| Abstract: | The amount of data is incredible large after audio signal is digitized. It is not convenient for transmission and storage. Digital audio coding has became one of the key techniques in digital technique which is more and more widely applied today. This paper describes most audio coding methods, and analyses some of the important audio coding algorithms. |
