Guitar Auto Tuner
For best results, please tune in a quiet environment.
A guitar tuner helps you adjust the pitch of your guitar strings so they sound perfectly in tune. Pluck a string, and the dial will show you if the note is too high (sharp) or too low (flat).
Frequently Asked Questions
How does this online tuner work?
It uses the Web Audio API to capture sound from your device's microphone. Our advanced pitch detection algorithm analyzes the sound waves in real-time to determine the exact frequency and musical note of your guitar string.
Is my audio recorded or sent to a server?
No. The audio processing happens 100% locally within your browser. We do not record, store, or transmit any audio data to our servers. Your privacy is completely secure.
Can I tune other instruments besides a guitar?
Yes! While the presets are designed for standard E tuning on a guitar (E, A, D, G, B, e), the Auto-detect mode will identify any musical note. You can use it for ukulele, bass, violin, or even vocals.
Why is the tuner struggling to detect the pitch?
Make sure you are in a relatively quiet environment. Pluck the string clearly and let it ring out. If there is too much background noise, try using the manual string buttons to restrict the tuner to a specific frequency range.
