I'm completely furious about this...
There is ABSOLUTELY NO EXCUSE FOR IT WHATSOEVER... its completely straightforward to make the audio play without errors. In the first place ALL code that somehow modifies the audio, eg, volume control, volume levelling, EQ etc should be disableable...
I am especially annoyed about this... I used iTunes to check some masters recently returned from Metropolis in London... there was in some tracks what sounded very much like clipping distortion. I rang round the band and the other engineers who worked on the album to inform them that the planned run of discs would have to be cancelled because the whole album would have to be re-mastered. A week later, in an idle converation, someone happened to raise the issue of where the volume control in iTunes should be positioned for unity gain.... Naturally I have always assumed that full was unity... but it turns out, the signal is boosted into clipping!!! WHY may I ask have Apple removed the option to disable the volume control?? Do they know that soem folk use iTunes with an Apple router into a high qualtiy coverter for the digital sound input for their hi-fi (yes, some of us still have them)...
I am hugely disappointed by all this... I have been an Apple fan for years and always trusted their products,,, but relatively recently I have discovered that Logic's summing is inferior and reluctantly converted to Pro-Tools...
Apple, are you listening??? If you don't sort these relatively simple problems out very fast you will lose me as a customer... and then you will lose the organisation I work for since I decide what computers we use in the studios....
Come on guys... Steve Jobs must be turning in his grave...
