I once emulated the frequency modulation with an arduino and a cheap IR sensor.
I don't remember the resolution of the arduino/IR sensor, but I got pretty good results.
I translated the distance values into frequency values, and I remember I had to
stabelize the input, by taking avarages over the values. If you used two sensors
like this, I think you could make a nice theremin controller...
