Now without further ado, let’s get rolling!

Introduction

You may have been like me and thought to yourself, “What the heck is an audio interface?” The term sounds really intimidating, at least for me it did.

It was Spring of 2006, and I wanted to get into recording. I took an electronic music course and had a lot of fun with it, while also learning about all kinds of weird terminology. Wait just kidding I didn’t learn anything. Lol.

I mostly just got by that semester, while still making some decent music. The problem was that I didn’t utilize all of the tools that my professor asked. Thus, I got a C instead of an A or B.

Still, I had a lot of fun in the studio after hours, and got spooked out a couple of times. There’s something really eerie about recording music in a quiet room with no one around at dusk.

My Experience

A number of years later, I contacted that same professor to ask him some advice on how to hook up a MIDI device to my computer. What is MIDI?

He suggested an Audio Interface. What? “It’s a device meant to convert digital sound into analog, and vice versa.” Huh? “It’s a soundcard.” What?

“Say what again! I dare you, I double dare you mother f*cker! Say what one more time!”

Lol he didn’t actually respond to me like that, but Samuel L. Jackson might have. 😛 What is a soundcard?

“See there’s this invention called the computer, and on this invention they process processes.” Bleh.

No really, you know the internal sound card inside your laptop or PC? The crappy one that enables music to play from your laptop speakers? Think of an Audio Interface like that, except you can see it, it’s in the form of a neat little box, and the quality is light-years better!

Whew!

What does an audio interface do?

Glad you asked.

In simple terms, it converts the signal from your microphone into data that your computer can process, and then spit back out at you through your studio monitors, or speakers, for you to hear. What are studio monitors?

A more in depth discussion on this exchange that can be found here:

  1. Bit depth vs. Sample rate.
  2. Your audio interface

So basically, an audio interface:

  1. Converts data into language that your computer (and you) can understand and process.
  2. This is done through A/D (analog to digital) converters, which capture and quantize this information (your voice) in the form of 1’s and 0’s. It basically makes copies of the info and then sends back these copies to you so that you can hear them. What you receive back is an exact (in theory) replication of the original sound.

An Audio interface can also:

  1. Hook up your Studio monitors. But not by themselves, because they’re inanimate objects 😛
  2. Enable you to use a MIDI device such as a MIDI keyboard.
  3. Power a microphone with the 48v on board phantom power and mic preamps. Preamp vs. Interface.

My Top Recommendations

Focusrite Scarlett 2i2

Focusrite Scarlett 2i2

One interface that has remained rock solid for me since 2014 has been the Focusrite Scarlett 2i2. Yes, the hype is real. Is it overrated? Sure, but overrated simply means a lot of people have used it (and for good reason). It’s simply a reliable and worthwhile investment.
