How to Tune Your Guitar Online

Tuning your guitar with our online guitar tuner is simple: click Start, grant microphone permission, then pluck each string near your device's microphone. The detected note appears in the central display, with a needle showing cents deviation from true pitch (displayed as ±0 cents at perfect tune).

Pitch Detection Algorithm

Our tuner combines autocorrelation (for fundamental pitch stability) with an FFT analyser (for fast updates) running entirely in your browser via the Web Audio API. The resulting ±1 cent accuracy matches pro clip-on tuners like the Boss TU-3 or Peterson StroboClip HD.

  • ✕ Background noise interference — use clean quiet environment.
  • ✕ Plucking string repeatedly too fast giving pitch meter no settle time.

Móvil y Táctil

Knowledge Base & FAQs

Frequently Asked Questions

Everything you need to know about our browser-based Web Audio engine, instruments, and music theory workspace.

How does the virtual guitar tuner work?

Our chromatic tuner uses Web Audio autocorrelation frequency detection to measure your instrument's pitch in Hertz (Hz) with sub-cent precision.

What is standard guitar tuning in Hz?

Standard 6-string guitar tuning is E2 (82.

41 Hz), A2 (110.00 Hz), D3 (146.83 Hz), G3 (196.00 Hz), B3 (246.94 Hz), and E4 (329.63 Hz).

How do I tune my guitar using this online tuner?

Pluck a string near your device microphone; the needle indicator displays whether your pitch is sharp (too high), flat (too low), or in tune (green).

What alternate guitar tunings are supported?

We support Standard, Drop D (DADGBE), Open G (DGDGBD), DADGAD, Half-Step Down (Eb), and Full-Step Down.

What pitch standard does the tuner use?

The tuner defaults to A440 concert pitch (A4 = 440.

00 Hz), the international standard for musical intonation.

Can I tune instruments other than guitar with this chromatic tuner?

Yes! It tunes bass guitar, ukulele, violin, banjo, cello, vocals, and any acoustic or electric instrument.

What does cents deviation mean in tuning?

A cent is 1/100th of a semitone; the tuner shows exact cents flat (-) or sharp (+) so you can tune with microtonal accuracy.

Is microphone audio recorded or sent to any server?

No, all audio processing occurs 100% locally inside your web browser with complete privacy.

Is this online guitar tuner free to use?

100% free with instant browser access on desktop, tablet, and mobile devices.

Why does my guitar go out of tune with temperature changes?

Wood expands or contracts with humidity and temperature shifts, altering string tension and pulling notes flat or sharp.
