AI overview
A sound card is an expansion card that lets your computer receive audio signals as input and send them back out as output, enabling you to listen to music, watch videos with sound, and use audio applications. It matters because without one, your computer would have no way to process and play the audio that's essential for entertainment, communication, and many other everyday computing tasks.

音效卡是多媒體電腦中用來處理聲音的接口卡。音效卡可以把來自話筒、收音機、錄音機、雷射唱機（鐳射影碟）等設備的語音、音樂等聲音變成數位訊號交給電腦處理，並以文件形式保存，還可以把數位訊號還原成為真實的聲音輸出。音效卡尾部的接口從機箱後側伸出，上面有連接麥克風、音箱、遊戲杆和MIDI設備的接口。 但自從各大主機板廠商推廣All-In-One的主機板以來，主機板皆內建AC97或HD Audio聲卡，迫使中低階的音效卡市場快速萎縮，僅剩高階、音響級與專業用途音效卡仍存在於市場。
