During our research and experimentation many processes have been
transfered into the audio frequency range and recorded on magnetic
tape. Presented here are selected recordings, each one editted
into a composition of, what one could call, electronic music or
organized electronic sound.
The auditory display techniques applied during research and simulations
were performed by Ed Prism and John P. Flight. Composition supervising
was done by Mr. Carl Edda.
Graphic recordings have been editted and filed by Joline LeRovan.
The various voltage signals in a simulated system can be transfered
into both audio and sub-audio. Each voltage represents a coefficient,
initial condition, and stimulus-response parameter within the
total system, and is varying over time-space coordinates during
the process. The inter-relations of all voltages at specific time-space
frame intervals are of particular interest.
Our machine room contains a range of apparatus to assign the signals
for control or direct analog generation, processing, and computation
obtaining an ‘auditory display’ of the systems behavior.
This sonification assures scientific analysis to obtain non-material
components of information otherwise obscured and hided. That information
is the main research target of this vessel.
The reader is referred to papers published at log673, and the
ships reference library for research design and theoretical handling
of the subject matter.
Several auditory record files can be found in the following register:
Guidance System (Prism)
3- Multi-level signalling
and fading (Flight, Prism)
4- Circle Map (Edda, Flight)
5- Sampled-data system
(Edda, Flight, Prism)
recordings (Copyright log673) were subjected to digital computation
for presentation onto this current medium.
