best-audio-interface-reviews-2017-main-imageA poor standard recording can’t be saved “in the mix” so it’s important to have the right gear to do your music justice.

A key part of the recording chain is the audio interface, and in this post we take a look at the top audio interfaces on the market right now.

We’ll start by giving an outline of what an audio interface does, and highlighting the things you should be looking for before you buy. If you’ve heard it all before then jump straight to the reviews of our favorite audio interfaces.

What Exactly Does an Audio Interface Do?

The audio interface is quite simply the hub that allows you to connect your audio equipment to your computer. Home computers typically don’t have the necessary ports to allow your instruments and microphones to be connected, and this is why a good interface is essential.

An audio interface connects to your computer using USB, Firewire, or Thunderbolt and translates the analogue signals of your instruments into digital ones and zeros ready to be read by the computer. It also works in the opposite direction and turns computer signals into audible ones for you to hear.

Now, you might ask why you might need one when USB microphones are readily available. Plus, every home computer has a sound card. Well, the answer is sound quality. Any musician seeking a professional level of recording quite simply needs a decent audio interface. The audio interface acts like a purpose built sound card complete with inputs/outputs, gain, phantom power and all the tools required to make a high quality recording.

audio-interface-diagram

The diagram above shows an audio interface with two mono inputs. This can handle two instruments like a guitar and microphone, or one stereo instrument. Audio interfaces come with different numbers of inputs and this should be one of the main considerations when looking for the right one for you. We’ll go into more detail about what else you should be looking for in the next section.

9 Things to Look For in an Audio Interface

Audio interfaces offer a lot of different recording options. They determine the quality of the recording (bit depth & sample rate), the number of instruments that can be recorded at once, the type of microphone you can use (does it have phantom power?), and how you listen to your recordings. In this section we’ll explain the common features of an audio interface, so you can make an informed choice. Here are 9 things to look for….

  • Bit Depth

Bit depth is the number of bits of information that is held in each sample in your recording. It represents the resolution of your recording.

In mathematical terms 1 bit = 6 dB. Your standard CD quality audio is recorded at 16 bits. This gives it a dynamic range (like the range of volume) of 96dB. As this includes digital noise, the dynamic range that is left is not that big. This means that quiet sections of audio might not be as clear as you would like. 24 bit audio is commonly used in professional recordings as it gives a much bigger dynamic range. This means higher resolution, clearer music. A larger bit depth allows more date to be captured to re-create the audio more accurately.

Good audio interfaces will allow a bit depth of 24 bits. If you want crisp and well defined recordings then 24 bits is a must.

  • Sample Rate

The sample rate is the number of samples of audio taken each second. The CD standard is 44.1 kHz meaning that 44,100 samples of audio are carried each second. The highest frequency of sound that is produced in the audio is equal to 1/2 the sample rate.

Highest Recorded Frequency = 1/2 Sample Rate

This means CDs are capable of reproducing frequencies only as high as 22.05 kHz. Now, as humans our hearing range is limited from 20 Hz to 20 kHz (only the very best ears will manage this), so you may ask why sampling rates above 44.1 kHz would matter. If the sample rate is too low then distortion might occur (aliasing). Also, these high frequencies that are above the 20kHz limit of human hearing can interact with lower frequencies to give subtle audio effects.

The sample rate is really a subjective value. The rate you choose really depends on what medium you are recording for. The top audio interfaces will allow sample rates of up to 192 kHz, but this is above and beyond what you need for recording good audio. These days 24 bit, 96kHz recordings are considered to be high resolution.

  • Phantom Power

Condenser microphones require an external power supply called phantom power. This is a 48V DC supply that some audio interfaces will have. If you use condenser mics then make sure your audio interface is equipped to power it.

  • Latency

Latency is the delay between the audio signal entering the system and then you hearing it. It is usually caused by the buffer and analogue to digital converters. A good audio interface will have minimal latency. This shouldn’t be an issue with the more well known brands.

Some interfaces will offer direct monitoring or zero latency monitoring. This is a button that allows you to hear the audio source directly, with no latency delay.

  • Balanced or Unbalanced Inputs/Outputs

XLR and TRS connections are balanced and are less prone to any signal interference, while TS are unbalanced and can cause interference called ground loop. Cheaper audio interfaces might use unbalanced connections.

  • Mic Preamps

The mic preamp takes the quiet signal that is picked up by a microphone and boosts it to a useable level that is suitable for recording. The quality of the preamps can make a big difference to the sound of your vocals. Also, the number of preamps dictates how many mics you can record.

  • Number of Inputs

A huge consideration has to be the number of inputs. Just how many instruments do you expect to be recording? Also, take into consideration what type of inputs there are. As seen in the diagram in the previous section, two mono inputs equal just one stereo input. A singer/songwriter would need just two inputs and a stereo output, while a band might want something more, especially if recording drums. A DJ would probably want at least two stereo outputs.

  • Connection Type

How will you connect it to your computer? There are 3 main choices: USB, Thunderbolt, and Firewire. Thunderbolt 3 promises huge data transfer speeds, but it is still a year or so away. USB is reliable and widely accepted across computer manufacturers. Firewire gives more consistent data transfer rates, but is not as widely accepted.

  • MIDI

MIDI isn’t as important a consideration as it once was because most MIDI devices offer a USB connection to computers now. But, if you have a few MIDI instruments then a MIDI connection on your interface might be something worth considering.

audient-1d142. Audient iD14

The iD14 is the most expensive audio interface on our list of the best. However, it does offer some extra features that might make it a worthwhile investment. The biggest difference at first glance is the ScrollControl wheel. By pressing a button, this volume control changes into a scroll wheel that can control DAWs, plug-ins, iD14’s mixer app, and even iTunes libraries. By simply hovering over an object with your mouse, it can then be controlled with the iD14 wheel. This extra interface makes life easier, and really speeds up processes that can be very time consuming.audient-id14-specs

It comes with some well designed software that means the hardware and software work together like a dream. Everything you need is available on screen, and you can route channels really easily. Plus, with the scroll wheel you can adjust things in milliseconds.

The iD14 offers two analog inputs (each with mic preamps), and also a harmonically rich JFET D.I. input. This was designed to sound like a classic valve amplifier, and means you can plug in a bass, guitar, keyboard, or drum machine directly in and start to record.

A cool feature of this interface is the option to expand it and increase the amount of inputs. There is an optical input that supports S/PDIF and ADAT. This means you can expand your interface to up to 10 inputs with an 8-channel mic preamp (like the ASP800). This makes tracking drums a possibility.

Audient prides itself on the quality of the preamps. It uses the same mic pre with all of its models, and it has a really smooth and versatile tone. It has actually been refined over 18 years with the help of industry experts. It has low noise and distortion, and plenty of room for gain.

audient-id14-top-viewThe iD14 also comes with Burr Brown converters. They are leaders in analog to digital and digital to analog conversion technology. This gives you sound quality of the highest level, and also a really low latency performance.

Key Features:

  • For Mac and Windows
  • USB 2.0 powered
  • 3 inputs/ 2 outputs
  • 96 kHz/ 24 Bit
  • 2 mic preamps

presonus-audiobox5. PreSonus AudioBox

Being a PreSonus audio interface gives this model a big advantage over most, and that is the inclusion of the PreSonus Artist DAW software. This software costs $100 on its own so that is a huge incentive alone to go with this interface. Luckily, both the software and the interface are really good, and importantly, work very well together.presonus-audiobox-back-and-front-view

The AudioBox is sturdily built and isn’t as flaky as some other interfaces. PreSonus actually claim to have driven a truck over it in testing, so you can be assured of it being strong enough to withstand being knocked around. It has the standard 2 inputs and 2 outputs. They both have mic preamps and give 48V phantom power for condenser microphones. It has a convenient mix knob that allows you to control the balance between input signals and the computer playback. This means you can have zero latency monitoring when needed.

It also has MIDI in/out connections for those who need MIDI connectivity on their interface.

As mentioned before, the standout feature of this is the inclusion of the PreSonus Artist software. Most interface manufacturers give you just the basic versions of DAWs. But Artist is actually a professional standard piece of software that we reviewed really well. It really is an amazing deal to get them both for this price. Other brands will surely have to take note.

Key Features:

  • For Mac and Windows
  • USB 2.0 powered
  • 2 inputs/ 2 outputs (+MIDI in/out)
  • 48 kHz/ 24 Bit
  • 2 mic preamps
  • Phantom power
  • PreSonus Artist DAW included (worth $100)
  • Durable casing

Bottom Line: The fact that this comes bundled with PreSonus Artist for under $100 is just amazing. It’s not the best interface we have reviewed (minor complaints of preamps running hot), but it’s still a very good one. If you’re in the market for some DAW software too, then this bundle represents impressive value.

mackie-onyx-blackjack6. Mackie Onyx Blackjack

The Mackie Onyx Blackjack boasts a more user friendly design than most interfaces. Unlike others, it uses the space on the top of the box to angle the controls towards the user. Audio interfaces are long overdue a design overhaul, and like the Audient iD14 this model offers a little extra. That being said, it isn’t going to fit very well in a rack. mackie-onyx-blackjack-top-view

The Onyx Blackjack is built to last. It is very well put together and has a sturdy construction. It’s ideal for recording artists on the move. It’s a 2 output plus two input interface with combination jacks for XLR, TRS, and TS connections. It includes phantom power, built in DIs, and analog hardware monitoring for zero latency tracking. It also comes with Mackie’s Tracktion Music Production Software. This means you can get started right away, and don’t have to splash out on an expensive DAW.

The Onyx comes with high end DA/DA converters. These give you among the most headroom and lowest distortion seen in interfaces in this price range. The preamps are also of the highest quality and are actually identical to the ones found on the most expensive Mackie studio mixing consoles. They offer plenty of gain and a rich tone.

Key Features:

  • For Mac and Windows
  • USB 2.0 powered
  • 2 inputs/ 2 outputs
  • 48 kHz/ 24 Bit
  • 2 mic preamps
  • Phantom power
  • Mackie Tracktion Music Production Software included
  • Well designed interface
  • Sturdy and durable construction

Bottom Line: The Mackie Onyx Blackjack falls into the cheapest of our price categories, but still has plenty to offer. The ergonomic design makes it much easier to use than most. It is really well put together too, and won’t be damaged easily. The combination of these things make it perfect for those who are going to be recording in lots of different places.
