In computer the audio signals are stored in the form of digital. ... then each 0 and 1 is stored into a memory as a raw data buffer corresponding to the recorded audio. it can be stored as file on disk and compressed as mp3 with a compression algorithm. with some audio command, you directly listen to the file.
How does optical audio work?
In an optical audio setup, the digital electrical signal from the source -- say, a DVD player -- is converted into light by a device called a transmission module. In Toslink, this module consists of an LED, or light-emitting diode, and a drive circuit, usually sent through plastic fiber, whereas ST Fiber Optic uses glass fiber and a red laser light at a 680-nanometer-wavelength [sources: Modern Home Theater; Toshiba ]. The signal then speeds along the optical cable to the destination device, usually a television or audio receiver, where a lightreception module converts it back into a digital electrical signal. From there, the device transmits it to your speakers or headphones.
What is fiber optic cable?
Fiber-optic cables offer the kind of low signal loss and high data rates that telephone and Internet users demand by transmitting information as light through thin plastic or glass wires. These cables have total internal reflectance, meaning that light bounces along inside them without escaping. Glass fibers can transmit such "lossless" signals over great distances without needing a power boost [sources: Encyclopaedia Britannica; Wood ].
What is HDMI audio?
Optical audio's chief competition and the current reigning champion of AV cables, HDMI (high-definition multimedia interface ) transmits an uncompressed 1080p video signal and up to eight channels of digital audio [source: Derene ]. Optical cable interfaces can handle digital audio 6.1 and 7.1 but their smaller data-transfer rate (20-125 megabits per second compared to HDMI's 10.2 gigabits per second) means they can only transmit compressed audio, such as Dolby Digital, DTS or two-channel PCM. HDMI, conversely, can deliver uncompressed Dolby TrueHD or DTS-HD MA signals [sources: Kim; Toshiba ].
What is composite cable?
Component and composite cables carry video signals but no audio. Composite cables, usually designated by a yellow RCA jack, pack all of the video info into one signal, whereas component ones split it into three channels across three plugs [source: Maxim Integrated Products ].
What was the first analog audio jack?
It's an apt comparison, considering that the first analog audio jack, the triple contact plug, or TRS connector , was adapted from the jack first used in telephone exchanges. The t ip, r ing and s leeve design, in which three insulated sections of the prong handled left channel, right channel and ground, respectively, was so successful that it is still widely used today [sources: International Textbook Company; Modern Home Theater].
Is optical cable better than HDMI?
Optical's main advantage over HD MI used to be price but as of 2012, low-end HDMI cable costs have come down to competitive levels (high-end cables are another story). Also, the kind of high-quality soundtracks that require HDMI aren't currently available in broadcast, cable or satellite TV, so for now the benefits of HDMI are limited primarily to Blu-ray [source: Spector ].
Do you need a separate cable for audio?
Both require a separate cable to handle audio, which brings us back to RCA jacks and other copper-wire solutions -- and an alternative, optical audio.
What is optical fiber?
An optical fiber is a very flexible transparent fiber made up of silica or plastic. Besides, it is around 1millimeter thickness.
Why Optical Audio is employed?
In addition, they won’t pick up environmental noise. Since they do not conduct electricity, the component devices are immune to electrical hazards. The digital audio signals are converted into light waves in this connection and send along the optical fiber cable. The cable is TOSLINK cable. And the port is called TOSLINK port.
What is Optical Audio or Optical?
Optical audio is commonly used in consumer audio equipment via digital optical sockets. It carries a digital audio stream from component equipment. That audio signals sent through them can be decoded to two channels of uncompressed lossless PCM ( pulse code modulated) audio or compressed 7.1 or 5.1 surround sound such as Dolby Digital or DTS surround system. The do not have the bandwidth to carry the lossless versions of Dolby TrueHD or DTS HD Master Audio. Even they are not capable of carrying PCM Audio signals of more than two channels.
How long is a Toslink cable?
The one mille-meter high-quality plastic fiber is used in the plastic optical cable. Depending on the required bandwidth and application, quartz glass optical fibers and multistrand plastic fibers can be used. The Toslink optical cables are usually 5 meters, and to the maximum, it may be around 10 meters. The further added length of cable should use a signal booster or repeater.
What is HDMI ARC?
HDMI ARC stands for High-Definition Multimedia Interface Audio Return Channel. It was introduced in the HDMI 1.4 Standard Specification in 2009. Now all almost all HDMI Cables adhere to this standard protocol. This protocol helps the Source device and Sink device establish two-way communications between them through the HDMI cable. Since this ARC protocol enables two-way communications between the connected devices via HDMI Port, this allows the audio signals to transfer to and from the devices. Therefore it eliminates the need to use audio cables.
Why does my optical connection not support SACD?

Why is fiber optic cable used?
Fiber optic cables were originally developed in the 1950s for endoscopes. The purpose was to help doctors view the inside of a human patient without major surgery.
How does light travel down a fiber optic cable?
Light travels down a fiber optic cable by bouncing off the walls of the cable repeatedly. Each light particle (photon) bounces down the pipe with continued internal mirror-like reflection.
How many types of fiber optic cables are there?
There are four types of multimode fiber optic cables, identified by “OM” (optical multimode). An industry association designated them as OM1, OM2, OM3 and OM4. They are described by ISO/IEC 11801. OM4’s standard was approved by TIA/EIA 492AAAD. Each OM has a minimum Modal Bandwidth requirement.
What is multimode fiber optic cable?
Multimode fiber optic cables are used as patch cords or “jumpers” to interconnect data equipment. Multimode fiber is the other type of fiber optic cable. It is about 10 times larger than a single mode cable. The light beams can travel though the core by following a variety of different paths, or in multiple different modes.
What is duplex fiber cable?
A duplex fiber cable consists of two strands of glass or plastic. Fiber Optic Cable on Crate Reel, with Pre-terminated ends. fiber. Typically found in a “zipcord” construction format, this cable is most often used for duplex communication between devices where a separate transmit and receive are required.
What is single mode fiber?
Single mode fiber is the simplest structure. It contains a very thin core, and all signals travel straight down the middle without bouncing off the edges. Single mode fiber optic cables are typically used for CATV, Internet, and telephone applications, where the signals are carried by single mode fibers wrapped into a bundle.
What is fiber optics?
Fiber optics, or optical fibers, are long, thin strands of carefully drawn glass about the diameter of a human hair. These strands are arranged in bundles called optical cables. We rely on them to transmit light signals over long distances.
How does optical cable work?
A digital optical cable transmits digital signals as on/off pulses of red light that go between the components. The light itself is a basic LED light, not a laser light. Optical cables are immune to the effects of Radio Frequency Interference (RFI) and Electromagnetic interference (EMI). However, to ensure good performance, the cable must have a bandwidth of 9MHz, and it is better to have 11MHz. The cables are limited to runs of no more than five meters, though in theory the cables can go to 10 meters. Longer runs need signal boosters to work.
What is the best size for digital optical cables?
Digital optical cables are best constructed of multiple, small diameter (less than 200 micrometers) fibers, rather than a single strand. The connectors themselves should be well polished, and the cable should be round.

Why does my TV have a ground loop?
One of the most common causes of a ground loop in home media gear is poorly grounded cable TV equipment. In this situation, your power outlets and the connected media equipment are on one ground (hopefully, if your house is up to code, the main earth-ground spike outside) but the coax cable is grounded to another ground (often a water-pipe ground if there is a water pipe or spigot near where the cable enters the home).
How many channels does a toslink cable have?
Advertisement. The TOSLINK system is still capable of carrying up to 7.1 channels of very high-resolution audio. For the majority of consumer setups, there will be absolutely no discernible difference between audio quality when using an HDMI cable or a TOSLINK cable.
Is toslink cable good?
Although the standard is over thirty years old now, it has been refined quite a bit, and modern TOSLINK connections are as useful as ever. So why is the lonely optical cable so underutilized? While that question could be a historical inquiry unto itself, here’s the short version: when TOSLINK came out, it was overpowered for most people’s needs, and by the time the average consumer was rocking an intense home theater, the TOSLINK cable had been eclipsed by the HDMI cable. (HDMI is not only simpler, since it carries video and audio together, but it also supports newer high resolution audio formats like Dolby TrueHD and DTS HD Master Audio. TOSLINK does not.)
Can Blu Ray players pipe audio?
If the Blu-ray player has a TOSLINK port, you can pipe out the audio through the optical port to your speakers or receiver. Here’s another example: you have a nice set of speakers hooked up to a quality receiver, but that receiver is old enough that it has no digital connections to speak of–including no TOSLINK port.
Can you use a toslink receiver on a TV?
You don’t have to take your premium paid-$1000-for-it-back-in-the-day receiver and put it on Craigslist for pennies on the dollar. The vast majority of HDTV sets as well as many Blu-ray players, game consoles, and other devices still have TOSLINK out ports. You can pipe the HDMI video from the source (say your cable box) into your TV, then turn right back around and pipe the optical audio out to your receiver and speaker system. Remember, TOSLINK has been on the market since 1983: there is good chance that a premium audio/video receiver manufactured anytime in the last decade or two has a TOSLINK port.
Can you use analog headphones with a TV?
What if you want to use a pair of analog headphones with your TV, but your spouse wants to use the speakers so they can listen at a different volume? Many television sets and receivers have a plain old headphone jack, but most of them kill the audio to the speakers when a headphone cable is plugged in. In this situation, you can use that same TOSLINK converter to send that audio to whatever you want, without the hassle of HDMI content protection standards.
