PLR Calculator (Peak-to-Loudness Ratio)
Compute PLR — true peak minus integrated loudness — the single best number for how dynamic your master really is.
After streaming normalization levels everyone to ≈−14 LUFS, PLR is what you actually hear: a PLR-14 master keeps 14 dB of transient life above its average level, while a PLR-7 master is a sausage at the same perceived volume. Mastering engineers increasingly mix to a PLR budget rather than a LUFS target.
