Resona Audio

Every sound leaves a shape. Capture the world around you and reshape it through six filters that strip, stretch, corrode, and transform it into something unfamiliar.

Resona Audio turns the sounds around you into something you've never heard before. Record the world — a room, a street, rain on a window, a conversation — then run it through filters that strip, stretch, corrode, and reshape the audio into something unfamiliar. Each filter comes with a real-time particle visualization driven by the sound itself, so you can see what you're hearing transform. SIX AUDIO FILTERS Fossil — Exposes the harmonic skeleton. Freezes sound in amber, leaving only the ringing bones behind. Ghost — Stretches moments into lingering memories. The sound drifts, fades, and dissolves into warm residue. Swarm — Scatters audio into a living cloud of particles. Dense, chaotic, and always moving. Rust — Corrodes the surface. Smooth sounds snap into jagged steps as resolution collapses and decay spreads. Tide — Reshapes audio into waves. Push and pull, ebb and swell, the sound becomes oceanic. Mirror — Folds the sound against itself. One half reflects the other, slightly out of step — familiar but unsettling. CAPTURE MODES Drift — Continuous recording. Walk through a space and let the sound evolve. Layer — Build up multiple passes of the same environment. Snapshot — A single brief moment, captured and frozen. WHAT MAKES IT DIFFERENT Every filter has three parameters you can adjust — and every parameter changes both the audio processing and the particle visualization simultaneously. Turn a knob and hear the sound shift while watching the particles respond. The connection between what you hear and what you see is immediate and direct. Each saved version generates a unique visual thumbnail derived from the audio's spectral content. Different sounds through the same filter look different. Your collection becomes a gallery of sound made visible. Share your creations as video clips — the particle visualization playing over the processed audio, exported as a ready-to-post MP4. NO MUSICAL EXPERIENCE NEEDED Resona is not a DAW or a synth. There's no timeline, no tracks, no MIDI. You press record, pick a filter, move some sliders, and save. The simplest interaction — capturing a sound and twisting it — produces something that looks and sounds like nothing else on your phone. Built for curiosity, not expertise.
