Concert pitch changes the reference used to calculate every target note. Lower-frequency detection may need a longer, sustained note and a quiet environment.

Audio setup, tuning guide & FAQ

Choose your audio input

Built-in microphone: simplest for acoustic guitar, ukulele and room tuning. Put the mic near the instrument and reduce background noise.

USB audio interface: recommended for electric guitar and bass. Connect to an instrument / Hi-Z input, select the interface above, and set a clean input gain.

Driver & browser permissions

On macOS, select the interface in the browser input list. Install the manufacturer's driver/control app if the device requires one; many class-compliant interfaces work without a separate driver.
On Windows, install the manufacturer's ASIO driver for DAW use. Browser microphone access generally uses the system audio driver, not a selectable ASIO driver.
Allow microphone access for this site. GitHub Pages uses HTTPS, which is required for microphone capture.

Getting the best reading

Mute other instruments and play one string at a time.
Use a clean, sustained note; pluck firmly, then let the note settle.
For bass, give the tuner a moment to detect the low fundamental.
For electric instruments, direct interface input usually gives the cleanest result.
