// This test generate synthetic data. For audio it's a sinusoid waveform with
// frequency kSoundFrequency and different amplitudes. For video it's a pattern
// that is shifting by one pixel per frame, each pixels neighbors right and down
// is this pixels value +1, since the pixel value is 8 bit it will wrap
// frequently within the image. Visually this will create diagonally color bands
// that moves across the screen
