aoTuV b6.03 oggenc+libvorbis slightly diff outputs; why/which is best?, [TOS #6: was "Ogg/Vorbis Lancer builds"] Options

[Anakunda]

HI!!
As you know there's published new oggenc and libvorbis Lancer builds based on aoTuV b6.03. So regarding it's writing library they should use the same code, however looking closer on the result the Lancer builds give slightly different output:

Comparing:
"C:\Users\Anakunda\AppData\Local\Temp\aoTuVb6.03.ogg"
"C:\Users\Anakunda\AppData\Local\Temp\Lancer.ogg"
Differences found: 1179627 sample(s), starting at 0.4542404 second(s), peak: 0.1180483 at 30.8317687 second(s), 2ch

So obviously I'm interested where's the difference and which builds are expected to give more transparent output. Thanks!

As john33 said (and according to this Wiki page) the difference in stream between aoTuV and corresponding Lancer build is cosmetic, and nobody should be able to spot it. However, the newest Lancer build is from 2006 (based on aoTuV b5) and you are comparing it to b6. Between b5 and b6, there've been some optimalisations to low bitrates, and aoTuV is bound to perform slightly better.
