1. Focusrite Scarlett 2i2 3rd Gen

The Focusrite Scarlett 2i2 3rd Gen has been the top-selling recording interface for a few years. This is not surprising, as the Scarlett offers an unparalleled balance between cost and benefit.

It doesn’t hurt that it is made by one of the most legendary names in audio, Focusrite. This is our pick for the best two-channel interface in this list.

Focusrite Scarlett 2i2 Studio (3rd Gen)

The Focusrite Scarlett 2i2 Studio recording bundle gives you a great front end that includes everything you need to record.

Why We Love It:
  • Super-low latency
  • Intuitive halo feature
  • Simple, compact, and eye-catching design 
View Price On Guitar Center View Price on Sweetwater


  • High-performance 24-bit/192kHz converters
  • 2 balanced line inputs, suitable for connecting line-level sources
  • Unique, intuitive halo level indicators for optimized gain staging
  • Direct Monitor circuit for monitoring your input with guaranteed low-latency
  • Balanced TRS L/R monitor outputs with level control


The third-generation Focusrite Scarlett 2i2 features two upgraded Scarlett mic preamps, high-performance 24-bit/192kHz AD/DA converters, optimized preamp gain structure, low latency, and instrument inputs that can handle hot sources.

To top it off, the mic preamps now come with Focusrite’s Air mode which provides the Air effect modeled on the company’s legendary ISA console transformers to provide your voice and instrument recordings a brighter, more open sound.

This interface runs on USB bus power and features two mic/line/instrument inputs for simultaneous recording and playback of up to two channels. All of this with independently controllable headphones and monitor outputs.

In a direct answer to its customers, Focusrite added compatibility for iPad Pros with USB-C ports. Just plug into your compatible iPad Pro and open your music-making app. It doesn’t get any easier than that!

The Scarlett 2i2 also features halo indicators to let you know when your signal level for recording is optimal. If the halo is red, your signal is clipping, and you need to cut back on the gain.

The halo will momentarily turn amber as the level becomes acceptable at which point it will turn green. This ensures you will always be recording at the optimal level!

This interface is also great for mobile recording and comes with a comprehensive software bundle headlined by Ableton Live Lite and the Pro Tools First Focusrite Creative Pack. You also get Softube’s Time and Tone Bundle, the Focusrite Red Plug-In Suite, and access to the Focusrite Plug-in Collective.

This makes the Scarlett a fantastic choice for beginners looking for their first interface.

2. Universal Audio Apollo Solo Heritage Edition Thunderbolt 3

For decades, Universal Audio has been the maker of some of the most revered pieces of audio equipment in the world. From compressors to limiters and preamps, UA gear holds a special spot in the audio world.

Their Apollo series of interfaces are nothing short of impressive, with not only fantastic preamps and overall features, but an ecosystem of modeled plug-ins that rival the originals they are based off.

The UA Apollo Solo Thunderbolt 3 is our premium choice for this list.

UAD Apollo X4 Heritage Edition Thunderbolt 3 Audio Interface

The Apollo x4 Heritage Edition comes with a premium suite of 10 award-winning plug-ins, along with the Realtime Analog Classics Plus bundle, arming you with accurate emulations of vintage analog hardware.

The UA Apollo Solo features pair of Unison mic/line inputs, an instrument input, two analog outputs, and a high-quality headphone output.

This game-changing audio interface is compatible with UA’s free LUNA software. LUNA is a complete music production environment for tracking, editing, and mixing with ultra-tight hardware/software integration.

(For a complete overview of what makes LUNA so unique, make sure you read our review of UA LUNA here!)

It allows you to take control of your interface’s monitoring, talkback, and headphone systems, track and overdub with UAD DSP-accelerated plug-ins in real-time, and benefit from full software-based control over Apollo’s Unison mic preamps, without leaving your production software.

Another breakthrough feature that Universal Audio includes with audio interfaces is the UAD-2 processing power. It allows you to take the processing load off your computer and instead be handled by UAD’s super-powerful Analog Devices SHARC processors.

Universal Audio’s Apollo Solo interface has one of these SHARC processors built-in, which gives you enough power to track small sessions and start building your mix.

The UA Apollo Solo is a Thunderbolt 3 audio interface. UA also produces an Apollo Solo with USB-C instead. However, thunderbolt is one of the most important technologies to impact audio production in years, and UA was one of the first to adopt it.

It provides extremely fast connectivity, lower latency, and greater stability than USB or FireWire, with the convenience of a single cable. With the Apollo Solo’s Thunderbolt 3 connection you will be able to run projects with high track counts at incredibly low latency.

Additionally, this interface comes with the renowned UAD Powered Plug-ins bundle. The UAD platform features superb processing power that has made these plug-ins so popular among discerning professionals.

With the Apollo Solo Heritage Edition, you’ll get a premium suite of five award-winning plug-ins:

  • UA 1176 Collection with three unique versions: Rev A, Rev E, and AE

  • UA 610 Tube Preamp & EQ Collection including the legendary Wally Heider “Green Board,” used to record Neil Young, Ray Charles, Elvis Presley, and Jimi Hendrix

Simply said, the Universal Audio Apollo Solo offers unique features and is often the choice for top engineers on the go.

  • JFET instrument input
  • Class-leading conversion
  • Ultra-low latency performance

All you have to do is press the Smartgain button and choose the channels you want to use to record. Once you start playing, singing, or speaking into your microphone, the Smartgain function will automatically set the input level.

If you live stream, then the Audient EVO 4 has a loopback functionality that will be of great help. It lets you blend your mic or other input signals with the output from your computer, then sends the blended signal back to your computer.

This significantly simplifies recording your computer’s output for streaming purposes.

This 2 channel interface also includes the EVO Control app, compatible with both macOS and Windows. This app lets you make easy adjustments to the EVO 4’s hardware directly from your computer, enabling you to set and monitor levels, mute microphones, activate Smartgain, and more without even touching the audio interface itself.

The Audient iD14 features a Scroll control ID mode, which makes controlling your DAW a more streamlined experience. This interface comes with an endless rotary encoder which you can assign using the illuminated buttons and set it to speaker or headphone control.

Other features include Mono sum, Talkback, Polarity reverse, and Cue-mix monitoring, all assignable to the previously mentioned scroll feature.

There are two combined XLR/TRS inputs and two jack outputs, as well as a JFET DI out and a headphone auxiliary out.

The JFET DI is engineered in the same way as a standard valve amp input and guarantees that the signal is matched to your instrument for optimal recordings. It also gives the Line-in tone coloration, adding a vintage amp vibe.

The I/O on the Audient iD14 is expandable because it has an optical input that works as a regular S/PDIF but supports ADAT (Alesis Digital Audio Tape). That allows you to connect further preamps if you wish and can be expanded to a ten-in, two-out interface.

The iD14 is built with a robust all-metal shell and a brushed aluminum finish, making it quite durable as well. Overall, this is a fantastic choice for a small desktop audio interface.

5. Native Instruments Komplete Audio 2

The Native Instruments Komplete Audio 2 interface is the bigger brother of the Audio 1. These are two entry-level audio interfaces created for beginners interested in music production and recording.

The Komplete Audio 1 and Komplete Audio 2 are both 2-in/4-out bus-powered USB 2.0 boxes, differing only in the nature of those ins and outs. For simplicity, we’ll focus on the Audio 2 in this write-up.

With this interface, you can simultaneously record two mics, bass and guitar, the left and right outs of a synth, etc. The latency is in line with a typical USB 2.0 interface, from 7.55ms round trip at 44.1k Hz with a 32-sample buffer, to 51.8 ms at 1024 samples.
