Espiral is a mixed network of analog and digital elements. 'Concrete'
and analog sounds are transposed in an interactive digital domain
for sophisticated and unpredictable spatialization and processing.
A double bass lying down at the center of a room receives
vibrations coming from a speaker fed with unaudible sub-frequencies.
The speaker has a ping-pong ball over its membrane. This
will result in vibrations and resonances produced by the body of
the double bass that will be captured and processed. The sonic result
of such a captured and processed source will be then diffused in
the room by four independent speakers in order to reproduce
acoustically the random trajectories traced by the ping-pong
ball solicited by the speaker vibrations.
The final result for the listeners will be a continuum of sound
streams moving and crossing each other in the space reflecting
the trajectories defined by the ping-pong ball.
All this process will be generated simply by a sequence of sub-frequencies
physically transmitted by a speaker
lying over a double bass
