Software Tonoscope (2024)

Beyond the "wow factor," the software tonoscope has serious real-world utility.

For programmers and researchers, the "Chladni" Python library (using NumPy and Matplotlib) lets you build your own software tonoscope. You can simulate circular, square, or even irregular membranes. Requires coding knowledge but offers unlimited customization. Price: Free (GitHub). Platform: Any (Python 3.x). software tonoscope

Producers use tonoscopes to "see" the texture of their mix. A muddy bass will look like a blurred, unstable blob. A clean, rich chord will look like a sharp, symmetrical mandala. By adjusting EQ, compression, and reverb while watching the tonoscope, you can aim for harmonic ratios that are visually pleasing—often a sign they are acoustically pleasing too.

These applications take your microphone input or audio files and overlay cymatic-like patterns onto video.

Most software tonoscopes emulate the Chladni patterns of a square or circular plate. The formula is derived from the wave equation for a vibrating membrane. In code, the amplitude of a pixel at coordinates (x,y) is a function of the sum of all input frequencies multiplied by the Bessel functions of the plate’s shape.
