Sine oscillator in Yampa

Yampa can be used to produce sound waves as illustrated here. In order to understand Yampa better I tried out the sine oscillator.

oscSine :: Double -> SF Double Double
oscSine f0 = proc cv -> do
               let f = f0 * (2 ** cv)
               phi <- integral -< 2 * 3.1415 * f
               returnA -< sin phi

sinTest = constant 0 >>> oscSine 1

embed sinTest (0.0, take 250 (repeat (0.01, Nothing)))

Plotting the result yields:

Ok. No problem so far.
