As part of my residency at iSAW in Miami, I developed (with help from Mark Godfrey) Sound Microscope, a simple web application for iSAW's educational outreach programs which explores the inner lives of sounds. The pan-and-zoom interface lets students isolate small fragments in the time and frequency space of a looping sound file, focusing on the structural subtleties and details they might not notice when hearing the entire sound. You can try out Sound Microscope yourself at iSAW's web site.
