Artists are finishing songs with Loopin
Notes from producers, beatmakers and songwriters who sent us a message after mastering a track.
Loopin free mastering helped me hear my song as a finished track instead of another rough export. The vocals felt clearer, and the overall balance worked better on my headphones. Having online mastering available while I finish a release makes the process feel much less intimidating.
Maya BennettIndependent artistI make original background music for my YouTube videos, and Loopin mastering helped the track feel more consistent beside the rest of my edit. The simple upload process was a big plus. Free online mastering is helpful when I am working with a small budget.
Ethan KimYouTube creatorThe stereo image was the first thing I noticed on my electronic track. The synth layers felt easier to follow, while the main elements stayed focused. Loopin online mastering gave me a polished listening version without turning a quick test into a complicated studio task.
Owen MillerElectronic producerLoopin fits nicely into my daily production routine. I can check a master after finishing a mix and listen again with fresh ears. For an independent producer, having accessible online mastering makes it easier to keep moving instead of leaving every nearly finished track sitting in a folder.
Marcus ReedIndependent producerI tested Loopin mastering on a trap beat with a deep bass line and bright hats. The result felt tighter and easier to listen to. I still checked the low end carefully, but the free mastering workflow made sharing a polished preview much quicker.
Mateo RiveraTrap producerI liked how my dance track felt more cohesive after using Loopin. The kick, bass, and brighter layers sounded more connected in the version I downloaded. Online mastering for producers is especially useful when you want a quick comparison before making the final decisions on a mix.
Leila HaddadDance music producerI make short music pieces for videos, and Loopin free mastering helps me finish them with less friction. The audio felt more consistent on the track I tested. I appreciated having an online tool that let me spend more time on the actual creative work.
Riya KapoorContent creatorI used Loopin online mastering to check a track after several rounds of mixing. The stereo presentation felt more organised, and the overall sound was easier to assess. Having a quick mastering option helped me stop endlessly tweaking and start listening to the song as a whole.
Adrian ChenHome studio producer
I tried Loopin online mastering on a beat with heavy drums and a soft melody. The result felt more balanced without losing the groove I liked. For quick beat mastering before sharing an idea with an artist, this is a useful part of my workflow.
Jordan EllisBeatmakerI produce in a bedroom, so I like having another way to check how my mix comes across. Loopin online mastering made this track feel more cohesive. It did not replace getting the mix right, but it helped me feel more confident about the final export.
Arjun MehtaBedroom producerI am still learning music production, and mastering used to feel like a step I could not approach yet. Loopin free mastering made it easier to hear a finished version of my song. I appreciated the straightforward process and having something useful to compare with my original.
Sofia RamirezMusic hobbyistI used Loopin free online mastering on a pop demo with layered vocals. The result felt clearer and more connected, especially when the chorus arrived. I liked hearing the song with a more finished presentation before sending it to the people helping me with the release.
Lily BrooksPop artistAfter recording a cover at home, I wanted the final audio to feel a little more complete. Loopin free mastering helped bring the vocal and backing track together. The process was easy enough that I could focus on the performance instead of getting lost in extra settings.

Brianna HayesRapperMy lo fi beat needed polish, but I wanted to keep its softer character. The Loopin master felt smoother and more consistent without making the track feel overly aggressive. Free beat mastering like this is useful when I am testing ideas before choosing what to release.
Hana ParkLo fi beatmakerMy instrumental had quiet sections and a bigger ending, so I wanted a master that still felt musical. Loopin gave me a useful version that sounded more even overall. Online mastering helped me check the track as a complete piece rather than focusing on individual sounds.
Anika ShahInstrumental composerWe tried Loopin online mastering on a rehearsal recording we had cleaned up and mixed. It gave us a more consistent version to share with friends. For an independent band testing material, free mastering is a helpful way to hear how a song might come together.
Caleb FosterIndie band memberMy guitar instrumental sounded a little uneven before I tried Loopin mastering. The mastered version felt more settled, and the quieter details were easier to follow. It was a useful finishing step for a home recording that I wanted to share without booking a studio session.

¿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.
Loopin vs servicios de pago vs ingeniero
| Loopin Mastering | Servicios de masterización con IA | Ingeniero de mastering | |
|---|---|---|---|
| Precio | Gratis, ilimitado | Por pista o mensual | Por canción; los precios varían mucho |
| Cuenta | No | Sí | Sí |
| Tiempo | Segundos | Minutos | Días |
| Remasterizaciones | Ilimitadas | Normalmente limitadas | Rondas limitadas |
| Ideal para | Maquetas, singles, la mayoría de lanzamientos | Maquetas, singles | Lanzamientos comerciales |
Para un gran lanzamiento comercial, un ingeniero sigue oyendo cosas que ninguna herramienta automática oye. Para todo lo anterior —maquetas, singles, beat tapes, la canción que quieres subir esta semana— un máster que acierta en volumen, tono y picos marca la diferencia.
