Normalization (peak)

Peak normalization scales an entire recording so its loudest sample hits a target level — a uniform gain change that does not alter dynamics.

Peak normalizing makes files consistent at their maxima but not equally loud: a whisper with one loud clap normalizes to the clap. That is why loudness normalization (LUFS-based) replaced it for delivery.

What is Normalization?

Peak normalization scales an entire recording so its loudest sample hits a target level — a uniform gain change that does not alter dynamics.

Why does Normalization matter?

Peak normalizing makes files consistent at their maxima but not equally loud: a whisper with one loud clap normalizes to the clap. That is why loudness normalization (LUFS-based) replaced it for delivery.
