Recording high-quality voice overs for your eLearning course from the comfort of your home can be rewarding and intimidating all at the same time.

Content creators like you have a wide range of options when it comes to the ideal recording equipment.

In this article you’ll learn about using a mixer vs audio interface for recording eLearning voice overs.

While there’s no doubt choosing the best voice over microphone is a stepping-stone to recording the best voice overs, your microphone is no use if you don’t have a solid audio interface to plug it into.

Let’s start with discussing what an audio interface is and go through some top picks, then we’ll get into the mixers.

What is an Audio Interface?

In the simplest sense, an audio interface is a device that connects your microphone to your computer.

While most computers come with a built-in audio interface allowing you to plug in a microphone with a 3.5 mm pin, the quality of recording you’ll get from that usually isn’t good enough for eLearning voice overs.

A simple yet major mistake that many course creators make is to splurge on a premium-quality microphone but end up going for a sub-par audio interface (or none at all). It’s a common mistake, but at least one you’ll notice right away when you hear the poor quality of your first voice over recordings.

Audio interfaces come in a variety of shapes and sizes along with a variety of features.  Connecting an audio interface to your computer is no big deal; you can simply use a USB or a FireWire – and enjoy producing professional-level recordings.

In addition, they also usually have a microphone preamplifier to amplify the microphone’s signal to produce even better quality sound. The preamp translates the mic’s signals into a language your computer understands.

What Are Audio Mixers?

You’ve just learned a little about audio interfaces, now let’s get into mixers. An audio mixer is a device that serves a more complicated and advanced purpose compared to an audio interface.

Mixers allow you to manage the signals sent to your computer. If you want more control over your recording experience, you may consider adding an audio mixer to your home recording package.

A mixer features equalizers and volume faders for each of the input channels, allowing you to gain maximum control over the sounds entering your computer system. Most mixers also enable you to benefit from unique effects, including delay, chorus, and reverb.

The majority of audio mixers available on the market today come with a USB or FireWire. That means you can connect the mixer to your computer, eliminating the need to buy an audio interface. So you just need to decide between a mixer vs audio interface; you don’t need both.

Mixer vs. Audio Interface

If you’re just starting out creating eLearning courses, chances are you’ll want to buy something that’s basic and affordable. Voice over recording really doesn’t require many of the advanced functions that an audio mixer offers.

If your only goal is to produce high-quality voice over recordings, then you may want to go with an audio interface. I use and recommend an audio interface and not a mixer. As mentioned, the one I use is the Focusrite Scarlett 2i2. It’s affordable and works out well for my needs. I think it’ll work out well for yours too.


To settle the mixer vs. audio interface debate, I recommend going with a mid to high-grade audio interface. It’ll allow you to start recording with minimal hassle. However, if you have the budget and even more importantly, the time to experiment, you may consider a mixer.

While a good audio interface helps you produce clear, rich, professional-level voice over recordings, an audio mixer allows you to play with advanced features and discover what they can do to transform your recordings. It’s not something I’m into as I prefer to plug-in my equipment and then just leave it be, but it may be for you.

Another resource you may be interested in is a complete home recording studio package for the production of eLearning courses. There are several pieces of equipment you’ll need to produce high quality voice overs for your courses, but you can probably get by for less than you think. Take a look!
