Online Vocal Pitch Correction for Producers and Singers
Vocal pitch correction
Use browser-based vocal pitch correction to tighten rough vocal takes, demo ideas and topline sketches before moving into a full DAW session.
Repitching vocals
Shift vocals up or down by semitones and cents for creative effects, alternate keys, doubles and quick reference mixes without sending audio to a server.
Harmony generation
Create simple backing vocal layers such as thirds, fifths and octaves. These harmonies are pitch-shift based in V1 and are intended for drafts and arrangement planning.
Browser-based audio processing
The tool decodes and renders audio with Web Audio APIs in the browser. This keeps the workflow fast and private for demos, backing vocals and creative vocal effects.
No upload workflow
Your source file stays on your device. The page does not upload audio, use a backend or call an external audio processing service.
Use cases
Good fits include topline checks, rough backing vocals, octave doubles, key experiments, vocal FX previews and quick draft exports for collaboration.
Technology
How Browser-Based Vocal Pitch Correction Works
Web Audio API
The browser decodes your file, analyzes frames and renders a processed WAV with Web Audio APIs and local JavaScript audio buffers.
Local processing
The audio stays on your device. Processing, preview and export happen inside the browser session without a backend upload.
Vocal tuning basics
The tool estimates dominant pitch in short frames, compares it to the selected key and scale, then applies a controlled correction amount.
Harmony generation
Harmony layers are created with simple pitch shifting and mix controls, useful for backing vocal drafts and arrangement decisions.
Creative vocal FX
Presets combine tuning speed, pitch offset, tone shaping and harmony spread for quick pop, trap, lo-fi, robot and octave effects.
Privacy advantages
Private browser processing is useful for unreleased demos, toplines and sensitive vocal ideas that should not leave your machine.
FAQ
Vocal Pitch Corrector FAQ
Can I tune vocals online?
Yes. Upload a supported audio file, choose a key and scale, then render an approximate corrected version locally in your browser.
Does this tool upload my audio?
No. The file is decoded, processed and exported in the browser. It is not sent to a server.
Does the tool upload my vocals?
No. Your vocals stay local to the browser, including analysis, preview rendering and WAV export.
Can I create vocal harmonies?
Yes. You can enable third up, fifth up, octave up and octave down harmony layers with independent volume controls.
Can I create harmony vocals?
Yes. The harmony generator creates simple shifted backing vocals and octave doubles for draft mixes.
Is this real-time pitch correction?
The preview UI includes live playback visualization, but the corrected audio is rendered locally before playback and export for stability.
Is this the same as Auto-Tune?
No. This is an approximate browser-based pitch tool for drafts and creative effects. Professional releases should still use a DAW or dedicated pitch correction software.
Can I export the corrected vocal?
Yes. The processed result can be exported as a WAV file named from the original file with a vocal-pitch-corrected suffix.
Can I export WAV?
Yes. The tool exports a browser-rendered WAV file after processing.
Is my audio private?
Yes. The tool does not use server uploads, tracking scripts or external audio processing APIs.
