6 What is the main function of a sound card?

Without a sound card, can your computer make sound?

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.

The connector at the rear of the sound card protrudes from the rear of the case, and there are connectors for connecting microphones, speakers, joysticks, and MIDI devices.

With the help of the driver, the sound card can output files stored in MIDI format to the corresponding electronic musical instrument and produce the corresponding sound. Make electronic musical instruments under the command of sound cards.

Sound card (sound

card): The 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. 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 earphones, speakers, amplifiers, tape recorders and other sound equipment, or through the ** equipment digital interface (MIDI) to make the instrument emit a wonderful sound The sound card obtains the sound analog signal from the microphone, and converts the sound wave amplitude signal into a string of digital signals through an analog-to-digital converter (ADC) and stores it in the 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). The main functions of the sound card are as follows: (1) It can record digital sound files.

Through the control of the sound card and the corresponding driver, the signal from the microphone, cassette recorder and other audio sources is collected, and the signal is stored in the memory or hard disk of the computer system after compression; (2) Restore the digital sound file compressed by the hard disk or laser disk into a high-quality sound signal, amplify it and release it through the speaker; (3) processing the digitized sound file to achieve a specific audio effect; (4) Control the volume of the sound source, combine various sound sources, and realize the function of the reverberator; (5) Using language synthesis technology to read text information aloud through sound cards. Such as reading English words and sentences, playing **, etc.; (6) It has a preliminary audio recognition function, allowing the operator to command the computer to work with a password; (7) Provide MIDI function, so that the computer can control multiple electronic musical instruments with MIDI interface. In addition, with the help of the driver, the sound card can output files stored in MIDI format to the corresponding electronic musical instrument and produce the corresponding sound.

Make an electronic musical instrument subject to the finger of the sound card.

A sound card is actually just a sound decoder that uses a specialized sound coder. and does not require CPU resources to consume decoding. Now the sound card is generally integrated.

The most used ones are AC97. Ordinary sound cards are very cheap. But there are also good sound cards, we can't afford to use them, and we don't need them.

The working principle of the sound card is actually very simple, we know that the microphone and the speaker are used analog signals, and the computer can process digital signals, the two cannot be mixed, the role of the sound card is to realize the conversion of the two. In terms of structure, the sound card can be divided into two parts: analog-to-digital conversion circuit and digital-to-analog conversion circuit, and the analog-to-digital conversion circuit is responsible for converting the analog sound signal collected by sound input devices such as microphones into digital signals that can be processed by computers; The digital-to-analog conversion circuit is responsible for converting the digital sound signal used by the computer into an analog signal that can be used by the speaker and other equipment, and it's as simple as that.

The role of the sound card is to increase the reverberation.

Noise reduction, beautification, vocal processing, etc.

The sound card is responsible for the sound processing of the computer's audio management.

A DAC converter card that converts digital signals to analog audio signal outputs.

No sound card and no sound, just like no monitor can't see.

To put it simply, it is a function of sound processing.

Without a sound card, the computer cannot make sound.

Function 2: Recording.

This is also one of the most basic functions of the sound card, which is to capture the signal from the microphone. With her, you can karaoke on the computer, entertain yourself, and have fun.

Function 3: Voice communication.

Function 4: Real-time effects.

A sound card is an input and output device of a computer, and its job is to provide input and output functions of audio signals and can process them. Sound cards include integrated sound cards and independent sound cards, and now integrated sound cards account for the vast majority of the market, and almost all motherboards now have sound cards that meet the AC97 standard. A discrete sound card is a type of board.

The basic functions of an integrated sound card are the same as those of a standalone sound card. Today's integrated sound card is very mature, and it is easy to cope with general use and has more and more functions. Today's independent sound cards are basically developed in the high-end of the network, so the general sound quality is better than the integrated, and the price is relatively high.

Let the computer make a sound, not be dumb.

Sound card, also called audio, is the most basic component of multi-technology and 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 a sound device such as headphones, or to make the instrument sound beautiful through the ** device digital interface (MIDI);

The sound card obtains the sound analog signal from the microphone, and through the analog-to-digital converter (ADC), the sound wave amplitude signal is sampled and converted into a string of digital signals, which is stored in the computer.

The sound card is an adapter for computer sound processing, which supports the function of synthesized pronunciation;

The sound card supports the Mixer function and the Digital Sound Effects Processor (DSP) function, and the input and output functions of the analog sound signal.

Responsible for converting computer voice commands into sound frequencies, mainly responsible for sound processing and output.

recording and playback of digital sound files; Control the volume of the sound source, mix it and then digitize it; compression and decompression when recording and playing back digital sound files; Textual Conversion and Speech Recognition.

Converts the sound signal of the computer into a form that can be received by the audio device and outputs it.

The main function is to convert the recorded and transmitted sounds, and convert the recorded sounds, such as QQ or YY, into the voice signals required by the computer, and then convert them into frequencies and frequencies that can be heard by the human ear through the sound card. You can hear what others are saying, and it's a process of mutual transformation.

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.

Take the live sound card as an example, because it needs to render the atmosphere in the process of live broadcasting, it needs the sound card to have this kind of function, and this kind of sound card is still relatively ordinary, the manufacturer has produced a lot of sound cards according to the different needs of the anchor, some powerful special effects sound cards, will independently combine the anchor's voice, and assist some special effects.

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.

I hope it can help you, remember to give it a thumbs up.

The function of the sound card is to beautify the sound and improve the sound quality. It is recommended to use Senran sound card It is easy to use and has complete functions.

The main function of the sound card is to optimize our sound, which is mainly to make the sound relatively stereo reverberant, and to ensure the good output of the sound effect, and the good reception of the radio effect.

The main function of the sound card is to let people who are not good at singing use the sound card to make it sing particularly beautiful and beautiful, which is to play an auxiliary role.
