iVolume 3.7.5

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 or when using the shuffle mode. 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.
