What is a computer sound card?
The computer sound card, also called the audio card (known as the sound card in Hong Kong and Taiwan), is the most basic component of multimedia technology and is a kind of hardware that realizes the mutual conversion of sonic /digital signals. The basic function of the sound card is to convert the original sound signal from the microphone, tape, and optical disc to the sound device such as headphones, speakers, amplifiers, recorders, etc., or to make the instrument sound beautiful through the music device digital interface (MIDI).
A computer sound card is an adapter for sound processing on a computer. It has three basic functions, one is the music synthesis pronunciation function; the second is the mixer ( mixer) function and the digital sound effect processor (DSP) function; the third is the analog sound signal input and output functions. The sound information processed by the sound card is stored as a file in the computer. Sound card work should have corresponding software support, including drivers, mixers, and CD players.
What are the classifications of computer sound cards?
1. Board-type computer sound card: Card-type products are the backbone of the market today. The products cover low, medium and high grades, and the price ranges from tens of yuan to thousands of yuan. Most of the early board-type products were ISA interfaces. Due to the low bandwidth, single function and excessive system resources, this interface has been eliminated. PCI has replaced ISA interface as the mainstream, and they have better performance. And compatibility, support plug and play, easy to install and use.
2. Integrated computer sound card: The sound card only affects the sound quality of the computer, and has nothing to do with the system performance that is more sensitive to PC users. Therefore, most users' requirements for sound cards are satisfactory, and they are more willing to invest in the part that can enhance the performance of the system. Although the compatibility, ease of use and performance of the board-type products can meet the market demand, in order to pursue cheaper and simpler, integrated sound cards have emerged. Such products are integrated on the motherboard, have the advantages of not occupying the PCI interface, lower cost, better compatibility, etc., and can meet the majority of audio needs of ordinary users, and are naturally favored by the market. Moreover, the technology of integrated sound card is also constantly improving. The advantages of multi-channel and low CPU occupancy of PCI sound card have also appeared on the integrated sound card, which has occupied a dominant position and occupied more than half of the sound card market.
3, external computer sound card: is an innovative thing launched by the innovative company, it is connected to the PC through the USB interface, has the advantages of easy to use, easy to move. But these products are mainly used in special environments, such as connecting notebooks to achieve better sound quality. There are not many external sound cards on the market, and there are two innovative types of Extigy and Digital Music, as well as MAYA EX and MAYA 5.1 USB.
