Abstract :
Recently, with the advance of network and storage technologies, it is becoming realistic that people will enjoy high sampling rate, high resolution audio contents with lossless quality. Envisioning of such a need, the international standardization body MPEG has recently introduced a scalable tool for lossless audio coding, namely, MPEG-4 Audio Scalable to Lossless (SLS) coding. MPEG-4 SLS integrates the functionalities of lossless audio coding, perceptual audio coding, and fine granular scalable audio coding in a single framework; meanwhile it provides backward compatibility to MPEG-4 Advanced Audio Coding (AAC) at the bit-stream level. This new tool, in combination with the existing MPEG audio toolset, provides a universal digital audio format that can be used in a variety of application domains such as professional audio, Internet music, consumer electronics, broadcasting
