Hi I have a question about the AEC and preprocessor. I have seen that when near end is talking for a longer time (about 10 s) without being interrupted by the far end the residual echo (or rather leak_estimate) increases making the preprocessor suppress the near end talk when it shouldn't. Is there a way to make the leakage estimate only update when far-end is present or similar in order to

...ltinomial logit models (without using surrogate Poisson models) -or even better- nested multinomial logit models? I am using the Windows version of R (Windows 95). To my understanding, the S package called nnet does that, but it seems not to work in R. Thanking in advance for any help, Marjo Pyy-Martikainen Government Institute for Economic Research P.O.

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 undefined, which would...

...mpt 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: See = inner...
