Description Most of G.729 source code is written in C.But this one is written in matlab. follow these steps to use it: 1.To coder a speech(ensure it as a row vector variable in matlab),simply type "G729code(speech)",then you will see a file called coding.bit in your directory. 2.To decoder the codestream.bit,first,copy the file codestream.bit to your G.729decoder directory,you simply type "main",and it will decoder the above file coding.bit to a speech in your matlab(syn_speech).
