These have drivers that vibrate a membrane (like a piece of special paper) and create the physical sound waves. The analog signal is then sent to an amp, which strengthens the signal and sends it to the speakers or headphones. The DAC is a computer chip specifically designed to turn digital information into an analog audio signal. When you select an audio file to play on your phone or computer, the digital information (the 1s and 0s that make up the file) is passed through an encoder to a Digital to Analog Converter (DAC). Your brain then interprets these vibrations as Beethoven’s 5th Symphony, the Gettysburg Address, or Cardi B’s latest hit single.Ĭomputers work in much the same way as your brain, though they interpret sound waves and vibrations as digital signals. These waves carry the sound to your eardrum and cause it to vibrate. It moves through the medium by traveling along vibrations, which you may know better as “sound waves.” That’s how your computer’s speakers make noise - they vibrate at specific intervals, which vibrates the air around them, creating sound waves. Sound travels through a medium (think of a pathway) like air, water, or something solid like our eardrums.
To understand what USB-C audio is and how it’s different, we need to first understand how a computer interprets audio. But how does USB-C audio (digital) differ from the traditional (analog) headphone jack? Let’s take a look at what USB-C audio offers, as well as some of its drawbacks.
One key feature of USB-C that is used widely on modern smartphones is audio transmission. It can be used to transfer files, connect peripherals like high-speed storage drives, displays, and more. Facebook Twitter Google + LinkedIn Pinterest Email Share.
