RMS (Root Mean Square) and LUFS
(Loudness Units relative to Full Scale) are both measures of the intensity of audio signals, but differ in their application and meaning. RMS is a statistical term that describes the effective voltage or current of an AC signal. It is commonly used to calculate the average power of an audio signal. LUFS is a unit of relative loudness used in the audio industry. It describes the average volume of an audio signal on a scale that takes into account the human hearing process and the sensitivity of human hearing. Unlike RMS values, which refer to the effective strength of a signal, LUFS values refer to the relative loudness of a signal compared to a reference value. In practice, LUFS values are often used to control the loudness of audio recordings and broadcasts across different platforms and devices to ensure consistent audibility.
