About TheGuitarTuner
We believe every musician deserves access to professional-grade tuning tools — free, instant, and beautiful.
Our Story
TheGuitarTuner.com was born from a simple frustration: why should guitarists have to download clunky apps or carry around expensive hardware just to tune their instrument?
We're a small team of musicians and developers who set out to create the most accurate, beautiful, and easy-to-use online guitar tuner. Using cutting-edge Web Audio API technology, our tuner provides real-time pitch detection with the precision you'd expect from professional equipment.
How It Works
Our tuner uses advanced digital signal processing algorithms to analyze the audio from your microphone in real-time. Here's what makes it special:
- Autocorrelation Pitch Detection — A sophisticated algorithm that accurately identifies the fundamental frequency of your guitar string, filtering out harmonics and noise.
- Real-Time Analysis — Processes audio data 60 times per second for instant feedback as you tune.
- Chromatic Mode — Detects any note across all octaves, making it perfect for alternate tunings or other instruments.
- Reference Tones — Built-in reference tones for standard guitar tuning, perfect for training your ear or tuning in noisy environments.
Our Commitment
TheGuitarTuner.com will always be:
- Free — No subscriptions, no premium tiers, no ads interrupting your practice.
- Private — We don't record or store your audio. Everything happens locally in your browser.
- Fast — No app downloads, no accounts required. Just visit and start tuning.
- Beautiful — Because musicians deserve tools that inspire, not frustrate.
