Adaptive Dynamics Enhancement

Modern recordings are being mastered with more and more aggressive dynamic range compression in an attempt to generate content that is louder than previous releases. This can often lead to large discrepancies in perceived loudness between tracks that were mastered at different periods of recent history. A commonly proposed solution to this problem involves the use of loudness normalization. While such normalization techniques help to reduce discrepancies in loudness, they cannot resurrect dynamics that were removed due to extreme levels of dynamic range compression. This paper outlines a technique for restoring the dynamics of modern music by continuously monitoring transient signal behavior together with the associated dynamic range levels. When dynamic range compression is likely, transients are restored to levels that are more expected for the type of material being played.
