Types of Sound Cards

Now these days, there are different kinds of sound cards that easily available in the market with less price. Few sound cards are built-in on your computer’s motherboard, but some you have to need attach via USB or FireWire ports. Therefore, you can prefer them as you’re convince; below mentioned five types of sound card, check them:

Motherboard Sound Cards

Motherboard sound cards are presented mostly each types of computer system in modern era; this card is built in along with PC’s motherboard, so you can say it as sound chip as well because you don’t need to install any external sound cards with your Computer.

These sound cards were most costly when firstly introduced in the market place. Computer sound technology became available with lesser cost, miniaturization technology got let computer hardware manufactures to provide sound into one chip. So, now these days, almost all motherboard sound chips are affordable for all computer owners.

Standard Sound Cards

Standard sound card is connected internally your computer with one of slots. It lets you provide great performance compare to motherboard sound chips, because it made with its own processor chips. So you can say that this sound card perform on the base of using of computer’ processor. While, you playing games, standard sound card offers better result as it makes less a load of main PC’s processor. 

External Sound Adapters

External sound adapters have almost all features similar standard sound card. Its shape likes as small box that enables all connection with using of USB or FireWire port, beyond of, using as internal expansion slot. They also are having other additional features that are not available into standard sound card, like as physical volume control knobs and extra input and out controlling system. You can easily swap an external sound adapter to new PC as standard sound card. You can also upgrade the sound of your laptop or PC by using USB or FireWire expansion slots.

Internal Gaming Cards

Gaming sound cards have own separate processors, which provide better audio, erasing the work of making it from your PC’s CPU. They also contain own set of inputs/outputs that mostly have good shielding and, like as lesser noise levels compare to inputs/outputs embedded into your computer system. Mostly gaming sound card are designed with advance technology that let assist to locate created sound in 3D space and it is easier to hear.

Audiophile and Recording Cards

These sound cards offer ultimate sound quality, and these special cards are used either the audiophile market or the professional audio market. Audiophile sound cards contain massive shielded outputs/analogue circuitry that objectives to both decrease the noise levels, then accurately regenerate sound signals. 

Uses of Sound Card

The main aim of using sound card is to offer audio that lets you to hear with playing song and watching movie along with several formats and degrees control system. There are various sectors where this sound card can be used; below shown few areas:

Real life Applications of Sound Card are:

  • Playing game and watching movies
  • Audio and video conferencing
  • To make attractive business presentations
  • Listening music & Audio CDs
  • To create and play MIDI
  • Using into Voice recognition
  • Using educational software that means while watching educational tutorial, you can hear sound to improve the experience in education.
  • Using to record dictations

Functions of Sound Card

Sound card is an expansion hardware part that is used into PC to grab and send audio. Software applications and device drivers let you help to get configuration in this sound card.

Computer input devices are connected to receive audio data like as microphone, and output device are linked to spread the audio data usually headphones or speakers.

Sound card lets to convert incoming digital audio data into analog so that headphones can play it. In the opposite scenario, this card can also convert analog audio data from the microphone to digital data that can be kept to save on the computer by using audio software.

How Does Sound Card Work?

When you will try to listen to voice of sound card then sound in the form of digital data waveform.wav or mp3 sent to sound card. DSP (Digital Signal processing) lets to process the digital data by using of DAC (Digital Analog Converter). Once converted digital signal into an analog signal that is amplified, and analog signal is spread via speaker.

If you get ready to record sound with using of a microphone, then this sound is processed into analog format by using DSP, the mode ADC (Analog Digital Converter: Convert analog to digital). Then it converts the analog signal into digital signal that is stored into table format or regular waveform written .wav (wave) in a disk or compressed into other forms such as mp3.

Sound Card Connections

The image is an example of a sound card audio ports or audio jacks on the rear side of your PC with attached color and connectors symbols. Here shown you 5 audio jack are used with devices that is used the 3.5 mm mini plug.
