11:40 Byzantium in Bing: Live Virtual Acoustics Employing Free Software - Paper Presentation

(40 min) Fernando Lopez-Lezcano, Travis Skare, Wilson Michael, Jonathan Abel » Location: Hall i7 (main venue)
A Linux-based system for live auralization is described, and its use in recreating the reverberant acoustics of Hagia Sophia, Istanbul, for a Byzantine chant concert in the recently inaugurated Bing Concert Hall is detailed. The system employed 24 QSC full range loudspeakers and six subwoofers strategically placed about the hall, and used Countryman B2D hypercardioid microphones affixed to the singers' heads to provide dry, individual vocal signals. The vocals were processed by a custom-built Linux-based computer running Ardour2, jconvolver, jack, SuperCollider and Ambisonics among other free software to generate loudspeaker signals that, when imprinted with the acoustics of Bing, provided the wet portion of the Hagia Sophia simulation.

Day 2 - Friday, May/10 
20:00 Velvet Skin, Heart of Steel - Concert
 Fernando Lopez-Lezcano » Location: Mumuth
The newly inaugurated Bing Concert Hall at Stanford University may appear to be just sonic velvet, gracefully covered with multiple overlapping sinusoidal curves carved from warm resonant wood, its sails and cloud ceiling caressing all sounds produced on stage into enveloping beauty, but at the core, the Bing Concert Hall is made of steel. I had a chance to bang o n the steel beams as they were waiting on the ground before construction began. Sleeping steel, biding for its time of hidden glory. I also climbed on top of the “cloud” ceiling after construction wa s finished, recorder in hand, and spent one hour getting sounds out of anything that could be banged or scrapped or bowed. Some of those sounds are included in this collage and short etude that is a prelude for a longer piece. Included are metal doors banging in asymmetrical rhythms, steel pipes and beams of all shapes and sizes, big ventilation fans left over after construction, and much more. The sonic materials were coaxed into musical form using Bill Schottstaedt's s7 Scheme language interpreter and CLM.

The schedule is a major guideline. There is no guarantee events will take place at the announced timeslot.
