Guitar Tuner

Graphical guitar and musical instrument tuner

GuitarTuner helps us procrastinators at least sound good when we take breaks from actual coding work.

The user selects a target note from a pulldown menu (includes E, A, D, G, B, E) or, for alternate tuning, manually enters a frequency. For audible tuning, the user may click the green arrow button to generate the target tone through the computer speakers. Click the red circle to start the graphical display, which uses your computer microphone or audio input jack to determine the tonal accuracy of each string. The display indicates when a string has been tuned to within 10 centitone of the target note.
