If you’re recording podcasts, streaming, or doing any kind of music production on either a Mac or PC; an audio-interface will be an essential part of your home or studio set up. But with so many audio interfaces saturating the market, how do you know which one is best for you? At the end of the day, it’s all a matter of preference, with a few important factors to take into consideration. Including what your intended use is, required inputs and outputs, budget, and DAW/Software of choice.
What is an Audio Interface
Audio Interfaces are widely regarded as the brains of your studio. Connecting to your PC, Mac, or even an iOS device and providing you with high-quality sound recordings and playback. Not to mention giving you a variety of inputs and outputs that aren’t otherwise typically found on your computers internal sound card. Therefore, allowing you to connect your professional microphones, instruments, studio monitors, and other signals to your computer. Increasing both the sound quality of your computer as well as the signals that are being recorded.
To put it simply, an audio interface gets audio into and out of your PC or MAC. Turning your analog audio signals into digital information and vice versa using AD/DA converters. The higher quality your converters, the better your interface will perform. Thus, impacting the price.
Another consideration that will have an impact on price is the number of connections. Generally speaking, your audio interface will feature both microphone and line inputs. Microphone inputs typically accept 3-Pin XLR cables, while a line input will mostly accept Jack or RCA. Typically used for instruments such as synthesizers, drum machines, and DJ Mixers.
Choosing an Audio Interface: Buying Advice
Inputs & Outputs
One of, if not the biggest factors you’ll face when choosing an audio interface is the number of inputs and outputs (often referred to as I/O). Directly correlating with the price, cheaper audio interfaces generally feature fewer inputs and outputs. That being said, if you’re a bedroom producer who only needs connections for your speakers and up to a couple of microphones and instruments; then a small, desktop 2-in 2-out audio interface is sure to do the job.
Its also important to note, if you’re using a condenser microphone that requires Phantom Power. You’ll want to make sure that the audio interface you choose has Phantom Power onboard. Thankfully, most already do, so this is unlikely to be an issue.
However, if you’re in or going to be recording a larger band with several separate microphones; you’re going to need an interface with a lot more I/O. Likewise, if you’re going to be DJing with your computer, you’ll want to choose one with at least four line-level outputs. Two outputs used to send your stereo mix to the house system, while the other two outputs are used to privately cue songs. Even some electronic drum kits require separate channels for each instrument. So you might even need up to 8 separate inputs if that’s the case.
All things considered, this Top 10 list is aimed more towards the bedroom and small studio producers. Those who won’t be looking for a tonne of I/O, but still want to achieve top-notch sound quality.
Types of I/O
When you’re counting the input and output channels on an interface, it’s important to look at exactly what type of inputs they’re offering. As manufacturers could potentially be referring to any number of input types. To clear things up, most of the time they’ll be referring to any combination of the following inputs.
When it comes to connectivity, the right choice for you again depends on your specific needs. USB Audio Interfaces remain the most popular, although they don’t sport the fastest connection. That being said, unless you’re going to be recording several instruments and microphones simultaneously; then a USB connection is going to perform just fine. So if you’re on a budget, I’d definitely recommend picking up one with a USB connection!
However, if you are looking for something that’s going to give you even faster performance and zero latency; then a Thunderbolt interface will be able to give you significantly better results. Although keep in mind, it will end up costing you considerably more than your standard USB Audio Interface. Whichever connection you choose, remember to ensure your computer is fitted with the required connection.
The Connectivity Breakdown
- USB – USB Audio Interfaces are the most common, connecting directly into your USB 2.0 or USB 3.0 socket. As well as compatible with almost all computers.
- Thunderbolt – Thunderbolt Audio Interfaces are the next most popular. Most favourable due to significantly faster speeds and performance. Ideal for Mac users.
- Firewire – Firewire is an older Mac connection that was a faster option. Less compatible these days and not as quick as Thunderbolt.
- PCIe – These connections are usually found on internal and rack-mountable interfaces. Fast, powerful, and reliable, although it comes at a cost!
Another consideration, and probably the main one on your mind, is budget. If you’re just getting started as a producer, it just doesn’t make logical sense to blow upwards of $1000 on something as insignificant in your learning process as an audio interface. However, if you’re a bit more advanced, you might be considering spending the few extra dollars (or hundreds of dollars); and getting something that delivers audio quality that rivals the best of the best.
Finally, when choosing your Audio Interface, you’re going to have to make sure that it’s compatible with your DAW or music production software of choice. Although most audio interfaces these days are guaranteed to work with almost all DAW’s on the market, it’s definitely something worth double-checking! This type of problem is more typical with higher-level interfaces. Where the hardware is specifically designed around a particular recording software.
Furthermore, if you haven’t yet settled on a DAW, but you’ve seen one that takes your liking. It might be worth your money opting for an interface that comes complete with at least a basic version of that particular DAW. Therefore, saving you money. All while giving you a first-hand experience of the DAW so you can decide if it’s worth your money upgrading to the premium version.
Above all, the main things that will determine your purchase decision will be its connection, and the number of I/O. But it’s also important to factor in the little extra things as well.
- Size: How big is the unit? Are you limited to desk space, or need it for on-the-go recording? Then you’re probably not going to want to carry around a big and heavy interface!
- MIDI: Does it double as a MIDI interface so you can control your MIDI hardware? Do you need it to?
- DSP: Can you use it to save CPU on your computer
- Looks: Does it look nice? Will it complement your studio or desk setup?
- Software: Does it come with plugins, samples or DAW software that you’ll actively use.

Whether you’re planning on recording a podcast, live streaming, teaching/working from home, or getting started with music production; you don’t necessarily have to spend hundreds of dollars to get good quality sound! That’s especially the case with the Behringer UM2 and it’s no wonder it’s our best selling interface.
