Nov 15, 2012 2:18 AM in response to BonJovi101by turingtest2,With Sound Check active you should find that all songs have roughly the same "loudness".

Nov 15, 2012 12:17 PM in response to turingtest2by BonJovi101,so when i load songs to itunes they should automatically be the same volume as the ones already on there. When i turn sound check on on my iphone my songs all sound different some really low and some really loud but when i turn sound check off all my songs have about the same volume now why is that

Nov 15, 2012 12:37 PM in response to BonJovi101by turingtest2,Perhaps the control is back to front on the iPhone, or the iPhone doesn't have the correct normalization data. It's not a feature I've personally tested.

Nov 15, 2012 1:32 PM in response to BonJovi101by turingtest2,In theory. Normallization software should determine the overall "loudness" of each track and store a value which can be used as a correction factor so that quieter tracks are amplified more and louder ones less. This should mean you don't find yourself having to turn up the volume on quiet tracks and then rip the headphones out of your ears when the next one is too loud. How well it works in practice is probably a subjective experience.

There are 3 different SoundChecks: iTunes playback, iTunes burning, and iDevice playback. None of them work properly. They never have.

Dec 3, 2012 2:13 PM in response to turingtest2by Gary K.,I think the suggestion that Sound Check is a subjective experience definitely has merit. I listen to a lot of podcasts and the overall audio volume varies considerably. The dynamic range also varies. One podcast in particular, "Beauty and Da Beast" (note--this is explicit) is very bad this way, with the comedians going from overdriving the mic to whispering.
After applying Sound Check, I judged the podcast to be listenable on my Mac, although it continues to be unlistenable with earbuds. Despite my perception, there is no evidence that Sound Check offers dynamic range compression at all. It could be that it messes with the equalization. I don't know, but I guess I am willing to be humored--at least on my MacBook Pro with built in speakers--with material that I really want to hear despite its production snafus.
