Download this sound and play it through a spectrograph! The audio was generated through an interpolation process in which xy values were assigned to a photograph. The data was then interpolated as audio with varying frequency and amplitude according to color placement within that grid. (x = time, y = frequency.) The result is that you can listen to a picture of the San Francisco city skyline, or anything else for that matter.

You'll note that the image appears to be distorted within the spectrograph, this is because frequency is really a logarithmic value, thus the visual reproduction of the interpolated audio data will be squished.

  Sweetness, I didn't realize that was available. Thanks so much for pointing that out!

  This Freesound preview has a spectrogram display option : click on the icon between "stop" and "loop", the icon looks like a bar chart.
