Hi,
Below please find a set of images. By clicking on the image, the wav-file download will start or play. The quality is 22kHz 16-bit mono. The sound is generated by passing white pseudorandom noise through a so called FIR filter. The sine-frequency response of this filter is equal to the brightness value of the pixels in a column, where pixels at the top will produce high sine-frequency noise and pixels at the bottom will produce low sine-frequency noise. Each wav-file will repeat the sound four times.
A
sunny morning: A series of dark mountains at the lower half. Then a
sun rising just above the moutains at the almost left. Then a cloud
free sky. Then a dark tree at the right middle, covering from top to
bottom.
