How is vorbis today? All I hear is vorbis blows (from those whose opinion I respect)
scramled eggs. etc =)

What is happening in the vorbis front?

I think everybody is waiting for RC3. I don't think people actually say Vorbis "blows" at the moment. It's very potential codec. Lets see what RC3 offers...

Vorbis 'blows' about just as much as MP3 'sucks'

The current encoder (RC2) has a few known quality problems that aren't that bad but can be annoying if you are sensitive to them.

For a taste of what it can do, try my tuned version at http://sjeng.org/ftp/vorbis/

RC3 is expected end of next week and should fix the most audible problems in a better way.

Be carefull with whom you respect wink.gif

The current release of Vorbis, RC2, was the first release to implement all of the features wanted for version 1, such as channel coupling. It's had little tuning done, and yet still managed to be rated equal to WMA and LAME MP3 at 128Kbps in the recent listening test.

If a new untuned release sounds as good as the best MP3 encoder, you can expect tuned encoders to sound much, much better.

RC3 will be out soon (for varying degrees of 'soon') with various issues fixed, including rejigging the output stream to support bitrate peeling with much less loss in quality than before.

I don't know who has been saying that vorbis "blows" but thats not really true at all. Vorbis RC2 IS actually pretty good, it just still has a few issues though like Garf says, they may not be so bad to some people. Infact, I think that Vorbis RC2 is providing higher quality than mp3 currently. It probably falls somewhere between mp3 and aac at the moment.

If all that I hear is true, RC3 should attempt to address alot of these issues more directly, though we'll have to wait for it to come out to see exactly what happens.

Izzat pumpkins I hear? Sure sounds like Corgan...?

Sounds good, except that my laptop's souncard is less than stellar, so it has lots of crackling distortion in it.

Humm, the pugs30.ogg is a known problem sample. I think the tuned version does solve the problems there but I'm not sure.

The tuned version itself is oggrc2tune.exe or something like that.

The sample is from The Smashing Pumpkins - Adore.

I just want someone familiar with vorbis to test it...
Thanx for the response m8ies!

Well, the distortion is of the obvious non-soundfile type. You can just tell that its 'overlaid' on the audio, rather than being a part of it. Like static on a radio. It just has such a distrinctly different tonality that you just know it's not the audio itself.

Yeah, this soundcard is a total pos. In case you couldn't tell by now. wink.gif

Haha, I could.

I checked my mail and I'm now pretty sure the ogg up there is one with the problems fixed.

It was originally reported as 'Vorbis loses bass compared to original'. Vorbis has generally very high quality on bass so I investigated further and found it was a stereo noise hiss problem. I.e. the problem was not lack of bass but too much hiss.

The tuned ogg fixes that. But the same person reported that it sounded attenuated compared to the original. As far as I could verify, that's entirely psychological.

I just wish people would ABX before reporting problems biggrin.gif
