äänikorteissa

Äänikorteissa, which translates to "in sound cards" or "sound cards" in English, refers to the hardware component within a computer responsible for processing and outputting audio. Also known as a sound card, audio card, or sound adapter, this device converts digital audio signals into analog signals that can be reproduced by speakers or headphones, and vice versa for input devices like microphones.

Modern computers typically have sound capabilities integrated directly onto the motherboard, a configuration known as onboard audio. Dedicated sound cards, which are separate expansion cards that can be plugged into a PCI or PCIe slot, are still available and are often favored by audiophiles, musicians, and gamers who require higher fidelity audio, more advanced features, or specialized connectivity options. These dedicated cards often offer superior digital-to-analog converters (DACs) and analog-to-digital converters (ADCs), as well as a wider range of audio inputs and outputs.

The primary functions of a sound card include playing back music, sound effects, and voiceovers from software, recording audio from external sources, and supporting various audio technologies like surround sound. The specific capabilities and quality of audio playback and recording can vary significantly between different sound cards, from basic onboard solutions to high-end professional audio interfaces.
