TwinVQ versus The World
The last few threads have really been interesting. Technologies
that are currently on the market are MP3, RealAudio, and Windows
Media (pre-version8). Technologies currently in progress or
just shipped are Ogg Vorbis and mp3pro. I don't think anyone
has mentioned TwinVQ on this list. While exploring alternatives
to MP3 (which is when I also found Vorbis), I noticed TwinVQ. I
encoded a few tracks with TwinVQ and they sounded like shit, but
does anyone still consider TwinVQ a serious competitor in the
compressed audio market? Does it have _any_ advantages ove...

An handful of tags !
Another problem I would like to speack about : tags. Each format appears to
create its own tag.
TwinVQ and WMA tags are limited but Mp3 has a good tag system (although the
"genre" category could be improved). Now ogg develops a new kind of
tagging. I imagine converting all my tags with thousand of tracks... real
nightmare...
Is there an authority or a project to standardiza tags ?

Vorbis transform description
...this
way.)
The trick is that the floor curve tends to have formant-like features
due to the rolloff properties of masking tones. These can be encoded
into a low-order IIR LPC filter (20-30 poles, simplified direct form
II. Basic speech compression stuff). Speech compressions (and, I
might add, TwinVQ [VQF]) encode 20 pole systems into 20-28 bits. With
a little effort, a standard algorithm like Levinson-Durbin can be used
to generate a filter with a frequency response within a few percent of
the desired curve across the spectrum.
Unlike speech compressions and TwinVQ, Vorbis never applies the...

Non-problem, just a Ogg/Vorbis question.
I must be living under a rock, im on the icecast mailing list, but yet do
not quite understand exactly what Ogg/Vorbis is.. What information I think
I know is this.. People behind proxy's like it, and its not exactly
Mp3... hehe, anyone care to help clarify?
Thanks

AW: What's in a name
...sting story.
Ogg Vorbis is the current CODEC in development as part of the Ogg multimedia
project, begun immediately after Fraunhofer issued its 'Letter of
Infringement' to freeware MP3 encoder efforts. Vorbis is intended to go
head-to-head with the two current MPEG-4 compressions, AAC and TwinVQ.
