With Dolby® Headphone technology, your customers will experience rich, dramatic surround sound over conventional headphones.
Delivers realistic 5.1-channel sound from any set of headphones
Provides a more comfortable listening experience, reducing listener fatigue
Enables superb surround sound from stereo music and movies when combined with Dolby Pro Logic® II
Dolby Headphone accurately creates the sensation of up to five loudspeakers in a room using powerful digital signal processing (DSP) technology. The result is a richer and more natural listening experience over conventional stereo headphones.
Dolby Headphone is compatible with native 5.1-channel content. When combined with Dolby Pro Logic II, Dolby Headphone can transform content from a two-channel source into a surround sound listening experience.
When reproducing a source that incorporates Dolby Pro Logic IIz preprocessing, Dolby Headphone provides a 7.1-channel surround sound experience.
Dolby Headphone electronically imparts the sonic signature of a corresponding speaker properly placed in a carefully defined acoustic environment to each audio channel (two on stereo programs, and up to five on surround programs). The subwoofer signal (the “.1” Low-Frequency Effects [LFE] channel) is mixed into the Left and Right channels in equal proportion.
All of this information is combined by the Dolby Headphone processor into two encoded channels that deliver the spatial properties of the original audio, with more natural sounds that actually seem to be “out-of-head.”
With Dolby Headphone technology, your customers will be able to enjoy a private listening experience over conventional headphones that delivers all of the excitement of realistic 5.1 surround sound.
Dolby Headphone is compatible with discrete 5.1-channel sources. When used together with Dolby Pro Logic II, it provides a surround sound listening experience from two-channel sources.
In addition, in conjunction with content preprocessed with Dolby Pro Logic IIz, Dolby Headphone can deliver a convincing 7.1-channel surround experience.
Dolby Headphone technology delivers surround sound through any pair of headphones. It can be included in almost any device that can process stereo or multichannel audio and has a headphone output.
The Dolby Headphone process can be embedded into DSP chips or implemented in software for use in home theater A/V receivers and preamp/processors, in digital TVs, and in PCs. Dolby Headphone also offers application-specific integrated circuit (ASIC) design for higher performance at less cost than a typical DSP solution.
From the outset Dolby Headphone technology was designed to encompass all possible audio formats. Conventional stereo, Dolby Surround, and 5.1-channel digital content can all be enhanced for headphone reproduction by the Dolby Headphone process. The result is a far more natural sound over any conventional wired or wireless stereo headset on all programs, from 5.1-channel DVDs to stereo MP3s.
