The APU Loudness Limiter is a real-time limiter designed to support multiple loudness types simultaneously. The limiter can be configured to use LUFS, True Peak, RMS, and/or Peak loudness types. This allows you to simultaneously target multiple requirements, such as a specific LUFS target and a specific True Peak target. The limiter’s internal ballistics are configurable to work with different loudness limiter settings.

Loudness Metering Options
One of the key features of this limiter is its support for various loudness metering types. The limiter’s detection circuit can be configured to use LUFS and/or traditional units of measurement (RMS, peak). You can also split or combine channels, which is especially useful for multi-channel audio formats such as Dolby Atmos®.

The limiter’s detection circuit can be configured to use any of the following loudness types:

Instantaneous
Instantaneous is a short-duration LUFS metering (400 ms), which is useful for processing the dynamics of the sound at any given moment. This mode is fast, yet transparent. The compressor detection circuit uses K-weighting and channel weighting, which improves perceptual accuracy.

Short-Term Measurement
Short-term LUFS measurement (3 seconds) is useful for processing large-scale audio dynamics. Due to its longer duration, this mode is less responsive than instantaneous measurement, but it can be useful for adjusting the overall picture of audio dynamics. K-weighting and channel weighting are applied in the same way as with instantaneous measurement.

Integrated
Integrated is a LUFS measurement of infinite duration. K-weighting and channel weighting are applied in the same way as with instantaneous measurement, as well as with relative and absolute loudness adjustments. This type of loudness measurement can be useful for continuously adjusting the integrated loudness of an audio to suit a specific purpose.

RMS
RMS loudness measurement types use a sliding time interval of 150 ms by default, which is configurable. RMS is a traditional loudness measurement that is a good first-order approximation of perceived loudness. This mode does not use K-weighting or channel weighting in the limiter detection circuit, giving it a more traditional character.

True Peak
True Peak loudness measurements are similar to traditional peak measurements, but are more accurate because they take into account peaks between samples. These measurements use a time interval equal to the specified block size (1 ms by default). This mode prevents clipping of peaks between samples, which can be useful in mastering.

Peak
Peak Loudness modes are a standard peaking scheme that operates over a time interval equal to the specified block size (1 ms by default). This is another traditional limiter-style measurement. Technically, this mode is even slightly more sensitive than True Peak, but it is less accurate because it doesn’t take into account peaks between samples.
