There are generally three main types of PC sound cards: integrated sound cards, which are built into the motherboard; external USB sound cards, which connect via USB ports; and high-end dedicated sound cards, designed for audiophiles and professionals that offer advanced features and superior audio quality. Each type serves different needs, from basic audio playback to professional audio production.

A sound card is a low-cost audio interface. All sound cards provide digital-to-analog conversion of audio waveform data. Most have analog-to-digital conversion from microphone and/or line-level inputs, as well. Some sound cards also produce waveforms from MIDI data, although that feature is rarely used, today.
