What is the function of the sound card. What role does the grade play

The basic function of the sound card is to convert the original sound signal from the microphone, tape, and CD, and output it to the sound equipment such as headphones, speakers, amplifiers, and tape recorders, or to make the instrument sound through the ** device digital interface (MIDI).

In fact, as an ordinary computer user,We may not often pay attention to the sound card,The reason is very simple,We don't have such high requirements for sound quality,It's better to buy a good set of speakers with that money。 However, for those who pursue better sound quality and ** producers, a good sound card is still essential.

Sound card (sound card) is also called audio card (Hong Kong and Taiwan call it sound effect card): sound card is the most basic component of multi-technology and is a kind of hardware that realizes the mutual conversion of sound wave digital signals.

It is still necessary to replace a better sound card,A good sound card can make the sound more textured,You can use various effects,You can improve the sound quality of playback,And so on,These are all incomparable to integrated sound cards,Recommend the innovative 0060,The price is within 200,The effect is great。

The sound card is also called the audio card (Hong Kong and Taiwan call it the sound effect card), is the most basic component of the computer system, is a kind of hardware that realizes the mutual conversion of sound wave digital signals.

The basic function of the sound card is to convert the original sound signal from the microphone, tape, and CD, and output it to the sound equipment such as headphones, speakers, amplifiers, and tape recorders, or to send out the sound of a synthesized instrument through the ** device digital interface (MIDI).

The sound card obtains the sound analog signal from the microphone, and through an analog-to-digital converter (ADC), the sound wave amplitude signal is sampled and converted into a string of digital signals, which is stored in a computer. During playback, these digital signals are sent to a digital-to-analog converter (DAC), which is reduced to an analog waveform at the same sampling speed, amplified and sent to the speaker to emit sound, a technique known as Pulse Code Modulation (PCM).

Summary. Hello! Introduction to the main role of the sound card, first, add special effects to the soundSome professional-level sound cards will launch some special effects, and this kind of sound card in addition to the basic functions of most sound cards, can also assist users to add some special effects to the sound, such as laughter, crying, shouting, applause, cheers, etc.

Take the live sound card as an example, because you need to.

Hello! Introduction to the main role of the sound card, first, add special effects to the soundSome professional-level sound cards will launch some special effects, and this kind of sound card in addition to the basic functions of most sound cards, can also assist users to add some special effects to the sound, such as laughter, crying, shouting, applause, cheers, etc. Take the live sound card as an example, because you need to.

Because it is necessary to render the atmosphere in the process of live broadcasting, it is necessary to have such functions on the sound card, and this kind of sound card is still relatively ordinary, the manufacturer has produced many sound cards according to the different needs of the anchor, and some powerful special effects sound cards will be independently combined with the anchor's voice to assist some special effects.

2. Make the sound better Those who have been to concerts and opera houses and listened to singers and actors sing must know that singing in that kind of special performance place, because of the special design of the building, there will be a different feeling, and this feeling cannot be experienced at home, which is why so many people like to listen to ** meeting. But if we install a sound card with this kind of function at home, then our own **songs,** sound can also become as pleasant as in concerts and opera houses, and even change our own timbre, such as electronic music, dolphin sound, etc., some professional-grade sound cards can do it.

3. Repair sound defectsIn fact, the biggest role of the sound card is to repair the user's voice defects, in addition to adding special effects to the sound, so that the voice of ** out is better, it can also make the sound of the user more perfect, if we are "fireworks voice, duck voice", unless it is a song suitable for yourself, otherwise it will be very difficult to sing out. But if you use this kind of special sound card, then the missing part of your voice can be made up by the sound card, and in some large singing evenings, there is a group of assistant singers who are responsible for the chorus, and they do this job.

And these are the functions of special sound cards, if it is just an ordinary sound card, it is nothing more than two functions, one is to assist the user to do sound input, and the other is to assist the user to do sound output. The former is the so-called microphone and recording function, and the latter is the projection and sound playback function of the equipment.

Hello! The above is an introduction to the main role of the sound card.

Realize the conversion of sound wave digital signals to each other.

The main function of the sound card is to convert the original sound signal such as microphones, tapes, and discs, and output them to sound devices such as headphones, speakers, amplifiers, and tape recorders, or to make musical instruments produce beautiful sound through MIDI.

The sound card can take the sound analog signal from the microphone, and the sound amplitude signal is sampled and converted into a series of digital signals through a hardware analog-to-digital converter (ADC) for storage in the computer.

Summary. A sound card is an interface card used to process sound in a multi-computer computer.

What is the role of the sound card.

A sound card is an interface card used to process sound in a multi-computer computer.

The sound card can turn the voice and sound from microphones, radios, tape recorders, laser record players (laser discs) and other devices into digital signals for computer processing, and save them in the form of files, and can also restore the digital signal to the real sound output.
