OpenSound converts plain audio signals into immersive sound with elevated and wider sound field. With OpenSound, sounds coming from headphones pressed against the ears appear to come from virtual speakers away from the ears (out-of-head), creating a more open, 3-dimensional sound field (as shown by the spherical sound zone below).
OpenSound allows users to optimize sound perception effect through user-adjustable parameters for virtual speakers: open (widening) angle, elevation height and distance from the listener.
OpenSound applications include mobile phones, notebook/netbook PCs, stereo Bluetooth headsets, portable DVD players, game devices, MP3/MP4 players, learning devices, mobile TVs, and so on.
