What is Sound Card?

What is a Sound Card?

A sound Card is an interior expansion that is utilized to input and output audio from a machine under the authority of a computer program. It is also used in external audio interfaces for professional audio apps.

What is a Sound Card

Sound Card is utilized with the help of a software app and the device driver. However, a computer doesn't need and sound Card because it is already included on every machine as an expansion slot, or it could be a built-in motherboard. Therefore, as an input machine, a microphone is kept to collect audio data. On the other hand, as output devices, headphones are used. Most of the headphones use 3.5 micrometers of minijacks.

When you convert the digital audio data into the analog audio, then it is a primary function of a sound Card by which speakers can play the sound. Just like that, in the back case of the microphone, the analog data is transformed into programmed audio data through a sound Card. All data is kept in computer devices as well as it can be modified with the help of audio software.

However, in some cases, the computer can contain an actual Card that will be in the PCI slot. But in this case, the sound card is also part of this in the motherboard. If you want to enhance the audio potential, then you can download a new sound card to your device. The Executive sound Card can support advanced sampling rates like 192 kilo Hz instead of 44.1 kilo Hz.

So, to enhance your vocal ability, you can also install an execution sound Card. If you want to use multiple channel recordings, you can use the breakout box. Basically, it comprises numerous audio connections and a built-in sound card, so it can be called an external box. Just assume that you are using ten channels for some purpose. Then you cannot use a single Card. You can use the breakout box. In the breakout, some breakout boxes can connect with the box. Almost the entire burst connects to a FireWire or USB port.

Description of sound card

Sound Card is Hardware in the shape of a rectangle that has different types of ports to connect different audio devices like speakers, headphones, and some others. We know that motherboard, peripheral device, and other devices are designed with compatibility in mind, so when you install them, it fits outside the back of the case. This makes us too easy to use. You also have the opportunity with the sound card to plug in the speakers, headphones, and others. Because it also uses a USB sound card. You can also plug it directly into the USB port with the small adapter.

Some years before, when it was not developed, then there was using a narrow range of frequencies, computers that produced the beeps only, which is used in warning alarms.

Then after that time, for the executive use or the fun use, the requirement for giant standard sound increased by growing in multimedia. To full fill this wish, there is created Adlib sound Card. In this sound Card, there are nine voice mode features present that make programmable audio possible.

Now for the computer, most motherboard creators create built-in sound cards. But for particular requirements, an advanced user uses expansion cards.

Types of sound Card

Sound is an expansion component of the computer, which helps us to hear audio from video files, MP3 files, and many others. In the year of 1990s, sound card is firstly put in the mainstream. In the latest computer, there is already one available.

Basically, the sound card is divided into three parts, and all have their own advantages. They are as follows:

1. Motherboard sound chips:

For the first time, the sound card is very expensive. It cost 100 dollars. When the computer sounds technology is present at a low price, then miniaturization technology allows computer hardware technology to provide sounds in a single chip. In the latest computer, you can find the sound chip in every system, even if the computer already contains a separate sound card. The sound chip of the motherboard made it easy for all computer users. You can find the sound chip in the motherboard of your system.

2. Standard sound Card

In the computer standard sound card is attached to be included in the slots. If you are utilizing the standard sound card other than the motherboard's sound chip, then in the standard sound card, there are its own processor chips, but in the motherboard sound chip, it releases sound on the footing of the computer processor.

What is a Sound Card

In the standard sound card, if you are playing the game, then it is the best opportunity because it provides better performance. And it creates less load on the main processor and the game will work smoothly so, in this way standard sound card is far better as compared to the Motherboard's sound chip.

3. External sound card

External sound cards have all functionality that has a standard sound card. It uses USB or FireWire port to connect it to the computer instead of using an internal expansion slot. It also has some other functions that standard sound card has not like: To control physical volume control knobs or advance input-output. When you compare it with a standard sound card, which has no feature of moving a sound adapter from one device to another but in this, it is easy to move the external sound card from one to another.

Uses of Sound Card

There are many uses of sound card, but the main use of it is to help us to listen to the playing music with the various formats and degrees of control. The source of sound may be in countless forms like CD, DVD, file, or it may be streamed audio. In the world their many apps for a computer where a sound card can be utilized, which are the following:

  • Watching Movies
  • Recognition of sounds
  • Sounds of games
  • Listening to music
  • In the Educational software
  • In the presentation on business

History of Sound Card

The initial sound card is used through PLATO terminals that are considered to be the Google Synthetic Woodwind. It had synthesizer potential of 4 voice music synthesis. It was developed by Sherwin terminals in 1972.

And then Apple II was the first computer, which is capable of using a plug-in sound card. Also, the Apple Music Synthesizer was the initial plug-in sound card, which is utilized by Apple II. It was developed by AFL Product Inc. in 1978.

And Adlib was the first company that developed a sound card for IBM PC. The company created the sound card in 1987 based on the Yamaha3812 sound chip.

Until 1988, a sound card was not very uncommon in IBM PC for most IBM PC customers to provide sound and music, and for that, the interior PC speaker was the just method. Then when the music is playing, there is a need to stop all other processing.

Sound Card Connection or color codes

In there is a sound Card, there are many Components. But the main components are the following:

  1. Digital signal processors (DSP), which are also called specialized processors, work on all digital audio processing.
  2. Digital Analog Converter (DAC) is used to convert the computer's voice data into the related signal data for being sent to a sound machine.
  3. Analog-Digital Converter (ADC) is used to transform the related input signal into automated data, which a computer can do.

External input/output connectors

  • One or two standard 3.5mm line-out jacks, which are usually in light green color.
  • A line-in jack.
  • SPDIF digital output device, which sends digital voice information to an automated amplifier by utilizing the coaxial cable with the help of RCA connectors at the ends.
  • MIDI connector. It is basically in gold color, which is used to connect musical instruments.

Internal input/output device

  1. CD-ROM / DVD-ROM is a black socket that is used to attach the sound card to the CD-ROM-related audio output utilizing a CD voice cable.
  2. Auxiliary input is a white socket that is used to connect internal audio sources like a TV tuner card.
  3. The telephone answering device connector (TAD) is available in green color.

Color Codes

In the sound card connector, there are many connectors that differentiate with the help of color, so there are some following color codes of the connector:


  • 701C
  • mm minijack
  • It is of Microphone symbol
  • Related microphone voice input


  • Minijack of 3.5mm
  • Related line-level voice output for nearby speakers.
  • Brown/ Dark
  • 4645C

Gold / Grey

  • 15 pin D
  • Game port / MIDI

It is in the sign of arrow going out twain edges into signals. This is not all the color codes, but yes, it is some important color codes that you can use in the future, or maybe you use currently.

Sound Card and Audio Quality

In the many computers, there is no sound expansion card. There is already available some technology integrated which is directly on the motherboard. These cards are called onboard sound cards. This expansion makes the computer less powerful and less expensive. For the professional, there is a serious need for a dedicated sound card. To divide a regular ground wire, because almost all of the desktop computers are initiated for the anterior facing headphone jacks and ports. So, if you have a USB, then you can plug it in, and you can listen to static in your headset.

What do if computer has no sound?

Now you know that if you disconnect the ports and power, there will be no communication between the sound card and the speakers. If you are not able to listen from the speakers, then it can be an issue in the software that can prevent the sound from playing. So firstly, make sure that your video and audio have proper sound.

There is also another reason, which audio you want to listen to can be corrupt or missing from the device driver. To solve this problem, you have to use any free driver updater tool, or you can install a sound card driver to solve this problem.

If you checked the above reasons and also your audio is not listenable, you have to install proper software for media playback.

How to choose a perfect sound card

You can find many sounds card that is available, but there is still some popular sound Card like Creative Labs, Diamond Multimedia, Turtle beach, etc.

Comparing sound cards

There is much functionality to compare one another the sound card but there is four main characteristics of sound card that are following:

Audio channel: Audio channel is related to the number of speakers and has also related to multi-directional or Omni directional headphones. As you add a greater number of channels, then there will be more directional. And the sound will be correct and clean.

Bit Depth: The range of bit depth varies from 8 to 24. You will see it spec toted around a lot. Many of us don't know about it. So first of all, the bit-depth manages the range of what you listen to, with 24-bit depth in the audio being nigh superbly correct. In the range, 16 is the minimum bare, and 24 is the highest end.

SNR: The full form of SNR is Sound-to-noise-ratio. When you plug in the speaker and turn it to high volume while this time you are not playing anything, then you hear buzzing that is called SNR. When the SNR is higher than there will be quieter background noise.

Sample Rate: The sample rate is dignified in KHz, and its range varies from 44.1 to 192 giant. There are some thoughts that audiophiles promise that the astronomically higher number is superior until you have world-class hearing and equipment. You have to listen to the contrast in almost all cases.

Advantages of sound Card

  • There are the following benefits of using the sound card:
    In the sound Card, it can assist more media channels, and 5.1 and 7.1 channel audio provide more ports for a superior surround sound speaker system and directional audio in headphones.
  • In the sound Card, it added better audio ports to the system. Which is in other systems don't have.
  • In the oldest system, the sound Card takes off the load of the CPU by handling the sound processing. But in the latest system, these differences are not noticeable.
  • In the sound card, there is an actually available shield to safe electrical involvement from the other constituent, but if there are unshielded sound cards, it creates a world of difference when it is plugged into the PCI slot on a motherboard apart from the entirely else.
  • The sound card provides the correct bass, sounds, and directional audio. If you are working with a low-end onboard sound chip, the leap to a sound card will be huge based simply on how abundantly clear you will be here. Remember that all the benefits of the sound card will be in the hardware that's good enough.

Disadvantage of the sound Card

  • The main disadvantage of a sound card is the price. That its introductory price is thirty dollars and it may be in several thousand dollars as per our required or high-end models.
  • It may also take a costly expansion slot in the motherboard, which could be used in other devices.
  • In different manufacturers may have additional support for the different programs and devices.
  • A particular card may not openly support alternative operating systems like: Linux, BSD bases, etc.
