However, once done he has the other part licked. I'm sure the
fabrication of spheres with machine tools will make sound. He can just
record it.

Supply context, please. As far as I know, machine tools are needed to 
fabricate concentric spheres, but you can hardly expect them to be free.

Hi,

How do I generate, using free tools, a series of concentric spheres on
the time-frequency axis and produce a sound file from that?
