Äänikortit

Äänikortti, or sound card, is a hardware component that allows a computer to process and output audio signals. It converts digital audio data into analog sound that can be reproduced by speakers or headphones, and conversely, converts analog audio from a microphone into digital data that the computer can process. Sound cards are essential for multimedia applications, gaming, music production, and general computer use.

Modern sound cards often integrate multiple channels for surround sound, offering a more immersive audio experience. They also typically include features like digital-to-analog converters (DACs) and analog-to-digital converters (ADCs) for high-fidelity audio playback and recording. Connectivity options usually include audio jacks for microphones and speakers, as well as digital outputs like S/PDIF for connecting to external audio equipment.

Sound cards can be internal components, installed directly into a computer's motherboard or expansion slots, or external devices that connect via USB or other interfaces. While most computers come with integrated sound capabilities on their motherboards, dedicated sound cards are often preferred by audiophiles and professionals seeking superior audio quality and advanced features. The development of sound card technology has significantly contributed to the evolution of computer audio and multimedia capabilities.
