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.
