I was using Ogg Vorbis for several moths already, but mainly for low and mid-range bitrates. I still like it's sound at -q0 (Good enough for sharing previews and small music clips) and it's good for me at -q6 when I'm listening to the music on computer. I'm thinking about a next step: start archiving music with it. Well, I'm actually using Musepack --standard for this purpose, but in some reasons I could have to make some backups in OGG. Could experienced answer few questions about it?
Please, don't answer, like "do ABXing". It takes quite a long time to make opinion about a codec. And I'd not liked to find out someday that several files I can't reencode sound crappy.
I know, that Garf was trying to make "transparent" Vorbis compile, GT3. How good is it and what bitrate shall I use to have safe encodes? I have no problems with MPC q5 and LAME --ape. What about OGG? How often it fails? Is it "better", than MP3 (I mean artifacting and transparency at 190-240kbps bitrates).
Sorry if this was answered many times before...
Full Version: Vorbis archiving
1) It's Vorbis, or Ogg Vorbis, not OGG.
2) Try Version GT3. -q6 is where the lossless stereo coupling kicks in, and where a nice difference is made on problem clips, so if you want to have arcihval quality I'd recommend you start at -q6. I use -q7 since it's just one up from the lossless stereo coupling.
See if -q6 or -q7'd work for ya. And if you're going to encode a lot, I'd recommend to wait until GT3 is finished.

Don't assume that something which is true for 1.0 also is true for GT3. As a matter of fact, I forgot whether GT3 does lossless coupling from -q5 on or not.
I second your recommendation, GT3 -q6 or -q7 should be fine. It'll never be perfect though.
I may do some GT3 work tonight, but when anything gets released I have no idea, so don't ask me
At the moment I'm using GT3b1 at -q 6 for archieving (I don't have much space left...). I can't hear any artifacts but in silent passages when I turn the speakers/headphones loudly I realize that there is more noise than in the original .wav.
I recommend waiting for the final GT3.
