Do you actually need a sine wave or would a square wave be suitable? I was
just thinking that 10 to 50kHz would be quite a sensible range of
frequencies to generate directly using the ( or at least a )
microcontroller. You could always make the edges nice and curvy later with a
couple of external parts.. hehe how about some old valves :)
