Abstract
An audio signal (X) is represented by a bitstream (B) segmented into frames. An audio processing system () comprises a buffer () and a decoding section (). The buffer joins sets of audio data (D; D, . . . , D) carried by N respective frames (F, F, . . . , F) into one decodable set of audio data (D) corresponding to a first frame rate and to a first number of samples of the audio signal per frame. The frames have a second frame rate corresponding to a second number of samples of the audio signal per frame. The first number of samples is N times the second number of samples. The decoding section decodes the decodable set of audio data into a segment of the audio signal by at least employing signal synthesis, based on the decodable set of audio data, with a stride corresponding to the first number of samples of the audio signal.
