Abstract: In this thesis, we developed a codec, which using the adaptive linear prediction for lossless audio coding. We successfully designed a cascade structure with independently adapting FIR filter in each stage for the multistage adaptive linear predictor, which outperforms other techniques, such as linear prediction coding (LPC) used in the state-of-the-art lossless audio codec. Meanwhile, the detailed theory analysis is given out for the cascade structure and adaptive linear prediction. Moreover, we also provide random access feature in the codec while the performance is still guaranteed, although the performance is much decreased by supporting random access due to the transient phase in adaptive linear prediction. With the successful application of adaptive linear prediction, by now our codec outperforms most of the state-of-the-art lossless audio codecs for most digital audio signals with different resolutions and different sampling rates.
