FAQs

Normalizing audio means that the loudest parts of an audio signal are set to a specific value.

For example, -18 dBFS (decibels relative to full scale).

This is done so that all the parts of the sound mix remain at equal volume levels.

You can use normalization when you’re mixing or editing your music, or during playback on your speakers.

If you’re mixing, it’s important to listen for any clipping that could occur in your mix. And normalize before it becomes too loud and needs excessive fixing.

Normalizing the audio essentially means balancing the volume of the track.

Audio normalizers are used for balancing out the volume of music, podcasts, or other audio recordings.
