Record a few seconds of a voice you love. Nodalbloom turns its pitch into the pattern that sand makes on a vibrating plate. You keep it as a print and as a living page that plays the voice while the sand settles.
Your recording is analysed on your own device. Free preview, no account.
Press a voice to hear it and watch its pattern form.
Record on your phone or computer, or upload a clip you already have: vows, a first word, a message, a story told at the table.
The sound is split into its pitches. Each pitch picks a vibration pattern of a square plate, and the grains slide to the lines where the plate stays still.
Download a print file to hang on a wall, and a living page that plays the voice. Nothing is posted to you: it is yours at once.
Buyers of voice art usually have one recording in mind. These are the moments we built it for.
In the 1780s Ernst Chladni scattered sand on a metal plate and drew a violin bow along its edge. The sand jumped away from the parts that moved and gathered on the lines that stayed still. Those lines are called nodal lines.
Nodalbloom does this as mathematics. It measures the strongest pitches in your recording, gives each one a vibration pattern of an idealised square plate, and adds them up. The sand then settles on the lines of the combined pattern.
This is a computed pattern, not a photograph of real sand and not a scientific measurement of a person. A low voice gives a calm, wide pattern, a high voice a finer one. Different recordings gave different patterns in our tests; the same recording gives the same pattern again.
