[ubuntu-in] a unix puzzle

[AlgoMantra]

if you try *$cat yes > /dev/audio*
you should hear what sounds like a sine wave,
but probably isn't a true sine. The reason why
this happens (and more tricks) are described
here:

What I would like to do is send intended streams
of sound data from a C script to /dev/audio and hear them.
So I am looking for a solution where a simple wave
can be generated. Anyone? You'd need to know
how exactly /dev/audio interprets data as amplitude.
That's the key.

Anyways, if you can produce a sine, you can produce
(theoretically) any sound in the universe using a bit
of additive fourier theory.
