LUFS Gain Calculator
How many dB of gain do you need to hit a loudness target? Enter measured and target LUFS — get the exact gain and your new true-peak estimate.
Loudness in LUFS adds linearly with gain in dB: +1 dB of gain = +1 LU. The only thing that can break is your true-peak ceiling — if the projected peak exceeds −1 dBTP, insert a true-peak limiter instead of plain gain.
