Looking to buy Audio Interfaces?

Music lovers - fear not! When it’s time to start recording, OnBuy's sellers understand that studio sound quality is of the utmost importance. Our dynamic range of audio interfaces will transfer your vocals or musical instruments directly from the microphone to your PC or device of choice without missing a beat.

If you are just starting out, a sensible audio interface to get going with is one that has at least two inputs, microphone and instrument, and two outputs. Having a bare minimum of two inputs will give you the versatility you need later down the line, even if you are only planning to begin recording with just one (it also adds little to the price!). As an audio interface can also route audio out from your computer to your stereo headphones or studio monitors, outputs for both of these are also likely to come in handy. Though basic interfaces vary in price, from as little as £50 to a whole lot more, the main difference you’ll want to watch out for between brands is the quality of the built-in analogue-to-digital and digital-to-analogue converters. As you can imagine, these two converters are crucial as they affect the audio signal quality on the way in while you’re recording and on the way out when you’re playing back your music.


What does an audio interface do?

An audio interface is a device that is used to make high-quality recordings. These nifty devices have instrument and mic inputs that typically connect to your computer via USB-C cables, though some use Thunderbolt, Firewire, or even Ethernet - so be sure to check that the audio interface you purchase is compatible with the device you plan to transfer your recordings to. Audio interfaces operate as an external sound card to convert your sound signals into a format your computer or other devices, such as a tablet, understand. Interfaces have a varied price range, from cheaper interfaces that are well under £100 to the more advanced range upwards of several thousand pounds - though, don't sweat, even the most affordable interfaces can sound fantastic and provide basic features.

Do I need an audio interface?

Audio interfaces allow you to transfer sound in and out of your computer. If you want to record your voice or any instrument and hear good-quality results to later mix and master, you will need a decent audio interface. Sure, every modern computer, laptop or tablet likely comes with a built-in sound card and microphone; however, to make a recording that really has professional and smooth-sounding audio quality, you will likely need to install a better sound card or simply purchase a good audio interface.

When choosing an interface, here are a few basic questions you should ask yourself before making your choice:

  • What connection does my device provide (for example, USB connectivity, Thunderbolt, Ethernet)?
  • Is my equipment compatible with the audio interface I plan to buy?
  • What monitoring controls will I need (for example, a volume knob)?
  • How many mics will I need to use at any one time?

No matter what you’re after, OnBuy’s seller community is committed to keeping your studio equipment needs well catered to with its dynamic range at unbeatable prices. From premium-quality audio interfaces to sound mixers, speakers, amplifiers and much more, OnBuy is brimming with options to help transform your favourite recording spot into what will feel like a professional studio.
