Some Speex AGC Questions
I'm attempting to use speex preprocess for automatic gain control in an
application I'm working on and could use some help.
I'm using Opus as my codec. In order to keep the number of packets down,
I'm using 60msec frames. I'm sampling at 48KHz as is recommended for Opus.
So, the frame length is 2880 samples and the sampling rate is 48000. The
source of the data is a

mingw (native gcc for win32) doesn't officially support using gcc 4.0
and 4.1 yet (apparantly there have been some issues), so there are no
binary packages. But if you think it helps, I can compile gcc 4.1 and
give it a shot.

Question about SPEEX_PREPROCESS_SET_DENOISE
Unlivable.
I fix it. I forgot the speex_preprocess(m_pPreprocess, buf, NULL) need to do
enough samples too.
Tks a lot!
And
speex_preprocess_ctl(preprocess, SPEEX_PREPROCESS_SET_DEREVERB,
&tmp);

speex_preprocess_ctl(preprocess,
SPEEX_PREPROCESS_SET_DEREVERB_DECAY, &f);

Preprocessor denoise. Does it work?
I'm having trouble with the preprocessor's noise reduction feature.
The basic issue is that it simply doesn't work very well.
With my laptop (whose microphone is otherwise quite capable) I
routinely hear transient background noise, typing, and other "quiet"
sounds leaking through to the speex stream. Even worse, the AGC
feature is blowing these things up into just awful

Unable to start Asterisk 1.4 on CentOS 4.4 (installed from ATrpms)
Hi Everyone,
I am still unable to start Asterisk 1.4 that I installed using ATrpms.
I was initially suspecting some permissions issues but it seems to me
that its more to do with a speex codec not loading properly.
Here is the message I get if I run asterisk -cvvvvvvvvvvvvvv
app_userevent.so => (Custom User Event Application)

Reverberation cancellation
Hi,
I'm trying to use Speex Echo Canceller for mobile device. The AEC works well
so far.
However, I want to know how to remove reverberation significantly. I noticed
it's not implemented yet in Speex AEC. Are you going to implement it in next
version? Could you provide some ideas how to handle reverberation on current
version?
Thanks in advance.
Sincerely,
Dennis

1.6.2.6: can't upgrade from 1.6.1.18
I'm running 1.6.1.18 on an older ubuntu machine. I upgraded to
dahi-linux-2.3.0. That went fine, and it works. But I decided to use the
opportunity to upgrade to 1.6.2.6. That didn't work.
configure, make menuselect, make, make install all went fine, or at
least seemed to. But it hangs starting up here:

Audio Speed Variability
I have a video conference like application that I've been working on for
a while now, and a recent change is causing some odd problems, and I was
wondering if anyone else had seen problems like this. The issue I'm
seeing is that when using the sound card for capture, the audio will
eventually get about 1-2 seconds out of synch (delayed), from the
video. However, if I use USB devices

What is the relation of CELT and SPEEX?
Hi Jean-Marc,
I got to this mailing list while trying to use the latest SPEEX version
(1.2rc1) VAD capabilities.
I had difficulties to successfully distinguish speech from non speech on
recorded files (probably doing something wrong).
Digging into the code I found out a remark saying :"*The VAD has been
replaced by a hack pending a complete rewrite*".
In search for answer I found out

xen 3.3.0 + intrepid domU (2.6.27-7-server) + >4gb ram problem
Hi,
we''re using Xen 3.3.0 on Debian Etch with 2.6.18.8 kernel from xen.org
on dom0. We have problems starting Intrepid domU (using Intrepid''s
kernel 2.6.27-7-server) if we give more than 4GB of memory to this domain.
Using memory = ''4096'' works perfectly, but changing it to ''4097'' already
gives an error. Can anyone put some light on this?

change pxe filename/prefix
Hello,
is it possible to overwrite 'filename' dhcp options with pxelinux
command line arguments? I think it would be very useful when building
complex netboot menus. If not are you planning to add it in near future?
greetings

Set off high-pass filter
Dear Sir/Madam,
I am PhD student in Speech Enhancement at INRIA in France. I am part of the
Multispeech team, which is supervised by Emmanuel Vincent. My work includes
echo cancellation, dereverberation and noise suppression. It's been 2 years
I am using SpeexDSP for echo cancellation.
I noticed there was a high-pass filter and I tried to deactivate it by

Speex VAD&denoise algorithms on TMS320C6713
Hello,
I'm almost beginner in DSPs and need advise. I did some simple applications on TMS, but now it's time for something bigger:).
I'd like to implement VAD & denoise algortihms on TMS320C6713 in real-time, one channel.
Can I use part of Speex for it? Is Speex sufficiently efficient? I try Speex on PC and it works very good.
Any advise will be helpful.

howto forbid chown on cifs mount
Hello list,
I'm trying to get around old samba-users problem with common share used
by many people. What I would like to achieve is to get all files in that
share to belong to specific group.
I was already trying the 'chmod g+s' way, but its not what I'm looking
for, as this sets specific group only for newly created files and still
gives possibility to change it later on (and it
