A lossless audio compression software for Windows application

This paper focuses on the design of an adaptive lossless compression algorithm for audio waveforms, which aims to be used in Internet, PC game, library archive applications, etc. Windows based software is developed which can also be used in DOS or UNIX operating system. The lossless compression is based on the Rice code (Rice and Plant, 1971), and a scheme to adaptively select a best set of Rice code parameters to enhance the compression ratio is proposed. In order to obtain a higher compression ratio, an adaptive linear predictor is employed. Our software achieved a slightly higher compression ratio than a known commercial Windows based package and is compatible with another more efficient DOS based package
