A digital-to-analog converter (DAC) is crucial for converting digital signals into sound in computing. This device transforms binary data from audio files into corresponding voltage levels that can drive speakers or headphones. The DAC processes the digital audio stream, interpreting the ones and zeros into an analog signal that replicates the original sound. This conversion is essential for playback of music, voice, or any audio content on electronic devices. Therefore, a high-quality DAC significantly influences the overall sound quality, affecting user experience positively.
