Normalize Audio — questions fréquentes

What does peak normalize do?+

It finds the single loudest sample and scales the whole file so that peak sits at −1 dBFS — as loud as possible without clipping.

Peak normalize vs. adjust gain?+

Peak normalize is automatic and based on the file's own level. Adjust gain applies a fixed dB change you choose, up or down.

Is this loudness (LUFS) normalization?+

No — it's peak-based, which is simpler and safe. True LUFS loudness matching needs a heavier analysis pass.

Is my file uploaded?+

No. Analysis and processing run entirely in your browser.

Envoyez-vous mes fichiers sur un serveur ?+

Non — chaque outil ici traite vos fichiers entièrement sur votre appareil, et rien n'est envoyé à un serveur. La seule exception concerne les outils d'IA, qui envoient le texte extrait (pas le fichier) à Claude pour faire leur travail.

Y a-t-il une limite de taille de fichier ?+

Nous n'imposons aucune limite artificielle, mais comme le traitement se fait dans votre navigateur, les fichiers très volumineux (plus de 500 Mo ou 1000 pages) sont limités par la mémoire de votre appareil, pas par nous.
