Yes.

That's correct. Vorbis

Why is libvorbis so big ?
I've been looking at the organisation of my project trying to trim down it's
size a touch... and libvorbis, is really the only think bigger than 100k
coming in at over 1 meg .dll
I've been looking through the code for vorbis_enc as that's the object file
taking 95% of the space, and i can't figure out why it is so damn big...
there's only a few thousand lines of code there

Sizing down Ogg Vorbis encoder binaries
Not too long ago, I converted my whole cd library to
OGG format, because I loved the way it sounded, and
the fact that is was open source. Recently, I wanted
to update my library with the latest CVS code. I just
did a compile of the CVS ogg binaries (ogg.dll,
vorbis.dll, vorbis_enc.dll, vorbis_file.dll), and I
noticed they were alot larger in size than the
default ones that came with CDex. I

yet another stereo related question
Hi!
>From http://www.vorbis.com/stereo.psp : "Oggenc's default choice varies
by bitrate and each mode is selectable by the user"
So, how am I supposed to do that? E.g. what do I have to do when I want
an 128kbps .OGG using lossless stereo, or does this "selectable by the
user" mean only that I can choose the stereo mode indirectly by choosing
an appropriate bitrate?

Dom0 cpu utilisation irregularly distributed
On some production servers with dom0 kernel 2.6.32 pvops and xen 4.0 and
domus mainly windows with gplpv I noticed a strange cpu usage by the dom0
mainly with the use of a single cpu, for example this take from one server:
xm vcpu-list
Name ID VCPU CPU State Time(s) CPU
Affinity
...

[PATCH][RFC] OpenUPS driver
Hi all,
I attached a driver for MiniBox openUPS device (
http://www.mini-box.com/OpenUPS) and a dump of the hid usages.
I had the possibility to make a few adjustments to the device firmware for
HID usages, and although I haven't managed to produce a good structure
many issues from previous firmware were at least fixed and new information
added.
ATM the driver only shows pertaining

Big into winbindd ? 100% of cpu after 5mn of utilisation

anyone know if they have a big bug to winbindd ? :

Cpu Utilisation
what metric is used to calculate cpu-utilisation, the command xe host-cpu
-param-get param-name=utilisation, returns a negative number, returns nan,
why this occurs?

Why Point-Stereo at 160 kbps ?
Hi there !
I checked Vorbis' performace for mono files at
approx. 64-80 kbps (it does a good job) and I'm
wondering why the current OggEnc still uses
Point-Stereo (>10kHz) for -q4 and -q5
I know, we're usually unable to percieve those
phase correlations above 10 kHz, But a
Dolby Prologic Decoder isn't.
I think a future version of OggEnc which is able
to use a user-selectable

Is it possible to record 2-4 party call audio in stereo quality as opposed to mono?
We have a customer who wants us to record anywhere from 2-4 participants on a call in stereo (as opposed to mono) quality audio.
Some background..
We are using asterisk 16.6.1
We are also currently using AMI/AsyncAGI and ConfBridge to bring the parties together. I believe recording in the various file formats (based on extension), it's always recording in mono quality.
My one thought is to

Samba 3.0.25b: smbd 99% CPU utilisation with opened MS Word doc
Hi I'm trying to upgrade from Samba 3.0.23c on FC4 to 3.0.25b from Samba
sources.
Everything appears to function correctly until an MS word document is
opened from a share - the file opens but the smbd process in question
rockets to 99%+ CPU, stays there & needs kill -9'ing to stop it. This
happens reliably.
I have an appropriate strace & a level 7 log but can't see anything

100% CPU utilisation
Dovecot (0.9.11) consumes 100% CPU utilisation when accessing
(either pop or imap) one of my mailboxes. It doesn''t happen
with other mailboxes.
The mailbox has about 500 mails while others have many more.
They are all in mbox format.
OS: OpenBSD-3.5 with all patches
MTA: Sendmail-8.12.11
It happened with other RCs of dovecot-0.9.11

Sox and bad quality when converting to 8 kHz
Hi list,
I have an 44100 Hz file with human voice, stereo with 16Bit.
When convertig this to 8 kHz, mono I loose a lot of quality and have
some ground noise. I tried several sox options but without success.
Can somebody help....

Quality & ripping speed
Thanks for all the great responses on tools to use - I have Exact Audio Copy
and CDex working very well, and I've been working out all the kinks.
Two questions, one very Vorbis related, one not :)
1) I know people have asked many times "What quality should I use". Well, I
want to ask it again but in a narrower frame. I see less than 10% difference
in size between 4.99 and 5.00 -

streaming to dialup users gives low quality audio
Hello,
I've got two streams, one for broadband, one for dialup. Well, having
had occation to use a dialup connection recently i checked the dialup
stream. Although it was streaming what the broadband stream was, the audio
quality was audibly worse. It didn't buffer, but it didn't sound as clear as
the broadband stream. I used lame to encode the tracks to mp3 and used it's

Archival quality for music
This mail depends upon the fact that I don't have a couple of good
earphones ;-)
I read in the site that q=6 is a very high quality, but does it contain
perceivable differencies from the original? (for 95% of people, of course).
I also found q=6 to produce files slightly bigger (1/10 bigger) than those
produced with lame VBR q=2 (about 192 bps on average). I always thought

Monitor and sox mix quality
Hello All,
I am using monitor with soxmix, however the quality seems somewhat low
after sox converts to mp3.
Does anyone know a way to get a higher quality file? Some of my lines
