As I said to my ears. Do you have research to back up your initial claim? If so, I'd like to see it please.
Hi again,
The synth sounds in these three programs are centered around the same plugins, the same sample and loop libraries, and the fx also come from the same code, coded by the same people - which basically are the same Emagic guys that worked (and sill work) in Rellingen, Germany, with a few exceptions. If you would install Logic and Garage Band two different hard drives, and check eg. the sample library, you'll see that the files they share have the same size, length, creation and modification date. Logic 8 has a few goodies that Garage Band doesn't, like the Space Designer - which used to be a separate plugin costing several hundreds dollars, but this is a reverbs that sounds
better than the GB reverbs. The JamPacks that are included with Logic 8 are the same JamPacks that were included with Logic 7, except that they take a little less space on your drives due to Apple's lossless compression format.
a better understanding of AD/DA conversion has placed Protools (and others) in the position of being a perfectly acceptable replacement for my trusty Studer 820.
The sound of a DAW depends on the summing engine (32 bit floating in Logic, 48 bit fixed in Pro Tools HD) and the convertors. In terms of AD and DA, Digidesign don't make their own convertors, and Pro Tools can be used either with 192 I/O or with interfaces from Apogee (AD16X and DA16X) and Lynx (Aurora). Not all, but most people agree that these interfaces from Apogee and Lynx sound better than Digidesign interfaces, which probably is because they are newer (they are also faster).
The same interfaces can also be used by Logic or even Garage Band). So - if we talk about summing, it comes down to the difference between 32 bit float 48 bit fixed, and if you buy the DAW summing comparison CDs, or read what's written about them by people who have bought these blindfold listening source material, you'll discover that there isn't any agreement that Pro Tools HD came our better. Not even Digidesign claim that. Personally I agree that old, analogue gear often sounds a little bit better, especially in the low end, but both Logic and Pro Tools users can use external, analog summing boxes or analogue mixers if they want.
I've seen people claim that Logic sounds better then PT, that Pro Tools sound better than Logic, that Logic 8 sound better than Logic 7 and so on, but nobody I'm aware of have been able to produce a 10 seconds long stereo file demonstrating it. I've sold my Pro Tools HD rig, but made some comparisons before I got rid of it, and couldn't produce anything suggesting that one PT HD sounded better that Logic. I still have Logic 7 and Logic 8 on my drive, and we could always - just for fun - make some comparisons if you can specify what it is that you think is worse in Logic 8. I thought you referred to the audio engine, which has been discussed up and down (eg
here), but if there are samples or loops or synth engines you think have changed to the worse, we could always waste some time on comparing files.
Just now, I actually found a thread discussing if Logic 7 sounds better than Logic 8 (not the audio engine, but the plugins) - it's
here...
