APU Loudness Compressor v1.5.2 WiN

APU Loudness Compressor is a Windows dynamics processor that handles both compression and expansion using modern loudness measurements, including LUFS and True Peak. It is aimed at music producers who want to shape dynamic range with a system that relates more closely to perceived loudness than conventional peak- or RMS-only detection.

Rather than relying on the familiar threshold-and-ratio workflow, the plugin lets you define source and target loudness ranges. It then compresses or expands the signal as needed to move between those ranges. Loudness-based processing runs throughout the signal path, rather than serving only as a meter alongside a traditional compressor.

Real-time graphics show how the processing affects dynamic range, giving you visual feedback while you adjust the settings. For hobby producers working in FL Studio or Ableton Live on Windows, it offers an alternative approach to dynamics control when perceived loudness is the priority. Version 1.5.2 is supplied in VST3 and standalone formats, so it can be used inside a compatible host or separately.
