Fwd: Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
An update:
I found that the "ADD32: output is not int:" messages are caused by the enhancer. When I turn the enhancer off, the messages vanish, but the "freak out" of the codec is still there - so the problem seems not to be related to the overflow messages.
best regards,
Frank

Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
Hi Jean-Marc, all,
I didn't get any response to my issue up to now and would like to now if anyone can reproduce this behaviour and if there is some idea what happens. I am willing to fix this issue, but because I do not know the internals of speex, I need some advice on how to proceed...
best regards,
Frank

Hi Jean-Marc,
I did what you proposed. I changed the levinson durbin algorithm to:
{
int i, j;
spx_word16_t r;
spx_word16_t error = ac[0];
for (i = 0; i < p; i++)
lpc[i] = 0;
if (ac[0] == 0)
{
//for (i = 0; i < p; i++)
// lpc[i] = 0;
return 0;
}
for (i = 0; i < p; i++) {
/* Sum up this iteration's reflection coefficient

Hi Frank,
Sorry, I *do* care about the problem and just happen to be overworked at
the moment. What I suspect is that the pitch gain gets close enough to
unity that the loss makes it bust. Did you test with the floating-point
code?

Fwd: Re: Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
What happens if you change that line:
if (cumul_gain > 262144)
to use a smaller value? What value works OK (if any)?
One more thing, when things go wrong, do they eventually go back to
normal or does the codec never recover? It's unavoidable that the audio
goes bad for a short period of time because of the long-term predictor.

Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
Hi,
I'm quite sure we found a bug inside the codec (1.2rc1, wideband mode). It only
occurs when speex is compiled with the FIXED_POINT flag.
I feed in a 2000 Hz sine wave (-15 dBFS). When I simulate a single frame loss
(i.e. pass a null pointer to speex_decode_int as second parameter for just one frame), the decoder
starts to freak out a second later: It produces horrible noise with 0 dBFS.

Fwd: Re: Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
Hi Jean-Marc,
yes, problem exists in narrowband-mode, too.
I already twiddled with max_gain, but did not have real success. I changed line 337 of ltp.c (function pitch_gain_search_3tap_vq)
if (sum>best_sum && gain_sum<=max_gain) {
to
if (sum>best_sum && gain_sum<max_gain) {
-- that stabilizes speex for 2000 Hz and 2200 Hz input on quality setting 7 (23800

Hi Jean-Marc,
I'm currently trying to analyze the LPC synthesis filter. For this, can you please tell me the exact format of the LPC coeffs (in variable interp_qlpc), please?
cheers,

FREAK/Logjam, and SSL protocols to use
List, good afternoon,
I was reading up on a TLS Diffie Hellman protocol weakness described here
https://weakdh.org/sysadmin.html
which is similar to the earlier FREAK attack, and can result in
downgrade of cipher suites.
Part of the solution workaround that the researchers describe for
Dovecot here

includes altering DH parameters length to 2048, and

Fwd: Re: Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
O.k., some more info:
I just tested bandwidth widening to fix this. But I need to go to gamma values below 0.9 to become stable -- clearly too much widening, I think.
I looked inside the Levinson-Durbin algorithm next. The lines
#ifdef FIXED_POINT
r = DIV32_16(rr+PSHR32(error,1),ADD16(error,8));
#else
r = rr/(error+.003*ac[0]);
#endif
look interesting. While for floating point,

Can zaptel freak out if you configure 2 trunks but use only one?
I am using Asterisk 1.2.13 with Zaptel 1.2.11, I used to have an old PBX
connected to one port and the PRI connected to the other.
I'm having serious stability issues with Asterisk on a box that has been
rock solid previously.
The old PBX died two months ago so one port on the TE210P is now unused
but still configured. Also I'm afraid I have upgraded from Asterisk
1.2.9.1 and the old

New FREAK SSL Attack CVE-2015-0204
Hello,
about the CVE-2015-0204, in apache the following config seems to disable
this vulnerability:
SSLProtocol All -SSLv2 -SSLv3
SSLCipherSuite
HIGH:MEDIUM:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4
Is something similar possible with dovecot ?
If yes, what are the implications with old mail clients ?
