The 10 Best Audio Interfaces – Essential Buyers Guide 2017

Audio interfaces are the middlemen of the pc recording world, designed to take a seat between your devices and your pc, taking the sounds made by your microphones, guitars and different devices and changing them into digital info your pc can perceive and retailer on its onerous drive.

And when enjoying again your audio, it’s the interface’s job to reconvert the digital audio information again into analogue alerts that may be relayed to your studio monitor audio system or headphones. Put merely, if you wish to report any sort of excessive-high quality audio into your pc, a great audio interface can be prime of your purchasing listing (after the pc in fact!).

Once they first started to appear on the scene in tandem with the earliest arduous disk-based mostly audio recorders, audio interfaces was actually massive, costly issues, solely accessible to professional studios, costing about the identical as your common household automotive and sometimes requiring additional hardware playing cards slotted into your pc to run – the rationale why they’re nonetheless recognized in some circles at the moment as ‘soundcards’.

Your audio interface acts as the guts of your studio, connecting your controllers and enter units to the pc and again out to the audio system.

As computer systems acquired extra highly effective, with quicker processors extra able to dealing with the calls for of the duty at hand, the necessity for costly additional hardware diminished and reasonably priced, moveable USB-based mostly interfaces started to appear, permitting a fast and straightforward answer for undertaking studios and residential recordists to hook up microphones and devices similar to guitars, basses and hardware synths to their computer systems.

On the similar time, on the different finish of the spectrum, the advances in know-how which have introduced high quality audio recording into the palms of bed room producers worldwide have allowed professional studios to entry ever extra highly effective and complicated recording options.

Key Audio Interface Options To Think about

Should you’re out there for an interface, there are a number of key issues to take note of, relying in your recording necessities. At first will almost definitely be what number of inputs and outputs you’re more likely to want.

  • Variety of inputs
  • Variety of outputs
  • Portability
  • Phantom energy
  • Latency
  • Preamps
  • Converters
  • Bit depth and pattern price

Variety of Inputs

The variety of bodily inputs your interface has will decide what number of devices you’ll have the ability to document directly.

Professional studios are likely to favour a number of-enter units able to accommodating sufficient microphones for a full band to report concurrently, together with drum package, bass amp, guitar amps and vocals, together with line inputs for keyboards and suchlike. These typically function upwards of sixteen or twenty-4 bodily inputs, in addition to digital inputs that may deal with a number of channels of digital audio.

Ins and outs on the Apogee Quartet

In the meantime, house and undertaking studios are sometimes capable of get by with only one or two bodily inputs, both XLR-sort microphone inputs or line-degree quarter-inch jack sockets, so a solo artist can use them to document one microphone or instrument at a time.

Many models use area-saving, ‘combo’ inputs that may join both an XLR or a jack plug to the identical socket. So when selecting an interface, it’s essential to remember the primary situations you’ll be utilizing it in, and thus the minimal variety of microphone and/or line degree inputs you’re more likely to want.

Variety of Outputs

The variety of outputs your interface must have actually will depend on the place will probably be used and what you’ll be hooking it as much as.

Acquired an enormous mixing console with a number of channels? You’ll most probably profit from an interface with a number of outputs to feed into these channels.

Making tunes in your house studio with only a laptop computer and no outboard gear? You’ll in all probability be advantageous with a easy stereo output to hook as much as a pair of stereo monitor audio system and an honest headphone output for monitoring efficiency when recording utilizing microphones.

Almost all interfaces will come outfitted with connections for a pair of monitor audio system and no less than one headphone output, along with a devoted quantity management.


Presonus AudioBox iOne portabilityThere’s not any actual want for the typical pc musician to gather collectively an enormous rack of mains-powered, rack-mounted interfaces. A number of the smaller interfaces aimed toward undertaking studios conveniently take their energy from the USB cable that connects them to the pc, making them preferrred to be used with a laptop computer in a transportable recording setting.

So you may work someday in your house studio, as an example, then subsequent day simply chuck the interface into your laptop computer bag and take your whole setup out on the street – without having for an exterior energy provide.

Phantom Energy

In the event you’re going to be doing any critical vocal or acoustic instrument recording, you’re going to wish a condenser microphone, ideally of the massive diaphragm sort.

These tremendous-delicate mics are able to choosing up unimaginable element, however the overwhelming majority have to be powered by a 48V ‘phantom’ energy provide that powers the mic by way of the identical cable used to transmit the audio sign.

So look out for an interface with this function, and also you’ll be capable of seize intricate performances utilizing this kind of microphone.


The drawback of latency has been the one factor that interface producers have been struggling to beat since they first appeared.

The time taken for the analogue enter audio sign to be translated into digital info and again once more (generally known as ‘round trip’ latency) might solely be a number of milliseconds, however even this may be sufficient to be considerably off-placing to a performer, because it causes a perceivable delay between what they’re singing or enjoying and what they’re listening to of their headphones.

Today, because of quicker onboard processors and speedy connection protocols reminiscent of Thunderbolt and USB three.zero, the issue of latency has largely been minimised to the purpose the place it’s barely noticeable.

However, though more and more commonplace these days,  good latency efficiency nonetheless ranks as an essential function when contemplating which interface to go for.


Universal Audio Apollo Twin MkII on deskWhen recording analogue alerts from, say, a microphone or electrical guitar onto any type of medium, an honest preamplifier (or ‘preamp’) can be required to spice up the extent as much as the purpose the place it may be recorded virtually with an honest sign/noise ratio – in different phrases, in order that the specified sign is loud sufficient in comparison with the quantity of undesirable noise current within the system.

Some preamps sound so much higher than others because of the standard of their circuit design, so make certain the preamps in your chosen interface cross muster.

Once more, you definitely get what you pay for relating to preamp high quality, however there are some remarkably good-worth examples on the market, with revered corporations like Focusrite and Audient constructing only one or two excessive-high quality preamps into their models to make them extra reasonably priced.


One other very important but typically-ignored element of your audio interface is the analogue-to-digital converter (ADC) and digital-to-analogue converter (DAC). These are the elements that do the heavy lifting in terms of translating analogue audio alerts into digital info for storing in your pc, and reconverting it again into analogue once more whenever you play it again.

A common rule of thumb is that the costlier the converters in your interface, the higher your audio will sound. Like preamps, it’s very a lot a query of ‘you get what you pay for’ in terms of converter high quality, however that doesn’t imply that you would be able to’t get a extra-than-respectable outcome from a number of the entry-degree models available on the market right now.

Bit depth & pattern price

The means audio interfaces work is by digitally ‘sampling’ and changing analogue audio alerts at very excessive frequencies, slicing the waveforms up into hundreds of chunks per second. The variety of slices per second the converters in your interface function at is measured in kiloHertz (1kHz = 1000 slices per second) and is called the pattern fee. Every pattern is saved digitally in your pc’s onerous drive at a selected decision – the upper the decision, the higher the variety of bits used to characterize every pattern, a determine generally known as the bit depth.

The normal ‘CD-quality’ pattern fee and bit depth are 44.1kHz and 16-bit. Most semi-professional interfaces presently obtainable function at a minimal pattern fee of 48kHz and a bit depth of 24-bit, whereas the pattern charges of professional units can go as much as as excessive as 192kHz. Whereas this makes for distinctive audio high quality, the upper the pattern fee, the bigger the dimensions of the ensuing audio information, which means they occupy rather more exhausting disk area in your pc.
