History

(For a highly detailed description of Vorbis historic, check out OggZealot's Ogg Vorbis Historic where Monty also adds a few more details too). Ogg Vorbis reached version 1.0 in July 2002. It is the official Xiph.org encoder (the one you get from vorbis.com). HA codec developer, Garf, did his own tunings, based on version 1.0 to produce GT3b1 and GT3b2. Both encoders showed improved pre echo handling for q values of 5 to 10. It was later judged in an internal listening test that GT3b1 was the better of the two. There was a minor bugfix update earlier that year in March, which only appeared in the CVS at Xiph.org. This consisted of very minor bug fixes, which do more to correct odd problems that may occur rather than improving quality, including (garbled noise output and gaps in streams). This was referred to as Post 1.0 CVS. Quality problems that mainly affected low bitrates were later addressed in a new bugfix (1.0.1) that was released.

Post 1.0.1 CVS was released late December 2003 by Monty at Xiph, and includes true CBR. In order to simplify the situation where we had two encoders (1.0.1 and GT3b1), OggDropXP developer John33 merged the sources to give us GT3b2. Once the 128 kbps multiformat test was completed, Aoyumi's aoTuV Vorbis tuning was determined to be the best Vorbis encoder. After the success of aoTuV beta 2 encoder, Xiph.Org merged their tunings into the official CVS branch to produce the long-awaited Vorbis 1.1. Aoyumi's latest release of aoTuV beta 4 encoder as of November 2005, however is now the recommended encoder by 3rd party developers at Hydrogenaudio.

Windows binaries

John33's oggenc2.8 is a special version of the Ogg Vorbis encoder. "Features include compression from lossless files (Monkeys Audio, LPAC, FLAC, OptimFROG, WavPack and Shorten - requires presence of decoders), and the ability to specify 'padding' in the headers for subsequent insertion of Tags." (from Ogg Vorbis page at rarewares)

• aoTuV beta 4.51 (MSVC compile)
• aoTuV beta 4.51 (ICL compile for P3/AMD Athlon)
• aoTuV beta 4.51 (ICL compile for P4/AMD Sempron, Athlon 64))

If you prefer a nice drag-and-drop interface, then you can try John33's OggDropXPd (Windows only). "Features include compression from lossless files (Monkeys Audio, LPAC, FLAC and OptimFROG), auto-tagging, renaming of encoded files, setting of advanced encoder parameters, use of VorbisGain tags on decode, Playlist (.m3u) creation, and others." (from Ogg Vorbis page at rarewares)

• OggDropXPd aoTuV beta 4.51 (MSVC compile)
• OggDropXPd aoTuV beta 4.51 (ICL compile for P3/AMD Athlon)
• OggDropXPd aoTuV beta 4.51 (ICL compile for P4/AMD Sempron, Athlon 64)

(work in progress, guide will be completed soon)

Linux binaries

• oggenc aoTuV beta 4.51 and libogg 1.1.3 (static gcc 4 compile) with impulse_trigger_profile

The Static GCC 4 binary was compiled by QuantumKnot.
