mdf no sound issue
Jean Marc & list,
Following up on this- there seems to be an issue with this calculation
in mdf.c (Smooth echo energy estimate over time)
Pey += Eh*Yh;
Pyy += Yh*Yh;
it goes too large for floating point, which seems to be caused by extremely
large values in st->Rf[j], st->Yf[j] and smaller values in st->Eh[j],
st->Yh[j]-
things were relatively quiet environmentally speaking.
Anyhow, leak_estimate would then go to...

Re: speex echo cancellation limitations
...for your prompt and helpful reply.
In FLOAT_DIVU() it hangs at the following:
while (a.m >= b.m)
{
e++;
a.m >>= 1;
}
for the case where a and b are both zero (yes, division by zero).
This happens from mdf.c:
leak_estimate = FLOAT_EXTRACT16(FLOAT_SHL(FLOAT_DIVU(st->Pey, st->Pyy),14));
where st->Pey and st->Pyy are both zero, which happens for the following input
data to testecho program:
-- first arg is file containing sine wave of magnitude +/- 32767
-- 2nd arg is file containing all zeroes
The division by zero appears to be caused by the calculation:...

True, that needs to be fixed even after I fix the rest.

Load Sharing PPP Connections on an Masqed LAN
Hi, can anyone help me with this problem i''ve got!
I have a problem with routing on my Mandrake 7.2 Linux Box i was wondering if you could help me with. I live
in Australia and as broadband access isn''t very available at the moment, i have 2 modems to dialup to my isp
(dynamic ips assigned) to increase my bandwidth at an affordable level. What currently happens is i have a
