Know where you stand in the loudness wars
Every musician wants their tracks to stand out of the crowd in terms of loudness, yet at the same time, many records cause ear fatigue after a short time of listening. To know where you want to, and where you will stand in this loudness dichotomy, you need a precise tool that will show you how loud tracks really are.

Cannot be fooled

Designed for the conscientious musician
Additionally, the Loudness Meter features a precise peak meter which can be combined with the loudness meter to using the display mode button to show the average dynamic range of the music rather than the loudness level.
