Does that make Helix the new recommended MP3 encoder, or has it to be LAME because it's open source?
I'm sure I've seen smaller, recent, ABX-tests where Lame has outperformed Helix quite clearly. I think Guruboolez and maybe also Halb27 have done a couple, but I might be mistaken. ...
... Could these two arguments qualify Helix for the new recommended MP3 encoder? ...
Excuse me, but what is the correspondance between the files and the encoders ?
Sorry, it's not clear to me how many subjects participated. Can you point me to that in the graph?
Oh, and Greynol is right. Helix is not winner. It is tied. The differences are within the confidence intervals, which means that they are just random. If you redid the test with the same samples and same listeners, the simple fact the ABC/HR presents them in a different order every time would probably lead Lame, or Fraunhofer, or iTunes to get a slightly, but not significantly, superior score. We must consider this to be chance, unless we have more information to backup further claims.
agreed. Probably the zoomed plot window should be removed, since it's quite misleading and doesn't show any useful information.
