Resonant ELF
An ELF radio feedback system by Absolute Value of Noise © 2010
Made for Art's Birthday January 17th, 2010

A creature of the season, Resonant Elf plays with radio feedback between two large magnetic coil antennas.

Resonant Elf uses a radio transmitter that operates in the ELF (extrememly low frequency) range. This corresponds with the frequencies of the audio spectrum - the range that the human ear can perceive (20 Hz to 20,000 Hz).

I have been working with ELF/VLF receivers for a few years (magnetic focus), using them to pickup ambient radiation in my studio, performance spaces, and various locations around Vancouver. The receivers pickup magnetic radiation given off by power-lines, transformers, and fold-down from higher frequency transmitters (radio transmitters, computers, monitors, cell phones, anything electronic).

For Resonant Elf, I built a feedback system between an ELF transmitter and the receiver, and tuned the receiver to collect 24 patterns of sound. The feedback becomes mixed with spurious noises from the electronic devices in the studio. The resulting sounds are then animated in software to produce an endless generative composition.
