Just found this article via twitter, circled among mastering "engineers" (in fact Heba Kadry reposted it, the girl who mastered the latest Mars Volta album, which reaches -12.79 dB on my RG scans, and is generally mastered in a horrible fashion).

This further backs my impression that most of them don't have a single clue of what they are doing. The section about the mastering practices of Rubin and Meller are especially eye-opening to me. Masterdisk "engineers" also apparently are now out to rape the Rush back catalogue. Further down they cite phase-reverse tests to prove AAC files are different from the original (wow, REALLY?).

The good thing is, I can use this article to decide which releases to avoid in the future. But I'm really at a loss what we can do beside that. I'm really fed up with mastering "engineers" destroying music releases.

I think you're being a little harsh on the article.

Thats round the wrong way, the article said the waveform shapes were not the relevant factor it was the person skeptical of mastered for itunes that was looking at the sum of two file with one inverted.


From the Author

Thanks for sharing the article, Kohlrabi. If you have another read of it sometime, I think you'll find it's pretty even-handed.

I get the sense that you disagree with the claims made by the mastering engineers, and not with the article itself, which tries to take a neutral stance.

Since this was piece of reportage, rather than opinion, I wanted to accurately deliver the news, present both the commentary and the criticism, and to offer some dispassionate analysis of both stances. The article tries to remain skeptical of the magnitude of the claims, but I also stand by the fact that it's unfair to dismiss them entirely without proper tests.

If you do want to read an opinion piece, you'll probably find that my own feelings about blind listening are pretty congruent with the philosophy here at Hydrogen Audio. I'm a big supporter of this site and of ABX tests in general, and I even wrote a supportive opinion piece about blind listening tests in the very same issue you cited! (You can read that here):

"Can You Hear What I Hear? A Guide to Listening Blind"

I will have to disagree with the extreme stance that mastering engineers are generally snake-oil salesmen (I've never had an experience that would lead me to believe that) or that Mr. Ludwig or Ms. Kadry are incompetent (I know both, and they're definitely not).

However, as a matter of personal opinion, I would agree that Rick Rubin overstates the audible differences normally found between high-res AAC files and their original WAV masters. I'd also agree that at least one of Meller's comments was probably more figurative and expressive than it was literal.

With that said, the engineers I interviewed told me that in "Mastered for iTunes", Apple also fixed an actual issue they had in the past with creating AAC files from high-resolution masters. To be fair, even Bob Ludwig agrees that 256kbps files won't necessarily sound any worse than traditional CD files - Just so long as they're created properly, and the engineer can verify there were no issues with the transfer. (He says that this is something that they're now able to do.)

The other real development appears to be that MEs can now easily and effectively hear the differences between their original master and the file that the iTunes store's proprietary encoder will create. (I'm told that, for better or worse, it's not the same encoder used in the consumer version of iTunes.)

Who knows? Even if the AACs sound identical in 95% of cases, this new ability to actually listen and check can't be a bad thing

Personally, I think the new tools are a good idea, but I'm not about to replace my music library with new "Mastered for iTunes" versions anytime soon.

I definitely appreciate the healthy dose of skepticism here on Hydrogen Audio, and would agree that people who have a service or product to sell sometimes dramatize their claims... But show me a salesman who doesn't, and I'll show you a salesman who's out of a job!

Thanks again for the share and the comments. Keep doing what you guys do!

Very best,
