aoTuV (Aoyumi's Tuned Vorbis) is a third-party development/tuning of the Vorbis encoder.

aoTuV versions improve significantly on Vorbis quality: Most people agree aoTuV beta 4 (and newer) achieves transparency at -q 5.

Released in December 2005, aoTuV beta 4.51 improved further on low bit-rate and after peer review was rebranded aoTuV Release 1 with some reports that -q 1 (approximately 80 kbps) is good enough for streaming.

In June 2007, the aoTuV beta 5 versions including 5.7 underwent peer review and superseded Release 1 as the HA recommended Vorbis encoders, improving the low bitrate quality in relation to Noise normalization without sacrificing compression ratio.

aoTuV beta 6 versions released in 2011 made further improvements on pre-echo and post-echo handling, stereo mode decisions and noise normalization at low bitrates but have not been extensively peer-reviewed by the HydrogenAudio community.
