Widesound broadens the sound field produced by two closely-spaced speakers, resulting in a significantly wider stereophonic effect while still preserving the clarity of vocals and dialogue. Widesound is especially useful for presenting spatially-dynamic audio contents of games, movies, tv or live broadcasts. Widesound works even when speakers are extremely close together, e. G. , 2cm center-to-center for mobile phones. Widesound allows users to optimize the sound-widening effect for specific applications, from mobile phones to home tv. This is achieved by setting user-controllable parameters including the distance between speakers, distance from users to speakers, and desired widening angle. To illustrate the widesound effect: the small device shown in the picture below would normally produce a narrow-field sound, but with widesound, it would produce wide-field sound as if the audio signals were actually coming from the two wide-spaced speakers shown to the sides of the small device.
