¿Qué es la masterización?

La masterización es el último paso antes de publicar una canción. Es el pulido que hace que una mezcla suene terminada y consistente en cualquier sitio: auriculares, portátil, coche o discoteca. Un buen máster hace tres cosas: equilibra el tono para que nada suene retumbante ni estridente, controla la dinámica para que las partes suaves y fuertes convivan, y sube el volumen para que tu tema se sostenga junto a los lanzamientos comerciales en Spotify, Apple Music y YouTube.

Mezcla vs masterización

La mezcla equilibra las pistas individuales de una canción: voz, batería, bajo, sintes. La masterización trabaja sobre el archivo estéreo terminado: tono, dinámica, volumen y anchura estéreo. Mezclas para que las partes encajen; masterizas para que la canción se traduzca bien en todas partes.

Volumen y pico real (LUFS, dBTP)

Spotify y YouTube ajustan la música a unos −14 LUFS y Apple Music a unos −16, así que un máster mucho más fuerte solo pierde dinámica: la plataforma lo baja de todos modos. El otro número importante es el pico real (dBTP): dejar un techo de −1 dBTP evita la distorsión entre muestras que añaden los códecs MP3/AAC y los móviles. Spotify recomienda −2 dBTP para másteres más fuertes que −14 LUFS. Loopin ajusta el volumen al estilo que elijas y mantiene el pico real por debajo de esos techos.

Masterización gratis e ilimitada, sin registro

Sin trampa: pistas ilimitadas, remasterizaciones ilimitadas, sin créditos, sin suscripción, sin cola y sin cuenta. Masteriza la misma canción veinte veces con estilos distintos hasta que una suene bien; nada se cuenta. Tu pista es privada: no se comparte y no se guarda.

Qué estilo elegir

Beats — hip hop, trap y electrónica

Empieza por Punchy (−11 LUFS) para hip hop y trap: aprieta los graves y marca el ataque sin que el bombo hunda toda la mezcla. Para electrónica de club, Club (−10 LUFS) empuja más fuerte y abre el estéreo manteniendo el bajo en mono. Si vendes o subes beats, compara Punchy y Club.

Voces — maquetas y cantautores

Para un tema centrado en la voz, Crisp (−14 LUFS) añade aire y detalle sin endurecer los agudos, y Warm (−15 LUFS) redondea los medios-graves si la grabación salió fina. Masteriza siempre la mezcla estéreo, no una pista de voz suelta.

Podcasts y voz hablada

Usa Cinematic, que apunta a −16 LUFS, el nivel que pide Apple Podcasts. Loopin está pensado para música, así que edita y nivela el diálogo antes: es un paso de acabado, no de reparación.

MP3 o WAV: qué subir y qué recibes

Sube un MP3 o un WAV (y la mayoría de formatos comunes como M4A, FLAC u OGG). Usa la mezcla estéreo de la canción terminada. Un WAV da mejor resultado que un MP3: la masterización saca detalle, y un MP3 ya ha perdido parte. Recibes un WAV de 16 bits con dither, listo para Spotify, Apple Music, DistroKid o SoundCloud.
