| Abstract: | In this paper,whole coding scheme of lossless audio compression based on orthogonal transform is presented,and the key technologies such as framing, integer transform and entropy coding are introduced in detail. Experimental results show that the transform based scheme provides lower bit rates than those of linear prediction based schemes. |
| Keywords: | lossless audio compression integer transform IntMDCT entropy coding |
