5 Criteria to Look For Before Buying a Universal Audio Audio Interface
Key buying criteria so you get the right fit the first time.
Input Count vs Simultaneous Sources
Input count should be set by your worst-case recording session, not your average one: it's the maximum number of separate sound sources you'll ever need running at the exact same time. A single-input interface handles a solo vocalist fine, but an interview or duet needs two inputs simultaneously regardless of how often that happens.
Preamp Gain and Noise Floor
A preamp boosts a microphone's naturally quiet signal to a usable recording level, and how much clean gain it provides before introducing audible hiss determines whether quieter microphones sound clear or noisy. Interfaces with 55 to 60 dB of clean gain comfortably handle most dynamic and ribbon microphones without noticeable hiss. Check the specific gain figure in dB and cross-reference it against the microphone you actually plan to use.
USB vs Thunderbolt Latency
Connection type affects real-world recording latency more than most buyers realize: USB now delivers latency low enough for real-time monitoring in the vast majority of home setups, while Thunderbolt's lower latency mainly pays off in larger multi-channel professional rigs. Check for a stated round-trip latency figure at a standard buffer size before assuming Thunderbolt is worth the added cost for your setup.
Bit Depth and Sample Rate
Bit depth determines the dynamic range of your recording, with 24-bit now the professional standard and a meaningful step up from older 16-bit recording in headroom before clipping. Sample rate, typically 44.1kHz to 192kHz, determines how many times per second audio is captured, with higher rates capturing more high-frequency detail but diminishing practical benefit for most home recording. Check that your interface supports at least 24-bit/48kHz.
Bus-Powered vs External Power Supply
Whether an interface is bus-powered, drawing power from the USB connection alone, or requires a separate power adapter changes how portable and simple your setup actually is. Compact 1-2 input models are usually bus-powered, while higher-channel-count interfaces more often need external power. Check the listing specifically rather than assuming a fully portable, single-cable setup.

You're recording a single source, where Focusrite Scarlett Solo 3rd Gen USB-C Audio Interface already covers the job at the lowest price here.
Frequently Asked Questions
Do I need an audio interface if I already have a USB microphone?
No, a USB microphone already contains its own basic audio interface internally; a separate interface is only needed if you want to use an XLR microphone, record multiple sources at once, or want better preamp quality.
How many inputs do I actually need?
Count the maximum number of separate sound sources you'll realistically record in a single take, not your total microphone collection; a solo vocalist typically needs just one input, while an interview needs at least two.
Is Thunderbolt worth it over USB for a home studio?
Usually not for a 1-2 input home setup. USB now delivers latency low enough for real-time monitoring on most systems, and Thunderbolt's main advantage mostly matters for larger professional multi-channel setups.
What does 'bus-powered' mean on an audio interface?
It means the interface draws power directly from your computer's USB connection, so no separate power adapter is needed, simplifying setup, especially useful for a portable or minimal desk arrangement.
Do I need 24-bit or is 16-bit enough for recording?
24-bit is the current professional standard and gives meaningfully more headroom before clipping than 16-bit, and the vast majority of modern interfaces, including entry-level models, now support it by default.
Can I use an audio interface with my phone or tablet?
Some interfaces support mobile devices via USB-C, but check the specific listing for iOS or Android compatibility and power requirements, since not every USB interface is designed to draw power correctly from a mobile device.
