APU响度限制器是一种实时限制器，旨在同时支持多种响度类型。可以将限制器配置为使用LUFS、真峰值、RMS和/或峰值响度类型。这允许您同时设定多个要求，例如特定的LUFS目标和特定的True Peak目标。在内部，限制器的弹道学被调整以适应不同的响度类型限制器设置。

响亮的味道
这种限制器的一个关键特征是它支持各种响度类型。限制器的检测电路可以配置为使用LUFS和/或传统测量单位（RMS、Peak）。您还可以选择分割或链接通道，这对于多通道audio格式（如Dolby Atmos®）特别有用。

限制器的检测电路可以配置为使用以下任何响度类型：

瞬间
瞬时是LUFS测量的一个短持续时间（400ms），可用于处理audoi的逐矩动力学。此模式响应迅速，但也是透明的。K-weiqhtinq和通道weiqhtin q应用于压缩机的检测电路，提高了感知精度。

短期的
短期是一个持续时间较长的LUFS测量（3秒），可用于处理audoi的大尺度动力学。考虑到较长的持续时间，这种模式的响应性不如瞬时模式，但它可以用于调整audoi动力学的双Q图像。K-weiqhtinq和通道weiqhtin q被应用于audiolove.me瞬时。

互联
Inteqrated是LUFS测量的无限持续时间。K-weiqhtinq和channel weiqhtiniq分别应用于audiolove.me瞬时和相对绝对qatinq的复制。这种响度类型可用于持续地将audoi的智能响度推向特定目标。

均方根
RMS响度类型默认使用150ms的滚动时间间隔，可以调整。RMS是一种传统的响度测量方法，它是感知响度的一阶近似值。该模式不将K-weiqhtinq或通道weiqhtin q应用于限幅器的检测电路，这是一个更传统的特征。

真实峰值
真峰值响度类型类似于传统的峰值测量，但由于考虑了样本间的峰值，它们更准确。这些测量使用与已确认块大小相等的时间间隔（默认为1ms）。此模式可防止剪切采样间峰值，这对主采样很有用。

高峰
峰值响度类型是一个标准的峰值电路，其工作时间间隔与配置的块大小相等（默认为1ms）。这是另一种传统的限制器式测量。从技术上讲，这种模式甚至比True Peak的响应更灵敏，但由于它没有考虑样本间的峰值，因此准确性较低。

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 target multiple requirements simultaneously, such as a specific LUFS target and a specific True Peak target. Internally, the ballistics of the limiter are adjusted to accommodate the different loudness type limiter settings.

Loudness flavors
One of the key features of this limiter is its support for a variety of loudness types. The limiter’s detection circuitry can be configured to use either LUFS and/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 limiter’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 but also transparent. 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 measurement (3 seconds), which is useful for processing the audio’s large scale dynamics. Given the longer duration, this mode is less responsive than momentary, but it can be useful for adjusting the bigger picture of the audio’s dynamics. K-weighting and channel weighting are applied as with momentary.

Integrated
Integrated is an infinite duration LUFS measurement. K-weighting and channel weighting are applied as with momentary, as well as both relative and absolute gating. This loudness type can be useful for continuously wrangling the audio’s integrated loudness toward a specific target.

RMS
RMS loudness types use a rolling time interval of 150ms by default, which can be adjusted. RMS is a traditional loudness measurement, which is a good first-order approximation of perceived loudness. This mode doesn’t apply K-weighting or channel weighting to the limiter’s detection circuitry, giving it a more traditional character.

True Peak
True Peak loudness types are similar to traditional peak measurements, but they are more accurate as they take into consideration inter-sample peaks. These measurements use a time interval equal to the configured block size (1ms by default). This mode prevents clipping inter-sample peaks, which can be useful for mastering.

Peak
Peak loudness types are a standard peak circuit, operating on a time interval equal to the configured block size (1ms by default). This is another traditional limiter style measurement. Technically, this mode is even slightly more responsive than True Peak, but it is less accurate as it doesn’t take into consideration inter-sample peaks.
