Overview
SoundCheck, an audio normalization feature available in iTunes and Apple Music, automatically adjusts the volume of songs in your library to a consistent level. This eliminates the need to manually adjust the volume between tracks, ensuring a smoother and more enjoyable listening experience. By analyzing the average loudness of each song, SoundCheck applies a gain adjustment to bring all tracks to a similar perceived volume. SoundCheck operates in the background, analyzing and adjusting volume levels without requiring user intervention, making it ideal for casual listeners and music enthusiasts who value a seamless listening experience. It is designed to work with both local music files and streaming content within the Apple ecosystem.
