Frequently asked questions
Normalization adjusts the volume of an audio file so the loudest peak reaches a target level (e.g. −1 dBFS). This makes audio consistently loud without clipping.
Normalize before uploading podcasts, videos, or any audio where volume consistency matters. It ensures listeners don't need to constantly adjust volume.
For podcasts and streaming: −1 dBFS to −3 dBFS. For broadcast: −16 LUFS integrated (use a LUFS meter for broadcast-grade normalization). For general use: −1 dBFS is a safe default.
