FAQ
What does normalizing audio do?
Normalizing analyzes your audio's loudness and adjusts it to a consistent target, measured in LUFS, so it doesn't sound too quiet or too loud compared to other tracks.
Will normalizing fix audio that's too quiet?
Yes — normalizing raises audio that's below the target loudness, as long as there is enough headroom before it would clip.
Which audio formats are supported?
You can upload MP3, WAV, M4A, AAC, OGG or FLAC files. The normalized result is delivered as MP3.
Do I need special software?
No — normalization runs on the server. You only need a browser.
What output format do I get?
Your normalized audio is delivered as a downloadable MP3 file.
