Autotune

Autotune para tu voz online — gratis, sin descargas

La herramienta de arriba es un editor completo de corrección de tono que funciona íntegramente en tu navegador. No hay nada que instalar, ningún plugin que configurar y ninguna cuenta que crear: suelta una grabación y la IA analiza tu voz y coloca cada nota cantada en una línea de tiempo de piano-roll, igual que los editores por notas como Melodyne.

Conviene saber que "autotune" abarca dos cosas distintas. Una es el efecto en tiempo real que fuerza la voz hacia una tonalidad — el sonido T-Pain. La otra es la edición correctiva tras la grabación, donde arreglas notas individuales manteniendo la interpretación humana. Esta herramienta está hecha para la segunda: tú decides cuánto se mueve cada nota, de modo que un estribillo ligeramente desafinado quede afinado sin que nadie note el procesado. (Si fuerzas los ajustes, también consigues el efecto robótico.)

Si eres nuevo en la corrección de tono, empieza con el botón de voz de muestra de arriba: puedes recorrer todo el flujo de edición en un minuto antes de grabar nada tuyo.

Todo se procesa localmente en tu navegador — tus archivos de audio nunca se suben a un servidor.

Cómo aplicar autotune a una voz en tu navegador: 5 pasos

1. Upload your vocalDrop in an MP3, WAV, FLAC, or M4A vocal recording. Nothing to download or install — everything runs in your browser.
2. Let the AI analyze itThe AI detects every sung note and lays it out on a piano-roll timeline with its pitch curve, so you can see exactly which notes are sharp or flat.
3. Edit note by noteDrag individual notes to retune at cent resolution, adjust vibrato and formants, fix drift — or snap everything to the detected key and scale in one click.
4. Preview AI Natural HQA/B the standard engine against the neural AI Natural HQ render on a free 15-second preview window — previews never cost credits, so you hear the difference before deciding.
5. ExportRender and download the tuned vocal as a WAV. Edits render in about a second, so you can audition as you go.

What people use it for

The most common use is tuning vocals for covers and "sing it yourself" videos — doing the pitch pass at home instead of paying a mixing engineer for it. But the same editor covers a lot of adjacent jobs: tightening a sung rap hook, fixing the melody line in a podcast jingle, making a songwriting demo listenable enough to share, or correcting each singer in an a cappella arrangement one track at a time. Anywhere one voice carries one melody, the piano-roll workflow applies.

And if you actually want the hard-tuned robotic sound as an effect, that works too: snap everything tightly to the scale with fast correction and no transition time, and you get the classic T-Pain / hyperpop character. The difference is that here it is a choice, not the only mode the tool has.

Pitch correction basics: cents, keys, and drift

A few terms make the editor much easier to understand. A cent is 1/100 of a semitone — most listeners start hearing "slightly off" at around 20–30 cents, which is why this editor lets you move notes at cent resolution instead of full semitones. Key and scale correction means snapping notes to the pitches that belong in the song’s key; the tool detects the key automatically, and one click tunes the whole take to it. Drift is when a held note slowly slides sharp or flat over its duration — note-based editing lets you flatten just the drift while keeping the natural slide into the note, which is a big part of why corrected vocals here can still sound human.

On the piano roll, every detected note sits at its nearest pitch with its full pitch curve drawn inside it. That means you can see which notes are sharp or flat and by how much, instead of hunting for them by ear — for beginners this is usually the moment pitch correction stops feeling like guesswork.

Recording a vocal that is easy to tune

How well any pitch editor works is mostly decided before you open it. Record the vocal dry — no reverb or delay baked in — because effects smear the pitch information the AI needs to find your notes. Keep one voice per file: doubled vocals or background harmonies in the same recording confuse note detection, since the analyzer is built for one melody at a time. And record in as quiet a room as you can; heavy background noise can register as extra "notes."

Format matters a little too: a WAV or FLAC export gives the cleanest analysis, though a decent-bitrate MP3 or even a phone voice memo works fine. If you are recording on a phone, hold it a steady distance from your mouth — level jumps between words make notes harder to detect cleanly.

Tips for pitch correction that does not sound processed

The biggest beginner mistake is correcting everything. A vocal sounds human because it drifts a little — if you snap every note perfectly to pitch, the take starts to sound synthetic. Fix the notes that are noticeably sharp or flat, leave the small movements alone, and be gentle with vibrato edits: flattening vibrato completely is what makes voices sound robotic.

Large pitch moves — say three semitones or more — are where any pitch-shifter starts to color the voice, because the timbre moves with the pitch. Keep formant preservation on, let the automatic portamento smooth the note boundaries, and audition extreme moves note by note; smaller, musical corrections will always sound more natural than dramatic jumps.

One more thing worth knowing: pitch and formants (the character or "size" of the voice) are edited separately here. Leave formants alone for normal correction so raised notes do not turn thin and chipmunk-like — and move them deliberately only when you want to change how the voice itself sounds.

One-click scale correction vs. editing notes by hand

A practical rule of thumb: start with the one-click correction when you just need the take in tune — a cover you are posting tonight, a demo you are checking against the instrumental. The tool detects the key, snaps the take to it in seconds, and you can then hand-fix only the notes that still bother you. Reserve full manual editing for material that matters most, like the lead vocal of a song you plan to release: deciding note by note how far each pitch moves is what keeps a chorus sounding sung rather than tuned.

The two modes are not either/or. The fastest real-world workflow is: one-click correction first, manual touch-ups on the handful of notes that stand out, then a full listen before export.

Un estudio de grabación online con auto-tune integrado

Esta página no es solo un plugin de afinación: forma parte de un estudio de grabación online completo. Puedes grabar tu voz directamente desde el micrófono en el navegador, afinarla con el editor de auto-tune de arriba, montarla sobre una base en la línea de tiempo multipista y terminar con masterización por IA — sin instalar nada.

Esto importa para el flujo de trabajo: una voz afinada casi nunca va sola. Con un clic la envías al editor como pista, añades el instrumental, generas armonías, ajustas niveles y exportas una canción terminada y masterizada — gratis y en el navegador.

Qué es gratis y qué cuesta dinero — con honestidad

Gratis y sin cuenta: detección de notas, edición de tono nota por nota, ajuste de vibrato y formantes, corrección automática de tonalidad y escucha ilimitada de tus ediciones. Exportar las ediciones a audio (Apply) requiere una cuenta gratuita y está limitado a una vez al día; Pro lo hace ilimitado y añade renders completos con armonías generadas. Ese es todo el muro de pago: no hay marca de agua ni cuenta atrás de prueba.
