Model-Based Inversion of Dynamic Range Compression
Reversing dynamic range compression is a hot topic. Both Dolby and DTS offer research-based solutions, but they introduce artifacts and don't truly reverse the effect. Our approach is based on a mathematical breakthrough in the determination of how to invert a nonlinear, time varying system. It fully and accurately restores the original dynamics, and can add dynamics to a track regardless of whether it had been compressed. Advantages over existing approaches, include minimal computation, ease of implementation, real-time application, and avoidance of artifacts. An international patent has been filed (Gorlow and Reiss, 4/4/2013), and we are pursuing exploitation.
