Bitrate problem
This is a common problem. Sound cards run at different
clock speeds (but your difference seems kinda high).
What I'd suggest is dropping silence packets once in a
while.

Bitrate problem
Thanks all for your prompt reply.
I agree with Alex. I think jitter buffer will have to
drop packets if its input bitrate is higher than it is
configured for.
I never tried speex jitter buffer. What does it do
when input bitrate is higher or lower ?
As an alternate solution, I was thinking to play with
directsound playrate [using SetFrequency()]. Has
anyone used it to solve such problem?

Help needed for echo cancellation
Hello all,
I use speex as codec [narrowband and wideband], echo canceller and preprocessor. I was able to use it in all case except in echo cancellation.
I found that in my application, echo cancellation works only if echo tail [echo filter length] is arround 2000 ms or more. But recomended value in the documentation is 100 ms. With 2000 ms echo tail echo cancellation works fine but it takes

Bitrate problem
Hello all,
This is a bit off topic but I am sure many of you can
answer it.
I use speex and speex-wb in my VOIP application. With
speex [at 8 KHz] bitrate is arround 30KBPS, including
UDP,RTP headers. This is OK for me and I get good
quality audio.
Problem is, if call is made from a HIGH END machine
[like P4 3.2 GHz with good soundcard] to a LOW END
machine [like P3 550 MHz], high end pc sends

Help needed regarding AGC
Hello All,
I use AGC as one of speex preprocess options in VOIP application. In most cases it works very fine.
However, at the very beginning of a call when no one has started talking [ and some times in the middle of calls], AGC makes large noise and it gradually increases. Interestingly, when someone starts talking, from that point it works very well.
Is it the normal behaviour? Since

Who is using the jitter buffer?
Oh, I forgot to mention one thing. I currently append a few bits of custom
information to each speex packet which I fetch out with
things like
speex_bits_unpack_unsigned(&sjJitter.current_packet, 1);
It would be very usefull if the jitter buffer didn't actually decode the
packet, but instead returned a pointer to it (or NULL if you should play
silence and -1 if you should repeat the

Public Folder ACL Problem
Hi All,
I am trying to achieve ACL set in Public folders, I have public namespace in

}
and now under public folder I have two subfolders .test and .test1 . I have
created dovecote-acl under .test so that it can be seen and subscribe.

multiple t-tests across similar variable names
Hi everyone-
I have a dataset with multiple "pre" and "post" variables I want to compare. The variables are named "apple_pre" or "pre_banana" with the corresponding post variables named "apple_post" or "post_banana". The variables are in no particular order.

Syslinux 4.10-pre20
I think I finally have nailed down the problems with TFTP on the 4.10
branch, and so I have released 4.10-pre20.
Please let me know if you have hardware on which 4.05/4.06-pre3 works,
and 4.10-pre20 does not.

Dove LDA vs Exim LDA
Hello All,
I have built up my email server with exim + dovecot + clamv/spamassasin.
I am using exim as LDA(local delivery agent). I was reading about using
dovecot as LDA but I couldn't find why should I use it?
Now, I am looking expert advice on "Why should I use dovecot LDA" ? Is
there any benefit in terms of functionality or performance ?

Syslinux 5.11-pre7 not working
Hi,
I am a happy user of version 4.06 and have been hoping to upgrade the 5.x series (for the HTTP bits).
I have the following problems with the 5.11-pre7 build:
1. TFTP load is horribly slow ... even when the two REAL machines are connected to the same switch.
For a typical RHEL installation, the vmlinuz loads ... the initrd.img loads very very slowly and just times out (I waited over 10 mins)

Voice Activation Level (speex 1.1.11.1)
Alex,
It's purely empirical, but I've found that values in the range
of 0.001 to 0.002 tend to offer a nice tradeoff between rejecting
unwanted sounds and picking up all legitimate speech. I use a
default of 0.0015 in my program and it seems to work well. For
bounds of the GUI slider, I use 0.00005 and 0.01.
Sorry, but I don't know how these values translate to dB or any
other
