[maxmsp] How to create visual representations of sound?

Well, begin by making clear what you want to achieve, in terms of
functionality before thinking technical realization. When you mix in the
same level "density of events", "amplitude", and "fft", I am worried about
what you want to focus on.
Define the function you want to achieve first.
Then, indeed, Max/MSP/Jitter is a very good environment in which it is easy
to link graphics and sound. Jitter tutorials will give you some ideas. Study
tutorials 27 and 28, for instance.
