Creates a graph of an audio waveform, where the height of the curve is determined by the amplitude of each audio sample.
Fill Color— The color of the area between the curve and the axis
Line Color— The color of the curve.
Amplitude— The curve’s maximum height, in pixels.
The output image’s width is 512 pixels (the size of a sample buffer), and its height is
2*Amplitude + 1 (the positive and negative extent of the curve, plus a pixel for the axis).
