GENERATING A FRAME OF AUDIO DATA

摘要

A method of generating a frame (302e) of audio data for an audio signal from preceding audio data (302a-d) for the audio signal that precede the frame (302e) of audio data, the method comprising the steps of: predicting (S500) a predetermined number of data samples for the frame (302e) of audio data based on the preceding audio data (302a-d), to form predicted data samples (600); identifying (S502) a section of the preceding audio data (302a-d) for use in generating the frame (302e) of audio data; and forming (S504, S506) the audio data of the frame (302e) of audio data as a repetition (602) of at least part of the identified section to span the frame (302e) of audio data, wherein the beginning of the frame (302e) of audio data comprises a combination of a subset of the repetition (602) of the at least part of the identified section and the predicted data samples (600).
