A pair of [env~] objects, one for the left and one for the right.

[fiddle~] is quick and easy for pitch detection, otherwise you can roll
your own with PD's fft object set.

Best to think about what parameters/aspects of the sound you want to
use, and how they relate to the visuals you create. Have a look at the
examples/tutorials that come with PMPD for some other sound
visualization ideas using physical modelling.
I happen to like oscilloscope/lissajous displays for their simplicity.
You might check some of the other threads on this list for hints on how
to do this. [Scope~] is a simple one, but I'm sure you could create more
interesting ones with Gem. The "Skrewel" instrument in Reaktor 5 has a
particularly nice one that I'd like to try to rebuild in PD someday...
