Jean Marc & list,<br><br>
Following up on this- there seems to be an issue with this
calculation<br>
in mdf.c (<font face="Arial, Helvetica" color="#008000">Smooth echo
energy estimate over time)<br><br>
</font><font face="Arial, Helvetica">
Pey += Eh*Yh;<br>
Pyy += Yh*Yh;<br><br>
</font>it goes too large for floating point, which seems to be caused by
extremely<br>
large values in <font face="Arial, Helvetica">st->Rf[j], st->Yf[j]
and smaller values in st->Eh[j], st->Yh[j]-<br>
</font>things were relatively quiet environmentally speaking.<br><br>
Anyhow, leak_estimate would then go to undefined, which would mess
up<br>
<font face="Arial, Helvetica">r, which would mess up power_1[], which
would then mess up some <br>
things in weighted_spectral_mul_conj, etc.<br><br>
</font>There may be other issues but this is the one that makes the<br>
most sense as to causing the silence issue- for now, I just put a <br>
finite check on leak_estimate and that seems to prevent the symptom,<br>
but doesn't fix it.<br><br>
Maybe in this case Eh and Yh just need to be
re-calculated/re-set?<br><br>
