After assisting like many of you on the controversy of guruboolez' tests concerning the Nero AAC encoders and having seen many suggestions towards preparing a listening test around 48kbps - in particular with the different HE encoders, I decided to take matters into my own hands. I currently have 8 samples testing for tonality, transients and stereo separation. These are generally classical music, but also include electronic music, 80s pop, and I might add a jazz recording for ambience reproduction. As for encoders, I'm stumped. Should I also include an old version of nero (old being relative) as to see the progress in a general evaluation ? At this bitrate, many encoders is not really a problem, is it? For now, I was thinking : -Nero AAC Tape / PNS Enabled / HE / High (Should I enable hint track?) -Ogg Vorbis, latest AoTuV, q -2 to -4 (whatever's approximately the same bitrates ~42-53) -Lame ABR 48 (any tunings suggested?) -mp3pro, probably, at any close bitrate I can achieve (adobe audition's encoder) -Itunes AAC (HE if available) -CT encoder (winamp 5.12) 48kbps, HE. If I should use an older nero as well, where can I find it? Also, could anyone help me prepare the ABC/HR logs? (eg, Sebastian Mares) Thanks in advance, Tristan.

On the other hand, that leaves you with only Ogg Vorbis as format other than AAC. Anyone knows how WMA Standard 9.1 is supposed to perform at this bitrate?
