Audio interface vs. mixer
What is an audio interface?
An audio interface is a crucial piece of gear for any home studio. It takes audio via its inputs, usually XLR or 1/4-inch jack, and passes the audio to your computer while preserving the quality. This makes it an essential tool for recording music, podcasts, or any other audio projects you might have.
To get the audio to your computer as clearly as possible, audio interfaces come with built-in preamps. These preamps boost the audio signal from your microphones or instruments to a level that can be recorded clearly. This ensures your recordings are crisp and detailed, capturing all the nuances of your performance.
You’ll find audio interfaces with different numbers of inputs. If you’re just recording vocals or a single instrument, a simple two-input interface might be enough.
However, if you plan to record a band or multiple sources at once, you’ll need an interface with more inputs to accommodate all your gear. Interfaces typically have an even number of inputs to accommodate stereo recordings and instruments.
They’re typically used in home studios or small project studios, ideal for solo musicians, podcasters, and producers who need high-quality recordings without investing in a full mixing console.
Most audio interfaces can also be expanded using ADAT, giving you more freedom in terms of inputs. Their compact size and affordability make them accessible for anyone looking to improve or start their recording setup.

Pros and cons of an audio interface
Pros | Cons |
---|---|
High-quality sound preservation | Limited inputs on smaller models |
Built-in preamps for clear recording | Requires a computer to function |
Tend to be compact and affordable |
Recommended audio interface brand: Subzero
SubZero interfaces are ideal for beginners as they boast excellent preamps, robust build quality, and user-friendly software – all at an affordable price point. They’re available either on their own or as part of a bundle, including items such as headphones, studio monitors, microphones, and reflection filters.
What is a mixer?
A mixer is a versatile piece of equipment that gives you control over your audio. With an array of dials and sliders, it allows you to adjust various aspects of your audio such as volume, tone, and effects.
Usually associated with live music, a mixer often boasts at least 32 inputs. It will also host various auxiliary outputs, allowing you to send different mixes to stage monitors or IEMs for performers to be able to hear themselves.
Mixers come in several types: analogue, digital, USB, and hybrid. Analogue mixers are known for their warm sound and straightforward operation and are more commonly associated with expensive recording studios.
Digital mixers offer advanced features like preset storage, precise control, graphic displays, and touch screens. The Zoom LiveTrak L-6 is a great example of a digital mixer that can be used in a variety of environments. It can record up to 10 tracks with 32-bit float recording and doubles up as an audio interface with 12-in/4-out capability.
USB mixers are simplified, can connect directly to your computer and combine the functions of a traditional mixer and an audio interface. Hybrid mixers blend the benefits of both analogue and digital technologies, offering flexibility and a broad range of features.
As well as live sound environments, such as concerts, theatre productions, and live broadcasts, where they’re most commonly used, mixers are also essential in larger recording studios in which multiple audio sources need to be managed simultaneously. A mixer’s ability to handle multiple inputs and outputs makes it ideal for complex setups involving several microphones, instruments, and other audio devices.
Pros and cons of a mixer
Pros | Cons |
---|---|
Greater control over audio | Can be bulky and heavy |
Suitable for live and studio use | Complicated so requires a big learning curve |
Various types for different needs | More expensive than basic interfaces |

Do I need an audio interface or a mixer?
What will you use it for?
An audio interface is ideal for recording music, podcasts, or any project requiring high-quality digital audio. It connects directly to your computer and is straightforward to use, making it perfect for home studios or small projects.
In contrast, a mixer is better suited to live performances, complex recording sessions, or situations where you need to manage multiple audio sources simultaneously. It provides hands-on control with dials and sliders, which can be crucial in dynamic environments like live shows or large studio setups.
Inputs and outputs
Evaluate the number of inputs and outputs you need. Audio interfaces typically offer a limited number of inputs, making them suitable for solo musicians or podcasters. If you only need to record a couple of microphones or instruments at once, an interface with two to four inputs might suffice.
Mixers, however, can handle many more inputs, making them ideal for bands or larger recording setups. They allow you to connect multiple microphones, instruments, and other audio devices simultaneously, providing greater flexibility.
How much control do you need over your sound?
This is one of the key questions you need to ask when deciding between an audio interface and a mixer. Audio interfaces offer basic control, often through software on your computer, making them user-friendly for simple recording tasks.
Mixers, on the other hand, have dials and sliders that provide extensive control over various audio aspects like EQ, panning, and effects. This hands-on control is beneficial for live sound environments and detailed studio work, where real-time adjustments are essential to achieve the desired sound quality.
Effects
If you want to add effects to your audio, a mixer would be the best option. Audio interfaces usually rely on software-based effects, which can be powerful but might not offer the immediacy and tactile control of a mixer.
Many mixers come with onboard effects like reverb, delay, and compression, allowing you to shape your sound directly on the device. This is particularly useful in live settings, where quick adjustments are necessary. If you prefer hardware-based effects and need to be able to tweak them in real-time on the fly, mixers are the winner here.
FAQs
Which is better, an audio interface or a mixer?
Audio interfaces are better for a simple studio setup in which you need to record high-quality audio, whereas mixers are better for more complex setups, both in the studio and live, where you need more extensive control over multiple audio sources.
Do you need an audio interface for mixing?
You do not need an audio interface for mixing if your setup includes other sufficient tools. However, an audio interface enhances sound quality and reduces latency, making it a valuable addition to professional mixing.
Can a mixer replace an audio interface?
A mixer cannot fully replace an audio interface due to its different functions. While a mixer offers control over audio inputs and outputs, an audio interface ensures high-quality digital conversion. Both can complement each other in a comprehensive audio setup.
