Another name for Dolby Digital sound.
Dolby Digital AC-3 is a flexible audio data compression technology capable of encoding a range of audio channel formats into a low rate bitstream. Eight channel configurations are supported, ranging from conventional mono or stereo to a surround format with six discrete channels (left, center, right, left surround, right surround and subwoofer). The AC-3 bitstream specification permits sample rates of either 48 kHz, 44.1 kHz, or 32 kHz, and supports data rates ranging from 32 kbps (kilobits-per-second) to 640 kbps.
The first name for the Dolby Digital sound format and comes from Audio Coding revision 3, the system used to encode and decode Dolby Digital soundtracks.
Also know as Dolby Digital 5.1
The 5.1-channel compressed digital sound system specified for DTV broadcasting in Canada. AC-3 delivers CD-quality digital audio and provides five full-bandwidth channels for front left, front right, center, surround left and surround right speakers, plus an LFE (low frequency effect) subwoofer, for a total of 5.1 channels. AC-3 is one member of a family of sound systems developed by Dolby Labs.
The original name for the encoding scheme now officially termed Dolby Digital. The AC-3 term still frequently appears in reference to descriptions of the process.
A term synonymous with Dolby Digital.
Dolby Digital (5.1) and AC-3 are different terminology for the same audio technology, which is the 6 channel sound system developed by Dolby Laboratories.
Audio Codec 3. The original name for the multi-channel effects developed by Dolby. Now generally referred to as Dolby Digital.
Dolby's digital-audio data compression algorithm. It is now the standard for HDTV broadcasts and is also used in DVDs.
An early name for Dolby Digital.
The original named used for Dolby Digital. The name was later changed to feature the Dolby name.
Adaptive transform coder 3. A lossy compression method used in Dolby Digital.
Digital Audio Compression - 3 ( website)
the original name for Dolby Digital (see below).
The first descriptor for what is now called Dolby Digital.
Dolbyâ€(tm)s third generation Audio Coding algorithm, also known as "Dolby Digital®." Itâ€(tm)s the multi-channel sound system specified as the standard for Digital HDTV. AC-3 delivers CD-quality digital audio and provides five full-bandwidth channels for front left, front right, center, surround left and surround right speakers, plus an LFE (low frequency effect) subwoofer, for a total of 5.1 channels.
An audio standard for delivering 5.1 audio developed by Dolby Laboratories. This system compresses six channels of digital audio into 384Kbps versus 4Mbps uncompressed.
The 5.1-channel sound system specified in the Standard for Digital-HDTV. Also known as "Dolby Digital," AC-3 delivers CD-quality digital audio and provides five full-bandwidth channels for front left, front right, center, surround left and surround right speakers, plus an LFE (low-frequency effect) subwoofer, for a total of 5.1 channels.
The multi-channel digital audio system developed by Dolby® and used by the new US DTV standard (also known as ATSC - Advanced Television Systems Committee). Also known as Dolby Digital®.
Dolby's trademark for digital sound system with either 2 or 5.1 channels. AC-3 multi-channel sound provides five completely separate (discrete) channels: Left, Center, Right, Left-Rear and Right-Rear, plus a common Subwoofer channel. The nominal digital bit rate is 384 kilobits per second.
The former name of Dolby Digital.
Dolby Digital AC-3, the digital audio format used for digital TV broadcasts in the United States.
Known to consumers as Dolby Digital, AC-3 is Dolby Laboratories' third generation of perceptual sub-band/transform codec. AC-3 is one of the mandated audio formats for both DVD-Video and ATSC Digital TV.
A.k.a. Dolby Digital. An audio compression scheme used in theaters, on laser discs, and in DVD movies.
A high quality multi-channel digital audio code developed by Dolby. Also known as Dolby Digital.
Is the former name for Dolby Digital.
A system for perceptually encoding at a reduced data rate both two-channel stereo and 5.1-channel surround sound. AC-3 has been developed by Dolby Laboratories; it is used in many motion-picture films and LaserDisc releases, and has been selected for television broadcast in the USA. mbisonics A method of recording and playing back directional sound over all horizontal directions, or the full sphere of directions including height, based on transmitting directional components of the sound field rather than loudspeaker feeds, and of reproducing the sound field by deriving signals psychoacoustically optimised for the user's specific loudspeaker layout.
Dolby Digital Surround Sound (5.1 Channels). See Dolby AC-3
Dolby Laboratories' new method of encoding full-range digital sound on film and consumer software and of decoding it for home theatre.
A data compression method, otherwise known as Dolby Digital, that uses psychoacoustic principles to reduce the number of bits required to represent the signal. Bit rates for 5.1 channels range from 320 kbps for sound on film to 384 kbps for digital television and up to 448 kbps for audio use on DVD. AC-3 is also what's known as a "Lossy" compressor (see Lossy Compression) that relies on psychoacoustic modeling of frequency and temporal masking effects to reduce bits by eliminating those parts of the signal thought to be inaudible. The bit rate reduction achieved at a nominal 384 kbps is about 10:1.
