Sound that makes interaction clear.
UX sound design for apps, software and connected devices.
I’m Nils Heine. I create purposeful sounds that help people understand what happens, recognise feedback and feel connected to a product. I work with product teams, UX designers and developers to give digital interactions a coherent sonic identity.

Every sound has a purpose.
From a subtle confirmation to an attention-worthy alert, I design audio around the meaning of each interaction. The aim: clear feedback, a consistent product voice and sound that earns its place.

A cohesive family of sounds for your product. Shared tonal character, consistent levels and clear variations across interactions help build a recognisable sonic identity.
Subtle sounds for taps, selections, transitions and completed actions. Feedback shaped around what an interaction means and when people need to hear it.
Distinct cues for notifications, confirmations and errors. Carefully balanced character, timing and intensity to communicate priority without unnecessary distraction.
My background in interactive audio and my work as Lead Audio Designer at GIANTS Software inform how I approach responsive feedback, timing and consistent sound behaviour.
