Generating a frame of audio data

A data carrying medium carrying a computer program that when executed by a computer, carries out a method of generating a frame of audio data for an audio signal from preceding audio data for the audio signal that precede the frame of audio data, the method comprising the steps of:

• predicting a predetermined number of data samples for the frame of audio data based on the preceding audio data, to form predicted data samples, each predicted data sample being a linear combination of a predetermined number of audio data samples immediately preceding the frame;
• identifying a section of the preceding audio data for use in generating the frame of audio data;
• and
• forming the audio data of the frame of audio data as a repetition of at least part of the identified section to span the frame of audio data, wherein the beginning of the frame of audio data comprises a combination of a subset of the repetition of the at least part of the identified section and the predicted data samples.
