What does Fair Loudness do?

Fair Loudness matches playback level when comparing versions. It reduces the louder version without changing the source file.

Updated 2026-09-11 · published 2026-08-08

Turn on Fair Loudness to compare versions at a matched playback level using their measured loudness. The control is available in the engineer’s player and on the client review page.

A level difference can influence a quick comparison. Matching levels helps you assess changes to tone and dynamics, but does not decide which version is better.

Fair Loudness uses attenuation: it reduces the louder version rather than boosting the quieter one. It does not alter the stored file. The free A/B tool offers a comparison without an account.
