äänikortista

An äänikortti, or sound card, is a hardware component that allows a computer to send audio signals to an audio device such as a speaker or headphones. It also enables a computer to receive audio signals from a microphone. Sound cards are responsible for converting digital audio data from the computer into analog audio signals that can be heard, and vice versa.

Modern sound cards typically include features such as digital-to-analog converters (DACs) for outputting sound and analog-to-digital converters (ADCs) for inputting sound. They also often incorporate digital signal processors (DSPs) for various audio effects and enhancements. Many sound cards offer multiple audio input and output jacks, allowing for the connection of different devices like microphones, line-in sources, speakers, and headphones.

Sound cards can be integrated directly onto the motherboard of a computer, known as onboard audio, or they can be separate expansion cards that are installed into an available slot. Integrated sound solutions are common in most personal computers and laptops, providing basic audio functionality. For users who require higher fidelity audio, more advanced features, or specialized audio processing capabilities, dedicated sound cards offer superior performance and a wider range of options. These dedicated cards can be crucial for audio professionals, gamers, and audiophiles.
