What does LKFS mean?

Loudness, K-weighted, relative to Full Scale (LKFS) is a unit of measurement used to quantify the perceived loudness of audio signals. It incorporates the K-weighted frequency response, which is designed to mimic the frequency response of the human ear at moderate listening levels.
LKFS is used in audio processing and broadcasting to maintain uniform loudness levels across various audio programs and advertisements, especially in broadcasting where maintaining a consistent listening experience is crucial. It helps regulate loudness and prevent sudden volume changes that could disturb listeners, contributing to a smoother audio experience.

Note:
K-weighting is a type of frequency weighting used in audio measurements. It's designed to mimic the frequency response of the human ear at moderate listening levels. It emphasizes frequencies in the midrange while attenuating low and high frequencies.
