I’ve been interested of the idea of using ‘natural’ noise in place of white noise for synthesis, for example using field recordings of the ocean/wind/rain, tape hiss etc. So I was just thinking about using Photosounder and pictures of the night sky to produce some sort of semi-random noise. Then I found this picture and it’s much more interesting, it’s of ‘stars and passing aircraft’, with ‘1 hour exposure at f/5.6 taken later that night. The Milky Way is rising over the mountains.’
After a bit of tweaking I really like how this turned out, it makes a perfect riser, and much more interesting than a white noise build up!
