Frequently Asked Questions:
Q: How exactly does iVolume adjust my songs?
A: iVolume effectively repairs the built-in ‘Sound Check’ function of iTunes. Information about the loudness is stored by iTunes in a tag named iTunNORM inside your songs. This information is used for playing a song a bit louder or softer at playback time whenever Sound Check is turned on. iTunes’ loudness analysis is very fast but unfortunately not very accurate so that Sound Check is not satisfying out-of-the-box. That’s were iVolume comes into the game: iVolume re-analyzes every song with a professional algorithm that’s oriented on the acoustic perception of the human ear and iVolume then permanently replaces the information in the iTunNORM tag of your songs with perfect values.
Q: Is there any loss in quality to my songs?
A: No. iVolume does not re-encode your songs. It just replaces the information in the iTunNORM tag with perfect values. This information is used at playback-time to play a song softer or louder whenever Sound Check is turned on.
Q: Do I need iVolume to play my songs?
A: No, you just let iVolume run once (or every time you’ve added new songs) over your library. Then you play your songs as usual with iTunes, your iPod, iPhone, iPad, or Apple TV. You just have to make sure to have Sound Check turned on in iTunes or on your playback device so that the adjustments made by iVolume take effect.
Q: Are copy protected AAC songs bought from the iTunes Store supported?
A: Songs purchased before mid 2009 from the iTunes Store may be DRM-protected (file extension .m4p). Unfortunately there is no way for applications to read raw sample data from copy protected songs. If this would be possible, it would not be a copy protection anymore. But to calculate the perceived loudness of a song, iVolume needs to read the sample data of that song.
So copy protected songs can not be automatically adjusted by iVolume. However you can still manually adjust them by hand.
Please note that in the meantime all songs offered by the iTunes Store are in DRM-free “iTunes Plus” format. Songs purchased in this format can be analyzed and adjusted fine with iVolume.
