Autotune your vocals online — free, no downloadThe tool above is a full pitch-correction editor that runs entirely in your browser. There is nothing to install, no plugin to configure, and no account to create: drop in a recording, and the AI analyzes your voice and lays every sung note out on a piano-roll timeline, exactly the way note-based editors like Melodyne do.

It helps to know that "autotune" covers two different things. One is the real-time effect that snaps a live voice hard to a key — the T-Pain sound. The other is corrective pitch editing done after recording, where you fix individual notes while keeping the performance human. This tool is built for the second kind: you decide how far each note moves, so a slightly flat chorus can become in-tune without anyone hearing that it was processed. (Push the settings hard and you can still get the robotic effect if that is what you want.)

If you are new to pitch correction, start with the sample-voice button above — you can walk through the whole editing flow in about a minute before recording anything of your own.

Everything runs locally in your browser — your audio files are never uploaded to a server.

Edits render in about a second, so you can audition as you go.What people use it forThe 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 driftA 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 tuneHow 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 processedThe 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 handA 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.

What is free and what costs money — honestlyFree with no account: note detection, per-note pitch editing, vibrato and formant adjustment, one-click key/scale correction, and unlimited edit auditioning. Rendering your edits to audio (Apply) takes a free account and is limited to one per day; Pro makes applies unlimited and adds full renders with generated harmonies. That is the entire paywall — there is no watermark and no trial countdown.

How it compares to Melodyne, Auto-Tune, and other online toolsHere is an honest look at the established options. They are good tools — the differences that matter are price, installation, and whether you can edit individual notes.

Note detection, per-note pitch editing, vibrato and formant adjustment, and one-click scale correction are all free and unlimited. The neural AI Natural HQ engine is free to preview on any 15-second window, and you also get one full-length HQ render per day free (two with a free account); Pro or credits cover anything beyond that.

How is this different from Melodyne?The core idea is the same — note-based editing on a timeline — but Melodyne is paid software (from about $99) that you install as a plugin or standalone app. LA Studio runs in your browser for free and focuses on vocals and other monophonic recordings; it does not do the polyphonic chord editing found in Melodyne Editor and Studio.

Do my files get uploaded anywhere?No. Analysis, editing, and rendering all run locally in your browser — your recording never leaves your device.

Can I use the tuned vocal commercially?Yes. Your recording stays yours — exports have no watermark and LA Studio claims no rights over them, so you can release and monetize the result freely.

Does it work on mobile?It runs in modern mobile browsers, but analysis and rendering depend on your device’s power. For long recordings and detailed editing, a desktop browser like Chrome or Edge is the smoother experience.

What is AI Natural HQ?It is a neural-vocoder rendering mode that re-synthesizes the tuned vocal, so even large pitch moves keep a natural, human tone instead of turning robotic. You can A/B it against the standard engine on any 15-second window for free.

Can it generate harmonies?Yes — you can generate harmony lines from your lead vocal. Auditioning harmonies in the preview is free; full-length renders that include harmony are part of the Pro plan.

What audio formats are supported?You can upload MP3, WAV, FLAC, M4A, OGG, and most other common formats. The tuned vocal exports as a WAV.

Do I need an account?No — all the core editing works with no signup at all. Creating a free account simply raises your daily free AI Natural HQ renders from one to two.
