What is the use of a good sound card, and what are the benefits of a sound 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. The basic function of the sound card is to convert the original sound signal from the microphone, tape, CD, and output it to earphones, speakers, amplifiers, tape recorders and other sound devices, or to make the instrument sound beautiful through the ** device digital interface (MIDI).

You tell me?

A sound card is an adapter for your computer to do sound processing. It has three basic functions: one is the synthesis pronunciation function; the second is the Mixer function and the Digital Sound Effects Processor (DSP) function; The third is the input and output function of analog sound signals, the sound information processed by the sound card is stored in the form of files in the computer, and the sound card should be supported by corresponding software, including drivers, mixing programs (mixer) and cd** programs.

An interface card used to process sound in a multi-computer computer. The sound card can turn the voice from the microphone, tape recorder, laser record player and other equipment, ** and other sounds into digital signals for computer processing, and save them in the form of files, and also restore the digital signal to the real sound output, the interface at the end of the sound card extends from the back of the case, and there is an interface for connecting microphones, speakers, joysticks and MIDI devices.

Sound card is the most basic component of multi-** technology, is a kind of hardware to realize the mutual conversion of sound waves and digital signals, the difference between sound cards is as follows:

1. Differences in use.

Ordinary sound card: Born for entertainment, such as karaoke, you can modify your voice to sound better, add some reverberation or effects.

Professional sound card: Designed for professional audio applications such as film and television recording, song production, etc., it can create the same sound as the human voice.

2. Functional differences.

Ordinary sound card: monitoring function, you can hear your own voice; Mixing function, singing while adding accompaniment sounds;

The reverberation function is added with the echo function when speaking;

The reverberation function, the voice is relatively close to the background**, and it sounds smooth;

Dodge function, the accompaniment sound will be lowered when speaking, and the accompaniment will be raised again after speaking;

Professional sound card: It has all the functions of the above ordinary sound card, but it focuses more on the sampling accuracy of the sound, that is, the grasp of the degree of delicacy.

3. The difference on **.

Ordinary sound card: If you use it for watching movies at home and have a slight requirement for sound quality, a sound card of 100-200 yuan can be satisfied;

You need karaoke, recording, that is, you need to mix, you need to consider a sound card of 300 and above.

Professional sound card: due to fine workmanship, exquisite materials, with extremely high performance indicators (low distortion, high signal-to-noise ratio, etc.), the manufacturing cost is much higher than that of K singing sound card, and some high-end professional cards are even more than 10,000.

Thrust, sound quality, low noise, and resolution are definitely different. It also depends on the use, enjoy** Professional recording, play games and watch movies The sound card you choose is different Choose what sound card you want to use Don't just look at it** Don't buy the wrong one If you buy the right one, don't buy the wrong one Although you get what you pay for, it's like a sports car and a main battle tank Definitely the tank is more expensive, but what is your purpose Is it for enjoyment or war This is the truth. The best thing you need is a sound card + preamp plus other equipment.

The difference is very big, it will produce the reverberation effect of singing in KTV, you can also set the automatic singing and the host shouting microphone effect, and there are many functions, shotgun change.

It is not impossible to achieve that effect, it is necessary to invest a lot of money to buy good equipment, the quality of the sound card is directly related to the effect of the sound, a professional sound card costs 300,000 yuan, do you say that the sound it handles is not good?

The integrated sound card is mainly focused on ordinary voice chat and recording such as recording and playback. In addition to the normal sound function, the independent sound card also has special effects recording and other functions, and supports professional recording operations.

2. The sound effect is different.

Although the integrated sound card has some built-in sound effects such as valleys, auditoriums, etc., these sound effects can only be heard by the user himself, and these sound effects cannot be heard in the recording and chat rooms. The discrete sound card also contains a number of sound effects, which can be synchronized with the output, so that recordings can be recorded and heard in chat rooms.

3. Audio processing efficiency.

The stand-alone sound card is slightly higher than the integrated sound card in terms of analog-to-digital conversion and analysis, and its output speed is also higher than that of the integrated sound card.

The sound card is divided into an integrated sound card and an independent sound card, both of which have the following functions:

1. Process the digitized sound file to achieve a specific audio effect;

2. Control the volume of the sound source, combine various sound sources, and show the alarm function of the reverberator;

3. Restore the digital sound file compressed by the hard disk or laser disk of the trapped bend shed into a high-quality sound signal, and release it through the speaker after amplification;

4. Digital sound files can be recorded. Through the control of the sound card and the corresponding driver, the signal from the microphone is collected, compressed and stored in the memory of the computer system;

5. Provide MIDI function, so that the computer can control multiple electronic musical instruments with MIDI interface.

Summary. Hello dear, glad to answer your questions The main functions of the sound card are digital audio processing, waveform sound acquisition and digitization, etc. The processed digital waveform sound is restored to an analog signal, and the sound is amplified by power and output.

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

The sound card is a kind of hardware that realizes the switching of digital signals and analog signals, and acts as a bridge to decode digital audio files such as *** and convert them into analog signals for the sound emitted by the speaker sound generating unit. The following is a detailed introduction: 1. The sound card is a kind of hardware that realizes the switching of digital signals and analog signals between each other, which is due to the fact that the audio files we usually use are digital files, which need to be converted into analog signals to make the speaker make sound, and the sound card is the medium of conversion; 2. There are two main forms of sound cards, the most common on-board sound card is the sound card integrated on the computer motherboard, even if there are some high-end motherboards that destroy the sound part and isolate it separately, but it is still regarded as an on-board sound card; There is also a discrete sound card similar to a discrete graphics card, which is connected to the motherboard through an interface such as PCI-E, providing independent sock audio output and more post-production audio options; 3. At present, there is an external sound card device that is mostly used by professionals and anchors for live broadcasting, which can provide independent microphone and monitoring interfaces, and has a knob with a variety of effect adjustments, which can realize functions such as reverberation and effect sound;
