Peak normalization

Adjust the entire recording so its loudest sample reaches your target.

Every parameter, explained

Target peak

-12 dB to -1 dB · Default -1 dB

The highest sample level after processing, in dBFS. −1 dB leaves headroom; −6 dB gives a quieter peak. This changes all samples by the same gain.

A good place to start

Try the sample or upload a short recording. Apply the defaults, compare Original and Result, then adjust one parameter at a time. Revisions on this page start from your original recording.

What to listen for

Peak normalization preserves dynamics. It does not match perceived loudness between songs. Silence stays silent.

Compare a quiet passage and a busy passage at a comfortable listening volume. The player volume changes playback only; it does not change the downloaded audio.

Can I combine this with other effects?

Yes. Open the combination studio and choose this effect along with any others. Effects run in the displayed order, and completed stages are reused. Changing or removing an earlier effect rebuilds the affected stages.

Once processing finishes, compare the result and download MP3 or WAV. MP3 encoding runs locally and does not apply the effects again.
