Drawing on parallel experience and interest in both electronic
reconnaissance and auditory perception I have taken a new approach to
acoustic signal processing by merging their similarities in ability to
interpret complex signal environments. This system extracts meaning
from the acoustic waveform by treating the acoustic waveform, not as an
entity, but with each individual halfwave as an elementary source of
information having dimensions of energy, space, and time, called the
Waveform Information Vector, or WIV. This approach allows sorting the
emissions from each source into streams of WIVs from which individual
sources may be selected for attention. Its hierarchical structure is
closely analogous to the acquisition and analysis of intelligence from
reconnaissance data. The model has been tested successfully in a
variety of experiments that replicate responses of human subjects. Of
particular interest in speech processing is the ability to extract
voice pitch, phonetic segmentation, and voiced/unvoice
