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.
