Frequently Asked Questions

How does the browser-based tuner detect pitch?โ–ผ

The tuner uses your microphone to capture audio and applies auto-correlation pitch detection algorithms to identify the fundamental frequency of the sound. This is processed entirely in your browser using the Web Audio API โ€” no audio data is sent to any server.

Can I tune instruments other than guitar, ukulele, and bass?โ–ผ

The presets are designed for guitar, ukulele, and bass standard tunings, but the tuner detects any pitch. You can use it for other instruments by comparing the detected frequency against your target note. Any instrument producing a clear, sustained tone can be tuned with this tool.

Why does the tuner show inaccurate results?โ–ผ

Background noise is the most common cause of inaccurate readings. Tune in a quiet room, play one string at a time, and hold the instrument close to your microphone. Ensure no other apps are using the microphone. Low-quality built-in microphones may also reduce accuracy โ€” an external microphone can help.
