Abstract

In this paper, a new digital audio compression system based on the modified transform and dynamic bit allocations is introduced. The modified transformation is proposed for the time-frequency representations of signals and the dynamic bit allocations scheme is used to progressively quantize the transform coefficients according to the rate distortion theory. Computer simulation results show that this proposed system, which achieves high audio quality on the rate 4 bits per sample, possesses low computational complexity suitable for multimedia applications. This coding system can further be operated in case of variable bit rate to allow application specific ancillary data without drastic loss of signal quality.
