The classic two-source session, judged on preamp character, instrument input quality, and level help.
The Best Audio Interfaces for Guitar and Vocals (2026)
Two-input interfaces judged for the singer-songwriter session: one mic, one guitar, recorded together.
Our top picks at a glance
Best for guitar and vocals
Focusrite Scarlett 2i2 4th Gen, 2-Input USB Audio Interface (Interface Only)Home studios recording a voice and a guitar, two voices, or a stereo pair.
Best vocal sound
Universal Audio Volt 276 USB Audio Interface, 2-Input with 76 Compressor (Interface Only)Vocalists and streamers who want controlled, finished-sounding takes without touching a plugin.
Best guitar DI
Audient iD4 MkII USB-C Audio Interface, 2-Input (Interface Only)Guitarists and vocalists who record one source at a time and care most about the mic preamp.
For guitar and vocals together, the Scarlett 2i2 4th Gen is the safest buy: two proper inputs, Auto Gain, and Clip Safe for the loud chorus. If the vocal is the star, the Volt 276 earns its premium with a hardware compressor. Guitarists recording direct should also look at the Audient iD4 MkII for its JFET instrument input.
The picks, ranked
Best for guitar and vocals
Focusrite Scarlett 2i2 4th Gen, 2-Input USB Audio Interface (Interface Only)
The default two-input interface, with clipping protection built in.
Two mic preamps, two Hi-Z inputs, Auto Gain, and Clip Safe: the whole singer-songwriter session is covered, including the loud chorus.
Strengths
- Two remote-controlled mic preamps with 69 dB of gain, so quiet mics get enough level without noise creeping in.
- Clip Safe watches the input and adjusts gain if a loud moment threatens to distort.
- Auto Gain and Air mode make good levels easy for people who do not want to babysit meters.
Limitations
- Two inputs is a hard ceiling, so a drum kit or a live band needs a bigger box.
- No MIDI in or out for keyboard controllers.
- A single headphone output means sharing when two people monitor.
What owners report
Commonly praised
- Auto Gain plus Clip Safe together make ruined takes rare for beginners
- two mic preamps handle voice and guitar at the same time with room to spare
- clean sound that stays out of the way of the performance
Common complaints
- Two inputs is a hard ceiling for drums or a live band
- a single headphone socket means two listeners must share
- no MIDI connection for controllers

Best vocal sound
Universal Audio Volt 276 USB Audio Interface, 2-Input with 76 Compressor (Interface Only)
The Volt 2 plus a real hardware compressor for vocals on the way in.
The 76 compressor plus Vintage mode gives a vocal take a finished, controlled sound before any plugin touches it.
Strengths
- The built-in 76 compressor tames loud vocal peaks before they reach the computer, which is hard to fix afterwards.
- Vintage preamp mode plus the compressor gives vocals a finished character straight from the input.
- The wooden side panels and larger knobs make it the most pleasant Volt to use by hand.
Limitations
- The compressor is a single fixed character, not a flexible studio compressor.
- Two inputs only, so it cannot grow into a band setup.
- Costs more than the Volt 2 for one extra feature, so it only pays off if you record vocals often.
What owners report
Commonly praised
- The built-in 76 compressor keeps vocal levels even before they reach the computer
- Vintage mode plus the compressor gives takes a finished feel straight from the input
- large knobs and wooden side panels make it pleasant to adjust by hand
Common complaints
- The compressor has one fixed character and cannot be reshaped like a plugin
- two inputs only, with no room to grow into band recording
- the premium over the Volt 2 only pays off for regular vocal work

Best guitar DI
Audient iD4 MkII USB-C Audio Interface, 2-Input (Interface Only)
One console-grade preamp and a big volume knob, in the smallest box here.
The JFET instrument input is voiced like a valve amp input, so a direct guitar track sounds warmer than a plain DI.
Strengths
- The single Class A console mic preamp is the same circuit family Audient uses in its large consoles.
- The JFET instrument input is voiced for guitar and bass, so direct guitar tracks sound less flat.
- Two headphone outputs, in 6.35 mm and 3.5 mm, mean no adapter hunting.
Limitations
- Only one microphone input, so a duo or a stereo mic pair is out.
- Maximum sample rate is 96 kHz, while most rivals here reach 192 kHz.
- One shared volume knob controls both headphones and speakers, which takes getting used to.
What owners report
Commonly praised
- The console-grade mic preamp gives a single voice a clean and full sound
- the JFET guitar input makes direct guitar tracks sound warmer than a plain DI
- two headphone sockets in different sizes mean no adapter hunting
Common complaints
- Only one microphone input, so a duo or stereo pair is out
- the 96 kHz ceiling is lower than most rivals here
- one shared knob for headphones and speakers takes getting used to

| Headphones | Dual outputs, 6.35 mm and 3.5 mm |
| Control | ScrollControl knob doubles as a DAW control |
| Connection | USB-C, bus powered |
Best for: Guitarists and vocalists who record one source at a time and care most about the mic preamp.
Skip if: You need two microphones at once, or you record at sample rates above 96 kHz.
Best for careful takes
MOTU M2 USB-C Audio Interface, 2-Input (Interface Only)
The metering pick: a colour LCD that shows exactly what each input is doing.
The LCD meters show both inputs at once, so a singer-guitarist can see a clipping guitar string before it ruins a vocal take.
Strengths
- The full-colour LCD shows level meters for every input and output, so clipping is visible before it is audible.
- ESS Sabre32 converters give the outputs a measured 120 dB of dynamic range.
- Latency is very low with the MOTU drivers, which matters when monitoring through the computer.
Limitations
- No Auto Gain or clip protection, so levels need watching.
- The software bundle is generous but takes time to install and sort through.
- Two inputs only, with no ADAT or other expansion.
What owners report
Commonly praised
- The colour LCD shows every input and output level at a glance, so clipping is seen before it is heard
- converters give playback a clean and detailed sound
- latency stays low enough to monitor through the computer comfortably
Common complaints
- No Auto Gain, so beginners must learn gain staging on their own
- the software bundle is generous but takes a while to install and sort through
- two inputs with no way to expand later

| Metering | Full-colour LCD for all inputs and outputs |
| MIDI | MIDI in and out |
| Connection | USB-C, bus powered |
Best for: Recordists who set levels by eye as well as by ear, and who want very low latency.
Skip if: You want Auto Gain, or you need more than two inputs.
Best warm two-input
Universal Audio Volt 2 USB Audio Interface, 2-Input (Interface Only)
A vintage-flavoured two-input box with a simple, honest layout.
Vintage mode on both channels warms voice and guitar together, without the 276's compressor premium.
Strengths
- Vintage mode gives each preamp a warmer, tube-flavoured character at the press of a button.
- Two XLR combo inputs with individual gain knobs make a voice-and-guitar session quick to set up.
- MIDI in and out is included, which the Scarlett 2i2 does not offer.
Limitations
- No Auto Gain or clip protection, so setting levels is on you.
- Two inputs only, with no path to expand later.
- The bundled software needs registering and downloading before first use.
What owners report
Commonly praised
- Vintage mode gives voice and guitar a warmer character without any plugin
- two combo inputs with separate gain knobs set up fast
- MIDI in and out is included where some rivals leave it out
Common complaints
- No Auto Gain means levels must be set by hand and watched
- no clip protection for sudden loud peaks
- the bundled software needs registering and downloading before first use

Best for: Singer-songwriters who want a warmer preamp sound without plugins or extra gear.
Skip if: You need four inputs, or you prefer a completely clean and neutral preamp.
Best for guitar effects
Steinberg UR22C USB 3.0 Audio Interface, 2-Input (Interface Only)
Onboard effects and loopback, for streamers as well as recordists.
Onboard DSP puts reverb and amp simulation on the monitoring mix, so a guitarist hears a finished sound while tracking dry.
Strengths
- Onboard DSP runs reverb and channel-strip effects while you monitor, with no delay and no computer load.
- The loopback function mixes your mic with computer audio for streaming without extra routing software.
- 32-bit conversion gives the most headroom of any interface in this guide.
Limitations
- The DSP effects are basic next to full plugins, and only affect monitoring unless you print them.
- Cubase AI is included, but the full Cubase experience costs extra.
- Two inputs only, and the metal case is heavier than the plastic rivals.
What owners report
Commonly praised
- Onboard DSP effects let you hear reverb while tracking with no delay
- loopback mixes mic and computer audio for streaming without extra software
- 32-bit conversion gives generous headroom against clipping
Common complaints

Best budget duo
PreSonus Studio 24c USB-C Audio Interface, 2-Input (Interface Only)
The budget two-input pick, with a full DAW in the box.
Two inputs, MIDI, and Studio One Artist for the least money. The no-frills way to record voice and guitar together.
Strengths
- Studio One Artist recording software is included, so the interface arrives with a real DAW rather than a trial.
- Two XMAX-L mic preamps with a clear level meter strip on the front panel.
- MIDI in and out is included at a price where many rivals leave it out.
Limitations
- No Auto Gain or clip protection, so beginners must learn to set levels by hand.

Best for one at a time
Focusrite Scarlett Solo 4th Gen, 2-Input USB Audio Interface (Interface Only)
One mic and one guitar, with the level-setting done for you.
One mic and one guitar input, recorded separately. The cheapest path if you never play and sing at the same moment.
Strengths
- Auto Gain sets the recording level for you, which removes the most common beginner mistake.
- One proper mic preamp plus a separate Hi-Z instrument input covers a voice and a guitar without swapping cables.
- Air mode adds a brighter, more open character to vocals and acoustic instruments when you want it.
Limitations
- Only one microphone input, so two-person recording is not possible.

Questions, answered
Should I record guitar and vocals together or separately?
Separately gives a cleaner mix, because the mic does not pick up the guitar and the guitar input does not pick up the voice. Together gives a better performance, because you play naturally. Record together when the feel matters, separately when the mix matters. A two-input interface supports both; a one-mic interface only supports separately.
Do I need a DI box with these interfaces?
No. Every interface here has a Hi-Z instrument input that accepts a guitar or bass directly. A separate DI box only helps if you want to split the signal to an amp and the interface at the same time, or if you are running a very long cable.
What is Air mode, and should I use it?
Air mode is Focusrite's gentle high-frequency lift on the preamp, modelled on its ISA console range. It suits vocals and acoustic guitar that sound dull or muffled. Try it on and off during a test take and keep the one that sounds better; it is a taste choice, not a rule.
