If you want to know what is an audio interface, then you probably mean how can I record my …. voice, guitar, keyboard, Ukelele, or anything else that makes a sound! So you know you probably need an interface … but you need to know more!

Welcome to our complete beginners guide to audio interfaces. Here we explain all the basics so you can choose the best interface for your home recording studio.

But first, check out my video, which features the Focusrite Scarlett 2i4 USB audio interface, to get the basics.

Because an audio interface is, quite simply, what you need to get sound in and out of your computer. If you want to make a good quality recording of your voice or any instrument and hear the results so that you can mix and master your recordings, you will need an audio interface. If that has answered your question, then you can hop straight to our post that lists all the most popular audio interfaces right now in 2019.

Audiophile 48 kHz resolution for professional audio quality; Compatible with popular recording software including Avid Pro Tools., Ableton Live., Steinberg Cubase., etc. Streams 2 inputs / 2 outputs with ultra-low latency to your computer, supporting Mac OS X. and Windows XP. or higher. You can almost certainly already record and playback with your laptop, pc, mac or tablet, but buying an audio interface will take you one step towards sounding more professional. An audio interface is the equipment that sits at the heart of any home recording studio.

You can make basic recordings with any modern computer, laptop or tablet as they all come with a built in sound card. You can improve the sound of your recordings to some extent, especially on phones and tablets, with a better microphone. However to really make a professional recording you will need an audio interface or a better sound card.

Below is some detailed info about what is an audio interface, and what it is used for, then we also have a detailed post on how to choose the best audio interface for you.

I’ve got a USB Mic, do I need an interface as well?

Aha, this is such a common question and a source of much confusion! You tend to think of an audio interface as a box with various inputs for mics, instruments etc and outputs for speakers and headphones. But there are lots of other devices that are effectively “audio interfaces” too. A USB mic is a classic example.

Effectively a USB microphone is a mic that contains an audio interface. This means you simply plug the mic’s USB lead into a USB port and it will work. You don’t need any other equipment. It may just be a recording mic or it may also have a headphone output too and be a complete input and output device.

There are other USB audio adapters that fit into this category. They work on their own and don’t need any other equipment. So you can get an XLR-USB cable to connect a mic up to your computer, and also guitar-USB, line out to USB etc etc.

Essentially yes, a sound card and an audio interface do the same basic job. To get sound in and out of your laptop, pc, mac, tablet so that you can process and edit it you need something that turns the sound into a digital signal and back again. That’s what the soundcard or interface does.

You can almost certainly already record and playback with your laptop, pc, mac or tablet, but buying an audio interface will take you one step towards sounding more professional. An audio interface is the equipment that sits at the heart of any home recording studio.

So what is the purpose of an audio interface?

Ease of use and high quality recording – one of the main advantages of an audio interface over on-board sound cards is that, because of the greater physical size and easier accessibility, a wider range of input types can be built into the unit. So, for instance, ¼” jack guitar inputs can be included, as can full XLR microphone inputs, meaning that the device can be capable of connecting to wide range of professional recording equipment. In addition to this, audio interfaces generally feature higher quality audio quality than standard on-board sound cards. Many also have MIDI if you want to connect a keyboard controller too.


How do I connect an audio interface to my computer?

Most audio interfaces are USB soundcards. As long as you have an available USB port or a USB adapter in the case of a tablet then you can connect one up (you will need to check the hardware specs to make sure it will be compatible). So USB audio interfaces are the most common and you should find one that will suit you. There are also a growing number of thunderbolt audio interfaces, and you can still buy firewire too. Thunderbolt and firewire have the advantage of being faster, but tend to be pricier. And of course you must have one of those ports available. As USB has got faster, most people with home recording studios find a USB recording interface is perfect for them.

What is the best external soundcard or audio interface for music production?

We have a sister article which looks in depth at how to decide which is the best interface for you. There is no one right answer! But briefly the audio interface that you will need very much depends on what kind of recording situations you would be aiming to use it in.
  • A guitar playing, singer/ songwriter may find that a fairly straightforward audio interface with two mic inputs and two outputs (i.e. one stereo output) will be just fine, and enable recording on vocals and guitar on two separate tracks. A podcaster would look for one mic input – but if you ever plan to do interviews you might consider two so that you can each have your own mic.
  • A band would, most likely, require something with more inputs, however, especially if they want to record all the instruments on separate tracks. The other option is just to record the main outs of a mixer, but this will not allow for individual editing of each player and singer.
  • A Laptop/ Computer DJ will need an audio interface with at least two stereo (or four mono) outputs. This allows the chosen DJ software to be configured with, for example, a separate cue mix via headphones and a main mix, which is sent out to the main speakers or PA. Alternatively, each ‘virtual turntable’ could be assigned its own output, and connected to a hardware DJ mixer, for more conventional mixing.

Finally when you know how many inputs and outputs you think you will need, it is a case of choosing how you want to connect – USB, Firewire or Thunderbolt.

Technical terms that you may see when looking for an audio interface

Latency: this is where there is a noticeable delay between the actual sound, and its playback in your headphones or speakers which can be very distracting. On modern computers, latency is not a bad as it used to be, but the standard sound cards built into computers are not great, and a dedicated interface will improve this to the point that you shouldn’t even notice any latency. So, if you’ve ever recorded a vocal part, and heard your performance delayed by fractions of a second in your headphones, or used a MIDI keyboard to play a software synthesiser, but encountered a delay between pressing a key and hearing the sound, then an audio interface will fix this problem.

Zero Latency Monitoring (or Direct Monitoring): many audio interfaces have a switch to enable you to hear your sound source directly. So if you are recording your voice, you instantly hear your voice directly in the headphones, there is no annoying delay, and this is certainly a feature to look out for.

Drivers: are pieces of software that enable an audio interface to communicate with the computer. Again, they will help to reduce latency to the point where you won’t notice it.

Pre-Amps: Also known as the “mic pre”, this is the microphone preamplifier, which amplifies the generally very small signal from a microphone up to a suitable level for recording. If you want to make a good recording from a microphone you will need an interface with a suitable input and good pre-amp.

48V phantom power: Some microphones need power, either to drive active circuitry, or, more usually, to polarise the plates of a condenser microphone. If you want to connect up a microphone that requires phantom power then you will need to purchase an interface with a phantom power switch. If you just have a dynamic microphone then this will not be an issue.

MIDI: some audio interfaces also have MIDI in and out. Read our article all about MIDI to find out a bit more and decide if you need to look for an audio interface with MIDI. Most modern MIDI controllers work with USB so this is not as essential to have on an audio interface as it once was.

Sample Rate: This is how many times per second that a sound is ‘sampled’ to create the digital signal. The higher the sample rate the higher the frequency range of sounds that can be recorded and processed. The standard sample rate is 44.1 kHz, which can record sounds up to about 22 kHz. We can’t hear above about 20kHz so you’d think 44.1kHz sampling was sufficient, and often it is. However sampling at higher rates (typically 88.2/96) allows the filters required in digital audio to be well outside the human hearing range, which will improve the quality. So when you are choosing an audio interface this is one of the ways of comparing them. For more information on this rather technical subject there’s a nice article here on sample rate and bit depth.

Balanced/Unbalanced: Unbalanced outputs and inputs are made with ‘single-core plus screen’ cables whereas balanced outputs are ‘two-core plus screen’. (XLR and TRS inputs and outputs are balanced, whereas TS are unbalanced). Many budget interfaces are made to a price and have unbalanced inputs and outputs, which can lead to interference and what is called ‘ground loop’.

If you choose balanced outputs and use balanced cables then any interference picked up by the cable is picked up equally by both cores and is cancelled out at the far end, and possible ground-loop problems also disappear because the screen connection is this time not part of the signal path. For simple one or two track recording you should be aware of these differences, but you should be able to make a good quality recording on a budget interface if connected up correctly. If you want to know a bit more about this, refer to our in-depth post on audio cables explained which demystifies this topic.

Whether you’re starting a new home studio, or improving an existing one…

There’s no single purchase more confusing than the audio interface.

Because among the dozens of options…

Each one is designed to meet the demands of a specific “type” of studio.

For example

At one extreme, a small $100 interface might be perfect in a simple bedroom studio…

If all you need is a single pair of outputs for your studio monitors.

At the opposite extreme, a pro studio that requires dozens of INs/OUTs might need several interfaces, each costing $4000 or more.

Needless to say, matching the right interface with the right studio is tricky even for the experienced. And for beginners, its 10x worse.

Which is why for today’s post, I’ve created an in-depth guide to help you find the perfect option for your studio.

So let’s get started. First off…

The 5 Key Features to Look For

Because of the fact that audio interfaces have so many features, it’s difficult to know which ones matter, and which ones don’t.

So let’s talk about that now. In particular, these are the 5 key specs to focus on:

  1. DAW Compatibility
  2. Interface Connectors
  3. Input/Output (I/O) Count
  4. Input Channel Types
  5. Form Factor

And here’s why:

1. DAW Compatibility

In general, most DAW’s work with most interfaces…but not always.

If you don’t yet have a particular DAW that you are loyal to, then you need not worry here.

Because 90% of the top DAW’s will be compatible with any interface you choose.

However if you alreadyhave a DAW you want to continue using, be sure to verify compatibility on the company’s website. And just to warn you, this info is often hard to find.

You would think they would just post DAW compatibility in the interface’s product description, right? But it rarely happens. Usually it’s buried somewhere within an FAQ page.

While it’s not clear why this is done, my best guess is that these companies prefer not to advertise their current DAW compatibility, because they have no guarantees of future compatibility.

A particular interface might be compatible with your DAW today, but it may not be in a future release. And while that’s not likely to happen, it’s always possible.

Which is why personally, I prefer to use a DAW/interface combo made by the same company. Later in this post I will give you some good examples of these.

However, since there are only a few companies that make both, the downside to this solution is that it severely limits your options.

Up next…

2. Interface Connectors

When connecting an audio interface to a computer…

There are 4 cable options commonly used:

  1. USB– which is typically seen on cheaper home studio interfaces, and offers the slowest data transfer rate.
  2. Firewire– which is used on more expensive home studio interfaces, and offers a significantly faster transfer rate (nowadays these are becoming less common).
  3. Thunderbolt– which has recently become popular with newer semi-pro interfaces, and is way faster than either USB or Firewire.
  4. PCIE– which has long been the standard connection for professional interfaces, because it offers additional processing power and extremely fast data-transfer.

While USB is by far the slowest of all 4 options, it is still more than fast enough to get the job done for the vast majority of home studios.

So if you’re on a budget, USB is what I recommend.

But whichever type you choose, remember to double-check that your computer has the appropriate connection.

3. Input/Output (I/O) Count

On a typical interface, I/O counts can range anywhere between:

  • 1-2 on a simple interface, to…
  • 20+ on a professional one.

And the number you need for your studio depends mainly on the number of tracks you plan to record/monitor at once.

For example:

  • Solo musicians – may need only 2-4.
  • Songwriting teams – who work in small groups, want at least 4-8.
  • Engineers who record bands – should have as many as possible (16 at least).

Also…electronic drum kits alone can sometimes require 8 inputs if they offer separate channels for each part of the kit. So take that into consideration if you plan on using one.

4. Input Channel Types

One thing recording newbies often fail to realize is…

When counting the input channels of an audio interface, manufacturers could be referring to any number of different input types.

However in almost all cases, it includes some combination of these 3:

  1. Mic Input – which allows you to connect a mic directly to the interface.
  2. Line Input – which requires the addition of an outboard mic preamp to be used as a mic channel.
  3. Optical Input – which is a type of “digital” input that requires the addition of BOTH an outboard mic preamp, and digital converter w/ “optical out” to be used as a mic channel.

Now here’s what this means for you:

If you want to use your interface “as-is” without adding a multi-channel mic preamp, you might have less available inputs than you think.

Because as you’ll notice, interfaces often have 16 or more total input channels, but only 2-8 mic inputs.

So without any additional gear, the “real” number of inputs on your audio interface is the mic preamp count, NOT the same as the input count.

Now that you know…make sure you actually have enough channels for your purposes. Otherwise you will be sorely disappointed.

Mac

NOTE: Two other input types that you should also look for are DI inputs (if you play guitar/bass), and MIDI inputs (if you use any type of keyboards/MIDI controllers).

5. Form Factor

A fancy jargon term used by computer geeks…

Form factor” simply refers to the physical size and shape interface.

The two form factor options are:

  1. Desktop Interfaces – which are smaller, and sit on your desk next to your computer.
  2. Rackmounted Interfaces– which are larger, and mount in a standard size rack unit.

For beginners, I recommend starting with a desktop interface, because they’re cheap, easy-to-use, and require no special mounting or peripheral devices. You just plug them in and start recording.

With intermediate/advanced studios, rackmounted interfaces are typically better, as they tend to offer more I/O’s, as well as greater flexibility with signal routing and organization.

Now that you know what to look for, let’s check out some specific models.

Starting with…

Best Desktop Interfaces

For the vast majority of people reading this article, who only want a cheap interface that will allow them to record their music at home…

I recommend a 2-6 channel USB desktop interface, which normally costs between $100-$300 on the low-end, and $500-1500 on the high-end.

Currently, the top brands for these “types” of interfaces are Presonus, Focusrite, Avid, Universal Audio.

Here are the models I recommend from each brand:

Here are 2 more great budget desktop interfaces to check out:

  • Audient iD4 (USB) – (Amazon/Thomann)
  • Audient iD14 (USB) – (Amazon/Thomann)

And here is 1 more great high-end desktop option:

  • Antelope Audio Zen Tour (Thunderbolt/USB) – (Amazon/GuitarC/MusiciansF/Thomann)

Up next…

Best Rackmounted Interfaces

For the purposes of this article, let’s define an “intermediate” studio as a home setup that requires a higher I/O count to meet the demands of some of the more complex recording tasks.

If that’s the type of studio you need, I recommend an 8+ channel rackmounted interface.

Again…the best interfaces in this category are made by Presonus, Focusrite, Apogee, Universal Audio, and Antelope Audio:

Here are the top models I recommend:

Presonus

  • Audiobox 1818VSL (USB) – (Amazon/GuitarC/MusiciansF/Thomann)
  • Firestudio Project (firewire) – (Amazon/GuitarC/MusiciansF)
  • Studio 192 (USB) – (Amazon/GuitarC/MusiciansF/Thomann)

Focusrite

  • Scarlett 18i20 (USB) – (Amazon/GuitarC/MusiciansF/Thomann)
  • Clarett 8Pre (thunderbolt) – (Amazon/GuitarC/MusiciansF/Thomann)
  • Clarett 8PreX (thunderbolt) – (Amazon/GuitarC/MusiciansF/Thomann)

Apogee

  • Ensemble (thunderbolt) – (Amazon/GuitarC/MusiciansF/Thomann)

Universal Audio

  • Apollo 8 (thunderbolt) – (Amazon/GuitarC/MusiciansF/Thomann)
  • Apollo 16 (thunderbolt) – (Amazon/GuitarC/MusiciansF/Thomann)

Antelope Audio

  • Antelope Audio Zen Studio – (Amazon/GuitarC/MusiciansF/Thomann)
  • Antelope Audio Orion Studio – (Amazon/Thomann)
  • Antelope Audio Orion32+ – (Amazon/Thomann)

And finally…

“Professional” Interfaces

While any of the interfaces we’ve covered so far are more than capably of producing “professional” results…

There’s higher class of audio interfaces that we have yet to cover.

Normally only seen in high-end pro studios, these multi-thousand dollar interfaces typically connect to a separate PCIE card which can only be installed on a desktop computer.

The typical reason studios acquire this type of interface is to upgrade to Pro Tools HD, which is the standard system used by the majority of pro studios in the world.

In terms of performance, they offer many premium advantages, including:

  • Ultra-Low latency
  • High I/O counts
  • Premium Digital Conversion
  • Multiple Connection Options

And while these interfaces would almost certainly be overkill for the average home studio…

It’s still good to know about them, just in case the day comes when you decide your studio needs one.

Some examples of popular interfaces in this category are:

  • Avid HD 16×16 – (Amazon/MusicianF/Thomann)
  • Apogee Symphony – (Amazon/GuitarC/MusicianF/Thomann)

Now one last thing…

Assuming you chose a rackmounted interface, you’ll obviously need a rack to store it in, right?
