by TN Video 2006
Audio waves shaped as visual media
Project
first exhibited in Gallery
Alkovi from 07.04.2006 to 30.04.2006.
Abstract
Visual
waves short movie is based on "what you hear is what you see" concept.
Sound waves, through TN LAB equipment, will be displayed on the screen
in black and white. From sine wave to polyphonic melody, the video
presents audio waves shaped as visual media.
Analogue
television video signal consists in synchronization messages and the
displayed information. The synchronization messages, both vertical and
horizontal, frame the actual visual signals seen on the TV screen. This
frame repeats itself following defined standard known in Europe as PAL.
Synchronization messages must be respected in order to generate any
proper video signals. Once the frame created, the visual information can
be manipulated. Waves appear on the screen as white on black background.
Stable waves can be recognized on the screen, complex waves generate
abstract moving black and white square patterns.
Production
TN LAB,
Tuulanauhat laboratory in short, designed video equipment to output
video signals from analogue input. The equipment designed is both
hardware and software. The hardware devices manage three parts. First
the analogue sound wave is converted in digital format, this information
is then processed in the microprocessor unit, and finally the data is
output through the video out unit. The software, written in assembly, is
located in the microprocessor memory and its main task is to generate
synchronization frames and process the output video signal.
Visual
waves video set up consists in the TN LAB devices, Panasonic WJ-AVE5
video mixer, Sony VCR, Salora home television, Panasonic mini-DV MX300,
frequency generator and 8 tracks Tascam audio mixer.
