You’ve got the microphones, guitars, and keyboards. You’ve got the computer. Now you just need to get them talking. That’s where the best audio interfaces come in. As the conduit between the analog and digital worlds, your audio interface is one of the most important pieces of equipment in the chain of content creation. Whether you’re recording or livestreaming, your interface determines the signal quality you capture and amount of creative flexibility you have. Conversion rates, inputs and outputs, and portability/expandability are just some of the considerations when picking an interface. But you don’t have to scroll through specs trying to make sense of it all. We’ve surveyed the market and picked some of the best audio interfaces to meet your needs no matter the scale of your projects or budget.

How we selected the best audio interfaces

Audio interfaces come in a vast array of configurations and we selected models based upon the most common needs of content creators, musicians, livestreamers, and podcasters. Many of our selections are outfitted with super-versatile combo inputs that accommodate XLR and 1/4-inch connections that are compatible with most microphones, instruments, and line-level devices like keyboards. Connectivity is also an important factor in determining the usefulness and system-compatibility of audio interfaces; we selected a variety of units that use either USB, Thunderbolt, Lightning, or some combination thereof. Interfaces with fewer inputs are naturally smaller and better suited to portable use, while interfaces with more inputs are ideal for large-scale studio use and usually have designs that reflect this. This list represents the whole spectrum, with the most portable single-input interface at one end and the most expandable 26-input, 26-output interface at the other. Finally, high analog-to-digital conversion bitrate and recording quality are essential features to look for when selecting the best audio interface for professional use. If you intend to use audio recorded through your interface for any production-level application, be it streaming, film scoring, or podcasting, industry standards favor using the highest-available quality of audio, which is generally a depth of 24 bits and sample rates of either 96 kHz or 192 kHz.

Still, if you’re able to work within its limits, the AudioBox is a great value.

    Things to Consider Before Buying an Audio Interface

    How many inputs do you need?

    Audio interfaces come in a broad range of input numbers, so it’s important to select a unit that fits the type of content you’re creating. Single- or double-channel audio interfaces should be sufficient for basic streaming and podcasting work, but musicians should opt for four or more inputs to avoid being painted into a corner creatively. An eight-input interface is the best place to start in terms of flexibility, but keep in mind that those units aren’t as portable as a two-input design.

    What type of audio are you recording?

    Most of the units on this list include specially-shaped combo inputs that can accommodate both XLR and 1/4-inch TRS connectors, allowing a variety of microphones and instruments to be used and which will provide the most flexibility in working environments. Compare the type of audio equipment you’re looking to capture with an audio interface’s inputs can save a lot of headache down the line; for example, the iRig HD 2 is a convenient single-input interface, but it’s not compatible with microphones.

    Do you need portability?

    The most portable audio interfaces tend to have a maximum of two inputs, with some models offering expansion via their ports. To maximize the portability factor, choose an audio interface that’s powered via its own connection to the computer. This type of design limits the need for extra electrical wiring, and it also allows you to record remotely using only the battery of a laptop.

    Do you need expandability?

    If you’re aiming to build a studio or expand your production in the future, choose an audio interface with ADAT optical inputs like the PreSonus Quantum 2626. A single ADAT port generally allows interfaces to accept an additional eight channels of audio from another compatible dedicated unit over a simple optical cable, effectively doubling or even tripling the capacity of a base model eight-input interface.

    FAQs

    Q: Are expensive audio interfaces worth it?

    The more you spend on an audio interface, the more likely it is to have high-quality analog-to-digital conversion, efficient design, and expandable I/O. That said, you don’t have to break the bank to achieve good results. The relatively affordable Focusrite Scarlett 2i2, for example, has the ability to record at a very high 24-bit/192 kHz quality (a resolution that satisfies the expectations of mastering engineers and lossless streaming services like Apple Music, etc.). Still, it’s limited to only two inputs. Whether a more expensive audio interface is worth it to you comes down to whether you value capacity, expandability, and futureproof design.

    Q: What makes one audio interface better than another?

    Audio interfaces combine many critical components in a single unit including analog-to-digital conversion and preamplifiers. The best audio interfaces tend to be the most flexible and can accommodate a range of input types from condenser microphones to keyboards. The more expensive an audio interface is, the more options for expandability it should offer.

    Q: How long does an audio interface last?

    There’s no real limit on the lifespan of an audio interface beyond the deprecation of its connector type. For example, Apple recently stopped designing computers with FireWire ports, which used to be commonly found on audio interfaces for the better part of a decade. These devices can still be used with an adapter, but if you’re looking for an interface with staying power, pick one with a newer connector like Thunderbolt or USB-C.

    Final Thoughts

    Whether you’re livestreaming, podcasting, making music, or recording voiceovers, an audio interface is an essential piece of gear for connecting analog audio equipment with your computer. When shopping for the best audio interface for your needs, keep in mind the number of simultaneous inputs you’ll require: a two-input unit like the PreSonus AudioBox USB may be sufficient for a streaming, vocal, or podcasting setup, while an eight-input interface like the PreSonus Quantum 2626 is better suited for recording a full band. Mobile recordists may also prefer a bus-powered audio interface like the Focusrite Scarlett 2i2, which allows you to record on the go without the need for an external power supply. Regardless of your end goal, it’s important to pick an audio interface that matches the scale of your studio and accommodates your needs for portability, expandability, and audio quality.
