iVolume solves the annoyance of adjusting individual song volumes with its software that ensures all songs play at the same level. Its calculation is based on human ear perception for each song in your iTunes music collection.

iVolume integrates seamlessly with iTunes on Mac and PC, as well as various devices such as iPod, iPhone, Apple TV, FrontRow, and AirTunes. It also supports most popular audio file formats like MP3, M4A/AAC, AIFF, and Apple Lossless, making it a truly versatile tool.
One of the major advantages of iVolume is its speed. It takes advantage of the latest technologies and fully utilizes every core of modern multiprocessor machines for optimal performance. Additionally, iVolume remembers all the results ever calculated, which means you can apply changed adjustment settings without re-analyzing your songs.
Another feature of iVolume is its ability to keep albums intact. Thanks to a sophisticated album detection algorithm, iVolume optionally adjusts albums as a whole to keep the intention of the artist. This method is particularly useful for adjusting gapless live albums.
iVolume is highly configurable, as you can create groups to apply individual fine-tuned settings to any specified subset of your songs. And last but not least, the software is incredibly easy to use through a modern and clear user interface, making all the features above fun to explore. Overall, if you want to make your music experience smoother and more enjoyable, iVolume is definitely worth trying out.
