yellow cedar


For a few years I have been experimenting with and building various sets of yellow cedar, red cedar, sitka spruce and maple flat audio-panels to create both instruments and audio diffusors that might engage in a more embodied form of listening and sound thinking. The LINKS below give an idea of the various explorations and implementation of these sound sculptures, and in general about the nature and spirit of these sound objects/instruments/resonators and my personal impetus behind them. You can find more informations in the West Coast Radians pagese HERE

The flat audio-panels are built using large boards reclaimed from discarded piles of wood in mill operations and drifting ocean logs on the Sunshine Coast of British Columbia. After being sliced and smoothly shaped, they are planed and sanded to thin them down to thickness ranging between 2/16”and 1/4” and finally mounted on a stabilizer wood stand.

An amplifier drives the sound into an audio transducer applied to the rear of each panel, exciting the wood boards and transforming their surface into a distributed-mode loudspeaker (DML). In this way the audio is approaching an omnidirectional presence in the way the sound from the panels is dispersed evenly in all directions.

The diffused radiation patterns of all frequencies created on the panels expands the audio source. Sound then propagates through the wood in the most liberated and natural way while becoming omnidirectional in the far field. The diffused sound is stunningly beautiful and softly filtered by the smooth quality of yellow and red cedar or the brighter resonating quality of maple and sitka spruce, which adds to the uncanny character of their physical and sculptural presence.


In January 2018 I presented this project at ECUAD part of Leaning Our of Window (LOoW)

In the Spring 2018 I presented an installation performance space at the Centre for Interactive Research on Sustainability (CIRS) at UBC with 16 panels driven by a 16-channel system. Both an installation and a performance instrument  were also made available to a variety of local sonic explorers during a three-day performance.

I’m currently working with wonderful musicians and friends Marina Hasselberg (cello) and Kenton Loewen (drums) to share the MAGIK beauty of the woods through a diffused space for sound thinking and imagination. A complete list of activities, places and collaborations is at the bottom of this page.
