What is the best audio interface?

Every computer needs an audio interface. It provides the basic input and output connections for musical equipment, increases the quality of the recorded sound and makes virtual instruments and effects usable in real-time.

They are usually in the form of a USB connected box and have a range of sockets for plugging microphones, guitars, synths and other line-level sources. You’ll get hands-on gain controls, level metering and the ability to turn your computer into a studio. The sound quality of minijack inputs is not going to cut it when you’re trying to produce music. You need real connections that the rest of your music gear will appreciate.

There are many audio interfaces out there with a wide range of features and connections. The ones we’ve featured here are going to do a fantastic job of connecting your gear and creativity to your computer. Many of them have different versions with varying selections of inputs and outputs. You should choose the one that best fits the sort of equipment you want to plug in.

Our picks for 2022‘s best audio interfaces include:

  • MOTU M2 and M4
  • Audient EVO 4
  • M-Audio Duo
  • Audient ID14
  • PreSonus Revelator io24

First, some FAQs:

Audio Interfaces Q&A

Do I need audio interface for home recording?

Robin Vincent

Yes, you do because without one you’ll find that recording onto a computer using the built-in sound facilities sounds terrible and can be very frustrating. An audio interface will give you the proper connections for microphones, guitars and keyboards. It will help you capture a great sounding performance and give you the full potential of your computer’s music-making ability.

So if you want to record, get an audio interface.

Which audio interface is best for music production?

Robin Vincent

You need to look at what you are trying to achieve and how much money you have. In our list, we have a range of audio interfaces that would be awesome for home recording so you can’t go far wrong. You have to consider whether you want something in a flat format or more of a desktop unit. How many mic and instrument inputs do you need? Do you want to set it all up manually or would you like help with levels and monitoring? Then check out the software bundles to see if there’s something there you can really benefit from. Only then will you know which is the audio interface for you.

Does music sound better through an audio interface?

Robin Vincent

Yes, undoubtedly. The sound output of a computer is designed for games and video playback and so is set up to make those things sound good. For music making you want a much cleaner, flatter sound so you can hear individual instruments better and mix them appropriately. An audio interface is designed to give you a great dynamic range and low noise output which is perfect for mixing.

Best Audio Interfaces

The best place to start. These interfaces are all you need to kick off your home studio.

MOTU M2 and M4

Usually known for their high-end audio interface, MOTU has pulled some of the key features and their expertise across to a pair of budget audio interfaces that raise the bar on what home studios should expect from their gear.

They are a good size, made of metal with the usual ins and outs you find on a 2 in/out and 4 in/out budget interface. But there are a few added features that make all the difference.

First of all, that display is gorgeous. On most interfaces, you’re lucky to get a clip light, whereas here you can actually see the level coming in and going out and use it to properly adjust the gain. Both mic preamps have individual +48v phantom power switches which are unusual on interfaces at this level. So you can power a condenser mic on one input and use an unpowered dynamic on the other.

They also have individual monitoring buttons so you can mix and match between direct and software monitoring — direct on your voice while your guitar goes through a software amplifier.

The sound quality, headroom, and dynamic range are excellent up to 192kHz. The latency is also very low and performs brilliantly. There’s an extra feature in the driver which creates a virtual loopback function where you can record the output of your software straight back in again. This is perfect for podcasters and video streaming. And to round it all off the outputs are DC coupled so you can route CV out to modular synthesizers.

The M2 and M4 are very capable interfaces with a great feature set that beats most other interfaces on the market. Although M4 goes just slightly over our $200 budget threshold, both are highly recommended.

Street Prices:
MOTU M2 – $199
MOTU M4 – $269

Audient EVO 4

The EVO 4 is an unusual looking audio interface and probably the easiest one I’ve ever used. It has a big knob with a halo of LEDs, a couple of buttons and a handful of connections. What’s brilliant about it is that you can plug it in, plug in your mic and start recording in seconds with hardly any setup or messing about.

It has 2 in and 2 out. You can plug two microphones in the back and swap out one of those for a guitar input on the front where you’ll also find the headphone output. +48v phantom power is available for both inputs via a button on the top. The big knob provides level control over the output and monitors the inputs. It’s all very straightforward.

The secret weapon of the AVO 4 is the big green button. Pressing it activates “Smartgain” which is the most useful feature ever invented on an audio interface. With Smartgain activated you sing into your mic or play your guitar and over a period of about 10 seconds it analyses the audio and sets the perfect recording level. It’s like doing a tiny sound-check. You are then ready to record confident that you are not going to be too loud to cause distortion or too soft so you can’t be heard. Smartgain gets it right every time – it really does.

The EVO 4 also comes with some really good monitoring and mixing software which gives you full control over all the levels in and out plus the ability to loopback so you can combine the playback of software with your input for live streaming or recording into something else.

It’s an impressive and remarkably priced little plastic box. If you need a few more inputs there’s the larger EVO 8 that does everything the EVO 4 does just with more connections.

Street Prices:
EVO 4 – $129
EVO 8 – $199

M-Audio M-Track Duo

The M-Track Duo is undoubtedly the cheapest audio interface I’ve come across that’s actually good enough to hold its own in this list of “Best audio interfaces”. There’s also a Solo which is even cheaper but for this sort of money it’s worth getting the slightly bigger Duo.

The M-Track Duo has very familiar features with a pair of mic preamps on the front that can also handle guitar or line level. There’s phantom power for the mics, a headphone socket and a direct monitoring option. On the top you get level control on the inputs and outputs. The knobs are slightly sunken into the box which offers them some protection from accidental knocking.

It’s a simple, straightforward audio interface with no hidden powers or special features but it works brilliantly. Usually interfaces around this price have poor drivers and poor audio performance with software but these are great. Good low latency, low CPU, decent quality sound. Bear in mind that the recording quality is only 16-bit and up to 48kHz but that’s good enough for a home studio.

The price does bring some compromises; it’s lightweight and made of plastic, the headphone output is a little weak and it doesn’t sound quite as good as the other interfaces on this list but for the price it’s awesome. Comes with a decent bundle of software including Pro Tools First so it’s all you need to start making music.

Street Prices:
M-Track Duo – $69
M-Track Solo – $49

Audient iD14 MKII

Audient’s ID range of audio interfaces are a step-up from most home studio solutions. The ID14 MKII is a bit of a sweet spot for me in that it offers pro-quality recording and features without overloading you with inputs or taking up your desk space. What you get is a perfectly balanced interface with professional quality form and function.

The 2 microphone inputs on the back are based on the preamps from Audient’s professional high-end consoles. There’s also a separate JFET guitar input that enhances the tonal qualities of your guitar when plugging directly in. Gain is provided by knobs on the top of this desktop-based interface and each channel has a separate switch for phantom powering condenser mics. On the back, you get two pairs of outputs for sending to different monitors and on the front are two headphone outputs which are awesome for when you’re collaborating. It also has an ADAT digital input if you wanted to expand into recording bands.

The big knob on the top is a very useful multi-functional device. It can control the output volume and the headphone levels separately but with the touch of a button, it can become a scroll wheel, synth controller or automation creator right within your DAW. And talking of software the ID14 comes with some excellent monitoring software where you can visually monitor all the inputs and outputs and create internal routings. The included Audio Loopback driver means that you can capture the output of one piece of software and route it into another. Perfect for podcasting or for routing the output of your DAW into live streaming software.

The Audient iD14 MKII is a class act and there’s a smaller version in the iD4 MKII if it’s just you and a guitar which is even more affordable.

PreSonus Revelator io24

This is quite a strange-looking box but the design is a well thought out response to the fiddliness of many of the traditionally shaped audio interfaces. The front panel of the Revelator angles up to give better access to the two mic sockets, display and controls when it’s sitting on your desktop.

The Revelator io24 is designed with both studio recording and live streaming in mind and so it has some extra features that are going to make streaming a breeze. On the front, there are a pair of inputs with digitally controlled, low noise XMAX-L mic preamps that can also double as instrument inputs. On the back are a pair of outputs, a headphone output and a very useful MIDI In and Out port. The inputs are controlled and monitored on the interface using the rather nice color display and illuminated encoder.

Behind the scenes is some DSP processing that’s going to make the Revelator stand out. For each input you have StudioLive Fat Channel Processing that is going to infuse your sound with classic audio treatments including compression, expanders, limiting, EQ, high pass filtering and a noise gate. Add to that a range of vocal effects including reverb, delay, detuning, doubling, vocoder and comb filter. It comes with plenty of presets tailor-made to give great results. Some are just for fun but the Fat Channel and reverb are really going to up your game when recording, performing and live streaming.

On the streaming side, Revelator has 2 stereo loopback channels for pulling different bits of audio software into the Digital Loopback Mixer. SO you could have the output of your DAW and playback from videos running into the mixer and out to your live streaming software. But that’s not all, with a click of a button anything going through the mixer can be sent direct to your streaming software without having to worry about routing or configuration.

Revelator io24 comes with Studio One Artist for a complete professional recording package in the one box. It’ll work with macOS, Windows and iOS and can even run the PreSonus UC Surface remote control software to control it from an iPad, Android if Windows device on the same network.

Universal Audio Volt 276

Universal Audio has released a range of Volt audio interfaces to match every budget and application. The Volt 276 looks like the sweet spot to me with enough inputs for collaboration, the form factor that sits pretty on your desk and the quality that’s going to give you stunningly authentic professional sound.

With the wooden ends and stylings of the Volt 276 give it a deliciously vintage vibe and that’s definitely the intention. It has a very familiar set of connections with twin mic preamps on the front that also take instruments and a pair of monitoring outputs on the back. The MIDI In/Out ports are very welcome and so is having the headphone output on the front with its own volume control. All the important controls are on the top which is always my favourite way of doing things with a desktop audio interface. A nice big monitor control knob, individual gain knobs for the inputs and very clear input and output monitoring.

The special sauce of the Volt 276 can be found in the Vintage Mic Preamp Mode and onboard 76 Compressor. These are not software plugins, they are analog circuits built into the interface to offer a rich, full sound of high-end hardware right inside your home studio. The Vintage Mic Preamp mode uses innovative solid state electronics to emulate the tube sound of the Universal Audio 610 tube preamp. The compressor is inspired by the UA 1176 Limiting Amplifier and is perfect for keeping voices under control and adding punch to synths, guitars and drum machines.

Volt 276 comes with a large suite of software including Ableton Live Lite and some really nice plugins but with the Volt you come for the sound, not the bundle.

Arturia AudioFuse Studio

If you’d like something a bit more versatile on your desktop then check out the AudioFuse Studio from Arturia. Following on from their excellent AudioFuse audio interface, this pushes the I/O further and offers more hands-on control.

It has 4 world-class microphone preamps and a phono preamp for sampling vinyl. It has Bluetooth audio streaming to your monitors or into your DAW. It’s on USB-C connectivity and also has ADAT expandability along with MIDI I/O and Wordclock to give up to 18 inputs and 20 outputs.

There are two monitor outputs and a hardware button to switch between speakers. There’s a dedicated re-amping output so you can record your guitar and then tweak the sound through your amplifier later. There’s even a USB hub built in for your dongles or MIDI controllers.

The design is hand and finger-friendly and completely intuitive. There’s also a versatile software mixer that mirrors the hardware and lets you save configurations. It comes with a great bundle of software effects and virtual instruments. At $999, it’s at the higher end of the mid-range but it’s a very versatile device for a project studio.

Street Price: $999

Focusrite Clarett 4Pre USB

Focusrite make a lot of audio interfaces but the Clarett range brings their A-Game to the table and the 4Pre offers their best combination of connections, price, quality and expandability. Initially only available on Thunderbolt the 4Pre USB opens it up to a wider range of systems.

You’ve got 4 professional quality mic preamps right on the front with hardware gain controls, halo LED monitoring and phantom power per pair. With Focusrite’s Air technology and impedance switching your mics will sound better than they ever have with breath-taking colour and high-end detail. On the back there are a further 4 line inputs which are perfect for bringing in hardware synthesizers and keys. There’s full control on the front with the nice big monitoring knob and two independent headphone outputs for when you’re working with someone.

The Clarett 4Pre USB is also expandable via optical ADAT connection to any ADAT preamp to give it a total of 18 inputs should you ever need it. You’ve also got a useful MIDI In and MIDI Out which should never be undervalued.

It comes with some useful monitoring and mixing software and a bundle of plugins, instruments and Ableton Live Lite to get you started.

The 4Pre is a fantastic sounding interface and would look magnificent in any home studio.
