- Vorbis-OptSort: This patch improves source code of the Vorbis codec library (libvorbis-1.0) to accelerate encoding time about 10% (not apply clean on 1.1.1).
- AoTuV beta4.51 encoder: Optimized encoder for higher quality. Note that this patch also include the Vorbis-OptSort patch. Quality test of AoTuV beta4 vs. libvorbis 1.1.1:
- Optimized Ogg Vorbis Encoders: these are highly optimized encoders developed by the Ogg Vorbis Acceleration Project that are much faster than the standard builds with negligible to no effects on audio quality.
