Revision as of 10:36, 26 January 2006

  • 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 and lower bitrate down to 32 Kb/s (q-2). AoTuV beta2 was adopted as a part of Vorbis 1.1 of Xiph.Org. Note that this patch also include the Vorbis-OptSort patch. Quality test of AoTuV beta4 vs. libvorbis 1.1.1:
