=== Audio Engineering ===
RMS is used in [[Audio engineer|audio engineering]] to measure signal volume, particularly in the case of audio processing. The alternative volume measurement is peak volume, in analog as the signal V<sub>pp</sub>, or in digital as the -dB peak below clipping given the encoding format. Signal RMS in this context is often used as the comparator signal for [[Compressor (audio signal processor)|compression]], which produces a "smoothing" effect in compression by responding more slowly to sharp transients like those on drums.<ref>{{Cite web |last=Lessons |first=Alex-Mixing |date=2019-09-23 |title=Peak vs RMS compression: The difference between Peak and RMS |url=https://www.mixinglessons.com/peak-vs-rms-compression/ |access-date=2025-04-07 |website=mixinglessons.com |language=en-GB}}</ref> RMS is also used as a [[Mastering (audio)|mastering]] metric to compare against other time average units such as [[LUFS|LUFs]].<ref>{{Cite web |last=Luthar |first=Margaret |date=June 12, 2024 |title=RMS levels defined: how to get consistent loudness levels in mastering |url=https://www.izotope.com/en/learn/rms-levels.html?srsltid=AfmBOooGSAJqXnQOsjQbXSHrtq3_gZaQ5ssxT-bKCbhxuT0HKR43nw9H |access-date=April 7, 2025 |website=izotope.com}}</ref>
