AB  - Most lossless audio-coding algorithms are designed for PCM input sound formats. Little work has been done on the lossless compression of IEEE floating-point audio files. An efficient lossless-coding algorithm that handles IEEE floating-point format data as well as PCM format data is described in this paper. In the worst-case scenario, where the algorithm was applied to artificially generated 48-kHz sampling frequency and 32-bit floating-point sound files, an average compression ratio of 65% was still achieved for sound files with 48kHz sampling frequency. Moreover, the proposed algorithm is easily extensible to lossless/variable-lossy operation, which will provide scalability to accommodate the requirements of a wider range of applications and platforms.
