It's a topic that's been fascinating me for a while. Sounds, speech and music "produce" images in some sense, so visualizing sound on a flat screen is a meaningful thing to do. That parallel with the Heisenberg principle is a deep observation, I think. A few random thoughts. Colors correspond to notes: a clear red is like a clear "do" note. Volume is like size of the shape. Repetitive patterns correspond to symmetry. And that observation that there's no such thing as a "moment" if sound, and it's always about the past few seconds of sound that make it look like a music. I think this corresponds to multiple image layers with exponential decay: a sound pattern of past would look like a faint decaying background image that eventually disappears. I wish I could study this topic full time, but in our society you either make money or work on interesting things: the heinsenberg principle gas influence even here.
