How are audio cards classified?

Audio cards are classified according to the number of sampling quantization bits. The higher the number of bits, the higher the quantization accuracy and the better the sound quality; the audio card is also called a sound card. It is the most basic component of multimedia technology and is the implementation A hardware that converts sound waves/digital signals to and from each other.

Sound Card (Sound Card) is also called an audio card (called a sound effect card in Hong Kong and Taiwan). It is the most basic component of a computer multimedia system and is the key to realizing sound wave/digital A piece of hardware that converts signals to each other. The basic function of a sound card is to convert original sound signals from microphones, tapes, and compact discs, and output them to sound equipment such as headphones, speakers, amplifiers, and tape recorders, or to emit the sounds of synthetic instruments through the Music Equipment Digital Interface (MIDI).

Main functions

1. Digital sound files. Through the control of the sound card and the corresponding driver, the signals from the microphone, radio recorder and other sound sources are collected, compressed and stored in the computer system's memory or hard disk.

2. The digital sound files compressed by the laser disc are restored into high-quality sound signals, which are amplified and then released through the speakers.

3. Process digital sound files to achieve a specific audio effect.

4. Volume, combine various sound sources to realize the function of reverberation.

5. Synthesis technology, reading text information through sound card. Such as reading English words and sentences, playing music, etc.

6. Audio recognition function allows the operator to use passwords to command the computer to work.

7. Electronic musical instruments. In addition, with the help of the driver, the sound card can output files stored in MIDI format to the corresponding electronic musical instruments and produce corresponding sounds. Make electronic musical instruments commanded by the sound card.
