arecord pipe to celtenc just stops
Hi all,
Just found out about this codec and I'm really impressed.
I compiled celt-0.5.2.tar.gz on my desktop and tried out a few tests. I
then did a native fixed point arm compile on my beagleboard which also
worked a treat.
Before I get started with the library I was trying to see if I could
grab some real time audio, encode it and write to a file using arecord
in conjunction with

listening experiment
Hi All,
I was wondering whether there have been some listening experiments done
to test how well spatial information is preserved in the celt signal,
e.g. comparison of sound localization performance for the original
uncompressed sound and the celt sound (most probably for different bit
rates).
Best, Pablo

celtenc/celtdec does not display CELT_VERSION
A small issue, but missing.
Something like this would be helpful:
- printf ("celtenc (CELT encoder)\n");
+ printf ("celtenc (CELT %s encoder)\n", CELT_VERSION);

celtclient 64kbps more than expected
Hi,
The default settings for celtclient are:-
Sampling rate 48000
Frame size 256
Packet size 43
According to my calculations this should give a bitrate of 64kbit/sec +
a little extra for the 32bit time stamp and 4 null byte pseudo header.
Using vnstat I was very surprised to see that it was reporting a bitrate
usage of around 16kbyte/sec which is 128kbit/sec, double what I was
expecting.

celtenc 0.11.1 not generating encoded file on OSX Lion
Hi,
I am running celt 0.11.1 on my mac which is running osx lion. I invoke
celt such as so:
celtenc original.wav output.oga
I do not see any files being encoded, the wave file is stereo 16 bit at
44.1kHz.
Any ideas on why this is not working? I also tried the opus git repo for
the latest sources, but that also does not produce an encoded file.
Thanks

Introduction + Patch
Hi,
I'm new here so an introduction. I'm Stefan de Konink, I have a diverse
past, present and future in coding, content creation and a background in
speech research. As introduced on #celt I want to do some promotion for
the codec.
I was positively surprised by the availability of something 'almost
done' and totally usable in the form of celtclient.c, attached is a tiny

Celtenc not working in 0.9.1
Hi,
I'm currently testing libcelt (celt-0.9.1) on my Openwrt/Kamikaze
RDC-3210 platform and although I'm able to Crosscompile on my Ubuntu
10.10 machine without errors, the resulting celtenc doesn't seem to work
properly.
Ran ./configure via the Openwrt makefile first (activating fixed-point) ;
I first produce a S16_LE Raw PCM file (48Khz, stereo) : test.pcm

Foreign SID's and winbind use default domain
-----BEGIN PGP SIGNED MESSAGE-----

Hi
In the Samba HOWTO (ch. 24 section 24.3.2) is written
"When winbind is used, the default condition is
that the local user george will be treated as the account DOMAIN\george
and the foreign (non-member of the domain) account will be treated as
MACHINE\george because each has a different SID."

Advice on parsing formulae
Dear list
I would like to be able to group terms in a formula using a function that I
will call tvar(), eg. the formula
Y ~ 1 + tvar(x:A) + tvar(z) + u + tvar(B) + tvar(poly(v,3))
where x,u and v are numeric and A and B are factors - binary, say.
As output, I want the model.matrix as if tvar had not been there at all. In
addition, I would like to have information on the grouping, as a vector

trouble building celt on Fedora
Hi All,
I'm looking to package up celt for inclusion in Fedora as the next
stable release of ekiga/opal will have support for it. I've run into
two issues in compiling it into a rpm. The first is a show stopper,
then second one not so much of an issue but thought I'd report it for
reference.
The first issue is due to the celtdec and celtenc explicitly define
rpath. I get the

Winbindd and idletimeout on the LDAP server

We have a problem with samba (winbind) when we enable idletimeout on the
OpenLDAP servers. If it is set we sometimes get an error:

HSM devices and FreeBSD
I am essentially asking the same question that Eirik Overby asked a
couple of years ago. Is anyone aware of PCI-X/PCIe hardware security
modules that are supported on FreeBSD? I have not seen any on the
FreeBSD hardware compatibility lists. Again, as Eirik noted in his
question, HSMs are not simply crypto accelerators (which are supported
on FreeBSD), they also are a means of storing keys

Dual mono not stereo
Hi,
If I want to encode two audio channels that are not related, audio from
two different sources not stereo, is it best to create two instances of
a single channel encoder or use one encoder with two channels?
thank you,

right settings for highest quality
Hi
I am trying to evaluate the quality of the CELT codec by using the 0.8.0
testcelt tool to encode and decode the input.
I want to test different bitrates and selected the below parameters for 64,

Bad artifacts at 32kbps
I have been trying some different sample rate and bitrate combinations
to get a feel for how CELT behaves.
I then encoded it with a couple of different frame sizes and sample
rates. There were some small differences, but nothing horrible.
So, I decided to run with 24KHz sample rate with 16 bit samples. This
seemed like a reasonable tradeoff against the quality degradation that

bit error robustness
Hello everyone,
I'm evaluating the Celt in terms of robustness against bit errors.
So what I have done is encoding a wav file using the \tools\celtenc.exe
and then manipulated the wav file according a desired bit error rate or
burst error length.
But the Celt decoder stops decoding with the first bit I manipulated even
if this bit is not in the header.
So is there a way to do the test
