1-Bit Music (2004-2005), a project by composer and artist Tristan Perich, probes the foundations of digital sound.
An electronic circuit is assembled inside a CD case with a headphone jack on the side. The device plays back 40 minutes of low-fi 1-bit electronic music—the lowest possible digital representation of audio. The Cantaloupe Music release of 1-Bit Music is no longer available, except as a limited art edition ($100).
Perich works with the same chips to create 1-Bit Video and his machine drawings, pen-on-paper drawings executed by machine that explore randomness and order.
