Guitar Tuner with Pitch Detection

  • Click to activate below, and then click 'Allow' in the window that appears
  • Tune each string until you see a bar for just the note itself and none of the surrounding notes.

Guitar Tuner Pitch Detection- technical matters

  • We're excited to offer this new Guitar Tuner with Pitch Detection. It is however a work in progress, and may not work with all devices
  • Although you can use our main Guitar Tuner on mobile devices, the pitch detecting tuner uses Flash so is not currently available on mobile. We hope to rectify this soon.
  • First ensure your microphone is plugged in, then ensure you have clicked 'Allow' when the message appears
  • Some browsers may also give a small alert near the top of the screen asking if you want to grant permission for the website to use your microphone
  • The browser it seems to work best in is Google Chrome
  • Getting your computer audio to work properly in the browser is notoriously tricky so we can't guarantee this detector will work with your set up just now
  • Give it a try and good luck!
