Make every video equally loud: pick a target — −14 LUFS for YouTube and Spotify, −16 for podcasts, −23 for European TV, −24 for US TV — and a peak limit.

How it works
Loudness is measured with the ITU-R BS.1770 / EBU R128 method (K-weighting, gating), the same way TV stations and streaming services measure it. The gain needed to reach your target is applied, and a peak limiter keeps the true peak under the limit you choose. If the limiter changes the loudness, CompressLab re-measures and corrects the gain, so the result lands on target.
In our tests on 20 files — quiet, loud, peaky, mono and clipped — results were within ±0.4 LU of the target with true peak under the limit, checked independently with FFmpeg.

Questions
What does LUFS mean?
Loudness Units relative to Full Scale — a measure of perceived loudness. −14 LUFS is louder than −23 LUFS.
What loudness does YouTube use?
YouTube normalizes playback to about −14 LUFS, so mastering there avoids your video being turned down.
