Methods for encoding an audio signal and to decode a stream of audio, audio codec audio player, the audio system, audio stream, and storage medium.Coding of an audio signal (x) is represented by a set of values of respective signal sampled for each of a plurality of segments sequ00b3enciais is exposed.The values of the sampled signal are analyzed (130) to generate one or more components sinusoidal (F ~ K ~ F ~ k - 1 ~,) for each of the plurality of segments sequ00b3enciais.Sinusoidal codes (CS) including trails connected sine components (F ~ K ~ F ~ k - 1 ~,) are generated (13) and update information of phase ( sym ~ K ~, 30 ~ K ~) indicative of the value of phase of sinusoidal components selected on a track is determined.An audio stream encoded (the so-called) including sinusoidal codes (CS) and the update information of the phase ( sym ~ K ~, ~ ~ k 30) is then generated (15).
