The truth
beyond fidelity

The inspiration beyond practicality.

Experimenting, composing, recording and producing. The fundamental aspects of what you do in your studio are the same as in the most illustrious professional studios. With AudioFuse, Arturia lets you match the quality and effectiveness of professional setups, so you can make sure your sound is always handled with the greatest care, no matter where it comes from and where it goes.


Once you've heard your sound through AudioFuse, nothing will ever compare.

As musicians, we invest a lot of time and energy into our sound, and AudioFuse treats it with the respect it deserves

DiscretePRO® Preamplifiers

First, we designed our own microphone preamps from the ground up. We decided not to use any third-party integrated operational amplifiers, in order to have total control over the performance of each component. Inspired by the classic designs of the golden age of analog, we used our cutting edge technology to enhance the latest generation of discrete components. One listen and you'll never look back.

Professional Converters, Reliable Clock

WWhile preamps are critical, the resulting analog signal has to be converted to the digital world for your computer, tablet, or phone. To attain this, we chose the AKM® premium series converters, known for their outstanding quality. Another factor that distinguishes between budget and high-end digitizing is timing accuracy. That's why we built our reference clock on an exceedingly accurate, fully temperature-compensated oscillator with outstanding 20ppm stability. We even paired it to a sophisticated clock recovery and jitter elimination system to ensure that you get the pristine sound you demand, whatever the conditions.

Internal Design

It’s a well-known fact that the quality of an audio chain is never stronger than its weakest link. That's why we built AudioFuse with obsessive attention to detail at every stage, including a fully symmetrical and nearly capacitor-free input stages. Unlike most interfaces on the market, we didn't compromise audio quality by combining preamp and line in with an attenuator—they're separate signal paths. There's no breakout cable to degrade signal either—all connections are solidly onboard. Next-generation analog/digital converters deliver audio with startling transparency at sampling rates up to 192kHz. We even designed custom built potentiometers to our exacting specs. Sound serious? It is.

fast workflow

You can't stop time ticking away, but AudioFuse can help you save some.

AudioFuse lets you get straight to the point, keeping you motivated by goals and not constrained by limitations.





01. Input channels direct controls

The 2 main input channels feature superb controls that let you get the best out of whatever source you're recording. From reliable, constant 48V phantom power to feed your most precious condenser microphones to a multi-level pad to make even the hottest signals usable, the inputs also feature auto-sensing impedance matching. You can also quickly phase-invert the incoming audio to correct any issues before it hits the mix.

02. Monitoring section

The ultimate monitoring station, AudioFuse gives you immediate access to functions that you're probably more used to relying on your DAW to provide. Easily mute, dim, or sum your mix to mono, and quickly flick between 2 sets of reference speaker at the touch of button. You'll also fall in love with the simple but effective direct / computer signal mixing knob.

03. Phones section

AudioFuse has two independent headphone outputs, each with their own volume control. Because quality, workflow, and connectivity is what makes AudioFuse unique, it features ¼” jack and mini jack ports on each channel so you can plug in and monitor, and not have to search for those ever-elusive adaptors.

A perfect control center (AFCC)

Beneath the intuitive, hands-on control on the surface of AudioFuse lies the power and versatility of a pro studio.

AudioFuse allows you to keep on top of your projects, so you can feel confident no matter what musical scenario comes your way.

As the next-generation audio interface, AudioFuse lets you access a large number of fundamental features directly from its top panel. Once it's connected to a computer, AudioFuse transforms into a full-featured mixing console.

AudioFuse Control Center controls the mixer, selection of inputs, routing, monitoring, and additional functions such as sampling rate, Clock Source, Pad, Cue, and more. Another useful touch is that AudioFuse will remember the latest AFCC settings for standalone use until the next time you connect and change them.


Connecting people is vital to help them reach their full potential. It is also true for music gear.

Analog Inputs

AudioFuse gives you exceptionally high quality analog inputs that capture every nuanced detail. In addition to line-level signals, the two XLR combo-jack inputs on the front let you record high impedance instruments like electric guitars and basses, as well as your microphones. AudioFuse can take anything you throw at it, and reveal every subtlety. Do you need more? The ¼” TRS jacks and RIAA, grounded phono RCA inputs let you add two line level instruments or a turntable for recording or scratching your vinyl LPs.

Digital IO

AudioFuse is the master of the digital realm. Beyond its main Plug & Play USB connection letting you connect AudioFuse to your computer, tablet or phone, you will find optical or coaxial S/PDIF I/O to link it with your HIFI devices. You can use AudioFuse together with other ADAT-enabled equipment to give your inputs and outputs a boost, too. Easily bank up an extra set of mic pre-amps and record a whole band at once. AudioFuse also features innovative, space-saving breakout MIDI connections, opening up a whole new world of exciting sounds, outboard synths, and sound modules to your setup.

Analog Outputs

To get the best idea of how your music truly sounds, you'll often need to compare multiple sets of reference monitors and speakers. AudioFuse features 2 sets of line outputs so you can quickly, efficiently send your mix to different monitoring systems to make sure your mix translates well. The amazing output options don't stop there, AudioFuse has two separate headphone ouputs with both 6.3mm and 3.5mm so you'll never have to hunt for adapters again. These outputs can also be put to great use on stage, but also for advanced techniques in the studio, too. The huge reamping possibilities of AudioFuse are truly inspiring, letting you track your dry signal while simultaneously sending it - impedance corrected - to a guitar amp for recording.

Additional IOs

Potential, effectiveness, and convenience all play a part in how your musical project will progress. AudioFuse gives you all the tools you need to make the most of any situation. For example, processing your sounds through outboard effects units, pedals or modules is quick and easy when you have two insert connections. Connecting your USB controllers or dongles without running out of USB slots on your computer simply isn't a problem anymore thanks to its built-in USB hub. You also want to directly control vintage synths or drum machines? MIDI IO at your service! Last but not least, the word clock IO will ensure that all of your equipment stays perfectly in sync.


The most diverse, adaptable, and versatile interface around.

Unlike jamming musicians, computers find it hard communicating audio across different systems. No problem, AudioFuse will be their interpreter.

Compatibility with all platforms

Professional and flexible, AudioFuse can work with any system, whether on PC or Mac. When you need to record on-location and capture those moments of inspiration, connect to iOS and Android. No matter what your device, AudioFuse brings you musical world together and keeps everything simple.

Plug & Play & No specific drivers

No fiddly driver installations - we’ve made the decision to use generic drivers and worldwide USB 2 to ensure you're always ready to record, unlike proprietary drivers that need to be developed and maintained after each operating system update. It's solid, reliable, and lets AudioFuse perform its best at all times with the bandwidth you need and the unnoticeable latency you expect.

Green modes

AudioFuse features 4 power modes, including 'Green Mode', to save your laptop battery life. When connected and powered by USB, AudioFuse will automatically function at an adjusted resolution to give you crystal clear recording and playback with lower power requirements. Record, perform, and mix anywhere.


For the recording musician, from the moment you strike your instrument or sing a note, you want to hear it back immediately. AudioFuse features exceptionally low latency as low as 3ms depending on your set-up, with a frequently measured value of 4.5ms on a wide range of computers. It allows musicians to never lose their feel and vibe. The class-compliant driver alongside the carefully designed internal signal flow from input to output stage delivers near real-time results.


Two AudioFuse units can be connected to each other via ADAT to double your I/O count. This is particularly useful for the engineer looking to record a larger band setup. Not only do you have more inputs, the signal path continues to be at immaculate audio resolution.

Why USB 2.0?

Our rigorous testing continuously provided the best results over USB 2.0, confirming that the bandwidth requirement were met and exceeded with this format. In fact, the latency performances were favourable too, so to meet our mission of providing the best and fastest interface this is the connection to meet these results.


AudioFuse treats your signal with respect, so you can enjoy every last, tiny detail whether recording or listening.

With the AudioFuse in your backpack, your studio is everywhere. You're free to explore and take some time to create.
