If you’re an experienced podcaster, music-maker, or do high-quality content creation of any kind, audio interfaces are more than likely a de facto component in your audio chain.

But for the uninitiated, what are they exactly, why do you need one, and most importantly, (whatever your experience level) -- where can you find a deal on the best audio interfaces 2021 has to offer?

Get the answers to these burning questions and more below.

What’s an Audio Interface?

Put simply, an audio interface is a tool that routes audio in and out of your computer or mobile device. However, there’s a lot more to it than that.

It does this by using analog to digital converters on the inputs and digital to analog converters on the outputs.

Sound is picked up by your mic as analog, the converters in your audio interface turn it to digital in a way your computer understands, then it reverses the process when playing back to you.

“Sounds fancy, but why can’t I just use the internal microphone on my 27-inch, 3.8GHz iMac?”

Good question and there are two reasons why you can’t.

First, the audio capabilities of your computer just aren’t built for the level of quality that most content creators crave. They’re made to function, function well, but no more -- regardless of price point.

Second, the internal audio capabilities are limited. For recording music, broadcasting, podcasting, etc. you need more control and versatility.

Bottom line -- an audio interface will always produce better sound quality than your computer’s built-in microphone and headphone jack (yes, even if you already have the latest version of your favorite DJ’s DAW of choice installed).

What to Look for in Audio Interfaces

Today, most audio interfaces offer a certain level of quality that you can expect, especially here at Moment.

One thing you want to ensure is that your audio interface supports 24-bit conversion and at least 44.1kHz sample rate or higher for accuracy.

Another important consideration when shopping for audio interfaces for PC or Mac is its connection format to your computer, with USB 3.0 and thunderbolt being the most common -- Just make sure you buy one that fits your rig.

Also, double-check the input and output connections on your audio interface + the number of channels.

The input connections allow you to get signals into the interface. You may need line-level inputs for audio gear, instrument inputs, and digital inputs for expanding the interface with more gear.

For the output connections, you’ll need line-level outputs for routing external audio processors like monitor outputs for studio speakers, headphone outputs for headphones and earbuds, and, of course, digital outputs for routing MIDI equipment.
