IDUN audio develops dynamic spatial audio (DSA) embedded software for headphones. The goal is to enable people to use their natural hearing and head movements when listening with headphones. Use cases range from listening to music, watching movies, playing games, enhancing phone calls, participating in online conferencing, etc. IDUN audio’s headphone software makes it possible to create sounds in space around the listener. The sounds are perceived as stationary at a distance to the listener and can even be attached to real objects. The signal processing is done inside the headphone, as opposed to on a smartphone or a computer, like competitors do. This allows for low-latency head tracking, ensuring high quality audio with pinpoint spatial accuracy.
