Herein lies the key weakness with USB-C audio - there is no consistency with how the signal is sent across the USB-C signal, and some USB-C headphones or dongles will not work with some smartphones.

If the data is sent as a digital signal, it will need to be converted to an analog signal before drivers can interpret it. If the signal is sent as an analog signal, a connected pair of headphones can simply carry that signal to its drivers to produce sound waves. With USB-C, audio data can be sent out the port either as an analog or a digital signal. An onboard DAC converts the digital file to an analog signal, sends it through an amp to increase the signal, and then fires it out the 3.5 mm jack to your speaker system, headphones, or whatever else is connected to it. This is the same method used by the 3.5 mm jack (which a handful of smartphones still have).

As many new smartphones no longer carry a 3.5 mm jack, USB-C or Bluetooth are the only ways for these devices to send audio data to external speakers or headphones.īluetooth speakers and headphones contain their own DACs and amps, so they simply take the digital signal sent from the phone, convert it, and push it to their drivers. Let’s look at smartphones as a prime example. This needs to be converted to an analog signal (the black line) before it can be sent to headphones or speakers.

In any case, the digital signal needs to be converted to an analog signal, amplified, and finally sent to a driver to make physical sound.Ĭomputers interpret audio as a digital signal (the blue line). This is primarily due to how a DAC receives the digital audio signal, and it’s why a cheap DAC doesn’t sound good: it results in a phenomenon known as “clock jitter.” A discussion on clock jitter is beyond the scope of this article, but suffice it to say that higher-quality DACs have little to no jitter, resulting in higher audio fidelity and better sound quality. A poor-quality DAC/amp system can make for lousy sound, while a high-quality DAC and amp can pump out high-quality music, speech, or other auditory data.
The DAC and amp are the primary components responsible for audio quality. 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.
