The Online Pitch Changer and the other tools and guides on this site are free resources for practice, learning and creative work. Tool results are estimates, not guarantees; guides are educational, not professional advice; and the site has no ads, no affiliate links and no ties to YouTube, Google or any music company.
Tool results are estimates
Pitch shifting, key detection, tempo changes and vocal range tests all rely on signal processing. The result depends on the recording and on your setup: its quality and compression, background noise, how many instruments play at once, your microphone, and your browser and device.
Calculators and charts, such as the semitone calculator, the music key chart and the chord transposer, follow fixed music-theory rules, so correct input gives an exact answer. Detection and processing tools give estimates. Use their results for practice, rehearsal, learning and creative projects, and check them by ear before you rely on them for a performance or a release.
How the tools work and the results we measured when testing them are on How it works.
Audio quality
Every pitch or tempo change alters the sound. The larger the change, the more audible artefacts usually become, such as a thin, metallic or “chipmunk” tone, and busy mixes show them sooner than a single voice or instrument. Browser tools are not a substitute for professional mastering or studio processing.
The tools do not change your original file. The result is a new file that you choose to download, so keep your originals.
Vocal range and voice type results
The Vocal Range Test and the voice type results are a practice guide. A voice type depends on more than your lowest and highest notes: tessitura (where your voice is comfortable), timbre and the points where your voice changes register matter too. Treat a result as a starting point, not a formal classification by a voice teacher.
Singer vocal range articles
Published ranges for well-known singers differ between sources and recordings. A single extreme note in one recording is not the range a singer uses every day. How these pages are researched and checked is described in the Editorial Guidelines.
Voice health
Nothing on this site is medical advice. Stop any vocal exercise that hurts. If you have lasting hoarseness, pain when singing or loss of voice, see a doctor or a qualified voice specialist.
Guides are educational
The guides explain music theory and show how to change pitch or key in apps such as Audacity, GarageBand, Premiere Pro and Final Cut Pro. App menus change between versions; if a step does not match what you see, check the app’s current official manual. The guides are not legal, medical or professional audio-engineering advice.
Copyright is your responsibility
A tool can process any file you give it, but that does not give you the right to use the file. Only process and share audio and video you own or have permission to use. The full rules, including the warranty and liability terms that apply to the whole site, are in the Terms and Conditions.
No affiliation
OnlinePitchChanger.com is independently run by Mayer. It is not affiliated with, endorsed by or sponsored by YouTube, Google, Spotify, Apple, Adobe, the Audacity project, any record label or music publisher, or any artist named on the site. Product, company and artist names are used only to describe them.
The YouTube Pitch Changer plays videos in YouTube’s own embedded player. It does not download, record or save YouTube videos or their sound.
No ads, no affiliate links, no sponsored content
The site shows no advertising, contains no affiliate links, publishes no sponsored content and sells nothing. No company pays to be mentioned or recommended on any page. If that ever changes, this page and the Privacy Policy will be updated first, and any paid link will be labelled as such.
External links
Some pages link to official sources such as software manuals and standards. We do not control those sites and are not responsible for their content, availability or privacy practices. A link is there because the source is useful, not because we have a relationship with it.
