äänikortissa

Äänikortti, often referred to as a sound card in English, is a hardware component that enables a computer to process and output audio signals. It's responsible for converting digital audio data into analog signals that can be heard through speakers or headphones, and conversely, for converting analog audio from input devices like microphones into digital data that the computer can process.

The primary functions of an äänikortti include audio playback and recording. Modern äänikortit are typically integrated directly onto the motherboard of a computer, though dedicated expansion cards offering higher quality audio or additional features are also available. These devices contain a digital-to-analog converter (DAC) for outputting sound and an analog-to-digital converter (ADC) for inputting sound.

Key components of an äänikortti include the audio codec, which handles the conversion processes, and various connectors for microphones, line-in, line-out, and headphone jacks. The quality of an äänikortti can significantly impact the listening and recording experience, affecting factors such as sound fidelity, clarity, and the presence of noise. Drivers are essential software components that allow the operating system to communicate with and control the äänikortti's functionalities.
