transparent
(foldoc) | transparent
1. Not visible, hidden; said of a system which
functions in a manner not evident to the user. For example,
the Domain Name System transparently resolves a {fully
qualified domain name} into an IP address without the
user being aware of it.
Compare this to what {Donald Norman
(http://atg.apple.com/Norman/)} calls "invisibility",
which he illustrates from the user's point of view:
"You use computers when you use many modern automobiles,
microwave ovens, games, CD players and calculators. You don't
notice the computer because you think of yourself as doing the
task, not as using the computer." ["The Design of Everyday
Things", New York, Doubleday, 1989, p. 185].
2. Fully defined, known, predictable; said of a
sub-system in which matters generally subject to volition or
stochastic state change have been chosen, measured, or
determined by the environment. Thus for transparent systems,
output is a known function of the inputs, and users can both
predict the behaviour and depend upon it.

referentially transparent
(foldoc) | referential transparency
referentially transparent
An expression E is referentially transparent if
any subexpression and its value (the result of evaluating it)
can be interchanged without changing the value of E. This is
not the case if the value of an expression depends on global
state which can change value. The most common example of
changing global state is assignment to a global variable. For
example, if y is a global variable in:
f(x)
return x+y;
g(z)
{
a = f(1);
y = y + z;
return a + f(1);
}
function g has the "side-effect" that it alters the value of
y. Since f's result depends on y, the two calls to f(1) will
return different results even though the argument is the same.
Thus f is not referentially transparent. Changing the order
of evaluation of the statements in g will change its result.
Pure functional languages achieve referential transparency
by forbidding assignment to global variables. Each
expression is a constant or a function application whose
evaluation has no side-effect, it only returns a value and
that value depends only on the definition of the function and
the values of its arguments.
We could make f above referentially transparent by passing in
y as an argument:
f(x, y) = x+y
Similarly, g would need to take y as an argument and return
its new value as part of the result:
g(z, y)
{
a = f(1, y);
y' = y+z;
return (a + f(1, y'), y');
}
Referentially transparent programs are more amenable to
formal methods and easier to reason about because the
meaning of an expression depends only on the meaning of its
subexpressions and not on the order of evaluation or
side-effects of other expressions.
We can stretch the concept of referential transparency to
include input and output if we consider the whole program to
be a function from its input to its output. The program as a
whole is referentially transparent because it will always
produce the same output when given the same input. This is
stretching the concept because the program's input may include
what the user types, the content of certain files or even the
time of day. If we do not consider global state like the
contents of files as input, then writing to a file and reading
what was written behaves just like assignment to a global
variable. However, if we must consider the state of the
universe as an input rather than global state then any
deterministic system would be referentially transparent!

transparent audio coding
(foldoc) | transparent audio coding
A lossy audio compression algorithm
is transparent if the original and decoded signal are
indistinguishable to the human ear. The bit rate depends on
the codec and the audio material. Some codecs (e.g. AAC,
MP3) are optimized for transparent coding at a low data
rate, others (e.g. VQF, MP3Pro, AAC+SBR, WMA) for
distinguisable but pleasant reproduction at lower bit rates.
Typical data rates in kbps for different codecs are:
MP1 288-320
MP2 224-256
MP3 160-224
MPEG-2 AAC 128-160
MPEG-4 AAC 112-144
MPEGplus 160-200
