6 Best Audio Interfaces For Mac In 2020

An audio interface is one of the essential pieces of audio equipment for every recording studio (home or professional). The interface is absolutely necessary if you’re trying to record your voice through a professional microphone or if you want to record any other external source (guitar, bass, synth, etc.).

Our article about 6 best audio interfaces for Mac in 2020 is here to introduce you to the confusing world of audio interfaces. We will discuss the purpose of an audio interface, talk about different types of interfaces, give you a few tips on what to pay attention to when looking for an audio interface, and answer some of the most common questions about interfaces. Finally, if you’re looking for a new or for your first interface, we have prepared a nice selection of audio interfaces for Mac. So, let’s dive into the matter and see why are these devices so important.


What Is An Audio Interface?

An audio interface is a simple piece of audio hardware that serves as a bridge between your external audio sources (microphones, instruments) and your computer. The first purpose of an audio interface is to provide you with a sufficient number of connections for all the equipment. The second purpose of an interface is to convert all the analog audio signals received from various sources into digital signals so that you can manipulate and record those signals with a DAW (Digital Audio Workstation) software installed on your computer. Furthermore, an audio interface is responsible for digital-to-analog conversion of the signal coming from your computer, which allows you to monitor your recordings (through headphones and/or studio monitors).

Most of today’s interfaces connect to your computer via USB and are compatible with both PCs and Macs. Some use Thunderbolt 3 connection and are designed for the latest Mac computers, but can work with PCs with a USB-C connection. Some older interfaces also use Firewire connection but they are not as common anymore. All the interfaces included in our selection of 6 best audio interfaces for Mac in 2020 have either USB or Thunderbolt 3 connection.

Is Audio Interface Absolutely Necessary?

Well, we can think of certain scenarios when there’s no need for an external audio interface and when everything gets handled by your computer’s sound card. For example, if you’re just using software instruments and a 3.5mm or a USB microphone, then an audio interface is not absolutely necessary.  

However, if you want to use professional microphones that usually have XLR connections or if you want to record some external sources/instruments with ¼-in line-level outputs, an audio interface is a must. A dedicated audio interface also has a built-in mic preamp that boosts the signal coming from a microphone and turns it into a line-level signal, necessary for recording.

We did our best to make our selection as comprehensive as possible, thus allowing you to find the perfect interface for your needs. The list includes both budget and professional interfaces, more or less versatile ones, etc. One thing they all have in common is that they are perfectly compatible with your Mac.

6 Best Audio Interfaces for Mac in 2020


1. Best Overall – Universal Audio Apollo Twin X QUAD

Universal Audio Apollo Twin X QUAD

Check Price on Amazon

Check Price on Walmart

UA Apollo Twin X QUAD is our top suggestion if you’re looking for a highly capable, professional audio interface for Mac. It’s a fantastic mixture of a compact form factor, high-end audio quality, flexible input/output scheme, and great onboard digital signal processing capabilities.

Things we like

The packaging is very premium and the whole presentation is lovely. Inside the box, you will also find a power adapter, user manual, and a 1-year warranty. Twin X QUAD also comes with a very powerful Console software compatible with both Mac and iOS. Luna recording system and 14 plugins (compressors, EQs, reverbs, bass, and guitar amp emulators) are also included in the bundle. You can buy additional UAD plugins from the UA website.

Twin X QUAD has a very small footprint and looks quite attractive. More importantly, it’s control and input/output schemes are very intuitive, which makes it super-easy to use. 

On the back of the unit, you have two combo mic-pre/line-level inputs, two sets of ¼-in monitor outputs, a power supply input, a Thunderbolt 3 port, optical input (for connecting audio equipment with ADATA or S/PDIF outputs), and a power switch.

On the front panel, you have one ¼-in Hi-Z input for connecting your guitar and a ¼-in headphone output.

All the controls and LED indicators are on the top. There are only 8 buttons and one wheel, and you can use them to control all the input and monitor-related parameters. To shift between monitors/headphones and different sources connected to your Twin X QUAD, you can use the monitor and preamp buttons. Depending on the mode, you will be able to control different settings. In preamp mode, for example, you can select the input (CH1, CH2, Hi-Z), engage hi-pass, engage the phantom power (in case you’re using a condenser mic), put a pad on a mic, reverse polarity, adjust the gain (with a large wheel in the middle).

In monitor mode you can use the buttons to activate the talk-back function (use a built-in mic to talk to the artist in the recording booth), engage the dim function (lowers the volume of the monitors instantly without the need to use the wheel), engage mono mode (control your stereo image and reference your track), and mute.

As you can see, the controls are very intuitive. You just have to select the mode, then select the thing you want to control, and the available control options will light up.

Twin X QUAD has a built-in quad-core DSP chip which enables you to run the above-mentioned UAD plugins in real-time with close-to-zero latency. Realtime UAD processing is done within the included Console software and can be routed to any DAW software you’re using.

The unit has an impressive D/A dynamic range of 127dB and has the lowest noise (-117 dB THD+N) among desktop audio interfaces. It can handle 24bit/192kHz conversion and delivers organic and spacious sound, on par with top-of-the-line professional interfaces.

Thanks to its optical input, the unit can be configured for stereo S/PDIF operation or you can connect it to the gear with ADAT OUT and expand the number of available input channels to 10 (2 + 8 ADAT).

Thanks to the Thunderbolt 3 connection, you get the fastest possible processing and the lowest possible latency. Also, this connection allows you to chain up to 6 UAD-2 devices (or 4 Apollo devices).

To conclude, UA Apollo Twin X QUAD is, arguably, the most capable desktop audio interface. It’s very user-friendly, very reliable, it comes with an amazing set of plugins and recording software, and it delivers very natural and organic sound.

Things we don’t like

The Thunderbolt 3 cable is not included in the package and that’s a little bit disappointing considering the price. However, that doesn’t make this highly capable interface less amazing.

2. Best Under $100 – PreSonus AudioBox USB 96

PreSonus AudioBox USB 96

Check Price on Amazon

Check Price on Walmart

Looking for a budget-friendly interface under $100. Your best option is PreSonus AudioBox USB96. It’s a portable, USB-powered, user-friendly, and reliable audio interface, compatible with both Mac and PC.

Things we like

PreSonus AudioBox comes in a nice-looking illustrated box. You will also get a USB Type-A to Type-B cable, user manual, warranty card, and the PreSonus Studio One Artist software. This software becomes available for free download once you register your product. The software bundle also includes PreSonus’s Studio One Magic software that includes Ableton Live Lite, some virtual instruments, and 9 plugins.

The unit has a strong metal housing and it’s available in two colors – black and blue/silver. It has a simple input and control scheme. On the front side, you have two combo mic-pre/line-level inputs (accept both XLR and ¼-in connectors) and a series of knobs. You have two gain dials, one for each input, with dedicated clipping LED indicators, one headphone volume dial, monitor volume dial, and one input/playback mixer dial. The last one allows you to mix the input signal with the playback stream and monitor your input signal with minimal latency. The front panel also houses a tiny 48V phantom power button (for condenser microphones).

On the back, there’s a headphone output, one set of line-level monitor outputs, 5-pin MIDI IN/OUT ports, and a USB Type-B port for connecting your computer. PreSonus AudioBox USB 96 is one of the rare audio interfaces that allow you to connect your synth or MIDI controller. If you need a MIDI-enabled device and you have a very limited budget, this is the unit for you.

Both combo inputs have built-in Class-A mic preamps and provide you with a pretty great low-noise performance. The max supported conversion rate is 24bit/96kHz. So, it’s definitely not as high-quality as previously reviewed Apollo Twin X QUAD (24bit/192kHz) but, honestly, it’s really hard to notice a difference between 96kHz sampling rate and 192kHz sampling rate, especially if you are just a beginner or if you’re a regular listener.

The software that comes with the unit is compatible with macOS X 10.11 or higher as well as Win7 x64/x86 or higher. There are also certain hardware limitations, so be sure to check them out and make sure that your Mac or PC can work with the included software.

Things we don’t like

The instrument inputs don’t have quite the same amount of headroom as some other interfaces with dedicated switches for line-level inputs (INST/MIC switches) so you should be careful when connecting synths or drum machines. You should pay close attention to the volumes so you don’t overload the inputs.

3. Best Bang for The Buck – Focusrite Scarlett 4i4

Focusrite Scarlett 4i4

Check Price on Amazon

Check Price on Walmart

Focusrite Scarlett interfaces are currently the most popular affordable audio interfaces for Mac and PC. Scarlett 4i4 is a compact and robust unit with an easy-to-navigate control panel. It offers versatile connectivity and pretty great performance. In our opinion, this unit (and Focusrite Scarlett interfaces in general) have the best price/quality ratio. They are not too expensive and they offer more than you expect.

Things we like

The unit comes with a USB cable (Type-A to Type-C), manual, and a warranty card. The unit also comes bundled with Focusrite Creative Software Pack that includes Ableton Live, a 3-month Splice subscription, the Focusrite Control app (for Windows, Mac, and iOS), and all the other software tools you need to start recording immediately.

Scarlett 4i4 has a very sleek aluminum chassis with a red finish and a simple branding on the top. The front panel houses two combo XLR/¼-in inputs for attaching mics and line-level instruments. There’s a dedicated gain knob for each channel with a circular LED indicator. 

Furthermore, below each of these two combo inputs, there are three indicators – INST, AIR, and PAD. There’re no buttons to activate these settings/modes, which means that you have to use the Focusrite Control software. You’re supposed to select the INST in the Control software when using a guitar connected via a 2-pole guitar jack and to deselect it when using a synthesizer or keyboard. When you activate the AIR mode (again – you have to do that through Control software), the frequency response of the input stage will be modified to simulate Focusrite ISA microphone preamps. When you select the PAD feature in the Control software, the level of the signal sent from the input stage to your DAW is attenuated by 10dBs.

The front panel also houses a monitor volume dial, headphone output, headphone volume dial, 48V phantom power button (for condenser microphones), and MIDI LED indicator (lights up green when there’s a device connected to MIDI IN). 

The unit has no MIC/INST (or MIC/LEVEL) switches for selecting the type of device connected to the interface. Instead, the unit has two automatic configurations. Depending on the connector type (XLR or ¼-in), the device will automatically use the configuration for a mic (XLR) or an instrument (¼-in).

On the rear panel of the Scarlett 4i4, you have two balanced line-level inputs (for drum machines, keyboards), four balanced line-level outputs (for connecting one or two sets of monitors), a set of 5-pin MIDI in/out ports (for connecting MIDI keyboards or MIDI controller), and a USB Type-C port.

Scarlett 4i4 supports 24bit/192kHz conversion. It comes with all the software necessary to start recording immediately, and delivers perfectly reliable performance. 

Things we don’t like

The unit uses a USB Type-C port but runs on a USB 2.0 protocol. It doesn’t run USB-3.0/3.1, let alone Thunderbolt 3. The performance is still great for the price.

The next device on our list of 6 best audio interfaces for Mac in 2020 is a little bit different than others. This one is made for guitars and other instruments with line-level outputs and it works best with Apple devices (Macs, iPhones, iPads). It’s super-compact and portable, it’s very easy to use, and enables 24bit/96kHz conversion. 

Things we like

iRig HD 2 comes with two cables – one Lightning-to-micro-USB and one USB-to-micro-USB. During the initial setup, you are supposed to install the AmpliTube software for Mac or PC – it’s free recording software with a bunch of pedal and amp emulators. Once you register the device, you can also install the same software on your iOS device (AmpliTube for iOS). The unit also comes with a plastic clip and Velcro strip for mounting on a mic stand.

iRig HD2 has a very tiny form factor and looks like an mp3 player. At least, at first glance. On the front side, you will see the iRig logo and an LED indicator showing the working status and signal strength (orange – good input signal, green – low input signal, red – too high input signal). On the back, there’s a clip for mic stand mounting.

On the bottom of the unit, you have one ¼-in guitar input and a ¼-in Hi-Z output (to connect an external amp or mixer). On the top, there’s a 3.5mm headphone/monitor output and a micro USB port. The input gain dial is on the left. The headphone volume dial and FX/THRU switch are located on the right side. The switch allows you to choose the kind of signal (clean or processed) you want to send to your amp.

Things we don’t like

The unit can be hooked up to Windows PCs and other Win devices but offers sub-par performance (compared to setups where Apple devices are used). When connected to Windows devices, you may experience greater latency, noise, driver issues, etc.

On the back of the unit, you have two additional line-level 6.35mm TRS inputs, 4 TRS monitor outputs, one S/PDIF stereo IN, one S/PDIF stereo OUT, MIDI IN/OUT, and a USB Type-B port for connecting your Mac/PC.

On the top, you have four VU gain meters for the inputs, one VU meter for the outputs, three LED indicators (USB, 48V, and MIDI), and a large volume knob for the monitors.

Komplete Audio 6 Mk2 supports 24bit/192kHz AD/DA conversion and has very low latency, providing you with flawless performance regardless of the size of the setup you are using.  

Things we don’t like

Locating and downloading the software takes some time and it’s a bit of a hassle. You have to use the NI’s installer app called Native Access and you have to register your interface before the download. Also, some of the software tools are just demo versions.

FAQs

Q: What is the best audio interface for Mac in 2020?

A: There can’t be only one answer to this question since we don’t all look for the same things. Some people look for a more versatile interface with numerous inputs/outputs, others just want to connect two or three mics to start a podcast. Also, some people look for a good-performing entry-level interface, while others look for top-of-the-line professional equipment. Whatever you’re looking for, we have you covered. Just go through our list of 6 best audio interfaces for Mac in 2020 and find the perfect device for your needs. 

Q: Do I need an audio interface for my Mac?

A: As discussed in the introduction, there’re some situations when you don’t have to use an audio interface (when you’re not recording instruments and when using lower-quality 3.5mm microphones or USB microphones). In all the other scenarios, using an audio interface is strongly recommended. If you want to record a guitar or a synth – you need an interface, if you want to use professional condenser or dynamic microphones – you need an interface, if you want to use external studio monitors – you need an interface.

Q: Which audio interface is best for beginners?

A: You should probably start with something cheaper and simple. Focusrite is a pretty popular entry-level choice. The Focusrite interfaces deliver pretty good sound quality and overall performance, they are very user-friendly and quite reliable. You won’t get the same level of performance you would get with professional equipment but, for the price, it’s pretty great. Some other budget-friendly brands you could check out are Yamaha, Behringer, PreSonus, Mackie, etc.

Q: Do I need an audio interface if not recording?

A: If you’re not recording, then it’s not necessary. If you’re just playing with software instruments and don’t want to record your voice, guitar, or other instruments, then you don’t have to buy it.  

Q: Do I need an audio interface if I have a mixer?

A: If you have a USB mixer, then you don’t really need a dedicated audio interface. However, the problem with most budget-friendly mixers is that, even if they have more inputs than your audio interface, they will often mix everything into just two channels and those two channels will be sent to your DAW. So, if you want to record multiple audio sources and to be able to manipulate them all separately in your DAW, an audio interface is a better option. A USB mixer is a good choice for live performances and for live podcasts, while an audio interface is better for recording.
