APU Software APU Loudness Compressor v3.5.0 (Win/macOS)
P2P/BTCR | Date: 2025.3 | Size: 57.3 MBThe 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.
By default, the compressor operates using a “source range” and “target range” in place of threshold + ratio controls. You can also enable the traditional threshold + ratio controls if you prefer. A drop-down menu located at the top-right of the compressor’s dynamics section allows switching between these modes of operation and others, such as expander, limiter, etc.
With “learn” mode enabled, the compressor will automatically adjust the source or target range to match the source material. This can be a great way to get started with the compressor and can be used as a starting point for further fine-tuning.
