If you are looking to explore digital tonoscopes, several platforms and projects provide these capabilities:
A is a specialized computer program that utilizes digital signal processing (DSP) algorithms to visualize sound waves in real-time. By digitizing the traditional physical apparatus used in the field of cymatics , these software tools allow users to see the intricate geometric patterns created by sound vibrations without the need for physical metal plates or sand. The Origins: From Physical to Digital
The transition to software has opened up new possibilities for researchers, artists, and therapists.
