This article will give you a detailed explanation of what is a sound card in the computer. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

The sound card, also known as the audio card, is the most basic component of the computer multimedia system, and it is a kind of hardware to realize the mutual conversion of sound waves and digital signals. the basic function of the sound card is to convert the original sound signals from microphones, magnetic tapes and optical discs and output them to headphones, loudspeakers, amplifiers, tape recorders and other sound equipment.

Sound card (Sound Card), also known as audio card (called sound card by RTHK), is the most basic part of computer multimedia system, and it is a kind of hardware to realize the conversion between sound wave and digital signal. The basic function of the sound card is to convert the original sound signals from microphones, tapes and CDs and output them to sound devices such as headphones, loudspeakers, amplifiers, tape recorders, or to produce the sound of synthetic instruments through the music equipment digital interface (MIDI).

Composition

Digital signal processing chip

The digital signal processing chip can not only record and play all kinds of signals, but also complete many processing tasks, such as audio compression and decompression, changing sampling frequency, interpreting MIDI instructions or symbols, and controlling and coordinating direct memory access (DMA).

Amax D and Dmax A converters

Sound originally appears in the form of an analog waveform and must be converted into digital form before it can be used in a computer. In order to achieve this conversion, the sound card contains an Ahand D converter that converts analog signals into digital signals, so that the data can be stored on disk.

In order to send the sound output signal to the loudspeaker or other equipment, the sound card must use the DhampA converter to convert the digital sound in the computer into an analog signal.

Bus interface chip

The bus interface chip transfers commands and data between the sound card and the system bus.

Music synthesizer

The music synthesizer is responsible for synthesizing digital audio waveform data or MIDI messages into sound.

Sound mixer

The mixer can mix sound signals from different channels, such as microphone or line input and CD input. In addition, the mixer also provides users with the function of software to control the volume.
