If you’re a guitarist looking to record your music and share your six-string skills with the world, you’ll need one of the best guitar audio interfaces to get the job done. For the uninitiated, an audio interface is a device which allows your guitar to communicate with your computer, allowing you to record your playing and even flavor your tone with effects conjured from inside your computer.

Once upon a time, great-quality guitar interfaces were only accessible inside souped-up recording studios, but thanks to a slew of technological advancements in recent years and a market shift favoring hobbyist and at-home guitarists, such devices are now widely available, and accessible to players with a variety of budgets.

But with a greater number of options comes greater difficulty in choosing the best guitar audio interface for your needs. Fortunately, here at Guitar Player we’re no strangers to guitar recording, and we’ve compiled a list of the top audio interfaces available in today’s market.

We’ve taken into account a range of factors, including sound quality, ease of use, and overall value for money, so you’re certain to find the perfect interface for you.

Priced under $200, the 2-in-2-out USB C-powered iD4 MkII houses Audient’s decades of technological and design expertise, featuring an instrument DI input for your guitar, in addition to a mic preamp so you can record the speaker cone of your guitar amp, too.

How to choose the best guitar audio interface for you

You can trust Guitar Player. Our expert reviewers spend hours testing and comparing guitar products so you can choose the best for you. Find out more about how we test.

It’s easy to get lured in with all the additional bells and whistles when it comes to buying the best guitar audio interface for you, but ultimately your biggest consideration should be your input and output requirements, or, the number of inputs and outputs you need to achieve what you’re trying to achieve. For example, if you’re a solo guitarist happy to work primarily on your own using overdubs, you probably don’t need to spring for an interface with many inputs, as most of the time they’ll go unused. 

And on the subject of ins and outs, you should consider whether you’ll primarily be recording direct in with a ¼” guitar cable, micing up a guitar amp, or a combination of the two. If you will be recording with a mic, pay attention to the quality of the preamps in your interface of choice. This could be the difference between average and great recordings.

If you have the money to spend on a more mid-level or higher-end interface, it’s better to go for a better-quality model with only one or two inputs. Price is often dictated, in part, by the number of ins and outs, so buying an interface with more than you need will eat into your budget needlessly.

Next up in your buying considerations should be sound quality, or more specifically, the quality of the components (preamps and converters, for example) housed within. In general, it’s best to look for an interface with a high sampling rate and bit depth, as this will directly translate to the improved quality of your recordings. You should also ensure that your audio interface of choice has low latency. This is, in general, a standard across the recording world, but it’s still important to do your research and confirm, as trying to record accurate tracks with high latency is a terribly frustrating endeavor.

And finally, paying attention to the brand of audio interface will pay dividends. Generally speaking, the big players here – Focusrite, Universal Audio, SSL – have the reputations they have for a reason, so shopping where others have before is often a pretty safe bet.
