What's the Best USB Audio Interface? At-a-Glance

  • USB audio interfaces allow you to run one or more XLR mics into your computer
  • They can offer an increased range of flexibility and options when compared to your typical USB mic setup
  • USB audio interfaces tend to be small, light, and a lot less cluttered than a standard mixer
  • The best USB audio interface for you will depend on your own unique budget, setup, and needs
  • Read on to find out more, and to explore your options

Podcast equipment setups vary from person to person. Some podcasters prefer to keep things as simple and as minimalistic as possible. Others are always looking to add the latest shiny thing to their arsenal of audio gear.

The easiest way to get set up ready to record good-sounding audio is to plug in a USB mic. The quality of USB mics has come on leaps and bounds these past few years. That said, a lot of podcasters feel the desire to “graduate” to an XLR mic after a while, as they begin to explore ways to take their audio quality from good to great.

If this sounds like you, then you might also be in the market for a USB audio interface. Whatever XLR mic you decide to pick up (see our best podcast microphone choices right here), you won't be able to run it directly into your computer.

Of course, you don't even need a computer to run an XLR mic. You could plug it into a digital recorder instead. But if you record online with co-hosts or interviewees, or, prefer to record directly into your DAW, then getting yourself a quality USB audio interface is going to make a lot of sense.

What is a USB Audio Interface?

A USB audio interface is a little box that you can plug an XLR mic into. Sometimes, depending on the model, you can plug multiple XLR mics in.

A USB audio interface will connect to your computer by – funnily enough – USB. This type of setup gives you a lot more control and flexibility than your typical straight-up USB mic setup.

You'd also plug your headphones into your USB audio interface. It becomes both your input and your output. You simply need to select both these options when setting your preferences in your DAW or call recording software.

USB audio interfaces tend to be smaller and lighter than your average gaming console. They're typically free from too many knobs and dials, and look a lot simpler than their mixer counterparts.

zoom podtrak p4

Zoom PodTrak P4 – The Versatile Option

  • Cost – $199/£199
  • XLR Inputs – 4
  • Size – 112mm x 155mm x 47 mm
  • Weight – 290g

A new kid in town, the Zoom PodTrak P4 is a podcast-specific digital recorder which also doubles up as a USB audio interface. This means you'll be sorted to record up to four local participants and remote guests whether you're at your computer or not. Obviously though, with more options comes more complexity, which might put beginners off.

It's worth mentioning that, when used as a USB audio interface, you don't have the same multitrack options as you do when recording directly to the SD card. However, there's nothing to stop you doing both at the same time!

As I've said already, the best option for you is going to depend on your own unique needs, setup, and budget. By looking over the input options, price ranges, and listening to the sound samples, the chances are you'll have made your mind up by now.

For the vast majority of podcasters, based on the above, it's going to be a toss-up between the Focusrite Scarlett 2i2 and the PreSonus AudioBox 96.
