Compatibility

• Supported Operating Systems: Supported OS: Mac, Windows
• RAM Requirements: License Method: Computer
• Disk Space: License Method: Computer at the cart page. System requirements: macOS 10.14 (x64, ARM), Windows 10 (x86, x64), OpenGL 3.2. Supported software formats: Standalone application, VST, AU, AAX (Pro Tools 11+) . Loudness Types One of the key features of this compressor is its support for a variety of loudness types. The compressor’s detection circuitry can be configured to use either LUFS or traditional measurement units (RMS, Peak). You can also choose to split or link channels, which is particularly useful for multi-channel audio formats such as Dolby Atmos® . The compressor’s detection circuitry can be configured to use any of the following loudness types: Momentary Momentary is a short duration LUFS measurement (400ms), which is useful for processing the audio’s moment-by-moment dynamics. This mode is responsive Note: Detector EQ affects detection only. The audible output is unchanged unless detector EQ monitor is enabled. Low-pass and high-pass filters with selectable slopes Parametric mid band with bell, shelf, or band-pass shapes Trim and mix controls for gain and blend Monitor modes to audition the detector path Back to top Limiter The compressor includes a built-in limiter which works seamlessly with the compressor’s attack/release ballistics. The limiter’s look-ahead setting is used to throttle the attack/release ballistics to prevent overshoots and can be configured to operate in Peak or True Peak mode. The same tab includes learned gain compensation for final-pass loudness correction. Choose Average or Integrated measurement, set the target, run a representative pass with Learn active, then Lock the result. The stored correction is added to the compressor result before the built-in limiter protects the configured output ceiling. Back to top Dynamic Types In additional to the unique “Source › Target” mode, the compressor also supports a variety of dynamic types. The compressor can be configured to operate as a traditional downward compressor, upward compressor, downward expander, upward expander, or soft limiting. These modes can be selected using the drop-down menu above the “Dry/Wet” dial. Back to top Credits above the “Dry/Wet” dial.

You can compress or expand directly within LUFS units, giving the compressor a response which is more perceptually natural and musically relevant. The primary feature which motivated starting APU Software and building the Loudness Compressor was to integrate LUFS directly into a compressor’s detection circuitry. The Loudness Compressor is my realization of that original goal, and it has evolved to include many more features since then.

This mode is responsive but also transparent, making it an appropriate default for the compressor. K-weighting and channel weighting are applied to the compressor’s detection circuitry, improving perceptual accuracy. Short-Term Short-Term is a longer duration LUFS measu
