n. an aquatic
animal that traps and removes food particles from a current of water
passing through its body.
Join Carassius Auratus for a delightful excursion as it swims through
oceans of atmospheric sound. Navigating through waves of sound the fish
generates a turbulent symphony.
Filter Feeder is a multi-channel installation in which textures, dynamics
and motion of both sound and video are controlled by a fish. The creature
navigates through the electromagnetic spectrum drawing fragments of
sound into the physical environment.
Spectral Drift: The atmosphere is inhabited by not only a cacophony
of audible sound but also a dense stratum of radio frequencies that
endlessly transmit sonic content. As the fish drifts through its aquatic
environment it also swims through the frequency spectrum. Sonic content
and visual imagery are subsequently positioned in the space and manipulated
in relation to the creature’s activities. In a similar manner to
a filter feeder, the fish consumes audible frequencies as they pass
by, creating an ocean of spatialised sound. Scanning the air waves,
fragments of media, conversations, atmospheric noise and static are
all absorbed. The mundane nature of the common goldfish in a bowl belies
its considerable control over the surrounding environment. In the work,
the fish’s activity controls numerous environmental parameters
including the position of sounds in 3 dimensional space, the live acquisition
of sounds plucked from the radio spectrum, real time manipulation of
video content via color gradients, compositing and generated acoustic
spectral visualization. The creature’s activities create a physical
space that is continually in a dynamic state of change.
Technical
Information
The work was developed
primarily in the max/msp
software environment with live video processing achieved with the use
of nato modular.
The activities of the fish were captured via a video camera and this
signal was subsequently sent to a computer for motion tracking analysis
within nato. The x / y coordinates of the fish were distributed to several
computers on a 10/100 Mbit network via the osc protocol for a variety
data processing tasks. The current technical setup of the project utilised
4 Power Macintosh computers for motion track video analysis, realtime
audio manipulation, realtime video manipulation and acoustic spectral
analysis. This configuration is scalable depending on the particular
presentation scenario.
Audio data was processed and output as a 4 channel sound mix. The fishes
x / y coordinates controlled the location of the audio content within
the 4 speaker matrix. Sonic content was broadband radio frequency sound
trawled by the fish in conjunction with hydrophone recordings. Video
data was distributed around the environment via 4 video/data projectors.
This included real time compositing of the fish and live sound spectral
data as well as a variety of other realtime video manipulations.
Here is are screenshots of one of the software audio
and video processing engines.
