Thanks for this. I ended up doing it very similarly except I used values of 0 and 20000 for my min and max items in the list to represent the range of audible frequencies. May not have made much difference but for some reason it's a lot louder in mine.
I see it, that was the same as @Jaymie harpex-imitation.vuo composition. The part that I am trying to wrap my head around is how to create many points or objects from the "calculate amplitude for frequencies" node output real list that are positioned around a sphere and then their individual placement on that sphere is adjusted according to their frequency and amplitude.
Kewl did you end up using ovals with copy layers or stick with Make Random Points Object?
It took me most of the afternoon but I was able to figure out a way to convert Calculate Amplitude for Frequencies real list data into a single integer as a "frequency variable" to adjust x or y parameters for a single 3D object. I am now trying to work in some more algorithmic approaches to generating points using parametric equations that can be affected by this frequency variable but it doesn't seem to be the most efficient way of going about it so if you have any tips that would be most appreciated.
