i so far only used the graphical environment of pd. But now i'm searching for ways how the graphics could react to sound. To things like:
- tempo change
[bonk~] for beat detection, [timer] to measure intervals between beats
- volume change
[env~] is usually used for this. [snapshot~] is also quite useful in certain situations.
- pan change
A pair of [env~] objects, one for the left and one for the right.
- spectrum change
[fiddle~] is quick and easy for pitch detection, otherwise you can roll your own with PD's fft object set.
can anybody send me some further info about how to analyse incoming sound?
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...
