Today’s fascinating sound is another example of the conversion of digital imagery into sound and was submitted by Manchester based artist Nick Froud. Nick writes:
“I have been following your blog for months and have found it really inspiring. The software featured in your most recent entry is quite similar to a program I (very quickly) put together for an exhibition idea I have. My girlfriend produces photography based and nature and process, I wanted to adopt these ideas into sound that could accompany each of her pictures in a gallery.
The program I made converts an image directly into sound by scanning along each pixel and outputting a sample to a wave file based on an average of the red, green and blue channels. It also outputs the red green and blue channels as CC data in a MIDI file. In this way, I intend to create music entirely generated from an image but with human direction as to choices of effects to be controlled by MIDI data, layering of sounds etc. The sound generated are much noisier than in other sound / image conversion applications, but I think it gives a better feel of the texture of an image.”
