Psychoacoustic model
We've implemented a vorbis decoder based on Tremor and as part of the
documentation we're also writing about psycho acoustic models and
encoding.
We're quite up to date with the decoding process and psycho acoustics
in general but unfortunately not on the psycho acoustic encoding used
in Vorbis.
We have a few questions that would we would be very thankful to have

A new introduction attempt.
I have been using libvorbis for the past few weeks and have been asked to
summarise what I have discovered about the codec. There is an early draft
of the document at
http://www.geocities.com/gatewaystation/vorbis/vorbis.htm - Please forgive
the dodgy formatting (it was formerly a MS word document that got converted
with their 'save as html' feature). I still have some additions to

Multithreading
Hi.
I need to execute a function from within a GUI.
This seems to be no problem but this function takes about 4 minutes to
finish, which means the application doesn't react at all, while the
function is running.
Can I execute a function as a separate Thread, while keeping
control(e.g. a reference) of it at the same time?
If not, how do this with a class containing this function?
thanks,

broken link in documentation
hello,
i'm reading the doc at http://xiph.org/ogg/vorbis/doc/Vorbis_I_spec.html
and the link to the paper
http://www.iocon.com/resource/docs/ps/eusipco_corrected.ps
doesn't work.
Could anyone correct the link and/or mirror this paper ?
Thanks,

I've made a vorbis encoder in delphi, but it's very verey slow!
It takes 5 minutes to encode a pcm file.
And i don't know why. Could anyone help me???

ogg multithread encoding
Hello!
I'm working on a program which purpose is to compress a single wav file using many processes. I know that my solution may not look excellent but in my opinion it's simple to implement it in a program.
What I've managed to do is:
-split single wav file into many parts (with appropriate headers),
-create process for each part,
-each process executes 'oggenc' program.

Problems with ov_open continued
I've downloaded the latest versions of the libraries available from the
website, http://www.vorbis.com/download_unix.psp, and compiled them, but
it hasn't made any difference to the situation.
I downloaded the .tar.gz "for everyone" versions, not the rpm developer
versions. Will this make any difference?
Cheers,
Oliver Sneyd

For Oggvorbis algorithm description.
Dear Sir,
I am a DSP Engineer working in the field of Audio Standards
and general Signal Processing Algorithms. I am very much interested in
knowing the algorithms which make OggVorbis a reality. Kindly send me
the link which will lead me to the algorithm description or pseudo-code.
Thanking You,
Sincerely,
Tom Xavier.

Using large-scale repetition in audio compression
This idea is so simple that I'm sure it must have been thought of
before, and discarded, since AFAIK it's not used anywhere. I did a
quick web search but that didn't turn up much, so I figured I'd put
it up for discussion here anyway.
How about using large-scale repetition in audio compression? I'm
thinking of redundancy in repeated pieces of a song, ie a chorus.

AW: AW: Reading OGG embedded in a pack file
yes, you are right. i always search for quick and easy solution and
forget in the meantime that vorbis is a low level codec library. so
probably a wrapper lib is the right way. but as far as i understand
vorbisfile is already a bunch of convenience functions? so to speak a
wrapper lib ? so why not enhance a little bit vorbisfile ?
and - i did not felt personally attacked. i just wanted to note

Problems building vorbis tools 1.0.1
hi!
I've got some problems compiling/linking the vorbis tools.
at first I had the same problem as mentioned here:
http://www.xiph.org/archives/vorbis-dev/200201/0005.html
(make was looking for libogg.la in the wrong path)
but creating a symlink to /usr/local/lib/libogg.la in /usr/lib/ helped. :)
having solved this, I get a new error:

A different take at video encoding - I'm stuck though
As I said in the other thread (for people using threaded mail)/in my
last mail (for the rest), I'm working on the "split up the frames into
textured triangles and output textures and coordinates" idea. The idea
is to find edges in the image. So far I have a Sobel edge detector, a
wavelet transformer (to compress the textures, still very incomplete,
transform only), and some

compressed audio tutorial - 2nd draft
I've updated the "Introduction to compressed audio with Vorbis" tutorial
based on the many good corrections and suggestions I got here.
Changes were:
fixed range of 16bit samples (-32768 to 32767 rather than 0 to 65535)
added sentence on why 44.1KHz was chosen for CDs
added Sony's name as developer of CD format

PlusV algorithm
Important (imho)!
I found this site in the internet:
http://www.plusv.org/
PlusV is an audio enhancement algorithm similar to SRB of Mp3Pro, but
1) better than SBR
2) Fully open-source
It seems to me wise to include PlusV into new versions of Ogg Vorbis.
P.S. what about some long-awaited features in Ogg Vorbis?
1) ability to turn off the frequency filter in the encoder (especially for high

Hi everybody,
I was just wondering if there is a DRM (Digital Right Management) solution to use with ogg vorbis.
Any information welcomed.
