Hi Alin,

Thanks for your message.  Have you had a chance to look at the audio tools in Firefly?  Specifically the Frequency Spectrum component (released in the latest version of Firefly)?  This outputs the full frequency spectrum (performing a Fast Fourier Transform on the incoming waveform) and returns a list of values.  It would be easy enough to turn those into a polyline (just feed those values into one of the component values of a list of points... say along the Z-axis... and use a range component to create a incremented list of values to feed into either the X or Y axis).  Then you can just extrude the line some distance to get a surface.  It should be relatively straightforward.  Have a look at that component and let me know if you have any other questions.

Cheers,

Andy
