Question: What is the difference between an audio interface and a DAC (digital-to-analog converter)?

Answer: When getting into streaming, podcasting, or recording, it may be confusing to narrow down the difference between an audio interface and a DAC. Many use these terms interchangeably, as they both deal with the conversion of audio, however we are often asked what makes these different. With this article we hope to explain the difference between the two and which one may be the right choice for you.

An audio interface is ideal if you are looking to connect an XLR-type microphone to your computer. Audio interfaces will often have one or more XLR/Mic inputs, phantom power capability, and gain adjustments that will accept a wide variety of microphones. Audio interfaces will also have headphone and speaker outputs to allow the user to connect studio headphones and/or studio monitors. An interface takes the analog signal from the microphone and converts it to a digital signal that is sent out (usually by USB) to the computer. This is exactly what you will need if you are looking to get into podcasting or recording, as you’ll need a way to convert the microphone audio to digital for the computer to recognize it. Audio interfaces come in a range of prices, with more expensive units usually including more inputs and outputs, additional software, and higher-quality built-in mic preamps.

A DAC (digital-to-analog converter) takes the digital signal from your computer and converts it to an analog signal that can be sent to devices such as a headphone amplifier or powered speakers. A user may find this useful as many built-in soundcards in computers are not of the highest quality and may produce noise or artifacts that can be heard by the listener. A DAC will convert computer files and reproduce the audio at the highest quality possible. The AT-DAC100 is a current DAC that Audio-Technica manufactures, and you can find more information about the features here.

To conclude, audio interfaces are tools designed for creators (such as streamers, podcasters, and recording engineers), while DACs are intended to be used by listeners.
