Adjust Gain!

As you most certainly know, not all tracks are equally loud. Therefore, custom mixes can vary wildly in loudness, requiring the listener to adjust the volume for every song (audio normalization).

iTunes solves this issue with its proprietary Sound Check, a mechanism that attempts to replay all songs with the same loudness. Another, non-proprietary approach to the problem is ReplayGain.

beaTunes allows you to perform the ReplayGain analysis and adjust the standardized, track-specific id3 tags as well as the proprietary iTunNORM tags used by iTunes. It does not however, change the actual gain, meaning the original audio data remains untouched. Adjusting the gain at playback time is left to your music player (in iTunes Sound Check needs to be enabled).

Here's how it works

That's it! Couldn't be any easier, right?


beaTunes has a lot more useful features to identify tracks, detect the key of your songs, keep your library in shape, browse your songs in new ways, analyze your music and help you to create interesting playlists.
