Most of us listen to music digitally in today’s world, but many of us do not understand exactly how this works. You see, sound waves are not digital in their very nature, but analog. This is why there are still quite a few people today who appreciate listening to vinyl records instead of digital media, as the vinyl record will give you an analog sound that is closest to the original sound of the music, and so there is a warmth on a vinyl record that is typically not present in digital forms of music. However, collecting records takes up a whole lot of space, and so it is much more convenient for us music lovers to store all of our music in digital form so that we can access it rather easily. In order for digital music to be turned into sound, however, a digital to analog converter, or DAC, is needed. There is excellent information about how this works at microchip.com.
Basically, the digital signal of 1s and 0s that is found in the audio file has to be translated to an analog signal in order for us to be able to listen to it. This is what the DAC does, and most of our music devices today have one that is already built in to it. It really is a very convenient thing, and it is something that most of us do not even take into consideration when it comes to listening to digital music. This is why I found this article so interesting.
If you are interested in learning more about how DACs work or how to upgrade to a better DAC for your devices, you definitely ought to check out the article that is linked in the first paragraph.
