APU Software APU Loudness Compressor v1.9.3-TCD

APU Software APU Loudness Compressor is a Windows compressor and expander built around loudness measurement rather than just conventional peak or RMS detection. It supports LUFS and True Peak, using a loudness-aware signal path to shape dynamics in a way that more closely reflects how listeners perceive level.

Instead of relying on the familiar threshold-and-ratio approach, you define source and target loudness ranges. The plugin then compresses or expands the audio as needed to move between those ranges. This gives hobby producers a different way to manage dynamics, with controls focused on the relationship between the incoming material and the intended result.

Learn mode can automatically set either the source or target range from the audio being played. That provides a practical initial setup, which you can refine by ear rather than starting with every setting manually.

APU Loudness Compressor suits producers who want to explore LUFS-based dynamics processing and an alternative to traditional compressor controls. It is particularly relevant when perceived loudness matters more than simply keeping signal peaks in check.
