Understanding Audio Interface

Updated: May 30, 2021


What Is An Audio Interface?


An audio interface is used to make good quality home studio recordings. It’s an external sound card with inputs for mics and instruments.


What is sound card?


A sound card is an expansion card for producing sound on a computer that can be heard through speakers or headphones. Although the computer does not need a sound device to function, they are included on every machine in one form or another, either in an expansion slot (PCI) or built into the motherboard (onboard).





If you want to know what is an audio interface, then you probably mean how can I record my …. voice, guitar, keyboard, Ukelele, or anything else that makes a sound! So you know you probably need an interface … but you need to know more!






Because an audio interface is, quite simply, what you need to get sound in and out of your computer. If you want to make a good quality recording of your voice or any instrument and hear the results so that you can mix and master your recordings, you will need an audio interface.


You can make basic recordings with any modern computer, laptop or tablet as they all come with a built in sound card. You can improve the sound of your recordings to some extent, especially on phones and tablets, with a better microphone. However to really make a professional recording you will need an audio interface or a better sound card.


Below is some detailed info about what is an audio interface, and what it is used for, then we also have a detailed post on how to choose the best audio interface for you.


Is an audio interface the same as a sound card?


Essentially yes, a sound card and an audio interface do the same basic job. To get sound in and out of your laptop, pc, mac, tablet so that you can process and edit it you need something that turns the sound into a digital signal and back again. That’s what the sound card or interface does.


Basically, an audio interface is an external sound card, perfect for laptops and tablets, and now widely used by people with desktop computers too. Gone are the days when the only way to improve your recordings was to fit a new sound card inside your machine.


You can almost certainly already record and playback with your laptop, pc, mac or tablet, but buying an audio interface will take you one step towards sounding more professional.
