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-First Pitch Detection: How Online Tools Protect Your Data

When using an online pitch detector, one common question arises: Is my audio private?

With growing concerns about data security, this article explains how our pitch detection tools work, what data stays on your device, and why you can use them with full confidence.

On-Device Processing: No Audio Leaves Your Computer

Our Pitch Detector uses Web Audio APIs built into modern browsers. This means:

All sound processing happens locally in your browser.
No audio files are uploaded to any server.
Once you close the page, nothing is stored anywhere.

You get real-time accuracy without sacrificing privacy.

Why Online Tools Can Be Safer Than Apps

Unlike some mobile apps that collect usage or audio data, our browser-based tools:

Run instantly with no sign-up or personal information needed.
Use open-source libraries for transparency where possible.
Depend on standard browser permissions — you control mic access.

Learn how we handle transparency on our Accuracy Tests page.
