A Red Cat’s Journey, Enhanced by iTunes – New York Times
Then Mr. Cooder noticed something else: When he burned a copy of the album using Apple’s iTunes software, it sounded fine. He didn’t know why until one of his younger engineers told him that the default settings on iTunes apply a “sound enhancer.” (It’s in the preferences menu, under “playback.”) Usually, that feature sweetens the sound of digital music files, but Mr. Cooder so liked its effect on his studio recordings that he used it to master – that is, make the final sound mixes – his album. “We didn’t do anything else to it,” he said.
Mr. Cooder is most likely the first well-known musician to master his album using iTunes, but other producers have also noticed its effect.
If this wasn’t the NYT, I would think it was a hoax. Well, what happens when the same algorithm is applied to the music twice, once by Ry Cooder and for the second time when somebody listens to his music on iTunes? Would it be like adding an EQ twice and possible over-doing it?
