Loudness normalization estimate
Estimate fixed gain from measured integrated loudness and preview the resulting true peak.
Measured integrated loudness (LUFS): -70–0; Target integrated loudness (LUFS): -70–0; Measured maximum true peak (dBTP): -70–6

Gain = target LUFS − measured LUFS; projected true peak = measured maximum dBTP + gain. Enter integrated loudness for the whole programme and its maximum true peak, not momentary loudness or sample peak. Both loudness inputs support −70 to 0 LUFS; true peak supports −70 to +6 dBTP, including fractions. Positive gain raises the signal; a projected peak above 0 dBTP exceeds digital full scale. A delivery ceiling may be lower: check the specification yourself. This is a fixed linear-gain estimate, not limiting, compression, file processing, a loudness meter or a compliance test. Gating and later encoding/processing can affect results: remeasure the rendered file. The −16 LUFS example is not a platform recommendation. Display uses six decimals without intermediate rounding.
Methodology
How it works
Gain = target LUFS − measured LUFS; projected true peak = measured maximum dBTP + gain. Enter integrated loudness for the whole programme and its maximum true peak, not momentary loudness or sample peak.

Frequently asked questions
What if the projected peak exceeds the delivery ceiling?
The requested gain alone cannot satisfy both constraints. Choose a different target or evaluate dynamics processing separately, then remeasure. −20 to −16 LUFS requests +4 dB; a measured −5 dBTP peak becomes −1 dBTP under linear gain. The tool never applies a limiter.
