A sound card, also known as an audio card or audio adapter, is a hardware device used to process audio signals in a computer multimedia system. It is a bridge connecting the computer and audio equipment, enabling the computer to process and play sound. 1. Functions of a sound card The main function of a sound card is to process and transmit audio signals, including sound input and output. It can receive audio signals from devices such as microphones and line inputs, digitize them for storage in the computer, and output audio signals from the computer to devices such as headphones and speakers. 2. Types of sound cards Sound cards can be divided into PCI sound cards and USB sound cards based on interface type. PCI sound cards are directly plugged into the motherboard, while USB sound cards are connected to the computer through a USB interface. Additionally, sound cards can be classified as integrated sound cards and standalone sound cards based on their functions. Integrated sound cards are usually integrated into the motherboard, while standalone sound cards are independent hardware devices. 3. Parameters of sound cards The parameters of a sound card mainly include sampling rate, channel count, audio codec, etc. The sampling rate represents the number of times the sound signal is sampled per second. The higher the sampling rate, the better the sound quality. The channel count indicates the number of sound channels, commonly known as monaural and stereo. The audio codec determines the encoding and decoding capabilities of the sound card for audio signals.
