It’s fun. It is like a relaxing kaleidoscope. Doing simple voice vowels reveals it’s limitations. It’s more of a visual representation of what cymatic patterns look like in general, but testing side by side with other Chladni videos, it’s not the same as an actual Chladni plate vibrating loose material. But definitely worth the price.
I’d like to suggest that each sand grain leave a fading trace or fading memory of where it’s been, kind of like a blip on a radar screen. Also, find some way to add color. Assign color to the vibrating sections of the membrane instead of just dots where the membrane is not in motion.
This app is the beginning of a wonderful research instrument… For now, it is the only option for iPhone/iPad and the developer has taken a great step forward to advance awareness of this field. As we [re]learn our ancient history, mandalas and temple/cathedral artwork take on a whole new meaning. In the beginning was the word… Now, some feature requests: Audio file input to create images from prerecorded samples. 3Drendering! This is performed in the time domain and may resemble structures in spheroid and cylindrical modalities. Looking from the side, it should look like a DNA helix. This is not an accident, our DNA is a musical arrangement in direct, translatable format as displayed edge on with the circular view. (That’s what mandalas really are, an edge on view to visualize a frequency.) Color! In two modes, one for amplitude with customizable palates and the other mode to identify converging frequency nodes from diverging harmonic interference patterns. If not already employed, AirPlay support to project the images. A recording feature with the capability to capture still frames with metadata to indicate the audible frequencies and proportionate amplitudes at the moment of screen capture. Video playback for review and archival purposes. And now, something ambitious, augmented reality engine to reverse engineer cymatic images into audio. Perhaps an app for the new Apple AR goggles? These features can exponentially accelerate, our understanding of natures audio/visual world and our interaction with it. This could even have medical and structural engineering uses. Interesting story, I had a Commodore VIC20 that recorded BASIC programs into audio tones on a special cassette tape drive. What’s old is new again. Let’s build a colorful new future for humanity.
Just got the latest version. They say they fixed the iPhone X issue five months ago. Nothing in this app worked on mine. I am sure they will not refund, so I just wasted a $1.99. Buyer be aware. If I could leave no stars I would.
Chladni figures were geometric figures first discovered by Robert Hooke in 1680 and was researched and published by Ernst Chladni in 1787. These geometric figures are typically rendered on a rigid, vibrating membrane made from materials such as metal, plastic, glass, or bowl, covered with grains, like salt and sand, and changes shapes in response to different sounds that are transmitted by mediums such as speakers and actuators. The study of such phenomena is also known as cymatics. Chladni is able to simulate the phenomena digitally. A further 3 programs can be displayed by pressing and holding each of the 3 mode buttons.
