If you are using XLR microphones for recording podcasts, you need a USB audio interface. USB microphones are connected directly to your PC, but XLR mics record the audio as analog signals that need to be converted in digital signals for your computer.
Now even the sound card in your computer can do the job, but it fails to give you professional and distortion-free audio that you need for podcasting. Even a cheap audio interface upgrades the sound quality of your recordings better than a sound card.

Buying Guide for Selecting the Best USB Audio Interface For Podcasters
USB audio interface comes in great variety. They differ in the price range, and the difference lies not only in their quality, but also the option they provide. So here are a few things that you should consider while selecting an Audio Interface for podcasting.
• Number of Inputs
Before you buy the audio interface, you need to be sure of what you need. The first thing to consider is how much input you need to connect with the interface.
Now that depends on the format of your podcast and what you do. If you are a solo host, you may not need a very sophisticated system. You can simply buy a one-line interface and go with the recordings. That saves money, and it is pretty simple to handle as well.
If you intend to interview people or have a co-host of some sort, then you will be using more than one microphone. That means you should carefully gauge the needs before selecting how much mic preamps your audio interface should offer. You have 1-8 inputs to select from. So basically you need to select an audio interface depending on the number of mics you will be using.
Also, inputs are for inline or instruments. If you are playing music for your podcasts, you should consider the instrument inputs as well.
• Phantom Power
You will need 48-v phantom power. Condenser microphones need to be powered. Unless you are using a dynamic mic, you need to charge your microphone with phantom power coming from your audio interface. Almost all USB audio interfaces offer 48 volts phantom power, but still, you need to double-check before you select one.
• Number of Outputs
Not only you will be recording the podcasts and sending it to your PC, but you might want to listen to the recording in real-time or afterwards for processing. So you need to consider the outputs that an audio interface is offering. Also, it is convenient to have a volume control option with the headphone output for adjusting the volume right from the interface.
If you want to incorporate additional hardware, you need to consider the number of outputs an audio interface is offering.
• MIDI I/O
Not all audio interfaces offer built-in MIDI I/Os. So if you are looking to connect an external keyboard input for synchronization, you need MIDI inputs and output.
Most of these audio interfaces are compatible with more than one system. However, it is still essential to look at specs and see whether a particular audio interface is compatible with the system you use. Once you check the compatibility, you also need to check on the connectivity option. Some of the audio interfaces can be connected with USB-C, 2, or 3. Always check if a particular audio interface can be connected with your PC or other devices.
• Physical Appearance
The physical appearance of the audio interface may matter more than you think whether you will be placing it on your desk or mount it on a rack behind the monitor. You also need to consider the size and weight of an audio interface if you intend to take it along while travelling, or you just need it for studio recordings. So consider all these options carefully before you select an audio interface.
• Special Features
Beside some of these basic features, you might want to look at some special features. For example, if you intend to play instruments like the guitar or piano, the interface should have a special connection for that. You may also need a guitar amplifier. Some audio interfaces offer digital signal processing chips and have built-in mixers. These chips allow you to make use of the audio interface as a standalone device. The price of these audio interfaces can go up high depending on these special features.
The budget is probably the most important factor to consider for selecting the best USB audio interface.
You can get a decent audio interface under $100 easily, but you may not get the number of inputs you require. So a less pricey option may provide fewer inputs that can be limiting.
If you are selecting an audio interface with more line inputs that do not mean you will get a better sound quality. The extra price probably is what you are paying for more inputs. So that’s where it becomes tricky.
Make sure you select the audio interface that only provides the number of inputs you need. The price should be for the quality of sound and low latency and not the number of inputs.
Buying an interface with four inputs is only a waste if you are not going to use that many microphones. You might look for the two mic inputs within the same range and get better sound quality.
Choosing the best USB audio interface is not very difficult if you know your needs. Make sure you choose a good quality audio interface with the right inputs you need. Buying an audio interface with more line inputs that you don’t need would needlessly increase the price and may not give the best quality.
We have enlisted several USB audio interfaces with a variety of options for your convenience. Look for the one that provides enough inputs and outputs that fits in your budget.
