<div dir="ltr"><font face="tahoma" size="2">I have now investigated further why the leak_estimate increases when near end is talking for a longer</font></div>
<div dir="ltr"><font face="tahoma" size="2">time. What happens is that the accumulated crosscorrelation of y (Pyy) in mdf.c is decreasing towards</font></div>
<div dir="ltr"><font face="tahoma" size="2">zero. The leak_estimate is calculated as the divistion of Pee with Pyy and when Pyy is close to zero</font></div>
<div dir="ltr"><font face="tahoma" size="2">the output will dramaticily increase.</font></div>

<div dir="ltr"><font face="tahoma" size="2">At least in my application there is need of handeling this behaviour. Have anyone else seen this behaviour</font></div>
<div dir="ltr"><font face="tahoma" size="2"><font face="tahoma">in your application</font>?</font></div>
<div dir="ltr"><font face="tahoma" size="2"></font> </div>
<div dir="ltr"><font face="tahoma" size="2">One idea I have is to add a </font><font face="tahoma" size="2">constant or floor to Pyy in the divisoin. Does anyone have any other ideas?</font></div>
