OGG options in CDex and EAC, what is best?


Question

OK, i have been using OGG and CDex for a while now, been using CDex with OGG quality at 4 and I think that a little better than 192kbs MP3 with about 25% less file size. Anyways, I gave EAC a try the other day and saw that it used the oggenc.exe instead of the vorbisenc.dll like EAC. It also rips the entire track first then encodes it, while CDex ripps and encodes on the fly. So I ripped that same song and the EAC got a file size about 4Kb larger, yeah thats small but I just wonder what way is best, I am really picky about that, or does anyone know a good forum about this stuff. Thanks.

update, i just saw an option in EAC that limit the ID3 takes to 4KB so maybe thats it.

Speaking about EAC, how does Feurio! compare to EAC in terms of MP3 decoding/encoding and CD Audio ripping?

It shouldn't really matter.. CDex uses a couple of DLLs to work, EAC uses the commandline oggenc. The difference is probably due to .. different versions from CVS??

FYI, CDex has secure ripping mode as well.. Paranoia mode ... and as for EAC's secure ripping, I've heard that it *might* heat up your CD real fast.

What does the "Quality" setting mean?

Beginning with libvorbis 1.0rc3, audio quality is no longer measured in kilobits per second, but on an arbitrary scale of 0 to 10, called "quality." This change in terminology was brought about by a tuning of the variable-bitrate algorithm that produces better sound quality for a given average bitrate, but which does not adhere as strictly to that average as a target.

This new scale of measurement is not tied to a quantifiable characteristic of the stream, like bitrate, so it's a fairly subjective metric, but provides a more stable basis of comparison to other codecs and is relatively future-proof. As Segher Boessenkool explained, "if you upgrade to a new vorbis encoder, and you keep the same quality setting, you will get smaller files which sound the same. If you keep the same nominal bitrate, you get about the same size files, which sound somewhat better." The former behavior is the aim of the quality metric, so encoding to a target bitrate is now officially deprecated for all uses except streaming over bandwidth-critical connections.

For now, quality 0 is roughly equivalent to 64kbps average, 5 is roughly 160kbps, and 10 gives about 400kbps. Most people seeking very-near-CD-quality audio encode at a quality of 5 or, for lossless stereo coupling, 6. The default setting is quality 3, which at approximately 110kbps gives a smaller filesize and significantly better fidelity than .mp3 compression at 128kbps.
