Well the only thing missing is psychoacoustic model.
Besides it produces good quality at high bitrate. There is still a peak
problem with mp2 notified in roundup, but it does not seem to appear
when floats are used in encoding.
I don't think you can compare vorbis encoder state to mp2 and ac3.
What's another good ac3 encoder open source ?
Still I'm not necessarily happy to drop vorbis encoder but its state
does not seem to attract any developper, so there is not much we can do
about it. Could AAC encoder work benefit Vorbis ?
