How accurate is the pitch detector?

Our tool is highly accurate, with a precision of within ±5 cents of a note. It uses the industry-standard YIN algorithm for reliable, real-time analysis suitable for both musicians and audio professionals. For more details, see our accuracy tests .

Is my audio data private and secure?

Absolutely. Your privacy is our top priority. All audio processing is done locally in your browser. No audio is ever recorded, stored, or sent to a server. You can read our full data security policy for more information.

The detector isn't working. What should I do?

First, ensure you have granted microphone access in your browser. If it's still not working, try using a quiet, echo-free environment and holding a clear, steady note. For a complete list of solutions, please visit our troubleshooting page .

What are 'cents' in music?

A 'cent' is a unit of measurement for musical intervals. There are 100 cents in one semitone (the distance between two adjacent notes on a piano). Our meter shows how many cents sharp (positive value) or flat (negative value) your note is, allowing for very precise tuning.

What is the difference between pitch and frequency?

Frequency is the scientific measurement of a sound wave's vibrations per second, measured in Hertz (Hz). Pitch is the musical term for how high or low a note sounds to our ears. While they are related, pitch is a subjective perception, whereas frequency is an objective measurement. Learn more in our glossary .

Can I use this to tune my guitar?

Yes! This tool works perfectly as an online guitar tuner. Simply play each string one at a time and use the feedback to adjust the tuning pegs until the note is perfect. It works for acoustic and electric guitars (if played through an amplifier).

Privacy & Security: How Audio-File Pitch Detection Works on Your Device

When analyzing audio recordings, privacy and data security are top concerns. Many musicians, teachers, and students worry about whether their recordings are uploaded or stored when using online tools.

The Audio-File Pitch Detector is designed with privacy first. This article explains exactly how it works, what happens to your files, and why it’s safe for personal and professional use.

On-Device Processing: No Uploads, No Storage

Unlike some online tools that send audio files to external servers, the Audio-File Pitch Detector works entirely in your browser.

All processing happens locally on your device.
No audio data is uploaded or stored anywhere.
When you close the browser, everything is gone — no history, no caching.

This approach ensures full data privacy for sensitive recordings like student lessons, choir practices, or studio sessions.

Why Privacy Matters for Musicians & Teachers

Student Lessons: Protect minors’ recordings under school or teaching policies.
Choir Rehearsals: Avoid sharing full-ensemble recordings unintentionally.
Professional Work: Keep studio takes and compositions private before release.

Browser-Based Security Features

Modern browsers use secure sandbox environments for web tools. This means:

The tool cannot access your files beyond the one you select.
Permissions are requested only for microphone or file access when needed.
You can revoke permissions anytime in browser settings.

Supported File Types
