This video explains how a digital-to-analog converter gives you better sound from the music stored on your computer.
You've got music stored on your computer, but do you know what happens when you try to listen to it? In order for those music files to play through headphones or speakers, they have to be converted from their digital forms into analog signals. When you plug your headphones or speakers directly into your computer's headphone jack that digital to analog conversion happens in the computer's sound card: a sound card that more often than not does a fair but not great job of conversion. Your music can be missing important details that can make it sound, well, dull and lifeless. That's where an external digital-to-analog converter, or DAC, can help. Through your computer's USB port it receives the original digital file and converts it using its own high performance DAC. You'll hear your music with all its original detail. Which means it will have much more presence. Which means much more musical enjoyment for the listener you.
