A novel prediction scheme for lossless compression of audio waveform

Abstract

For compression of audio waveform, prediction is one of the important key components. We propose a novel multi-stage adaptive linear predictor (MSALP) for the prediction of high fidelity audio waveform. The MSALP achieves higher prediction gain compared with conventional linear predictor (LP). Besides, the MSALP uses less number of coefficients. The MSALP is embedded into a lossless audio waveform compression system. As a result, the system compression ratio is obviously improved. By selecting known lossless audio waveform compression algorithms, some comparison results are presented.
