AoTuV
aoTuV is an abbreviation for Aoyumi's Tuned Vorbis; it is third-party development/tuning of the Vorbis encoding algorithm.
aoTuV versions improves significantly on Vorbis quality: Most people agree aoTuV beta 4 (and newer) achieves transparency at -q 5.
The HA-recommended version is aoTuV Release 1 (which is actually a re-branded aoTuV beta 4.51 after undergoing extensive peer review). It improves further on low bit-rate quality in relation to Noise normalization, to such extent that some reports -q 1 (approx. 80 kbps) is good enough for streaming.
The latest version is aoTuV beta 5, which has even more quality improvement on low bit-rate settins without sacrificing compression. This version is currently undergoing peer-review at Hydrogenaudio.
