Well, Vorbis audio is actually better measured by its "quality" than its
bitrate. Some of the 3rd party software, however, doesn't realize this, or make
it clear, which provides for a poor example to people just trying it out. The
quality setting has to do with the default encoding method which is variable
bitrate (VBR).
For more information on the Ogg Vorbis quality setting (I use "6"), see that
section of the FAQ:
http://vorbis.com/faq.psp#quality
The FAQ doesn't mention that, depending on the capabilities of your encoder (the
command-line version supports this), the quality scale is more finely-grained
than it at first appears. You don't have to choose between "5" and "6" - if you
want, you can pick "5.99" (a popular one for many) or anything else....
I find that, encoding at "6", I get files around the same size (usually a tad
smaller) as I used to get encoding with LAME using the "--alt-preset standard"
preset on the command line. And the Vorbis quality is much better, IMHO.
As far as I can tell, you could encode at quality 3 or 4 and get a noticible
file size reduction, yet have the same or better quality than 128kbps or 192kbps
MP3 files. The only reason I encode at the higher 6 is that I use my digital
audio as a sort of "backup" for my CDs, and so it's nice to have the same file
size, yet better quality.
And the totally free nature of the vorbis codec is a bonus... I know for
certain I'll always be able to play my .OGGs :)
On a related note, Proem now offers his live shows for download in Ogg Vorbis
format instead of MP3 at his proemland.com site...
