In this paper , i mainly developed the theory of open - source ogg vorbis audio technique including its coding and decoding procedure . the theory was introduced in sections according to different functional modules 我在本論文的研究過程中,對oggvorbis算法的編解碼原理進行了深入的研究,將其按照不同的模塊分別進行分析。
In this paper , we mainly develop the theory of melp , including the procedure of coding and decoding . in that time , we also have done the work of simulating analysis . in the end we research the method of completing this arithmetic of c programming language . in chapter one we briefly introduce the developing status of the technology of voice coding and decoding , the method of appraising the performance of voice coding and the structure of this paper . chapter two shows the general situation and the new five characters of melp . we introduce the coding procedure in chapter three and four and the decoding procedure in chapter five . chapter six shows the details of programming 本論文第一章簡要敘述了語音編解碼技術發(fā)展狀況、評價語音編碼性能的方法和本文的組織結構;第二章簡要介紹了melp語音壓縮編碼算法的概況和melp算法新增的五大特點;第三章和第四章詳細介紹了melp算法的編碼過程;第五章詳細介紹了melp算法的解碼過程;第六章對melp算法的c語言實現方法作了介紹。
