Draw a Waveform

The timbre of a tone is related to the shape of the repeating waveform.
To Do:

Draw in the box below and hear the result.
Hit the "Smooth" button and see and hear the result. The smoothing is done by averaging adjacent values together.
Draw a sine wave. Smooth it out. How low can you set the "Frequency" and still hear it well?
Add some spikes to the sine wave. How low can you set the "Frequency" now and still hear it?
