Audio Interface Buying Guide

Best Audio Interface

1. DAW software and Operation System Compatibility

For a general heads-up, DAW means Digital Audio Workstation, which is the software to help you arrange music. A rule of thumb here is that the first thing you need to know and see if your DAW is compatible with your audio interface before you plan to purchase one. You need not have to Google and search for the number of lists out there, rather read the manual for the audio interface that can easily be available online too. There are two more options to see this –

  1. See if the company you are planning to get the audio interface from also sells DAW or not.
  2. At times seller could also provide a package deal of audio interface with DAW, see if you could crack a deal like that.

However, it should not be a cause of worry for you since most of the high-quality audio interfaces are compatible with some of the famous brands of DAWs like Logic, or Ableton.

Once you have understood about your device’s compatibility with the DAW, check for the interface’s compatibility with your Operating System. These days, all devices are compatible with both Mac OS as well as Windows; however, there are some that support only one OS. So check that before you plan to buy one.

2. Computer Port

Aforementioned, your audio interface will work as the catalyst to connect your computer to the speakers. Hence, many times, the cable type of the audio interface might connect to your computer, but sometimes it might not.

Here is a list of 3 of the most widely used connections for an audio interface:

  1. USB Port – USB audio interface connection is the most widely used connectivity for home studios as well as for bedrooms. It comes at an affordable price. All computers have a USB port.
  2. Firewire  – Firewire is not quite a common option for most audio interfaces as it mostly comes with the high-end models. However, it allows for a faster data transfer.
  3. Thunderbolt – This is one of the freshest connectivity ports with audio interfaces but is gaining high popularity. It is compatible with both MAC as well as Windows.

3. Inputs and Outputs

For connecting to any audio interfaces, one needs to understand what type of interface is required. And for this, you need to specifically understand the input and output channels to connect your interface for good sound recording. For instance, you cannot connect your piano with a TRS microphone input. Hence it is important for you to understand which channel your audio interface.

Input Channel

  • Microphone Input: Allows you to connect your audio interface directly into a microphone.
  • Line Input: Mostly used for microphones or instruments such as the guitar.
  • MIDI Input: Used for MIDI-based keyboards and keyboard controllers.
  • DI Input: Used for live instruments such as guitars or bass.

Output Channel

  • RCA: A popular channel with a most audio interface, recognized by its white and red cables.
  • TRS: Left and right cables so as to allow connection to speakers to separate it.
  • MIDI: Used for MIDI-based keyboards and keyboard controllers.
  • XLR: Used typically for mixers.

If you’re a beginner, a simple interface with the microphone, DI and MIDI inputs are your basic necessities. For outputs, all you need basically is an RCA output that can connect to a studio monitor.

4. Sizes and Portability

There are two common shapes of most audio interfaces.

  1. Desktop – They are compact in size and easily portable.
  2. Rack Mounted – They are slightly heavier and longer and require a rack-mounting desk.

Desktop size is mostly for beginners and for the home setup, while rack-mounting size is for the professional studio setup.


Aforementioned, having a good audio interface is beneficial for high-quality sound recording and production. With an in-depth understanding of its key features and factors, buying the best audio interface for yourself in the market is going to be a cakewalk for you.
