Logo for DSEE

Make your music sound more natural

When an original music source is compressed, it loses the high-frequency elements that add detail and richness to a track. Our Digital Sound Enhancement Engine (DSEE) faithfully restores them to produce high-quality sound that’s closer to the original recording. [A] Restoration  [B] Fine sound restoration
