yep I look into the mixmonitor and finally track to function ast_slinear_saturated_add which actually<br>mix the read and write audio. But I confuse on its implementation for it just simply add the read audio<br>with write audio. The audio data is encoded so I think it should not directly add with it and it should <br>
first decode audio data as PCM then add.<br><br><div class="gmail_quote">On Fri, Sep 10, 2010 at 8:13 PM, Russell Bryant <span dir="ltr"><<a href="mailto:russell@digium.com">russell@digium.com</a>></span> wrote:<br>

</div></div>Is there a question in here somewhere? If you're interested in how to use audiohooks to mix both the read and write audio paths, see the MixMonitor() implementation.<br>
