Pitch Correction Software
Correct the pitch of any song or recording in Hz — fix a track that is sharp or flat or retune it to 432 Hz, then correct the key, speed, reverb and bass in the Audio Studio.
KeyPitch is browser-based pitch correction software — there is nothing to install. Correct the overall pitch of a song, vocal, instrument or recording here in Hz, then open the Audio Studio to correct everything else: shift the key by exact semitones, fine-tune the pitch in Hz, change the speed, add reverb as a percentage, boost the bass and more. Preview it all for free and download your corrected track when you are happy.
Frequently Asked Questions
Everything you need to know about correcting the pitch, key, speed and sound of your audio.
Pitch correction software adjusts the pitch of a recording so it sits at the right tuning. KeyPitch corrects the overall pitch of a song, vocal or instrument track in fine Hz steps — bring a track that is slightly sharp or flat back into tune, retune it to a reference like 432 Hz or 442 Hz, or match it to other instruments. It corrects the pitch without changing the speed.
Upload your MP3, WAV, M4A or MP4 to KeyPitch, drag the Pitch (Hz) slider until the track is in tune, and preview the result. When it sounds right, click Download and it opens in the Audio Studio, where you can fine-tune the correction, export your file, or correct the key, speed, reverb and bass as well.
Not exactly. Auto-Tune-style plugins snap individual notes of a vocal onto a scale in real time. KeyPitch is global pitch correction software: it shifts the pitch of the whole track up or down together, which is what you want for retuning a recording, fixing a track that was recorded slightly out of tune, converting to 432 Hz or matching a song to another instrument. It corrects the tuning of the entire file at once rather than note by note.
Yes — that is exactly what the Hz slider is for. If a recording sits a few cents sharp or flat against your reference, nudge the Pitch (Hz) slider in fine steps until it locks into tune. Because the correction is in Hz, you can make tiny adjustments that bring a track back to standard 440 Hz, or to whatever pitch your other tracks are tuned to.
Yes. Set the Pitch (Hz) slider to your target reference — 432 Hz for a warmer, lower tuning, 440 Hz for the modern standard, or 442–444 Hz to match orchestras that tune higher. KeyPitch retunes the whole track to that reference instantly, correcting the pitch while keeping the tempo and length exactly the same.
The slider on this page corrects the pitch in Hz. Open the Audio Studio and you can correct everything: shift the key in exact semitones (up to ±12), fine-tune the pitch in Hz, change the speed without affecting the pitch, add reverb as a percentage, boost the bass, apply 8D audio and more. It is a complete browser correction suite — adjust one setting or stack several, preview, then export.
No. KeyPitch uses time-stretching (SoundTouch) so pitch and speed stay independent. When you correct the pitch, the song keeps the same tempo and duration — only the tuning moves. In the Audio Studio you can also correct the speed separately if you want the track faster or slower without touching the corrected pitch.
Yes. Upload a vocal take and use the Hz slider to correct its overall tuning — useful when a whole take was sung or recorded a little sharp or flat, or when you need it to match a backing track tuned to a different reference. For note-by-note correction you would reach for an Auto-Tune-style plugin, but for bringing an entire vocal into the right pitch, KeyPitch does it in seconds.
Yes. Install the free KeyPitch Chrome extension and it adds pitch and speed controls right on YouTube and YouTube Music. You can correct the pitch of any video live — by semitones or in fine steps — and change the speed, with no download or upload. It is ideal for retuning a backing track or play-along to match your instrument or voice on the fly.
KeyPitch accepts MP3, WAV, M4A and MP4 files up to 50 MB and 10 minutes. When you correct the pitch of an MP4 the video stays intact and only the audio is processed. From the Audio Studio you can export your corrected file as MP3 or WAV.
Yes — uploading a file, correcting its pitch and previewing the result is completely free, and the Chrome extension for YouTube is free too. You only pay when you download a finished file from the Audio Studio: pay per export, buy a discounted pack of exports, or take a subscription for unlimited downloads.
No. KeyPitch runs entirely in your browser, so there is no pitch correction software to download or install and nothing to set up. Open the page, upload your track, correct the pitch and you are done. The optional Chrome extension only adds live correction on YouTube and YouTube Music.
The slider on this page covers a fine range of about one semitone in each direction (roughly 415.3 Hz to 466.2 Hz around A4), which is plenty for correcting tuning and retuning to 432 or 442 Hz. If you need a bigger correction — transposing into another key — open the Audio Studio and shift by exact semitones, up to ±12.
Small corrections are virtually transparent. KeyPitch uses high-quality time-domain algorithms (SoundTouch) to keep artifacts to a minimum, so a corrected track sounds clean. For the best result, start from a high-quality source such as a WAV or a high-bitrate MP3.
Singers and vocal coaches retune backing tracks into a comfortable range, musicians correct recordings to match other instruments, producers fix samples that were recorded off-pitch, and content creators retune voiceovers and music. Anyone who needs a track in tune — at 440 Hz, 432 Hz or any reference — can correct it in seconds, no DAW required.
Desktop pitch correction software like a DAW plugin is powerful but heavy to install, learn and license. KeyPitch gives you the everyday corrections — pitch in Hz, key in semitones, speed, reverb, bass — instantly in your browser, plus a free Chrome extension to correct YouTube in real time. There is nothing to install, you preview for free, and you only pay to export the finished file.
