About

Flick a glass. Knock the table. Pluck a rubber band. That sound becomes a creature. Hibiki Atlas turns the things around you into a collection of sounds. Record for three seconds and the app measures fourteen numbers from what it heard — pitch, decay, harmonics, noisiness and more — then builds a slime whose shape and motion come straight from those numbers. No randomness is involved. The same sound always makes the same creature, and a different sound always makes a different one. What you see is a direct translation of what was measured. - Color is pitch. Lower sounds are red, and every octave moves the hue along - Bumps are harmonics. Pure sounds are round; rich ones grow lumpy - Bells and metal, whose partials sit off the whole numbers, grow lopsided bodies - Struck sounds shake when you poke them, and the shake lasts exactly as long as the ring - Sustained sounds breathe slowly, and voices with vibrato tremble at the surface Merge two specimens and the child inherits from both: pitch lands between the parents, and each harmonic is taken whole from whichever parent was stronger there. No randomness here either, so the same pair always produces the same child. Features: - Turn a three second recording into a measured specimen - Shape and motion derived from the measurements, never from chance - Merge two specimens into an in-between child - Keep the original recording and every measurement on your device - An ensemble that plays your collection back as a piece of music - A gacha of 100 reference sounds, drawn with coins you earn by recording No account is needed. Recordings, photos and measurements stay on your device, and the app never sends them anywhere. A one-time Pro purchase adds analysis graphs, removes ads, imports your own audio files, unlocks every ensemble style, and lets you choose how two specimens merge. Kitchens, parks, workshops, the walk to school. The world is made of things that ring.
