Audio Waveform Art

On May 9th, 2013 I had the idea to create drawings using audio thumbnails. From a technical standpoint, an audio file is just a list of numbers, each corresponding to an amplitude and delivered at a specified rate. It would be easy enough to match these numbers to an image on a grid then generate a WAV file from them. I was able to test my idea with a simple Python script. Once I had a proof of concept I meticulously drew some silhouettes and made the gallery above.

The screen-shots are of an editor named Wavosaur. The audio files will not open in some programs due to odd sample rates. The following ZIP archive contains the source files and one folder named "dinos" which has a Python script and a vector image created with Inkscape.
