Frequently asked questions
How is this different from raising the volume?
Raising volume multiplies everything equally (and can clip). Normalizing measures perceived loudness and brings it to a standard level without exceeding the peak ceiling.
What level is applied?
−16 LUFS integrated with a real peak ceiling of −1.5 dB: the sweet spot for voice and podcasts, compatible with music.
Good for several episodes?
Yes: normalize each file and they will all end up at the same perceived loudness.
