Berklee College of Music Seminar on Spatial Audio and Live Performance Systems Design (Excerpts)

I had the pleasure of visiting the EPD department at Berklee College of Music in October 2016 to demo my multichannel guitar system on their new 10.2 loudspeaker system. Here are a few video excerpts kindly recorded by one of the EPD students in the audience. Thanks to Michael Bierylo for the invitation and to …

Guest Lecture and Performance at Berklee College of Music, Boston

I will give a lecture on spatial audio and live performance systems design at Berklee College of Music in Boston next Friday / October 28, 2016 / 4:00 p.m. I will also perform 2 improvised works for multichannel guitar as part of an evening concert (6pm) in the Electronic Production and Design department’s 10.2 multichannel …

Virtual/Transposed Landscapes

I’m working on a virtual reality and spatial audio piece with Messrs. Cluett and Manzione as part of the Virtual/Transposed Landscapes exhibition at apexart in NYC. The opening reception is on March 23 from 6pm to 8pm. Thanks to Christopher Manzione for curating the show. On view: March 24 – May 14, 2016 Featuring work by: Seth Cluett John Craig Freeman Ricky …

New Pd Externals: [grambipan~] and [grambidec~]

[grambipan~] and [grambidec~] are two new (basic) ambisonic objects for Pd. They will form a large part of the new grambilib~ library I am finishing this semester, allowing a user to control angle and elevation using an audio-rate signal. They’re largely based on the rg.ambi~ abstractions from 2015. All objects are written in the C programming …

Sounds & Schemas: Moving Music Metaphors

The following videos demonstrate another set of developmental mapping strategies for spatial music performance, which exploit bodily-based metaphors (see Johnson 2007). This set of examples present moving sound objects (individuated audio for each guitar string) moving from the front of the performance space to the rear. As each object is passed to an audio effects …

Developing Mapping Strategies for Spatial Music Performance

All videos are decoded for stereo playback. Please use headphones. This video demonstrates the mapping of skeletal data using an Xbox Kinect, Synapse, and Pure Data, within a developing live performance system. The kinect data controls in-kind spatial flocking behaviors of the ‘boids’ algorithm. Mapping Strategies for Embodied Metaphors – Improvised Musical Examples This video …
