Title
A design of lossy and lossless scalable audio coding
Abstract
This paper proposes a lossless audio coding scheme making use of high-compression lossy coding such as the ISO/IEC MPEG-4 audio standard. The encoding process consists of lossy compression, bit slice lossless data conversion, and lossless coding. The lossy compression significantly reduces the amplitude of the error signal between the input signal and the reconstructed signal. In addition, bit slice data conversion makes the lossless coding more efficient. As a result of preliminary experiment, a total file size can be reduced to 70-50% of the original size, which is significantly more efficient than conventional universal lossless coding schemes such as "gzip". The resultant compressed data is useful for various applications, since it has bit rate scalability and can be used as a highly compressed signal as well as a lossless signal.
