Variations on Veni Creator Spiritus
from Ambisonic Studio Hosted by Ambisonic Studio
This file uses binaural encoding: it is meant to be played back on headphones. Variations on Veni Creator Spiritus is a electroacoustic remix of Jean-Pierre Leguay's "Cinq versets sur Veni Creator", itself a suite of five variations on the well-known Gregorian hymn. In the 2001 original source recording, Patrick Wedd played on the Karl Wilhem organ of Christ Church Cathedral in Montreal, Canada. To put it succinctly, the original recording is pre-treated with granular synthesis and then transformed and spatialized in Ambisonic B-Format in realtime using stochastic controllers. Audio file preparation was done with sound editor TwistedWave, granular synthesizer Audio Ease Thonk and sound editor/mixer Steinberg Nuendo. The Audio Units plug-ins used for live performance and responsible for random routing, processing and spatialization were built with SonicBirth. The live performance is done in Plogue Bidule where the multichannel file playback and processing all come together. The 1st order B-Format file out of Bidule was converted to binaural in Nuendo using the Harpex-B decoder with the "Kemar 1" HRTF set and the "diffuse" EQ setting. Conversion to FLAC was done with XLD. A more detailed explanation is available here: http://www.radio.uqam.ca/ambisonic/music.html
