Dolby Headphone

Dolby Headphone is a 3D sound technology developed jointly by Dolby Laboratories and Lake Technology of Australia achieving surround sound with regular headphones.

Normally when using headphones all the sounds are sounded in the head, making it uncomfortable to listen with headphones for long periods of time. Dolby Headphone simulates speaker playback in a room and positions the sound sources to the front or the sides, outside of the head, achieving a powerful sound similar to that of a movie theater or home theater. This technology is aimed mainly at multi-channel audio or video equipment including Dolby Digital or Dolby Pro Logic Surround decoding functions and operates inside a high performance digital signal processing chip (DSP).

The Dolby Headphone mode can be used not only with multi-channel sources but also with stereo programs.
