[sdiy] What is chaos?

[Paul Perry]

It is true that chaos functions follow deterministic rules,
and therefore cannot be called 'random'.
And so, a chaotic function generated by a digital computer
gives the same result each time......
but, in the analog world, this is not so.

Because, in the presence of noise - no matter how little -
a chaotic system will diverge radically from the 'noiseless'
predicted pattern. This is an essential property of a
chaotic system. Which has obvious relevance to e-music.

Most often, when 'music' is constructed from a chaotic
system, what is beign extracted is a random function
(well, an apparently random function) of the 1/F type.
