Tired of constantly adjusting your music's volume?
iVolume ensures that all your songs play at the same volume level.

iVolume calculates the volume perceived by the human ear for each song of your iTunes music collection. Thereby iVolume gets the most out of the approved Replay Gain algorithm and adjusts your songs accordingly.

* Master of the Genius: iVolume is the perfect companion for your Genius Mixes in iTunes. No longer adjust the volume for background music on parties. No longer dig your iPod out of your pocket just to modify the music's volume. iVolume takes your music listening experience to a whole new level.

* Compatible With Your Digital Life: iVolume integrates seamlessly with iTunes on Mac and PC, iPod, iPhone, iPad, Apple TV, FrontRow, and AirPlay (aka AirTunes). Most popular audio file formats like MP3, AAC/M4A, AIFF, and Apple Lossless are supported.

* Blazingly Fast: iVolume takes advantage of newest technologies to fully utilize every core of modern multiprocessor machines for optimal performance.

* Avoids Unnecessary Work: iVolume remembers all results ever calculated. Apply changed adjustment settings without the need for re-analyzing your songs.

* Keeps Albums Intact: By using a sophisticated album detection algorithm iVolume optionally adjusts albums as a whole to keep the intention of the artist. This method is particularly suitable for adjusting gapless live albums.

* Highly Configurable: Create groups to apply individual fine tuned settings to any specified subset of your songs.

* Awesome Usability: All the features above are fun and incredibly easy to use through a modern and clear user interface.

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.


Release Notes:

Compatibility with iTunes 12.2.

Review by Hulkss

iVolume, a must have for iTunes users - I can't believe I used iTunes without iVolume. Loudness leveling albums is much better than volume leveling individual tracks. Some songs are meant to be quieter than others on most albums. The program is fast and does a superior loudness analysis. You can fine tune the master volume to avoid +dB adjustments that may cause clipping. You can also group albums or tracks that you want to adjust with different settings. In my collection it took -16.4 dB of adjustment to loudness match a compressed CD like "System Of A Down" to a dynamic CD like "Dire Straights" even though both CD's peak at 0 dB. A great complement to iTunes. The program has worked perfectly.

a no go with .Wav - Paid $30 only to find out, when it ran, that this application does not support .wav music format, which half of my library is. Bummer…not worth $3 to me.

Version 3.7.5
Review by tristanian

Wow - This is possibly the greatest app i have ever downloaded, not joking. I have over 10,000 songs in my library, from hundreds of albums, and have been afraid to put my ipod on shuffle due ot the fact that 1 percent of the songs are really really loud! if i was running on the treadmill or lifting weights, i could serioulsy injure myself if one of the bad apple songs (high decible level songs) played in the music que. this app solves the problem perfectly, and apple should be embarrased that it took another developer to figure it out. hell, i would have payed 30 dollars to upgrade itunes. i love itunes. but its not a complete program without ivolume, no joke. My library is now complete with this app, and i am not afraid to put my ipod on shuffle and let all 10000+ go crazy.
