Metron's pitch-pipe.
The pitch-pipe plays a tone you can use as a reference sound to tune your instrument. Select the desired octave and pitch name, and, if desired adjust the pitch by calibrating up or down the desired amount of Hertz (or cents, if you selected that preference in the settings pane). The base tone frequence is relative to A4 = 440Hz.
If you prefer German (B = H) or Latin (Do, Re Mi, etc.) note names, you can change this preference in the settings pane.
