ABSTRACT:
A method and apparatus for compression and decompression of an audio signal. In encoding an input audio signal, at least a portion of the audio signal is transformed into a set of coefficients. A set of binary vectors associated with the set of coefficients are generated for digitizing the transformed audio signal using a fixed rate adaptive quantization. Information based on the set of binary vectors is combinatorially encoded and output as a bit stream of encoded audio data. The encoded audio data may be stored, transmitted, and/or decoded.
