Your emails are welcome! As for a physical sound visualization, one exists already: see "Numerical simulation of Faraday waves" by L. Tuckerman. As usual, the dry technical paper glosses over the visual aspect of Faraday waves. Basically, if you create such a standing wave in a cup of tea (e.g. by shaking the table), you'd see its shape via reflections, similar to how we can see the surface of ocean waves via reflections of sun. However, if you could suspend the water surface, put a LED ring above (one of those used for professional photos) and take an extremely high quality photo to see all the reflections and refractions created by that LED ring, yo'd see a picture of remarkable complexity. It looks a lot like a 3D hologram. I've been trying to simulate this effect on GPU.
