What is an Audio Interface?

An audio interface is a hardware device that manages the inputs, outputs, and sound processing of your audio equipment. A typical audio interface looks like this:

An audio interface converts acoustic sound. For example, it takes your microphone’s analogue signal and converts it into a digital signal that your computer reads and processes. The same thing happens for any XLR input device like a keyboard, guitar, and so on.

Why You Might Need One

Microphones and other different types of audio equipment often use XLR inputs. Devices like this need audio interfaces to convert the signal (unless you’re using a USB device, then it’s not needed).

Sound cards that come built into computers aren't equipped to perform the types of high-demanding sound processing from your audio equipment. For example, higher quality microphones require more power to convert the signal and power it up to line level (which is the correct volume level). This is known as phantom power, it’s a way of giving your equipment enough power to function. Audio interfaces usually come with this tool built in, so it’s just a button press to enable for your devices.

What to Look for When Buying a Podcast Audio Interface

If you’re coming into this completely fresh, then chances are you don’t know the types of things you need to look out for when buying your own podcast audio interface. Here is a checklist of things to look out for.

Price

For casual podcasters, its best to start off relatively cheap or stretch out to medium-priced audio interface that balances good quality and cost. If you plan on taking your setup to the next level, then you will have to invest more money. The more you spend, the more professional your higher-quality your audio will be, like with the Behringer U-Phoria UMC22.

The UMC22 has pretty much what you need for a one man show. It has a one XLR input for your microphone, one for an instrument, phantom power option, USB connection to go to your computer, headphone jack to monitor your audio, and mono jack outputs for the two inputs.

If you want sound professional without spending much money (and let’s face it, who doesn’t), Behringer U-Phoria UMC404HD with 4 channels is probably the best option that we’ve seen so far. They’re not too expensive and have a fair few options for podcasters to tweak audio live to reduce post-production editing.

If you plan to do podcasting regularly, it is better to invest in a higher quality audio interface. The Scarlett 2i4 (2nd Gen), you can amplify your quieter moments without any unwanted hiss or buzzing, operates at sample rates all the way up to 192kHz.

The solid build quality, clear sound, and low latency make the Scarlett 2i4 (2nd Gen) a good option for an inexpensive entry-level audio interface for recording guitars and vocals, especially for beginners.

Mic Inputs

If you are going to have live sound while recording or are creating your podcast as a team, you will need to consider the number of inputs your audio interface requires. If you are going to record tracks and solos, an audio interface with just one input should be enough.

If you are limited by audio inputs, recording using tracks is a simpler way to get started and know how sound flows work. This allows you to compose your episode and rearrange the audio for a more professional-sounding podcast.

Phantom Supply

As mentioned earlier, phantom power is the way in which you power your audio equipment. If you are going to use condenser microphones you definitely need phantom power (aka +48V). 

Most modern audio interfaces include this functionality, but it’s one to watch out for.

Outputs

All interfaces come with at least one stereo output to connect your monitors and listen to the audio played. If you require outputs to multiple systems to reference your productions, in the same way it is important that you choose an interface with a sufficient number.

Connectivity

Previously FireWire 400 or FireWire 800 were the best connections on the market, but currently with USB 3.0 and Thunderbolt gaining popularity, FireWire is less common. If your system supports at least USB 3.0, or if it supports Thunderbolt, it is recommended that you look for interfaces that have this type of connection.
