A sine wave audio generator that allows fine tuning of the frequency. The frequency may be entered numerically using the keypad, or dynamically adjusted using the sliders within a variety of ranges. This allows the accurate setting of the frequency, as well its interactive manipulation (e.g. for the demonstration of beating). For convenience the default frequency is set to 440Hz (that is, concert pitch).
