Resona Audio iOS

Art filters for sound. Resona captures the sounds around you — a room, a street, rain on glass — and transforms them through six audio filters that strip, stretch, corrode, and scatter the familiar into something you’ve never heard before.

Each filter is a philosophy of transformation, not just an effect: Fossil exposes the harmonic skeleton, Ghost stretches moments into dissolving memories, Swarm scatters audio into a living cloud of granular particles. Every filter has tactile parameter controls, and every adjustment simultaneously changes both the audio processing and a real-time particle visualization — so you can see what you’re hearing transform.

Sounds are saved as a visual collection, with each version generating a unique thumbnail derived from the audio’s spectral content. The architecture is nondestructive — originals are never modified, and every transformation branches as a new version you can return to, adjust, or push further.
