The 7 Best Portable Audio Interfaces (2026)
Let’s compare these in more detail.
1. Focusrite Scarlett Solo 4th Gen
When looking at audio interfaces that have both great quality and a great price, Focusrite Scarlett is usually at the top of the list. Focusrite Scarlett Solo (4th gen) is a great little portable audio interface that’s perfect for anyone looking to get a nice recording wherever they go.
It’s equipped with 2 simultaneous I/O with one XLR, one ¼” jack, and a split ¼” line out. It also has a USB 2.0 and USB-C connection for easy connection with any computer or tablet of your choice, iPads included. You can control the gain with halo technology, essentially giving you an easy visual aid in the form of the LED light around the knobs that control gain, which turns red when you go over the line with your gain.
It has phantom power, so you can preamp anything that you can record while keeping the sound quality you need. It’s light, compact, and in an aluminum shell, so it’s very road-friendly. Best of all, the new ultra-low-noise mic preamp is the bread and butter.
2. Behringer U-PHORIA UM2
The Behringer U-PHORIA UM2 is a compact, and affordable audio interface with several options included. It comes with a combo XLR and TRS inputs, as well as a stereo output and a monitor output for headphones. This budget-friendly audio interface is bus-powered, so you won’t need any additional power outlets apart from your standard USB socket through which you connect it to the computer.
It’s equipped with phantom power (48v power) and easy to use interface, as it has only three knobs through which you can control the whole thing easily. This is just what you need if you’re looking for a cheap, reliable option to have with you. It’s sturdily built and can easily take traveling with you wherever you go.
3. RME Babyface Pro FS
The RME Babyface Pro FS is the pro pick for recording away from a fixed studio. It runs from a suitable computer USB connection, so your travel setup does not depend on a separate mains adapter. Two XLR microphone preamps and two additional analog inputs cover a compact vocal-and-instrument session, while optical digital I/O offers room to expand when you return to the studio. Its small metal housing is easy to pack, though the separate breakout cable is worth keeping with it.
This is a premium choice, but the appeal is practical: bus power, flexible routing through RME’s TotalMix FX and dependable access to the same interface at home or on the road. It is more to learn than the simple one-knob models here. If you only need one microphone and a guitar, the Scarlett Solo or RØDE AI-1 is a lighter, simpler option.
4. Rode AI-1
The Rode AI-1 is a highly portable and stylish USB Audio Interface that is very simple to use and features a 2-button design to simplify it even further. Of course, it is a 1-channel interface so if you want something more versatile, you’ll have to look for it somewhere else.
This interface has an XLR combo input with 48-volt phantom power and supports mic, line, and instrument-level inputs. It does have a 1/4-inch monitor/speaker output so if you want to connect one, you can. Being USB bus-powered, this is an interface for musicians and producers on the go, and it’s compatible with both Mac and PC.
Above all this, the Rode AI-1 is extremely affordable so if budget is your main limitation, I highly suggest you look into this option.
5. PreSonus Quantum ES 2
The PreSonus Quantum ES 2 steps up from the basic budget interfaces when you need two microphone preamps in a compact rig. Its two combo inputs, USB-C connection and balanced stereo outputs suit a pair of microphones or a singer with an instrument. The MAX-HD preamps offer plenty of gain for a range of microphones, while the front-panel Auto Gain and meter help when you are setting up without an engineer.
You also get a headphone output and MIDI I/O through its 3.5 mm Type-B connection, so a keyboard or drum machine can join a travel setup with the appropriate adapter. The ES 2 can run from a suitable USB-C port, but some computers and mobile devices need auxiliary USB-C power. Check your port before relying on bus power at a rehearsal or gig. It costs more than the UM2, and its extra preamp capability makes sense when the cheaper single-mic options feel limiting.
6. Audient iD4 MKII
The Audient iD4 MKII is another USB Audio Interface. It’s a 2-in/2-out interface that features a microphone preamp, a JFET instrument DI, and two headphone outputs, and comes with the ARC software suite with DAW, virtual instruments, plug-in FX, and more!
With a 4-knob design, this interface is incredibly easy to use and navigate so on-the-go musicians will have no problems. Plus, it’s bus-powered so no additional power supply is needed. You can connect guitars, basses, or keyboards, essentially everything a producer/musician needs.
7. Arturia MiniFuse 2
The Arturia MiniFuse 2 is yet another portable 2-in/2-out USB-C Audio Interface with a simple design that is easy to use. It comes at a really affordable price so anyone can afford it. This interface comes with a huge software bundle that includes Ableton Live Lite, Analog Lab Intro, Auto-Tune (subscription), GUITAR RIG 6 LE, and Splice (subscription). All things considered (especially the price), this is a pretty good deal.
Mac and PC compatible, the Arturia MiniFuse 2 features a traditional 5-pin MIDI DIN I/O for synths and drum machines, a stereo virtual loopback channel, two mic/instrument/line combo preamps with phantom power, and a headphone out. Best of all, it’s compatible with USB 2.0.
Should you get a Mixer or Audio Interface?
When you think of a recording studio you usually think of a huge mixer and an engineer masterfully moving the sliders on it. But in reality, you don’t necessarily need a large hardware mixer.
Software development has made sound mixing digital. Sure some people still like doing it the old way with an analog mixer, but as a minimum, all you need is a simple audio interface to connect and transform your analog signal into digital for your computer to read. After that, you’ll just have to mix everything in your DAW (digital audio workstation software, such as Logic, Pro Tools, Ableton Live, etc).
Also, you should know that some of the mixers on the market today act as audio interfaces as well, so if you’re looking for it, you can get a 2-in-1 option as well.
What does an audio interface do?
An audio interface is, to put it simply, converting your sound from analog into digital so that your computer can read it. It’s necessary if you want to record your sound through your computer with decent sound quality.
How many inputs/outputs do I need?
The number of inputs depends on how many things you want to record at once. If you’re a singer/songwriter, you’ll probably need just two (one for your mic and one for the instrument). If you want to record more, you’re going to need more inputs (as for more instruments or mics at once).
As for the outputs, you should look out to have at least one stereo output, as well as a headphone/monitor out, to ease up your recording sessions.
Does the interface affect sound quality?
Since the audio single will be going through your interface, it has the potential to affect the signal. Ideally, your audio interface will record a clean signal. If you invest in a decent-quality interface, then the sound quality should be good. If you buy a low-quality audio interface, then you may get noise and distortion introduced into the signal.
Do I need phantom power?
If you have equipment that does need phantom power, then your audio interface will need phantom power. The most common items that people have that need phantom power are condenser microphones. Check your equipment before buying an audio interface to make sure it suits your needs.
Can I use a USB mic instead?
Sound quality recorded through a mic and audio interface is almost always a lot better than using USB mics. However, USB mics are better than nothing and they may suit your needs.
Summary
If you want to record multiple instruments at the same time, then you need to make sure that you have enough inputs. Also, be sure that you have enough outputs for your needs (e.g. mixing desk, routing to other gear, in-ear monitors, etc).
Also, you may require phantom power depending on what gear you’re using, such as condenser microphones, be sure to check the specs of the interface before buying.
My top portable audio interface pick is the Focusrite Scarlett Solo 4th Gen. This is the most popular and all-around choice out there.
My budget portable audio interface pick is the Behringer U-PHORIA UM2. If you want to spare your pockets but still have a decent audio interface then this is the one.
