Dolby Digital Live allows you to connect a PC or game console to your home theater using a single connection and enjoy the benefits of high-quality surround sound while you play.
Dolby® Digital Live provides a better overall game experience by immersing you in 5.1-channel surround sound to match your game play.
Optimized for low-latency interactive applications, Dolby Digital Live is ideally suited for games because it does not introduce any perceptible delays between video and audio.
Dolby Digital Live transforms PC audio signals into Dolby Digital, the audio backbone for home networks. This enables playback in the millions of home theater systems equipped with Dolby Digital.
By using a single digital connection, Dolby Digital Live ensures the integrity of the audio signal and eliminates the confusion, hassle, and clutter of multiple analog and digital connections.
The best gaming experiences
make you feel like you're not merely playing the game but a part of the game. Dolby
Digital Live makes achieving this feeling easier than ever by enabling real-time
playback of game audio through a 5.1-channel home theater system. With Dolby
Digital Live, sounds surround you and the audio details of the game come to
Dolby Digital Live works
inside your PC or game console while you play, encoding the 5.1-channel audio in
the game's audio engine into a Dolby Digital output bitstream. This makes the
audio compatible with all Dolby Digital 5.1 playback systems, including A/V
receivers, home-theater-in-a-box (HTiB) systems, and integrated 5.1 speaker
systems. It also makes connecting your PC or game console to your home theater easy.
All you need is a single S/PDIF connector.
The real-time interactive
capabilities of Dolby Digital Live make it ideally suited for games. It reproduces
audio cues and effects that remain faithful to the game developer's sound
design, and it does so without introducing perceptible delays between the
action onscreen and the sound coming from your speakers.
Dolby Digital audio coding divides
the audio spectrum of each channel into narrow frequency bands optimized for the
frequency selectivity of human hearing. Coding noise can stay very close in
frequency to, and be masked by, the frequency components of the audio signal.
The Dolby Digital algorithm
analyzes how the available bits are distributed among channels from a common
bit pool. Channels with greater frequency content can demand more data than
sparsely occupied channels, for example, or strong sounds in one channel can provide
masking for noise in other channels.
Dolby Digital coding can
process at least 20-bit dynamic range digital audio signals over a frequency
range of 20 Hz to 20 kHz. (The Low-Frequency Effects [LFE channel] covers 20 to
120 Hz.) Sampling rates of 32, 44.1, and 48 kHz are supported. Data rates for
5.1 channels include the 448 kbps standard for DVD-Video.
Dolby Digital delivers up to 5.1 discrete channels of high-quality surround sound for digital television, DVDs, and online streaming.
Dolby Digital Live delivers interactive 5.1-channel surround sound to players by allowing them to easily connect their PCs and game consoles to their home theater systems. Supported in some of the top consoles, it enables more engaging and exciting game play for any home theater. Dolby Digital Live makes it practical for developers to create game audio with 5.1-channel immersion and directionality for the largest number of players possible worldwide.
