Abstract
The RVLC which is an EBCOT-based coding method has been utilized successfully recently in image compression as in JPEG 2000. In this paper we propose a new and efficient audio compression based on EBCOT and RVLC. Firstly the original audio signal is decomposed with a lifting wavelet packet transform, then RVLC and Huffman methods are used to process the coefficients of low and high subbands respectively. The psychoacoustic model and probability model are also taken into account to achieve high quality of reconstructed audio signal. The results of our experiments show that the method is efficient.
