[vorbis] Is this just anti-Ogg FUD?

I have used both MP3 and Vorbis in a disco/club environment through both old
(3 to 5 year old PA equipment built into the venue) and new (Digi001 & TOA
PA system) sound equipment. Nobody notices any difference with the digital
medium- with the exception of the lecturers, who noticed something unrelated
(i left the EAX normaliser on by accident). If you are bothered about a
audio format losing precious data, use a lossless one, or make your own (or
donate lots of money to people like Xiph lots of money and ask them nicely
to make you one).
PS- noone cares- they're all drunk anyway (i will upload picture examples
from the next gig i do)

Neither can I, but to paraphrase whichever person it was who did that speach
on patent law, "patents are stupid ideas"

Theres an Ogg project that uses wavelets somewhere (Tarkin i think) so i
shouldn't think it'd be too (relatively) difficult for Xiph to rollout a
wavelet based audio codec

If you are bothered by loss of audio quality then you shouldn't be touching
lossy audio- go for lossless audio. formats like Monkeys Audio, FLAC,
Shorten & Wavepack. If it wasn't for the lack of HD space & the fact that
the average consumer can't tell the difference between CD Audio & Vorbis,
then i would've gone for lossless audio. But i havent- i just deleted all
the crap mp3s i had.
