Mac is somewhat of a golden standard in the music production industry, yet somehow a lot of interfaces are missing non-USB connections. The Universal Audio Apollo Twin X DUO is here to change that, providing an exclusive Thunderbolt port to satisfy even the most demanding producers and their iOS devices.

The high-quality audio parallels that of much more expensive audio interfaces thanks to the elite DUO Core processor and Dual Unison preamps. Pair that with the almost-zero latency of Thunderbolt, and you have the future of music-making in your hands.

But another key feature of the Universal Audio Apollo Twin X DUO is its obsession with analog gear. The included bundled software and the versatile preamps allow you to track your inputs through different vintage gear, such as the 610 tube preamp.

  • I/O: 2-in, 2-out
  • A/D resolution: Up to 24-bit/192kHz
  • MIDI connectivity: In/Out/USB

If you're an electronic producer who's not planning to record multiple instrument inputs at once, the Arturia MiniFuse 2 is for you. This compact interface is set on giving you a streamlined workflow, free of distractions and focused on digital music-making.

The combo preamps, however, are there to ensure you get top-notch sound quality whenever you decide to plug in your instruments. One of the best features the MiniFuse 2 offers is the dedicated headphone controls — a perk not too common in this price range.

But the one feature you can't gloss over is the stereo virtual loopback channel, which allows you to capture computer audio at all times. It's rare to see loopbacks in audio interfaces — yet sample enthusiasts and content creators are sure to fall in love with it.

Best Audio Interface Buyer's Guide

Navigating the world of audio interfaces can be quite a challenge if you're new to recording music. Packed with dozens of features, inputs, and outputs, USB audio interfaces are among the most complex pieces of gear in the music world.

But fret not! Here, we've compiled a buyer's guide to help you find a good USB audio interface that'll accommodate all your recording needs. While this doesn't cover every aspect there is to buying a good audio interface, we believe there are four fundamental specs to keep in mind:

Sampling Rate

The sampling rate is the frequency at which the audio interface takes "snapshots" of the sound — you can think of it as how a camera captures video by taking a lot of pictures. These snapshots are then used to recreate the original analog signal in your computer.

While you may think that a higher sampling rate is automatically better, the theory says otherwise. According to a phenomenon called the "Nyquist–Shannon sampling theorem," you only need about 44100Hz to capture all of the audible frequencies at near-perfect fidelity.

Yet, the best audio interfaces nowadays go way over this number, offering up to 192kHz resolution. This helps capture the higher frequencies a bit better, giving your sound that extra professional studio sound. But remember that getting less than that shouldn't pose any major problems!

Bit-depth

If the sampling rate is similar to taking a snapshot, the bit-depth determines the quality of the snapshot itself. In short, the bit rate allows the computer to place your signal on the Y axis, which represents polarity and volume at a very early instance of the analog-to-digital conversion.

A low bit-depth will result in a noisy recording process, as the interface has to go through rounding errors to fit the signal in the given bit range. Going below 8-bit will usually yield completely useless audio files that are not only opaque but also covered in background noise.

Luckily, most modern DAWs and universal audio interfaces can handle upward of 16-bit (the CD standard) by default. Going anywhere over 24-bit is usually overkill, as most recording engineers recognize that 16-bit and 24-bit are enough to capture any signal.

Mic-, line-, and instrument-level inputs

You may have noticed that most modern audio interfaces offer three kinds of inputs: mic-, line-, and instrument-level. The differences between each of these mostly have to do with input gain, as different gear will require different ways of amplification.

Line inputs are by far the loudest, with signals usually being between -10 and +4 dB loud. Line instruments, such as synths, output a signal that's ready to be taken by audio interfaces and require little to no amplification. The same also applies to line outputs.

Instrument inputs, on the other hand, usually oscillate between -30 and -10 dB. Also known as Hi-Z inputs, instrument-level inputs are also equipped with a higher impedance to properly handle the difficulties of magnetic pickups found on electric guitars and basses.

Last but not least, microphone inputs take on signals that are between -60 and -30 dB. These also often come equipped with phantom power — an optional 48v current that powers up certain microphones (usually condensers) without needing external power sources.

Included Software Package

Now, it's easy to gloss over the software bundle included in most USB audio interfaces. However, if you're new to audio recording or a home studio user, this bundle may be just what you need to upgrade your recording space.

Plug-ins, DAWs, courses, and standalone utilities are some of the most common perks included in these bundles. Taking into account that a DAW license or a world-renowned plugin can cost close to a thousand dollars, skipping out on these freebies would most certainly be a mistake.

For example, most Focusrite interfaces (such as the Scarlett 18i20) come with Antares Auto-Tune, Native Instrument Massive, and Ableton Live Lite included. This bundle on its own could cost upward of 200 dollars, making Focusrite products a bargain when compared to its competitors.

Frequently Asked Questions (FAQs)

Do expensive audio interfaces sound better?

As with all things related to music gear, more expensive doesn't necessarily mean better — although it does help. Pricier audio interfaces usually have better A/D resolutions, preamps, converters, and circuits, which help capture your signal with pristine quality.

But, of course, there are exceptions to this. The Behringer U-Phoria UMC202HD, for example, manages to offer top-notch fidelity at a reasonable price. However, this may not be an option for you if you're looking for ample I/O capabilities or other bonus perks.

Should I use a DAC or audio interface?

The answer to this is surprisingly simple: if you're looking to record anything, an audio interface is the right option for you. A DAC (digital-to-analog converter) is used almost exclusively for listening to music, as its only function is to convert digital signals into analog outputs that can be sent to amps and speakers.

However, this doesn't mean that DACs are no good — if you want to have the best listening fidelity possible, DACs can provide astonishing resolutions that audio interfaces can't even dream of. Some DACs offer up to 32bit/384kHz or even 32bit/768kHz!

Do computers have built-in DACs?

Yes, any computer with a speaker has a DAC included. If the computer also allows any kind of input, this would be closer to a built-in audio interface. These are often referred to as "sound cards" — you can think of them as a barebone version of an external audio interface.

So why do producers buy external interfaces? Well, to put it simply, built-in sound cards just aren't enough to record at a high fidelity. The integrated computer interfaces are usually very limited in terms of I/O, audio resolution, and other features key to recording music.

Verdict

We know that buying a USB audio interface can seem like a daunting task — however, understanding a few concepts will help you find the perfect pick for you. The most important things to consider are, by far, the number of inputs and outputs you need to record your music.

Then, you should look into audio resolution, MIDI capabilities, mic preamps, and included software freebies. Some interfaces are focused on minimalist recordings, while others aim to be a central hub for all your music-making needs.

But if you want to get straight to the point, we recommend you take a look at our top pick: the Focusrite Scarlett 18i20. If you're looking to avoid breaking the bank and want to set up a simple home studio, we recommend the Behringer U-Phoria UMC202HD instead.
