APU Software APU Loudness Compressor v3.4.6 (Win/macOS)

The APU Loudness Compressor is a compressor/expander designed to support modern loudness types (LUFS, True Peak). This means the compression curve is a function of LUFS measurements instead of RMS or Peak. Since LUFS is a more accurate measure of loudness, the result is very transparent compression, making it particularly well suited for mastering and post-production workflows.
