The Audio Signal Generator app displays shows frequency and their relative levels. The app can not show you also the absolute level because not the variables in the sound system are known.
The frequency knob responds to mouse dragging. It is possible to twirl it using the mouse. The fine frequency and level sliders allow for fine adjustments of frequency and output level.
The frequency knob is also adjustable using the left and right arrow keys. The fine frequency slider is adjustable using the up and down arrow heys, the level slider using the page up and down keys.
Note: The Audio Signal Generator is cross-platform and it works both on Windows and Mac OS X.
