Today I will talk about audio interfaces.

It can be a tricky job to choose the right audio interface for your recording home studio.

Audio interfaces have a lot of features, and there are especially a few of them you should focus on that I will talk about more here, to help you make the best decision for you and your needs.

I will start off by talking about a few things you will need to know about to be able to make a decision about which interface works for you.

​I will then move on to list the best interfaces right now, with descriptions and where to find it.

​Okay, lets get going. Here's a quick navigation to start out with, before we move on.

​Audio interface: What to think about

Here are four important factors you need to think about before buying your new audio interface. Whether you want an audio interface for mac or are looking for the best audio interface USB, keep reading. There are a lot to think about before you buy your new audio interface to make sure it works for your needs and with your computer, so hang on. 

1. Audio interface connectors

There are four options of cables that are commonly used when connecting an audio interface to computers. These are USB, Firewire, Thunderbolt and PCIE.

USB: USB 2.0 is the most common connection type people use. This is due both to its price and almost universal compatibility on both Windows PCs to Macs.

Firewire: Firewire connectors transfer data at a more consistent rate than the USB. This means that it is a more reliable choice when recording more channels at once. Firewire are mostly found on Macs. Therefore it isn´t going to be possible for everybody to use like the USB ones are. Do you own a PC? You may still be able to use FireWire, if your computer supports the installation of a FireWire Card.

Thunderbolt: Thunderbolts are faster than both Firewire and USB and has lately gotten wider popularity with newer semi-pro interfaces. Its already well established on macs and are getting more into the Windows PC market.

PCIE: These ones offer additional processing power and very high fast data-transfer. Thanks to this it has long been the standard for the professional audio interface and recording studio. They have lost their popularity in recent years because of many users wanting the ability of being able to take their recording audio interface out on the road and work from many different places and countries.

Ultimately, whichever of these choices you go to are up to you, but I recommend going for a USB one if you´re on a budget. They may be the slowest out of the bunch, but they are still more than enough for most recording home studios. Always look up the compatibility of your computer to make sure you have the right connection, too, to avoid any disappointments once your package arrives.

2. Input/Output count

To be able to calculate how many input/outputs you need, ask yourself the question ‘how many instruments/voices will I record at the same time?’. On the most basic audio interface you will usually find 1-2 I/O, while a professional one may have over 20. As an example, if you´re a solo musician you may do fine with 2-4 I/O, while a smaller songwriting team probably need at least 6-7 of them. Some who record bands need over 20 I/O, so it really comes down to what YOUR needs are and what YOU plan to do.

2.1 Types of Input Channels

Please be aware that hardware companies label their products as having X amounts of inputs and Y amount of outputs. This, however, does NOT mean that you can use all the inputs/outputs to record at once. The companies don’t specify further, so when it says something along the lines of

- (Product name) 16*8 inputs/outputs

they may include for example:

- Headphone outputs

- Line inputs (that override microphone inputs)

- Hi-Z inputs (that override microphone inputs)

What you have to look for is the ‘simultaneous audio’ to find out how many inputs your audio interface can record at the same time.

So, watch out so you don´t buy an audio interface with 16+ input channels, when only 2-8 are mic-inputs. The rest of the inputs are usually either line inputs or optical inputs.

- Line inputs requires the add-on of an outboard mic preamp, to be used as a mic channel.

- Optical input, which is a digital input that needs both the addition of an outboard mic preamp, AND a digital converter with an ‘optical out’ to use as a microphone channel.

3. Form Factor / Size and shape of your interface

There are two different options when it comes to the size and shape of your interface:

- Rackmounted Interfaces

- Desktop Interfaces

Rackmounted interfaces are larger in size, and you mount them by using a standard size rack unit.

Desktop interfaces are smaller ones who sit next to your computer.

I recommend starting out with a desktop interface, since they are cheaper, easier to use and you don´t need any special mounting.

The rackmounted interfaces usually have more input channels, so this may be the choice that more advanced studios goes for.

4. DAW compatibility

Usually not an issue, since most of the top selling DAW’s are compatible with any interface you want to buy, it´s still good to check it out beforehand. The DAW compatibility can be hard to find on the box of your audio interface, so a hot tip is to check out the products website. Like I said, this is usually not an issue but it would suck if you end up getting one that isn´t working for you.

I recommend going for an USB audio interface if you’re building your home recording studio on a budget, as this will get the job done well for the bucks. There are a few models to choose from, but the ones I recommend are….
