TitleA Design of Lossless Compression for High Quality Audio Signals
AbstractThree extension tools for extending and enhancing the compression performance of prediction-based lossless audio coding are proposed. The first extension aims at supporting floatingpoint data input in addition to integer PCM data. The second is progressive-order prediction of the starting samples at each random-access frame, where the information on previous frame is not available. The third is inter-channel joint coding. Both predictive coefficients and prediction-error signals are efficiently coded making use of the inter-channel correlation. These new prediction tools will contribute to enhance the for the coming MPEG-4 Audio Lossless Coding (ALS) scheme, currently being under development as an extension of the ISO/IEC MPEG-4 audio standard
