include aoTuV patch
Would be nice to include aoTuV ![1] patch to libvorbis. aoTuV is an improved libvorbis encoder, that, while keeping ABI compatibility, gives many improvement:
- better quality at all bitrates versus libvorbis-1.1.2 ![2], giving aoTuV better quality than other codecs (AAC, MP3, MPC, WMA, ...) ![3];
- support of quality down to -2 (32kb/s at 44kHz stereo), versus -1 (45kb/s at 44kHz stereo) of libvorbis-1.1.x;
- encoding speed 10% better thanks to the included Vorbis-OptSort patch (improve ordering loop).
aoTuV Release 1 is the 'stable' release, while aoTuV beta 5 is the latest 'beta' release. aoTuV version have been tested and found to have a better quality by the audio community (especially on hydrogenaudio forum ![4]) and this is the reccomended vorbis encoder ![5].
Note that, e.g., ffmpeg2theora binaries already includes aoTuV beta 5 patch.
