APU Software has introduced a new dynamics optimization tool designed to support modern loudness types (LUFS, True Peak).
Underneath the hood, the APU Dynamics Optimizer uses the same compression engine as the APU Loudness Compressor, but benefits from the full audio waveform instead of real-time measurements, allowing the gain envelope to be meticulously optimized across the entire waveform.
The design of this tool allows you to very precisely target a specific average LUFS and dynamic range. Once the gain envelope has been optimized, you can playback the result in real-time while adjusting the character of the sound with the same collection of parameters from the compressor plug-in.
A standalone application for Windows and Mac, APU Dynamics Optimizer is priced $40 USD. A bundle with the APU Loudness Compressor is $55 USD, and owners of the compressor and request a discount on the optimizer.
