Make Waveform Image (vuo.audio.image.waveform)

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).

Keywords: amplitudes, oscilloscope
