compressed audio tutorial - "major" update
I've made a large update to the introduction to compressed audio. I
completely rewrote the first section, which I wasn't happy with. It now
features two diagrams (worth 1000 words each!), and is broken up into a
couple of sections.
http://cs.leander.isd.tenet.edu/~mitchell/vorbis_intro.html
I have also continued to tweak other sections based on feedback from email
and this forum.

Re: An introduction to compressed audio with Vorbis
On <http://cs.leander.isd.tenet.edu/~mitchell/vorbis_intro.html>:
"Each snapshot has a 16-bit number for the "loudness" of the sound,
meaning that the scale is fairly fine-grained - it ranges from -32,768
(complete silence during that snapshot) to 32,767 (the loudest volume
measurable)."
That's not correct. A single sample is not meaningful by itself; each

Where's the tool to do .ogg bitrate "peeling"?
Hello.
The page http://www.vorbis.com/faq.psp (last faq) and
http://cs.leander.isd.tenet.edu/~mitchell/vorbis_intro.html both state
that it's possible to lower the bitrate of an existant ogg enc file
without reencoding. Where does this feature exists? oggenc only likes wav
files as input, how can I feed it an .ogg file and get a lower bitrate
in a new one?

mp3 quality vs Vorbis 1.0?
Many of you have read and my "introduction to compressed audio with Vorbis"
and given me excellent feedback. But with 1.0 about to hit the streets, I
figured I'd freshen it up a bit.
[ http://grahammitchell.net/writings/vorbis_intro.html ]
In particular, it contains two paragraphs discussing the relative quality of
Vorbis vs mp3 at a certain target bitrate. These figures seem

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.

LADSPA stands for Linux Audio Developer's Simple Plugin API (see

architectures and all were different. So they fleshed out a plugin API

Firefox plugin to auto convert audio files into Ogg
per > http://forums.fedoraforum.org/showthread.php?t=63653
The above thread on the Fedora Forums about a script that can
automatically convert one audio format to another got me thinking >
wouldn't it be fantastic to be able to right click on an MP3 (or other
audio file) while in Firefox, and automatically have the file
converted into Ogg at the same time as the file is being saved

Launch of OggHelp.com
Hello everyone,
I would like to bring to your attention the new website that I have been working on. It is a portal for articles, links, and support for everything related to Ogg Vorbis. It just started and hopefully will be evolving rapidly.

I have modeled it after the group of successful Help pages such as http://VCDHelp.com and DVDHelp.com.

patents and separate entropy coding
Hi everyone,
first of all, I searched through the archives for any posts resembling
this, I didn't read all posts about the patents so if this has been
suggested before I apologise.
I read in an article on C|Net (I think, it was linked from Slashdot
anyway) that Thompson are threatening to sue you if Ogg Vorbis becomes a
success. Which is evil, and I'm also mad at them because they never

RC4/1.0 and peeling
first, congrats to monty and the whole crew for getting
this close to 1.0. it's a monumental achievement reflecting
a huge amount of hard work -- kudos!
econd, i know the bitrate peeling feature has been pushed
back until after 1.0 is out. but i'm wondering -- will oggs
created with a 1.0 encoder be peelable with an as-yet-unreleased
utility, or do "peelable oggs" have to be

Applying dynamic compression to live audio
Hi:
I want to stream audio from my soundcard, but I'd like to apply some
dynamic compression to it first (ala winamp's audiostocker plus shoutmuxer
thingy). I heard rumours of compression in liveice, but Iv'e been told
that this only works when it plays from prerecorded MP3, not the live
input. I'd like to do this with darkice, but can't see how it could be
done. I guess

badly-configured SMTP daemon?
One of your users, "nizar_lethif" is subscribed to the [vorbis] and
[vorbis-dev] mailing lists at xiph.org. His mailbox is full.
Any time anyone posts a message to either of these lists, nizar_lethif is sent
a copy (as expected), which bounces because his mailbox is full (also as
expected). The problem is that the bounce message is sent to the *person who

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