- Abstract:In this paper, a scalable audio compressing scheme is presented, which is mainly based on an Embedded Zerotree Wavelet (EZW) coding technology. Firstly, 29 critical subbands are obtained by splitting audio signals with a Digital Wavelet Package Transform (DWPT). Then, a Zerotree coding is acted on these subbands. Lastly, an entropy coding is applied to remove redundancy and a specific frame structure is formed. The resulting encoder can support a scalable bit stream from 16kbps to 64kbps with a 4kbps step size for a single audio channel and the graceful degeneration of subjective audio quality can also be provided.
