about

Maybe roughly 15 years ago I made a CD for my sister, taking some images from a website and mapping them into sounds. The process loaded an image, then created an oscillator for each row, then worked left to right using the colour of the pixels in the row to control that oscillator (for example, use the Hue of the colour to control the frequency, Saturation as amplitude, Value as stereo position etc.). I've rewritten that process in javascript for this project, which is not the fastest, but it does allow adding lambdas to do additional mapping.

The 'strips' in the album artwork are effectively the inputs to each track. Source code, image and mapping available here: github.com/van-appears/pngsound, should you prefer to generate or alter the output yourself.
