Hi,List.<br><br>I am studying the TCH AMR codec; <br><br>I using the first 8 bits of any TCH frame block to decide whether it is a speech frame or a signal;<br><br><span lang="en"><span>Although it will</span> <span>contain</span> <span>some non-</span><span>speech frame; but I think it can capture all the speech frame and <br>

<br>the captured file can be decoded correctly. is that right?<br></span></span><br><br>
