The Tonoscope is a software tool that allows users to analyze and visualize the tonal characteristics of sounds. I couldn't find a specific paper that you might be referring to, but I can give you an overview of the Tonoscope and its applications.
The potential for software tonoscopes is vast. As developers explore more sophisticated physics simulations, we can expect visualizations that are even more realistic and responsive. The integration of 3D modeling will allow us to see cymatic patterns in three-dimensional space. New and more interactive virtual reality (VR) and augmented reality (AR) experiences will allow users to step inside and interact with the patterns created by their voice. The technology is also poised to become more accessible, providing a suite of powerful cymatic tools right on the devices we carry in our pockets. software tonoscope
