Qu'est-ce que le mastering ?

Le mastering est la dernière étape avant de sortir un morceau. C'est la finition qui rend un mix abouti et cohérent partout : écouteurs, ordinateur, voiture ou sono de club. Un bon master fait trois choses : il équilibre le timbre pour que rien ne soit boomy ni agressif, il contrôle la dynamique pour que les passages doux et forts cohabitent, et il augmente le volume pour que votre titre tienne face aux sorties commerciales sur Spotify, Apple Music et YouTube.

Mixage vs mastering

Le mixage équilibre les pistes d'un morceau : voix, batterie, basse, synthés. Le mastering travaille sur le fichier stéréo terminé : timbre, dynamique, volume et largeur stéréo. On mixe pour que les éléments s'accordent ; on masterise pour que le morceau sonne bien partout.

Volume et true peak (LUFS, dBTP)

Spotify et YouTube ramènent la musique autour de −14 LUFS, Apple Music autour de −16 : un master beaucoup plus fort ne fait que perdre de la dynamique, puisque la plateforme le baisse de toute façon. L'autre chiffre clé est le true peak (dBTP) : garder un plafond de −1 dBTP évite l'écrêtage inter-échantillons ajouté par les codecs MP3/AAC et les téléphones. Spotify conseille −2 dBTP pour les masters plus forts que −14 LUFS. Loopin règle le volume selon le son choisi et garde le true peak sous ces plafonds.

Mastering gratuit et illimité, sans inscription

Aucun piège : titres illimités, re-masters illimités, pas de crédits, pas d'abonnement, pas de file d'attente et pas de compte. Masterisez le même morceau vingt fois avec des sons différents jusqu'à ce que l'un vous plaise ; rien n'est compté. Votre morceau reste privé : il n'est ni partagé ni conservé.

Quel son choisir ?

Beats — hip-hop, trap et électro

Commencez par Punchy (−11 LUFS) pour le hip-hop et la trap : il resserre les basses et affûte les attaques sans que le kick écrase tout le mix. Pour l'électro de club, Club (−10 LUFS) pousse le plus fort et élargit la stéréo en gardant la basse en mono. Si vous vendez ou publiez des beats, comparez Punchy et Club.

Voix — maquettes et auteurs-compositeurs

Pour un morceau centré sur la voix, Crisp (−14 LUFS) ajoute de l'air et du détail sans durcir les aigus, et Warm (−15 LUFS) arrondit le bas-médium si l'enregistrement sonne maigre. Masterisez toujours le mix stéréo, pas une piste de voix isolée.

Podcasts et voix parlée

Choisissez Cinematic, qui vise −16 LUFS, le niveau demandé par Apple Podcasts. Loopin est pensé pour la musique : montez et nivelez vos dialogues avant, c'est une étape de finition, pas de réparation.

MP3 ou WAV : quoi importer, quoi récupérer

Importez un MP3 ou un WAV (et la plupart des formats courants comme M4A, FLAC ou OGG) — le mix stéréo du morceau terminé. Un WAV donne un meilleur résultat qu'un MP3 : le mastering fait ressortir le détail, et un MP3 en a déjà perdu. Vous récupérez un WAV 16 bits avec dither, prêt pour Spotify, Apple Music, DistroKid ou SoundCloud.

Pour une grosse sortie commerciale, un ingénieur entend encore des choses qu'aucun outil automatique n'entend. Pour tout le reste — maquettes, singles, beat tapes, le titre que vous voulez sortir cette semaine — un master qui a juste le volume, le timbre et les crêtes fait toute la différence.
