Sometimes computing axioms get started that no-one bothers to go and check, or recheck, later on. They just get repeated parrot-style over and over until everyone believes it. A bit like religion.
One of these axioms is “The iTunes MP3 encoder sucks. Use LAME instead, it’s better.”
Well, thanks to the efforts of Sebastian Mares, who organised a mass listening test of various MP3 encoders at 128K, we now know that this is in fact, not true.
You can read the detailed results for yourself here, but the short version is that iTunes, LAME, Fraunhofer, and Helix, all perform near identically and all sound excellent. LAME was in fact the slowest of these four, although encoding speed isn’t usually an important distinction.
So the next time you want to jump through hoops to avoid using the iTunes MP3 encoder – don’t bother. It’s just as good as LAME.
Lame destroys itunes. Use -V2 (new alt-preset standard).
oh, cmon man .. the test is in 128kbps! and I suppose you know that alt-preset-standard produces at least 160kbps files!
I am quite satisfied with the sound quality of iTunes mp3 encoder … But … After Ripping a HUGE library to mp3 with iTunes … and then updating to (iTunes 9) … my iTunes will not: Play, or Import, any of the previously Ripped files.
Did they upgrade the mp3 encoder to a version that is not compatible with previous versions?
Nope, MP3 is MP3.
Wow, are you really going base your statement on subjective listeners? The test didn’t even use the same bitrate for each encoder. Of course Itune’s mp3 encoder will sound better than lame when it is set to a high bitrate. Nice try.
What the hell are you talking about? All the encoders were set to 128K, did you even read the linked article?
And yes, I’m going to base it on “subjective listeners”, because that’s the whole point – to determine the perceived quality of the resulting compressed audio. You can’t measure that. Perceived quality is, by definition, a subjective quantity, which is why the survey uses a large number of listeners.
