A screen capture of a Northern Cardinal chirp, using the new Claude version of our real time sheet music app, is shown here. Can a human really imitate that? What other interesting sounds might be fun to create visualizations for?

To explore Fourier phase relationships, stay tuned for work underway using electronic sounds, like square, triangle & half wave snippets. Downstream, it may also be fun to show that we can replay the sound, from the picture!

Bull frogs (not shown) are lower in frequency, so many of those shown at left are likely tree frogs from across the world. As in the case of the Cardinal, they look almost like hieroglyphics. They might, moreover, retain similarities from chirp to chirp, and may even be useful in distinguishing individuals if we (like their frog peers?) could actually hear all the details that we can see with this app.
