Listening test. Who wants to participate?
This is a public listening test. If you want to participate, all you have to do is download the file below (ca 35 MB), the listen to the songs and decide which the files have good quality. You can select several options, so if you found quality acceptable at say, 32 kbps, then select the higher bitrates too for an accurate count. Compare the files against the original MP3 file and listen. If you hear no difference, then vote for that one. Of course, you can also post a comment as to which quality you found acceptable to listen to, but not perfect when comparing to the original file.
Note that there are different versions of the files. HE-AAC + PS, HE-AAC only and LC-AAC. They're the same compression, but still different. I ask that you at least listen to each of these three versions, because quality may vary at different bitrates for the three different versions.
Also, if you find quality acceptable at some bitrate, you really don't need to listen to the higher bitrates. They'll be perfect, too (but remember that if 32 kbps HE-AAC + PS sounds good to you, doesn't mean 32 kbps HE-AAC will, because they're different; though 40+ kbps HE-AAC + PS would sound perfect).
All files (except for the original) are encoded with AAC.
Oh and ignore HE-AAC @ 72 kbps, HE-AAC + PS @ 72 kbps, LC-AAC @ 24, 32, 40 kbps. I had to cut out some because the poll can only take 20 choices.
But if you really have to choose 'em (like HE-AAC only sounds good @ 72 kbps), then post it. Same goes for the low LC-AAC bitrates, only you can vote for the higher bitrates in the poll. But do post that you originally thought a lower was better.
IMPORTANT NOTE: To play back these files, please use ffdshow (download here) and set AAC decoding to libfaad2 for proper playback! If you do not, then I ask you not to vote since the results may be inaccurate.

File contains an original MP3 @ 320 kbps plus HE-AAC + PS @ 24-72 kbps, HE-AAC only (no PS) @ 24-72 and last, LC-AAC @ 24-104 kbps.
Let me know the results of the encodings. All encodings were done with Winamp's encoder, though LC-AAC was done through BeHappy.
Questions? Post 'em. I'll answer.
Don't worry, this isn't hard at all. Just use your ears
