Audio Visual, a project by Peter Crawley, shows us the waveforms of popular songs, neatly stitched on a piece of cardboard. Here we see a visual representation of Whole Lotta Love, with the waveform of one minute of audio on each line.
Next to these visualized waveforms Peter Crawley also creates stitched art themed around architecture and typography. Printed versions of his artwork can be found at Print Process.
