Best Audio Interface

Do you need to record into your computer?

But you don't know exactly what you need to get the job done...

Here's what I advise:

Don't buy what you don't need!!

You want the best audio interface for your project studio...period!!!

Although an high-end audio interface boast impressive capabilities,

it doesn't mean that your sound will be equally impressive.

I'm just going to be writing about the best ten of them.

Any of these audio units have their own charm, and all of them are of high quality sound and analogue circuitry.


What is an audio interface?

First of all...

What's the difference between a sound card and an audio interface?

Well, a sound card is only used on onboard computer chips and internal cards can be connected for example to a PCI-slot.

When talking about external sound cards it's usually referring to audio interfaces.

Besides your computer and DAW the audio interface functions at the heart of your home recording studio.

It's primary function is to translate analog signals to digital signals.

Thus the quality of your recording is heavily depended upon the quality of the chips within the interface.


Types of Connections

It comes down to what you are going to use it for.

To record a signal, you need an input.

And if you want to record a microphone, you will need an input with a preamp.

To record instruments, you will need a dedicated instrument input.


You can choose an audio interface with only line signal inputs (line-in and line-out) but then you will have to invest in an external preamp and/or a direct input box.

If your working with MIDI you would probably want to have MIDI-I/O.

Most of the interfaces today offer these already.

It's good to know that most MIDI-controllers can be connected through USB.

When you have determined how much inputs and outputs you need it's time to look at another factor, mainly the converters.

The converters manage the quality of the recordings.

Converters are electronic components that are responsible of converting analog audio to digital signals (AD-DA circuits).

There are 3 ways a computer can be connected to an audio interface:

  1. Internal sound card trough PCI(e)
  2. A Firewire Interface (external) and a...
  3. USB interface (external)


Price, Quality and Quantity

"Should It Be Cheap Or Should It Be Expensive?"

High-end interfaces often have more ins and outs then low-budget interfaces.

Usually these high end products also have better microphone preamps and dedicated internal routing capabilities.

When you're a mobile recorder/producer you will probably won't have the need for all those inputs and outputs.

That doesn't mean that there isn't a high-end product that specifies your needs.

These specifications are the ones to look at when you're deciding to buy your audio interface:

  • analog I/O
  • digital I/O (ADAT 8: Channel digital audio & S/PDIF: Digital Stereo )
  • instrument inputs with High-Z
  • microphone inputs with phantom power (48+ volt)
  • MIDI I/O
  • USB, firewire, thunderbolt connections
  • headphone monitor outputs
  • wordclock I/O
  • Windows or Mac (depending on the unit)
  • Compatibility with your DAW (again, this is very important)

Let's have a breakdown of what you're missing out when you buy a cheap one:

  • a great interface build (possibly loose inputs, knobs. Plastic chassis, poor ergonomic design, portability)
  • no independent DSP (for VSTi use. Essential for bedroom producers) which would kill your CPU if it's weak as soon as possible.
  • More clutter at home (expensive AI's are huge and occupy more space)
  • Expandability (limited channels)

But if you're buying something expensive, you also miss out on:

  • Paying less (for what you really need especially if you couldn't maximize your equipment)
  • portability (some large rack interfaces are not for the frequently-traveling audio engineer)
  • low maintenance (you've got tubes to take care of. Clean your interface regularly.)
  • Poor quality sound (you will always record at 24bit rates and you'll feel your CPU run hot, but you get a decent sound!)


DAW Compatibility

Now you’ve got a great audio interface.

You immediately bought that little Focusrite interface and you couldn’t stop shaking.

Then you load your DAW and everything seems to load fine.

But you couldn’t find the right driver to make your interface work for you.

That’s a big problem. But that can be fixed with a little research.

However, the point is, if your DAW does not agree with your audio interface, you could see that your audio interface is a huge waste of money.

Always make sure that your DAW can work with your Audio Interface.

I repeat, make sure that it’s as compatible as food to your mouth when you buy that audio interface.

Especially if you’re buying expensive equipment because you don’t want to regret making a poor investment and having a difficult time reselling incompatible equipment.


Interface Connectors

Apple has Thunderbolt, a 30-pin connector that is the equivalent of USB.

Meanwhile, Windows will always have USB.

Apple said it is limited to the 5-pin that micro USBs (the same size as Thunderbolt) have and find larger USB plugs to be quite bulky for its taste.

Thunderbolt was specifically designed to carry “audio and transmit and receive”, meaning it intends to cut all latency introduced by the universal Serial Bus plugs because they have to go through so much information before they can process it.

The ability of audio interfaces to use DSP technology as well as sync VSTi recordings through a line-in instrument effectively is due to TB, which is why plenty of AI manufacturers try to go for a Macintosh approach to things.

TB allows transmission of video signals, not just charge and synchronize, which the USB 2.0 is capable of.

While Windows DAW’s have delay compensation and latency modes.

But these aren’t enough to resolve the bigger issue at hand.


Outputs Explained

Cheaper audio interfaces may only have four inputs and about two outputs, which usually go straight to your monitors.

Meanwhile, expensive audio interfaces can have multiple input/output for simultaneous recording.

Expensive interfaces, usually found in bigger studios where a single-shot recording is often likely, will have more features.

It would often have its own DSP for audio processing even before the audio reaches the DAW.

These input/output may be limited in number because they may have their own tube preamps, which are not cheap to manufacture.

Hi-Z stands for high impedance and refers to a max signal of 500 ohms.

Which is good for electric guitars and bass guitars.

Phantom Power is used for regular XLR cables which delivers 48+volt to for example a condenser microphone.

Some interfaces offer phantom power that can be switched on and off different input channels.

Your choice of audio interfaces will depend on what you need to record, which simultaneous recordings you need so that you know how many input/output you will need.


What about the Form Factor

I won’t be a hypocrite.

The size of the audio interface I need depends on what need I have for it.

For example, a Focusrite Scarlett 2i2 is useful for me when I’m traveling with my laptop.

I’d say people who love traveling and are creating pod casts would benefit from using a Focusrite interface rather than going with an eight-channel DSP rich interface.

Form factor is important for me as it will indicate portability.

The heavier the device is for me, the more I dislike it if I’m going out.

In my home recording studio, however, the heavier the better.

Part of the form factor for audio interfaces include the connectors and where they are located.

For example, I’d hate it when the master volume settings are located behind the unit when all inputs and outputs are out front for smaller units.


What Professional Interfaces Have To Offer

You’ve probably come across famous videos of audio interfaces claiming that they’re the best. Immediately, we ogle towards the screen.

Well, I remember myself doing that when I saw trials on the i-net of some artists using the Avid Fast Track One.

It was simply amazing, the way they make it look easy to operate an interface.

Well, not that it’s difficult, but it’s not all the time that the latency will work for you, or the audio is thoroughly ‘clean’ with its signal or that your guitar won’t have noise when you run it through an amp VST.

You’ll be facing these troubles. But first.


There’s No Best Audio Interface

“You wanted to see the professional way of audio production and what professional audio interfaces could do for you”

Contrary to popular opinion, there’s no single “best” audio interface, not even for professional-level audio interfaces.

There are only ones that fail their purpose either by having some jitters or they have workflow troubles.

People often rate down certain audio interfaces in the market because they did not spend enough time to learn about its architecture.

If one spent much time reading the manual and experimenting, they would do a fine job with almost any audio interface.

For example, you might have been using FireWire, but maybe your interface works better with less and thus low latency when connected through a USB while you have delay compensation turned on.

Small tweaks like these guarantee there’s no best audio interface.

You’ll find glitches here and there, but you’ll find your own solution anyway.


Jitters And Little Noise Problems

Jitters and noise problems are probably the first things you’d notice with poorly-made audio interfaces, or at least ones that are cheaper, have very poor clocking.

This is when it syncs with your CPU. The more jitters, the more latency problems.

Sometimes, it causes pitch problems.

Even professional audio interfaces suffer from these troubles.

You could lose some small details in a reverb when you have heavy jitters.

Of course, these can be difficult to hear through a normal room setting where there is lots of bounce going on.

Noise is easier to detect. Equipment noise is likely caused by poor circuitry.

It might be a defect. Make sure that when you run either low budget or an high end interface with 60 channels, you look for that noise floor. Or else you make a bad investment.

Yes, even the professional interface can fall victim to this little problem.

All rear panel connections are displayed on the top of the interface, so you don't have to search for them.

With the UR-RT2 you only get two mic inputs and one headphone connection.

But the real magic of these interfaces are the Rupert-Neve transformers.

As soon as you press the transformer switches, they provide a natural saturation and harmonic enrichment (don't activate them if you want a clean recording).

  • Includes Cubase AI & Cubasis LE for I-pad
  • 4 Rupert Neve design transformers
  • 4 analog xlr combo-inputs: 2 mic/line & 2 mic/hi-Z
