Bird Song Spectrogram Surface¶
A real field recording's spectrogram rendered and animated as a deformable Surface-topology grid — a showcase of what TOPO_SURFACE alone can do with real audio data.

Try it: download this example below (or the full examples set), then open Bird_Song_Surface_Topology_Example/Bird_Song_Surface_Topology_Example_gv_node.csv — or just drag its folder onto the GlyphViz window. Press Space to start the animation.
A full write-up of this example is coming soon.
