Perceptual
Coding
Use
of psychoacoustic principles for the design of audio recording,
reproduction, and data reduction devices makes perfect sense.
Audio equipment is intended for interaction with humans, with
all their abilities and limitations of perception. Traditional
audio equipment attempts to produce or reproduce signals with
the utmost fidelity to the original. A more appropriately
directed, and often more efficient, goal is to achieve the
fidelity perceivable by humans. Basically, this means removing
sound we cannot hear and/or only reproducing sound we can
hear. This is the goal of perceptual coders.
Principles of Masking
It
is often difficult to hear one sound when a much louder sound
is present. This process seems intuitive, but on the psychoacoustic
and cognitive levels it becomes very complex. The term for
this process is masking, and it is probably the most researched
phenomenon in audition (Zwislocki 1978).

Radio
Digital
radio is the transmission and reception of sound which
has been processed using technology comparable to that
used in CD players. In short, a digital radio transmitter
processes sounds into patterns of numbers, or 'digits':
hence the name, 'digital radio'. At the listening end,
digital radio receivers provide a standard of sound quality
that is significantly better than conventional analog
radios, just as CDs sound better than LPs.

MIT
Media Lab
In its first decade, much of the Laboratory's
activity centered around abstracting electronic
content from its traditional physical
representations, helping create now-familiar
areas such as digital video and multimedia.
The success of this agenda is now leading
to a growing focus on how bits meet atoms:
how electronic information overlaps with
the everyday physical world. The Laboratory
pioneered collaboration between academia
and industry, and provides a unique environment
to explore basic research and applications,
without regard to traditional divisions
among disciplines.
