Thanks for all the great responses on tools to use - I have Exact Audio Copy and CDex working very well, and I've been working out all the kinks. Two questions, one very Vorbis related, one not :) 1) I know people have asked many times "What quality should I use". Well, I want to ask it again but in a narrower frame. I see less than 10% difference in size between 4.99 and 5.00 - what's the big difference? Is going to 5, albeit .00 much better than 4.99? I can go to 5.99 for another 15-20% size hit.. is it worth it? Where does it end? :) 2) Exact Audio digitally extracts at 8-9X, while I can't get CDex to extract higher than 1-1.5X. Any ideas? Is this common to CDex? Is there a favored mode people have in CDex? <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

Where does it end? :)4.99 was a "special" number in rc3 - since lossless stereo coupling kicked in abruptly at 5.0 and there was a noticable size jump between the two. In 1.0, I believe the threshold has been bumped to 6.0, and the transition is smoother - so the size jump shoulnd't be so abrupt. I believe that for most people, this is only likely to be a concern if they use a pseudo-surround systems that generate a surround image from a stereo signal - you'd want a good quality stereo signal for that! As for the quality between 5.0 and 6.0? hell, don't ask me. I could barely ABX RC3 at -q2 with my ears and hardware! .../Nemo <p><p><p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

At 5.00 lossless stereo coupling is enabled. As a result bitrate jumps quite a bit between 4.99 and 5.00, for a small quality increase on most samples, although on some samples lossless stereo is a big advantage. Generally though 4.99 sounds very similar to 5.00 and shaves off some redundant stereo image.... Again, you need to listen to see if you can hear the difference and decide if the bitrate hit is worth it. Cdex verifies the CD and reconstructs scratches etc. i.e. it will decode an error free rip, every time. I don't know if your Exact Audio setup might do this. You can expect a *large* performance hit for perfect verifyed audio extraction...

It sounds like EAC is ripping then encoding while you have CDex encoding on the fly - I haven't seen any compile of vorbis which'll encode at 8-9X. On my PIII 850 CDex manages ~2.5X whether I have extraction set to standard or paranoia. <p>> 2) Exact Audio digitally extracts at 8-9X, while I can't get CDex to extract> higher than 1-1.5X.
