Dolby Headphone

Dolby Headphone is a technology developed by Lake Technology (Australia), that later sold marketing rights to Dolby Laboratories, sometimes referred to as Mobile Surround, which creates a virtual surround sound environment in real-time using any set of two-channel stereo headphones. It takes as input either a 5.1 or a 7.1 channel signal, a Dolby Pro Logic II encoded 2 channel signal (from which 5 or 7 channels can be derived) or a stereo 2 channel signal. It sends as output a 2 channel stereo signal that includes audio cues intended to place the input channels in a simulated virtual soundstage.
