The Top 10 Best Audio Interfaces for the Money

Here's an in-depth guide and review of the best audio interface models in the market

Buying the best audio interface is going to help solidify both the power and overall capabilities of your studio, regardless if you’re a professional, semi-pro or even beginner starting to build your new home recording studio. For continued readers of our website, we’ve been able to help many when it comes to choosing which microphones are best; however, we have frequently mentioned the importance and necessity of phantom power and audio interfaces in our studio — not only for recording vocals with our mics but various instruments as well. Due to this, we wanted to create a guide to help those looking to power up their beloved music gear and instruments and get that sound quality we’ve always wanted. Cue in the best audio interfaces, and today we compiled some of our favorites to recommend you.

What is an audio interface?

An audio interface is a device that’s meant to provide power, processing, effects (some, at least), and organization of your many recording devices into one. They act as an ‘external sound card’ if you will, since they’re a lot more powerful, higher in quality, and merely overall better than the sound cards built-in to your computers, regardless if you’re on a PC or Mac. Depending on how you listen to your audio, whether it be studio monitor speakers or studio headphones, most also have outputs to handle this gear in order for you to track and monitor your recordings. Some even provide MIDI ins and outs to allow your keyboards and other controllers to run more smoothly in the recording process (and keep it all organized, too).

In our opinion, one of the biggest and most important parts of an audio interface is the help with the issue of latency. If you’ve ever attempted to record before, whether vocals, guitar or other instruments while going straight into your computer, we’re sure you’ve noticed a slight ‘delay’ — which is one of the most annoying parts of recording and making music, in our opinion. How are we supposed to get that work flow going if we have to try to ‘guess’ when to start playing our gear? Since audio interfaces have are more advanced internal circuitry and overall build than computer sound cards, they can get greatly reduce this ‘lag’ or merely eliminate it altogether.

Selecting the best audio interface

Now that we’ve covered what they are, let’s look into how to buy the best audio interface for you. Since audio interfaces come in many different shapes, sizes and price-points, it’s going to depend on the reader’s needs which we have listed below.

  • Think of what exactly you’re looking to record and hook up to your audio interface. Not only as of today while you read this, but in the future as well. Do you only have one mic, a guitar and a MIDI keyboard? Sticking to a 2-in and 2-out with an XLR input for a condenser mic and MIDI inout will be quite feasible. Are you going to be recording entire bands? Look for more than 22. Perhaps a 66 will be best, or even a 44. Maybe you’re recording multiple microphones at once (the “at once” here is crucial — if it’s separately, you can always get away with just replacing the XLR with different mics as you go)? Look for more than one XLR input in your audio interface. Of course, these examples are subjective, and you may land somewhere in the middle, which we’ll leave up to you to see which is best.
  • What type of connectivity do you want? We have many, and a majority of audio interfaces, providing USB connection. Others (and more towards the expensive and advanced spectrum) can give us Thunderbolt (for Mac only, of course), and even some with FireWire if you want to go heavy. Your computer’s operating system and type will also dictate this decision as well, considering the ports are at times only compatible with the OS. USB of course will span in all directions, and will be best for uses such as in home studios.
  • How much are you willing to spend? The range of audio interfaces is huge, spanning from $100 to $,1000+. This will decide not only how many ins and outs you’ll be getting, but also the overall sound quality you’ll be able to possess for your recordings. For home studios, sample rates up to 24 Bit / 192 kHz will be fine and we wouldn’t recommend going any lower. The $1,000 models start to get into not only higher sample rates but more advanced internal processors, which are usually a concern for professional studios.

The top 10 best audio interfaces

Zoom TAC-2

Our pick as the best audio interface

Check pricingreviews: US | UK

Up first we look at one our favorite models as the best audio interface, the Zoom TAC-2. The Zoom is a 2-in/2-out thunderbolt audio interface that is fairly easy-to-use – all features are controlled by one knob. It comes with a pair of XLR/TRS combo jacks in the back to hook up your mics, instruments, or line signals to the input, while also coming with a front input jack so you can add a guitar or bass without unplugging anything else. While you’re playing, the TAC-2 not only records, but it also has a neat feature that performs four times upsampling of your signal during the analog-to-digital and the digital-to-analog conversion – this means you get minimal aliasing noise and higher clarity. The TAC-2 features Apple’s thunderbolt connectivity — 5 times faster than USB 3.0 and up to 20 times faster than USB 2.0 – which is why it is considered one of the best audio interfaces in the market today. If you need something that is fast, relatively stable, and bus-powered, then the Zoom TAC-2 is your best bet.

Apogee ONE

Another one of our picks as the best audio interface

Next, we have the Apogee ONE, which is one of the best audio interfaces on the go gigs or smaller home studios on a budget. The Apogee ONE is an all-in-one 2-in/2-out portable, USB interface that provides you with everything you need to record – simply connect a microphone, guitar or use ONE’s built-in omnidirectional microphone to capture your music (definitely don’t rely on it for major recordings — you should have a condenser for that). The ONE 2-in/2-out configurations also let you record with a microphone (built-in or external) and a guitar at the same time. It also uses its AD/DA conversion and mic preamp technology to produce solid music, podcast, or voice-over recordings while also still giving you studio quality sound to your headphones for accurate mixing and/or hi-fi listening. The Apogee ONE is compatible with GarageBand, Logic Pro X or any core audio application (Mac or iOS). It comes in two models: ONE for Mac or ONE for iPad or MAC – choose whichever you please.

One of the best audio interfaces for professionals

A rather expensive interface but amazing power and capabilities here

See reviewsprice: US | UK

Here we have another Apogee model, the ELEMENT 24. The Apogee ELEMENT 24 is one of the best audio interfaces if you record on Mac with one or two inputs a time. It is a thunderbolt 10-in/12-out audio interface that is rather cost-effective when comparing it to other thunderbolt models on the market. The ELEMENT 24 features 2 front-panel mic/line/instrument inputs on combi connectors, 2 rear-panel balanced XLR outputs, a 1/4” stereo headphone out, and word clock I/O.

The thunderbolt drivers deliver a relatively low-latency performance (1.41 ms), along with solid stability. The driver also draws less CPU power ranks which lets you run more plug-ins and monitor through your DAW at lower buffer settings. Lastly, the “Element Control” software of the Apogee ELEMENT 24 provides you with remote control of your hardware on your Mac or iPhone/iPad, giving this one a well deserved nod as the best audio interface. There are also a few more options available, such as the ELEMENT 46 or even 88 if you needed more plug-ins.
