitude and frequency, in that the amplitude and the frequency of each sine wave in a segment are stored in a frame corresponding to this segment, independently of other segments, and in that the frames thus obtained are numbered and subdivided into n streams, where frame number i is subdivided into stream i modulo-n.
