The 9 Best USB Audio Interfaces for Musicians

Kris Wouk 25-07-2019

Depending on what kind of music you want to make, you can write, record, and release an album using nothing but your computer. That said, with your computer alone, you’ll be somewhat limited.


If you want to add real-world instruments or voices to your computer recordings, you’ll need an audio interface to record them. USB audio interfaces can cost a pretty penny, but depending on your needs, they can be quite affordable as well.

The Focusrite Clarett 4Pre USB is a successor to the original, Thunderbolt-only 4Pre. This model can work with USB-C or Thunderbolt ports as well as older-style USB 3.0 ports, which makes it a great option if you need flexibility for over which computer you’re using.

This model features Focusrite’s Air-enabled mic preamps for extra high-end presence when you need it. Aside from the four on-board preamps, you also get four more line-in jacks, plus optional ADAT and S/PDIF I/O for a total of 18 inputs and eight outputs.

Putting the terms solo and twin in the same product name seems confusing, so we’ll clear it up for you. The Universal Audio Apollo Twin MKII Solo is aimed at singer/songwriters but features two mic/line preamps. This leaves you one input for your voice and another for your instrument of choice.

You also get a bundle of plugins to make the package even sweeter sounding. There are UAD classic hardware emulations like the LA-2A, 1176LN, Pultec EQP-1A, plus a handful of Softube plugins like Amp Room Essentials. This model even comes with remarkable features like a built-in talkback mic; great for starting a home studio.
