What is Sound Card?
A sound card, also known as an audio card or audio interface, is a piece of hardware in a computer that allows it to play, record, and process sound.
The sound card typically has audio input and output ports, such as a headphone jack, microphone input, and line-in input. It may also have additional features such as MIDI input and output, digital audio input and output, and surround sound support. The sound card converts digital audio signals into analog audio signals that can be played through speakers or headphones. It can also convert analog audio signals into digital audio signals that can be processed and recorded by the computer. Sound cards can vary in quality and features, with higher-end cards offering better sound quality and more advanced features such as multiple input and output channels, higher sampling rates, and support for professional audio applications. While most modern computers come with a built-in sound card, some users may choose to upgrade to a higher-quality external sound card for improved sound quality or to support more advanced audio applications.
