animate audio spectrum onto a sphere using animation nodes? So, I'm trying to make an audio visualizer by applying a frequency spectrum onto a sphere.
(1st attempt at a visualizer using displace noise maps and audio baked to f-curves https://www.dropbox.com/s/b1dpi0hqu8icffz/visualizer%20v1_clip.mp4)

so, I'm using Animation nodes 2.1 and Blender 2.79b

I've been able to replicate this fantastic tutorial: https://www.youtube.com/watch?v=8PkdH_GXpQE, but translating the method onto a sphere is proving difficult.

can't seem to figure out how to get the data to work with a sphere. trying to get a ring of vertices and have them scale outwards?

Can anyone offer any guidance or assistance?
thanks
I shall show how this can be done in 2.8, but the same applies for older versions. You just transform/multiply your transformations (In this case a circular distribution of matrices) with a scale matrix composed from the frequency bins on one vector component:
