Sound is visible.
A mathematical transformation that converts audio into images — and images back into audio. Not as a visualisation trick. As a lossless, reversible encoding of the sound itself.
Hover over any animation to enable audio.
What is this?
Sound has a fingerprint. We found a way to calculate it — and render it as an image.
The image is not an interpretation or an artistic visualisation. It is the sound. The entire texture, shape and feel of a sound — what makes a piano sound like a piano — is encoded in the pixels. Change the sound and the image changes. Change the image and the sound changes ! The transformation is lossless and reversible.
We call these images cyclograms — and for audio, timbres, because that is exactly what they show. Sunics shines a different light on sound, revealing details that escape the ears.
The technology works on any periodic signal like audio, ECGs, machine vibration.
Four reasons to keep reading.
Audio, health, engineering — and more.
See our early audio prototypes. But sound is just the start. The same technology applies to ECG waves and rotating machinery — anything that oscillates.

A collection of cyclograms — visual fingerprints for strings, synths, flutes, organs, a didgeridoo, and a fractal. Plus sounds synthesised from images.
See the gallery → TechnologyThe science behind the image.
How we model signals in the time-phase domain, what cyclograms are, and why this is fundamentally different from spectrograms or the Fourier transform.
Learn how → AboutThe whale song that proved the maths.
The origin story — a mathematical idea conceived in the Australian Outback, and the whale song that became the first sound ever visualised as a cyclogram.

Visualise and share.
Load a sound, calculate its cyclogram, and see how different instruments produce completely different visual patterns. Every texture is instantly visible.
Watch timbres evolve.
As a sound changes, its cyclogram evolves in real time. Watch the pattern shift as synth knobs are tweaked. See the change before you hear it.
