Harddisko - audio techno art

Harddisko is an acoustic technological art project that uses defective hard drives to create fascinating rhythmic noises. "Special sound pickups" attached to the drive heads capture the audio signal while an electrical sequencer controls the hard drive's power-on initialization. Detailed information and sound clips about Harddisko can be found here:

Track "Schikaneder4.mp3" was loaded into the baudline time-frequency browser and the stereo spectrogram is displayed below. Clicks, blips, bleeps, head chatter, rich harmonics, and rotational power ramps are visible. It is music to my eyes!

The black bar on the right is caused by MP3 encoding only 16kHz of bandwidth. Notice the right purple channel in the final third of the orchestral piece.
