Interactive Tuner
An experience shell for tuning an instrument by ear with realtime analysis, microphone selection, and visual response controls.
Bring the live signal into tune
Select an input device, start the live tuner, and use the note, frequency, needle, and cents readout to bring the signal onto the reference pitch.
Start the input you want to tune
- Choose the microphone or input device and start listening.
- Play one sustained note and wait for the detected note and frequency to settle.
- Adjust the instrument until the needle centers, then stop the input when finished.

From microphone input to a stable pitch
Choose the input device
The meter is meaningful only when the selected input is receiving a clean signal; check the input level before judging the needle.
Read note, frequency, and cents
Reference A and input inertia change the response, not the target pitch: use inertia for a steadier or faster display and A for a different calibration.
Tune one string slowly and watch the response
- Choose the microphone or input device and start listening.
- Play one sustained note and wait for the detected note and frequency to settle.
- Adjust the instrument until the needle centers, then stop the input when finished.
