The Best Audio Interface

Audio interfaces are amazing inventions, they allow users to plug in microphones and instruments and record to one of the many digital audio workstation software packages available. Perhaps the idea of you recording some tracks that you’re written, or putting out some music with your band is quite scary because studios are quite expensive right?

The technology has advanced to a point where it has become incredibly easy for us to gain access to studio quality equipment that we can use in our own homes and get the same results.

If you are setting up a home studio an audio interface is an essential piece of gear. The audio interface is the brain of the operation and will convert your analog signals into digital information.

Audio interfaces are typically connected to a computer or laptop via a USB cable. You may also find some manufacturers offer a Firewire, Thunderbolt or PCI Card option. Firewire and Thunderbolt connections are not as common and PCI cards are only really recommended if you are leaving this set up all the time, for instance, in a commercial studio.

USB interfaces come in a range of sizes from 2 inputs to 24 inputs. The advantage to USB is that it is widely compatible with most computers/laptops and the smaller interfaces are very portable meaning you can take  your studio anywhere in the world with you.

Let’s look at 10 great and affordable audio interfaces that you can use to start recording today.

Focusrite Scarlett 2i2

Focusrite are one of the market leaders for USB interfaces and their Scarlett range offers incredible quality at a price that won’t break the bank. The 2i2 runs at 24bit/192kHz so is capable of full studio quality sound and it’s small enough to fit in the front pocket of a laptop bag.


Portable audio interfaces like this are small enough to fit into any bag and can be used to make music anywhere, anytime.

The unit has 2 combi ports on the front which double as XLR ports and ¼” jack ports, and it has 2 ¼” jack outputs on the rear for connecting to a set of studio monitors. It also has a headphone jack on the front for those late night mixing sessions on tour in the hotel room.

The unit is totally USB powered meaning you only need to carry it’s USB cable. It also has phantom power to power any condenser mics you might want to use, especially for tracking vocals.

The Scarlett preamps are very natural sounding with a lot of headroom and don’t colour the input signal so what you put in, comes straight back out.

48v Phantom Power is also available for powering condenser mics and the unit is totally USB powered so no external power source is needed. Couple that with a USB/Direct knob for balancing between the direct signal and the USB processed signal for zero latency monitoring when recording.

Each of the volume knows for the pair of inputs also has a 4 LED volume meter which has green, yellow and red lights so you can see when input signals are clipping.

PreSonus Studio 24c

For the home recording enthusiast who needs more connectivity, the Presonus Studio 24C should be a unit you consider. The front of the unit contains a pair of XLR/Jack combo inputs, an LED input/output meter and volume knobs for both inputs, usb/direct monitoring blend, headphone volume and master volume.

The unit also has 48v phantom power, there are a lot of features here and that is just the front panel.

This allows you to connect a range of MIDI based equipment such as MIDI keyboards and controllers to the interface.

PreSonus are so keen to help you get things started that they’ve even included a copy of PreSonus Studio One Artist, their world class DAW software. This allows you to start recording your ideas and building your sound straight out of the box.

Zoom U-24

If you are looking for a simple, no frills USB interface for recording, the U-24 from Zoom could be just what you’re looking for. This unit has a pair of top mounted XLR/Jack combo inputs, a pair of outputs for connecting monitors and a headphone out.

Allen & Heath ZEDi 10

Allen & Heath are a big name in the mixing desk work and it’s no surprise to see them launch a range of mixing desk form audio interfaces. The great news is, these are very affordable and incredibly useful for the budding music producer.

The ZEDi 10 is a 4 in/4 out interface with a huge range of features. Each of the 4 main channel strips contains both an XLR and an Instrument Jack input while the first 2 channels have a button specifically for plugging guitars straight into the desk. Activating this feature increases the impedance of the input meaning you won’t need a DI box.

All four channels have a low cut button that will automatically roll off any unwanted low end as well as a dedicated 3 band EQ, AUX send level, FX send level and pan control. You also have the option of switching specific channels on and off in the headphone mix.

At the end of the 4 main channels there is also a pair of stereo inputs which can be used in conjunction with the FX Out to send and receive signals from external effects units.

The main out is a pair of male XLR ports which indicates as well as being a fantastic studio unit, this unit could also be used for live use. The master volume being on a fader gives the unit a real studio feed and allows you to easily adjust the volume.

A pair of LED meters will show you the output volume so you can make sure nothing is clipping and the unit is also able to power those 48v hungry condenser mics with it’s inbuilt phantom power.

Behringer UMC 404HD

Another entry from Behringer in the form of a multi input interface. This 4 in/4 out interface is a get unit for anyone needing to record multiple mic sources at the same time.

The unit has 4 XLR/Instrument Jack combination ports across the front, each one with Behringers famous Midas preamps and each input has a dedicated volume knob, pad switch and a line/instrument selector for changing impedance between XLR and jack inputs.

The unit also has the zero latency option for direct monitoring and headphones, but where this unit really stands out is it’s output section. The unit has the capability to run 2 separate sets of monitor speakers which are A/B switchable via the front panel, and there are outputs that can be used in conjunction with the 4 insert points on the back to link up external preamps or effects. This means you can link up to 4 external units with your device.

There is also a MIDI in/out for linking up any MIDI controller surfaces or keyboards.

Due to this unit having so many features, and 4 mic preamps with phantom power, the unit does require a power supply to be connected so it won’t run off USB alone. This is a minor compromise when you have this 4 in/4 out interface running high quality pre amps at 24bit/192kHz.

This is a fantastic option for any studio or musician on the go.


 Some interfaces come with a range of options such as multiple pre-amps which are ideal for recording multiple sources at the same time.

To get you started, Lexicon even include a copy of Cubase LE and their own Pantheon reverb plugin, modelled on their hardware units seen in studios around the world.

How to Choose the Best Audio Interface

Buying your first audio interface can be a daunting task but just keep in mind that you can never go too far wrong. Most interfaces available across all budgets are fit for purpose. The biggest factor in choosing the right one for you is the purpose behind it.


For those who need to look into recording larger groups, some of the mixing desk style audio interfaces allow you to record multiple sources at once and also have the function of a mixing desk at the same time.

If you only need to record one or two sources at the same time, a small interface will be perfect. If you want to record a full band, you need to consider one with a range of inputs and perhaps as you get more serious about that, look at revisiting your budget.

The interfaces in this list were chosen for their ability to cover a wide range of purposes.
