Surround Dolby Digital 5.1 Channel Mp3 Malayalam



when your computer has 5.1 channel speakers connected or connects via HDMI to a 5.1 or better surround sound AVR or home theater system. Note that many browsers and media players (particularly on mobile devices such as the iPhone) will output a stereo downmix from these streams, even if they don't support multichannel output.

DTS, on the other hand, offered two separate 6.1 versions. DTS-ES Discrete and DTS-ES Matrix perform as their names suggest. With ES Discrete, specific sound information is programmed onto a DVD or Blu-ray disc, while DTS-ES Matrix uses the same technique as Dolby Digital EX to extrapolate information from the surround channels.


Batman Returns was the first film to be announced as using Dolby SR-D (Spectral Recording-Digital) technology when it premiered in theaters in the summer of 1992.[7] Dolby Digital cinema soundtracks are optically recorded on a 35 mm release print using sequential data blocks placed between every perforation hole on the sound track side of the film. A constant bit rate of 320 kbit/s is used. A charge-coupled device (CCD) scanner in the image projector picks up a scanned video image of this area, and a processor correlates the image area and extracts the digital data as an AC-3 bitstream. The data is then decoded into a 5.1 channel audio source. All film prints with Dolby Digital data also have Dolby Stereo analogue soundtracks using Dolby SR noise reduction and such prints are known as Dolby SR-D prints. The analogue soundtrack provides a fall-back option in case of damage to the data area or failure of the digital decoding; it also provides compatibility with projectors not equipped with digital soundheads. Almost all current release cinema prints are of this type and may also include SDDS data and a timecode track to synchronize CD-ROMs carrying DTS soundtracks.


Dolby Digital EX is similar in practice to Dolby's earlier Pro Logic format, which utilized matrix technology to add a center surround channel and single rear surround channel to stereo soundtracks. EX adds an extension to the standard 5.1 channel Dolby Digital codec in the form of matrixed rear channels, creating 6.1 or 7.1 channel output.


It provides an economical and backwards-compatible means for 5.1 soundtracks to carry a sixth, center back surround channel for improved localization of effects. The extra surround channel is matrix encoded onto the discrete left surround and right surround channels of the 5.1 mix, much like the front center channel on Dolby Pro Logic encoded stereo soundtracks. The result can be played without loss of information on standard 5.1 systems, or played in 6.1 or 7.1 on systems with Surround EX decoding and added speakers. A number of DVDs have a Dolby Digital Surround EX audio option.


Dolby Digital Live (DDL) is a real-time encoding technology for interactive media such as video games. It converts any audio signals on a PC or game console into a 5.1-channel 16-bit/48 kHz Dolby Digital format at 640 kbit/s and transports it via a single S/PDIF cable.[26] A similar technology known as DTS Connect is available from competitor DTS. An important benefit of this technology is that it enables the use of digital multichannel sound with consumer sound cards, which are otherwise limited to digital PCM stereo or analog multichannel sound because S/PDIF over RCA, BNC, and TOSLINK can only support two-channel PCM, Dolby Digital multichannel audio, and DTS multichannel audio. HDMI was later introduced, and it can carry uncompressed multichannel PCM, lossless compressed multichannel audio, and lossy compressed digital audio. However, Dolby Digital Live is still useful with HDMI to allow transport of multichannel audio over HDMI to devices that are unable to handle uncompressed multichannel PCM.


These configurations optionally include the extra low-frequency effects (LFE) channel. The last two with stereo surrounds optionally use Dolby Digital EX matrix encoding to add an extra Rear Surround channel.


Many Dolby Digital decoders are equipped with downmixing to distribute encoded channels to speakers. This includes such functions as playing surround information through the front speakers if surround speakers are unavailable, and distributing the center channel to left and right if no center speaker is available. When outputting to separate equipment over a 2-channel connection, a Dolby Digital decoder can optionally encode the output using Dolby Surround to preserve surround information.


The system is used in bandwidth-limited applications other than DVD-Video, such as digital TV. The AC-3 standard allows a maximum coded bit rate of 640 kbit/s. 35 mm film prints use a fixed rate of 320 kbit/s, which is the same as the maximum bit rate for 2-channel MP3. DVD-Video discs are limited to 448 kbit/s, although many players can successfully play higher-rate bitstreams (which are non-compliant with the DVD specification). HD DVD limits AC-3 to 448 kbit/s. ATSC and digital cable standards limit AC-3 to 448 kbit/s. Blu-ray Disc, the PlayStation 3 and the Xbox game console can output an AC-3 signal at a full 640 kbit/s. Some Sony PlayStation 2 console games are able to output AC-3 standard audio as well, primarily during pre-rendered cutscenes.


Apple HDMI to HDMI CableThe Apple HDMI to HDMI Cable lets you connect an Apple TV, Mac mini, or other HDMI device to an HDTV or A/V receiver. Both high-definition digital video and multichannel digital audio are delivered over this single cable for stunning picture and sound.


The channels in a 5.1 audio mix serve distinct purposes. The three front channels (Left, Center, and Right) provide crisp, clean dialogue and accurate placement of onscreen sounds. The twin surround channels (Left Surround and Right Surround) create the sense of being in the middle of the action.


This article assumes that you have an understanding of the common terms related to digital audio like frequency, sampling rate, and channels. If not, do check my article on the basics of digital audio here.


5.1ch is short for 5.1 channels. This is a way to provide surround sound a theater-like experience. Five speakers plus a subwoofer are positioned around the listener, with each receiving a different channel as follows:


Note: The subwoofer, which receives the LFE channel can be placed anywhere in the room. Compared to a surround sound system without a subwoofer, this saves space because all the low frequencies are sent to the subwoofer. The other speakers can be smaller as they don't need to produce bass.


Unlike normal CD audio, SA-CD supports 5.1ch surround sound as well as 2-channel (stereo) sound. SA-CD audio is encrypted for copy protection purposes, which means it can be played through analogue, HDMI or i-Link output cables, but not through optical or coaxial cables.


In a 5.1ch or 7.1ch surround sound system, a subwoofer is a speaker that reproduces only low frequency sounds or the dedicated LFE channel. Because our hearing can't easily tell which direction low frequencies are coming from, a subwoofer can be placed anywhere in a room.


5.1ch and 7.1ch surround sound are systems for sending separate audio channels to speakers positioned all around the listener, giving a richer listening experience. The .1 refers to the use of a subwoofer as an additional low-frequency speaker.


Only if your audio format is dts/dolby digital 5.1, the 5.1 channel could activated in VLC. If the original file is of only stereo type, the 5.1 option will not get highlighted in the above said menu. You try using SURCODE DTS and Gold wave software for converting a stereo file into user defined 5.1 DTS file.


Dolby Digital is a multi-channel audio codec from Dolby Labs. It delivers a cinematic surround sound experience and is commonly referred to as the 'industry standard' (primarily because Dolby Labs has been around longer than DTS).


Both DTS and Dolby Digital are audio compression technologies, allowing moviemakers to record surround sound that can be reproduced in cinemas as well as homes. Both deliver spine-tingling multi-channel sound, so what's the difference? And which is better?


In their most basic form, both DTS and Dolby Digital support 5.1-channel audio (i.e. a typical home cinema system with five speakers and one subwoofer). And more advanced versions of the formats support 7.1-channels, HD surround sound and overhead speakers, in the form of DTS:X and Dolby Atmos.


The first film to use Dolby Digital was Batman Returns in 1992. Since then, Dolby has released a slew of increasingly advanced codecs, including Dolby Digital Plus, which supports HD surround sound and up to 7.1 speaker channels.


Like Dolby Digital, DTS has since released a plethora of more advanced surround sound formats including DTS-HD High Resolution, which supports up to 7.1 speaker channels. DTS has also brought out a lossless format, DTS-HD Master Audio. There is also DTS:X, which competes with Dolby's Atmos.


DTS stands for Digital Theater Systems and is a series of multichannel audio technologies specializing in digital surround sound formats widely used in film industry, music sharing, and Home Theater. Stephen Spielberg debuted the format in 1993 to improve the sound quality and his Jurassic Park was the first home video release to contain DTS sound. With a DTS player or DVD player hooked up to a surround home theater or receiver with built-in DTS decoder, you can play DTS files movie blockbusters on computer at home with theater effect to enjoy the high definition audio quality.
