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 axisLine 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).
