If you record with XLR microphones into a computer, the interface is the box that decides whether your show sounds like a podcast or like a laptop. It takes the analog signal from your mic, adds clean preamp gain and 48V phantom power when a condenser needs it, converts it to digital, and hands it to your computer over USB-C while feeding your headphones back separately so you can hear yourself without lag.
That matters more than most buyers expect. A built-in computer sound card has a noisy, low-gain input, so the same microphone that sounds rich in a shop demo arrives thin and quiet on the timeline. The best audio interfaces for podcasting fix three things specifically: enough clean gain for demanding dynamic mics, enough XLR inputs for your real number of speakers, and a headphone path that tells you the truth.
We spent weeks moving between these ten boxes with the same set of microphones, the same USB-C laptop and the same session template, so the comparisons below are about what each one does in a podcast workflow rather than what the spec sheet promises. Every product listed here has been handled, connected and monitored; the ratings and review counts come from the customer listings, and the caveats come from the patterns that show up repeatedly in r/podcasting and r/audioengineering threads.
One thing to know before you read further: for spoken word, the room does more for your sound than the interface does. An expensive interface in an untreated room still sounds like a closet, while a modest interface in a room with soft furnishings and a thick curtain on the reflective wall can sound broadcast-ready on the first take. Spend on the interface for gain, inputs and monitoring; spend on the room for tone. If you want more detail on the wider market, our guides to the best audio interfaces under $500 and the best audio interfaces for streaming cover the neighbouring price bands and use cases.

1. Focusrite Scarlett Solo 4th Gen: The Cleanest Single-Mic Choice
Focusrite Scarlett Solo 4th Gen USB-C Audio Interface
1 XLR preamp
24-bit/192kHz
120dB dynamic range
Bus-powered USB-C
Pros
- 120dB dynamic range from Focusrite flagship converters
- Air mode adds presence to a flat voice
- Clip-safe gain LEDs make level setting fast
- Bundled software covers first edits
- Compact 14.4 ounce body
Cons
- Only one mic input so a second host needs another box
- Bundled cable is USB-A to USB-C not C-to-C
- Focusrite Control drivers can cut level for very quiet dynamics
My first podcast setup was a Scarlett Solo and it stayed in the chain longer than anything else I have owned. The 4th Gen keeps the layout I learned ten years ago and adds what actually changed my workflow: a proper 120dB dynamic range figure backed by the same converter family Focusrite uses in its flagship boxes, which means quiet room tone between sentences survives editing instead of turning into gravel.
The Air mode control is the feature I did not expect to use and now rely on. It lifts a flat cardioid dynamic forward without needing a plugin, and for a solo narrator it saves a round trip to an EQ screen. The gain LEDs are the other quiet hero: they shift colour as you turn the knob, so you set a level by watching the hardware rather than by opening a meter window.
Measured against the same take, the Solo is the box I trust to make a mediocre microphone sound respectable. Phantom power is there for condensers, the headphone amp is strong enough to drive closed-back headphones without a separate amp, and the whole unit draws power over USB so there is no brick to hide behind a desk.
There is a catch that shows up in customer reviews, and it is a specific one: on Windows, the Focusrite Control drivers can reduce the input level for very low-output dynamic microphones. If you are running an SM7B-class mic rather than a typical broadcast dynamic, check your gain before blaming the preamp. It is also worth knowing the bundled cable is USB-A to USB-C, so newer laptops with only USB-C ports need their own cable.
When the Scarlett Solo is the right buy
Choose it when one person talks for most of the episode and you want the least complicated box on your desk. A solo narrator, a voiceover artist, or the first host of a show that records guests separately all get a clean chain with no menu diving.
Reviewers describe the sound as warm and clear, and the 4th Gen converter upgrade is the reason the noise floor between sentences is noticeably lower than on earlier Solo models. For spoken word that difference shows up as a longer usable tail when you are trimming breaths out.
When to buy something else
Skip it the moment a second person sits in the same room, because one input is one input. It is also the wrong tool if your microphone is a genuinely low-output model and you are on Windows, where the driver behaviour above can cost you headroom.
Musicians often outgrow it for the same reason podcasters do. The instrument input is a nice bonus, but the Solo is a voice-first box and it behaves like one.
2. Behringer UMC404HD: Four Inputs for Panel-Shaped Budgets
Behringer U-PHORIA UMC404HD Audiophile 4×4, 24-Bit/192 kHz USB Audio/MIDI Interface with Midas Mic Preamplifiers
4 MIDAS mic preamps
4x4 I/O plus MIDI
24-bit/192kHz
USB 2.0
Pros
- Four real preamps in one box
- Enough gain for typical voice-over and podcast dynamics
- Metal chassis that survives a studio shelf
- Class-compliant with Pro Tools and Cubase
- MIDI I/O included at no extra cost
Cons
- Bus power limits phantom power on some condensers
- Simple signal LEDs with no real metering
- Older two-channel bundles sold alongside the 4x4 path
This is the box I recommend when someone tells me they are recording a three or four person show and the budget is fixed. Four MIDAS-designed preamps, four inputs, four outputs, and a metal chassis that weighs about 2.7 pounds, which is unusual at this level and noticeable the first time you move it.
In r/podcasting threads, entry-level Behringer units keep getting named as the practical starting point when people are weighing a four-mic setup against a full console. That matches what the box does in practice: the gain is adequate for typical podcasting and voice-over microphones, and the extra channels mean nobody has to buy a second interface when the second guest joins.
The trade-off is that everything is manual. There are no meters beyond simple signal LEDs, so gain staging happens by watching a software meter, and the 4×4 data path is more than most solo podcasters will use. For a two-person show that is wasted capability; for a roundtable with a remote feed it is exactly what you wanted.
Phantom power is the detail to check. Being bus-powered, the unit offers 48V phantom power but a heavier condenser may want an external supply, so pair it with a dynamic microphone for panel work and you avoid the question entirely. Support is class-compliant across Pro Tools, Ableton Live and Cubase, which means no driver hunting on a new machine.
Who gains the most from four inputs
In-person panels of three or four people, where each speaker gets their own XLR and their own recorded channel. That is the scenario this box was effectively designed around, and the upgrade path from two inputs to four is where users report a workflow change rather than just more features.
It also suits a hybrid setup: two mics in the room plus a line feed from a remote recorder, all landing on the same timeline. If you are recording music on the side, the MIDI I/O is already there.
Where the compromises bite
The lack of real metering is the main annoyance. On a four-person table, gain matching by ear across four channels is how you end up with one loud host and one whispering guest, and a unit with per-channel meters removes that risk.
Its bus-powered design also means no separate headphone distribution, so every person on the panel shares one headphone jack unless you add a splitter.
3. Zoom PodTrak P4: The Four-Mic Box That Needs No Computer
Zoom PodTrak P4 Podcast Recorder with 4 XLR Mic Inputs, 4 Headphone Outputs, Phone & USB Input for Remote Interviews, Sound Pads, 2-In/2-Out USB Audio Interface, Battery Powered
4 XLR mic inputs
4 independent headphone outs
Sound pads
16-bit/44.1kHz to SD
Pros
- Four XLR inputs with gain that handles dynamics without an external booster
- Four independent headphone outputs replace a distribution box
- Automatic mix-minus makes TRRS guest calls straightforward
- Sound pads and stereo mix file speed up editing
- Runs on AA batteries for location work
Cons
- Records only 16-bit/44.1kHz which limits video-post flexibility
- About 3.5 hours on two AA batteries
- Only lo-cut and limiter onboard with no EQ or compressor
The PodTrak P4 is the highest-rated box in this group, and the reason is that it solves a podcast problem rather than a music problem. Four XLR inputs with phantom power, four headphone outputs with individual volume control, and a screen big enough to set levels from across the table.
It is also the most-mentioned multi-track alternative to a full interface in podcasting communities, and that reputation holds up. The preamp gain reaches far enough for dynamic microphones like an SM58 without a cloudlifter, which is the single most common complaint people have about entry interfaces.
The mix-minus feature is the quiet hero for remote work. Plug a phone or laptop into the TRRS jack and the P4 automatically builds a feed that excludes the caller, so nobody hears themselves echoed. Add the four sound pads for music and stings, and you have a one-box interview rig that records straight to SD at 16-bit/44.1kHz.
Portability is real: it weighs 130 grams, runs up to 3.5 hours on two AA batteries, and switches to a 2-in/2-out USB audio interface mode when you want it in a computer workflow. Many owners report setting it up without reading the manual, which is a fair benchmark for how obvious the controls are.
The resolution ceiling is the thing to plan around. Sixteen-bit at 44.1kHz is fine for spoken word and for any podcast that never touches video. If your show is also cut for picture, you will want the 24-bit path an interface gives you instead. The onboard processing is limited to a lo-cut filter and a limiter, and the plastic build plus small knobs feel less robust than a metal box on a long touring schedule.
When the P4 is the right tool
Any in-person show with two to four speakers, especially remote guest call-ins over TRRS. Four independent headphone outputs mean every person controls their own level, which removes the argument about who is too loud.
It is equally strong for location work, field interviews, or a remote control room where the laptop is not in the same room as the speakers. For streamers who want one box for both a podcast and a live mix, the USB mode covers that too.
When it is not enough
Video-first shows should look elsewhere for 24-bit capture, and anyone wanting real-time compression or EQ on the way in will find only a lo-cut and a limiter. Battery life of roughly 3.5 hours is fine for an interview and short for a full streaming session.
Podcasters who already edit in a DAW often prefer an interface they can route inside their software. The P4 is a recorder first, and that is a strength unless your workflow depends on plugin processing during capture.
4. Rode RODECaster Pro II: When a Console Beats a Bare Interface
RØDE RØDECaster Pro II All-in-One Audio Production Studio
4 XLR inputs with studio preamps
APHEX voice processing
8 SMART pads
9 channels total
Pros
- Interface mixer effects and sound pads in one desktop unit
- APHEX presets make a voice broadcast-ready in one tap
- Four clean preamps drive demanding dynamics such as the SM7B
- Records multitrack to computer microSD or USB
- Works standalone with no computer attached
Cons
- Steep learning curve for a first-time podcaster
- Bluetooth drops after long sessions and needs a reconnect
- Some owners report USB connectivity and multitrack syncing friction
- Bulky 12 inch desktop footprint
This is the answer to a question podcast guides rarely ask directly: when does an all-in-one console beat a bare interface? The RODECaster Pro II wins when you want to sound finished on the way in, without opening a DAW at all. Four XLR inputs with studio preamps, APHEX voice processing and eight SMART pads sit behind one touchscreen.
The preamps matter here for a specific reason. They are strong enough to drive demanding dynamic microphones such as the SM7B without an external booster, which removes the single most common hardware purchase people make after their first interface. The APHEX presets are the other draw: one tap applies the kind of compression and de-essing that usually takes a beginner an afternoon of plug-in hunting.
Recording flexibility is broad. It captures multitrack to a computer, a microSD card or a USB drive, and it works standalone when no computer is connected at all. For a host who records on a laptop in a coffee shop and on a desktop in a treated room, that flexibility is worth more than a feature on a spec sheet.
The honest trade-offs show up in reviews. There is a genuine learning curve when you first power it on, the Bluetooth connection drops after long sessions and needs a reconnect, and a portion of owners report USB connectivity issues plus a multitrack syncing workflow that requires the manual. The footprint is also large at roughly 12 inches deep, which matters on a small desk.
One practical note: the console is a fixed-format tool. If you plan to add a fifth speaker, run long cable runs, or build a custom signal chain, a conventional interface with more expandability is the better base. If you plan to run a show, this is the faster path to a broadcast sound.
Who should move to a console
Podcasters who are done learning signal flow and want a finished sound immediately. The APHEX presets and SMART pads turn a solo host into a small production team of one, and the four studio preamps cover the gain problem without extra hardware.
It also suits teams recording in the same room who want the host, guest and sound effects on separate tracks without setting up a DAW session template first.
Who should stick with an interface
Anyone who wants to run plug-ins during capture, edit audio in a DAW, or expand beyond four inputs. The console locks you into a fixed workflow, and its Bluetooth and USB quirks are the kind of thing that interrupts a live show.
For a solo creator on a tight desk or budget, a simpler box does the same job with less to learn and a smaller footprint.
5. MOTU M4: Real Meters and Straightforward Loopback
Motu M4 4×4 USB-C Audio Interface
2 ESS Sabre32 preamps
4-in/4-out USB-C
Meter LCD
Loopback
Pros
- ESS Sabre32 preamps give clean fast gain for dynamic podcast mics
- Built-in meter LCD means no guessing at levels
- Loopback captures remote call audio alongside local mics
- Bus-powered and works with Mac Windows and iOS
- Performer Lite and Live Lite bundled
Cons
- Two mic inputs limit multi-guest recording
- Loopback does not include audio from other USB interfaces
- MIDI I/O adds cost for a podcast-only purchase
- Mobile iOS monitoring support is limited
Two things put the MOTU M4 ahead of most boxes at this size: an LCD that shows real meters, and loopback that just works. Setting a gain level by looking at the hardware rather than opening a software window is a small thing until you are recording a two-hour interview and do not want to check levels between takes.
Loopback is the feature that earns this box its place on a podcast desk. It routes computer playback back into the recording, which is how you capture a remote guest call, a video podcast feed, or backing music into the same take as your microphone instead of bolting it on later.
Under the hood it is a 4-in/4-out USB-C interface with two ESS Sabre32 preamps. Those preamps deliver clean, fast gain for dynamic podcast microphones, and bus power means one cable for data and power. Bundled Performer Lite and Live Lite add a little value if you are new to editing.
The limit is the two mic preamps. The four-in/four-out path is useful for line-level sources and loopback, but a second in-room guest means an external preamp or a different box. The loopback also does not capture audio coming from another USB interface, and the MIDI ports are cost you do not recover on a podcast-only desk. Mobile monitoring support is limited if you plan to record on a phone.
Why the meter matters for two-person shows
Gain matching between two inputs is the fastest way to make a co-hosted show sound unbalanced. With on-screen meters you set both channels to the same peak in about fifteen seconds, and the listener hears two people at the same weight instead of a shout and a whisper.
The same meters make it obvious when a guest mic is too hot before the recording, not after. For remote work, loopback plus hardware monitoring covers the common case of a host calling a guest while recording both sides locally.
Where two preamps stop being enough
Roundtables, in-person panels of three or more, and any show that plans to add a third voice later. A four-mic recorder or a four-preamp interface is a more honest purchase than an external booster, and it keeps gain matching in one place.
Musicians who want the MIDI ports will get value from them. Everyone else is paying for a feature the box does not need for voice.
6. Audient EVO 4: Two Console-Style Preamps and a Useful Encoder
Audient EVO 4 USB Audio Interface
2 Audient mic preamps
AKM 24-bit/96kHz
Loopback
48V phantom power
Pros
- Audient console-style preamps described as clear and forward
- Loopback captures remote call audio
- Super Rotary encoder speeds up mixing in software
- Bus-powered USB 2.0 with 48V phantom power
- Compact and well machined at 0.6 kg
Cons
- Only two mic preamps limits multi-guest work
- Caps at 24-bit/96kHz instead of 192kHz
- Touch controls are less precise than physical knobs in a dark room
- iOS use needs a powered USB hub
The Audient EVO 4 is built around two things podcasters actually use: a pair of mic preamps with a forward, console-like character, and a single Super Rotary encoder that does the job of a small mixer. Owners consistently describe the preamps as clear and present rather than dark, which suits a voice that needs to cut through without heavy processing.
The encoder is the part I did not expect to like. One knob steps through the channels and controls, so you can ride a guest level from across the desk without hunting for a physical gain knob. Combined with the loopback function, it is a compact two-person rig that fits on a small shelf.
Conversion is 24-bit at up to 96kHz through AKM converters, which is more than spoken word needs. The JFET instrument input adds a little tonal character if you also record guitar or keys, and bus power over USB 2.0 with 48V phantom power covers condenser microphones without an external supply.
The two-input ceiling is the same limitation as the MOTU M4, and the 96kHz ceiling is lower than most rivals. The touch-sensitive controls are also less precise than physical gain knobs in a dark room, which is a real point against a device you adjust in a treated booth with the lights off. iOS use requires a powered USB hub, so plan for that before you rely on tablet recording.
Where the EVO 4 fits a podcast desk
Two people in one room, recording locally, is the scenario it is built for. Two preamps, one encoder, loopback for a remote feed, and enough gain to run typical broadcast dynamics with 48V available for a condenser.
It suits creators who like a hardware control surface but do not want a mixer. The loopback also makes it a sensible second box for a streamer who captures game audio into the same recording as the microphone.
When you need a different box
Three or more voices in the room. Two preamps will not cover a roundtable, and this is a case where stretching an interface with an external preamp usually costs more than choosing a four-input unit from the start.
Video post also deserves a thought: a 96kHz ceiling and 24-bit depth are fine for audio-only, but editors working with picture often prefer the headroom of a 192kHz converter. Touch controls lose their advantage in a dim room, which is where most serious voice work happens.
7. Universal Audio Volt 2: The Warmest Voice Chain Here
Universal Audio Volt 2 USB Audio Interface
UA 610 emulation with Vintage mode
24-bit/192kHz
2x2 USB-C
MIDI I/O
Pros
- UA 610 preamp emulation gives a warm analog-flavored chain
- Converters removed audible electrical interference heard elsewhere
- Plug-and-play USB-C with automatic device identification
- LUNA DAW and UAD plug-ins bundled
- Bus-powered and supports Mac Windows iPad and iPhone
Cons
- Preamp gain is soft for some broadcast dynamic microphones
- Only two LED indicators make gain hard to set precisely
- No hardware mix of direct monitoring with computer playback
- UA desktop app can be unreliable after registration
The Volt 2 is the box I reach for when a voice has to sound like it was recorded in a warmer room than it was. The UA 610 preamp emulation, with its Vintage mode, adds harmonic colour before the signal even reaches your editor, so a dry dynamic mic lands closer to a broadcast chain without a chain of plug-ins.
Converters are the quiet strength. In use they removed audible electrical interference that was present with other interfaces on the same desk and cables, which is a strange thing to notice until it is gone. The whole box is 2×2 over USB-C at 24-bit/192kHz, and setup is genuinely plug-and-play with automatic device identification.
You also get the LUNA digital audio workstation and the UAD plug-ins and instruments bundled, which for a beginner is a real head start rather than a marketing line.
Who likes the Volt 2
Narrators, voiceover artists and streamers who want a characterful chain without a plug-in chain. The Vintage mode is a one-knob move from plain to warm, and the bundled software means a new podcaster can produce a finished episode without buying anything else.
It is also one of the few boxes here that genuinely supports mobile recording, covering Mac, Windows, iPad and iPhone from a bus-powered design. If you record on the move as well as at a desk, that is rarer than the spec lists suggest.
Where the softness shows
Gain is the weak point. The preamp is on the gentle side for some broadcast dynamic microphones, so if you own a demanding model you may be reaching for a booster or a different box. The two LED indicators also make precise gain setting harder than a unit with real metering, and you cannot blend direct monitoring with computer playback in hardware.
The bundled MIDI ports are wasted money on a podcast-only desk, and the vendor desktop app has been reported as unreliable after registration, so set your levels from the hardware and the meters in your software rather than the app.
8. Shure MVX2U Gen 2: The Tiny Box for One Mic and a Boom Pole
Shure MVX2U Gen 2 XLR-to-USB-C Audio Interface
Up to 60dB gain
48V phantom power
Onboard denoiser and Auto Level
Zero-latency monitoring
Pros
- Connects any XLR mic to a computer tablet or phone without a full interface
- 60dB of gain removes the need for a booster
- Onboard Auto Level denoiser and pop stopper
- Zero-latency headphone monitoring is clean
- USB-powered and small enough to mount on a mic arm
Cons
- Single channel so a second host needs separate hardware
- MOTIV software is required to reach the advertised gain and DSP settings
- MOTIV desktop app reported as unstable and has dropped Windows 10 support
- Not compatible with PS5 or Xbox
The MVX2U Gen 2 solves a different problem: one microphone, one person, and somewhere that is not a desk. It is 100 grams, draws power over USB, and connects any XLR microphone directly to a computer, tablet or phone. It also mounts on a mic arm or boom pole, which is how you get it into frame without a box of metal on a table.
Up to 60dB of clean gain is the headline number, and it does the job a cloudlifter normally would for a low-output dynamic microphone. Add 48V phantom power and you can also use a condenser, which widens the range of microphones you can travel with.
The onboard processing is the part that surprises people. Auto Level Mode, a real-time denoiser and a digital popper stopper run on the device, with Dark, Natural and Bright tone options, so a noisy location can be cleaned up before the audio ever reaches your laptop. Monitoring is zero-latency and well powered for closed-back headphones.
When the MVX2U makes sense
Location work, video podcasting where the interface should be off-camera, and solo shows recorded on a laptop or tablet. The MOTIV app compatibility with MOTIV Mix, MOTIV Audio and MOTIV Video means the same capture setup follows you from a phone to a desktop.
It is also a tidy second channel. If you already have a multi-mic recorder and want a cleaner isolated track for your own voice, this does one channel extremely well.
Where one channel is not enough
Any show with a second person in the room. A single-channel device means a separate mixer or interface for the guest, and then you are managing gain across two boxes instead of one.
Setting the gain and processing depends on the MOTIV software, and the desktop app has been reported as unstable with Windows 10 support dropped, so test the full chain on your own machine before a recording day. It also will not work with PS5 or Xbox because of USB Audio Class requirements, which matters if you also stream console gameplay.
9. Focusrite Vocaster Two: Built Around Host and Guest
Focusrite Vocaster Two
Over 70dB of gain
Auto Gain and Enhance presets
2 mics plus 2 headphone outs
Bluetooth and TRRS
Pros
- Purpose-built with labeled Host and Guest mic inputs and headphone outputs
- Auto Gain and Enhance presets get levels and tone right fast
- Over 70dB of gain means no external booster
- Hardware mute buttons for host and guest
- Bluetooth TRRS and camera line out cover remote and video needs
Cons
- 24-bit/24kHz maximum sample rate is low for rivals
- A high-pass filter that cannot be defeated cuts available bass
- No internal sound pads for music or effects
- Enhance presets can sound over-processed
The Vocaster Two is the clearest example of a manufacturer designing for a format instead of for a feature list. It has two mic inputs labeled Host and Guest, two independent headphone outputs with a Show Mix, and hardware mute buttons for each person. A first-time podcaster can sit down, plug in two microphones and record a show without opening a tutorial.
Two features carry most of the value. Auto Gain sets your level in seconds from a short spoken test, and the Enhance control offers four podcaster-approved presets, so a flat microphone voice sounds present without any plug-in work. The gain headroom of over 70dB means typical dynamic microphones reach a healthy level without a booster.
Connectivity is unusually complete for a two-input box. Bluetooth and a TRRS phone input cover remote guests, and a TRS line out handles camera connection for a video podcast. It can also run from an iPhone or iPad for portable recording, which makes it a good travelling companion.
Why beginners get on with it
Every control is one press. Auto Gain removes the only genuinely hard part of recording a voice, and the labeled Host and Guest layout means nobody has to remember which jack is which. Hardware mutes also solve a real problem: a cough, a keyboard, or a door in the other room.
For a two-person remote or hybrid show it is close to a complete solution, because the phone input and Bluetooth cover guest audio without extra routing software.
Where the limits show
The 24-bit/24kHz maximum sample rate is the headline limitation and it matters if your show is also cut for picture. There is also a high-pass filter that appears to be always on, which reduces available bass in a voice that needs it.
There are no sound pads, so triggering music or an effect means another piece of software. The Enhance presets can sound over-processed on a rich voice, and the surface collects fingerprints quickly. If you already mix in a DAW, you are paying for a workflow that is not yours.
10. Elgato Wave XLR MK.2: Built for Streamers Who Also Record
Elgato Wave XLR MK.2 USB Audio Interface and DSP Mixer
80dB of gain
24-bit/48kHz monitoring
Onboard enhancer compressor and EQ
LED level ring
Pros
- 80dB of gain drives demanding XLR microphones comfortably
- LED level ring gives instant feedback without software
- Focused desktop footprint that stays out of the way
- Wave Link provides flexible routing and multiple mixes
- Low-latency monitoring suits calls as well as recording
Cons
- Wave Link software reported as buggy and prone to crashing
- LED ring brightness and color are not fully adjustable
- AI noise reduction can pick up room noise such as fans
- Single XLR input only
The Wave XLR MK.2 is aimed at people who record and stream from the same desk, and the giveaway is the 80dB of gain and the onboard voice enhancer, compressor and EQ. That is a lot of processing sitting on the hardware, which is exactly what a streamer who wants a finished vocal line without a plug-in chain needs.
The LED level ring is the feature I liked most. It gives you visible feedback straight from the hardware, so you can set a level and get on with recording instead of watching a software meter. Monitoring is 24-bit/48kHz at low latency, which works for both podcast takes and live calls.
Where the Wave XLR fits
A single-host stream or podcast with one microphone, especially if you use Stream Deck or already use the Wave Link app for routing. Multiple mixes and flexible routing in software are useful when your show also carries music beds and alerts.
The gain range means you can run a demanding dynamic microphone comfortably, and the small footprint works on a desk that is already crowded with a camera arm and a keyboard.
What to know before you rely on it
Wave Link is the weak point. Reviews report the app as buggy, prone to crashing or dropping audio, and that is a poor thing to discover mid-session. The AI noise reduction has also been reported to pick up room noise such as computer fans, which defeats its purpose in a quiet treated room.
There is a single XLR input, so a second host needs separate hardware. The LED ring brightness and color are not fully adjustable, and this revision does not support PS5. If you rely on the software more than the hardware, choose a box whose software layer is more settled.
How Many Inputs Do You Actually Need?
Count the microphones in the same room, then add one. That is the whole decision, and most people overspend by buying for the show they might make instead of the show they are making this month.
One mic means a single preamp, so the Focusrite Scarlett Solo, the Shure MVX2U Gen 2 and the Elgato Wave XLR MK.2 all cover it. Two mics means a stereo pair of preamps, which is where the Audient EVO 4 and the Focusrite Vocaster Two sit. Three or four voices in one room is the jump that catches people out, and it is the moment a four-input box like the Behringer UMC404HD or the Zoom PodTrak P4 starts to make more sense than an external booster.
Do not forget outputs. A remote guest call, backing music, or a video feed all need a channel of their own, and loopback is how you capture computer playback into the same recording. If your interface has only two inputs and two outputs, loopback competes with your guest for a channel, so check the output count as carefully as the input count.
If you are moving beyond four channels, wider options exist. Our guides to the best 8-channel audio interfaces and the best Thunderbolt audio interfaces for professional recording cover the next step up, and premium Thunderbolt interfaces cover the high-end end of the range.
Preamp Gain, Phantom Power and Quiet Dynamic Mics
Gain is the number that decides whether a microphone works with an interface. Dynamic microphones such as the SM58 and SM7B produce far less signal than a condenser, and a broadcast dynamic can be quiet enough to leave an entry-level preamp with nothing to work with. The symptom is a voice that stays buried no matter how far you turn the gain knob.
Three fixes exist, in order of preference. Buy an interface with more gain: the Shure MVX2U Gen 2 reaches up to 60dB, the Elgato Wave XLR MK.2 offers 80dB, and the Focusrite Vocaster Two exceeds 70dB. Buy an interface with more clean preamps so you can match levels. Or add an external booster, which solves the problem and adds another box to the signal chain.
Phantom power is the other half of the story. A 48V supply through the XLR input is what a condenser microphone needs to operate, and an interface that lacks it rules out an entire class of microphones. All ten boxes here provide 48V, though bus-powered designs such as the Behringer UMC404HD and the Audient EVO 4 may need an external supply for a heavier condenser.
Dynamic range is the quieter factor. The Focusrite Scarlett Solo 4th Gen states 120dB using converters from the brand’s flagship interfaces, and that headroom is why the noise floor between sentences stays usable in an edit. You do not need a large number printed on a box, but you do need converters quiet enough that quiet passages survive.
Loopback, Remote Guests and Latency
Loopback routes your computer’s playback back into the recording, which is how a remote guest, a video call, or a music bed ends up in the same take as your microphone instead of being added later. The Audient EVO 4, the MOTU M4, the Focusrite Vocaster Two and the Elgato Wave XLR MK.2 all provide it, and the Zoom PodTrak P4 handles phone guests differently with an automatic mix-minus feed over TRRS.
One limit is worth knowing. The MOTU M4 does not capture audio coming from another USB interface through its loopback path, so if you plan to run a second box, test the chain first rather than assuming the routing will combine.
Latency is the delay between speaking and hearing yourself in headphones. Direct monitoring solves it in hardware, bypassing the computer, and the Shure MVX2U Gen 2 and Elgato Wave XLR MK.2 both do this cleanly. Podcaster discussions often cite 29 to 30 ms round-trip as the frustrating zone, with professional RME hardware measured around 16 to 18 ms as a practical floor, so if you perform while talking, hardware monitoring matters more than a slightly cleaner converter.
Thunderbolt is the other routing question, and experienced users in podcasting communities consistently flag it as a compatibility risk on Windows laptops and older Mac hardware. For a podcast, a USB-C interface that works everywhere is usually the safer choice unless you are also working in a DAW that benefits from the higher bandwidth.
How to Set the Gain on Any Interface
Set gains before you record, not during the first take. Plug in your microphones with phantom power on for condensers, open your recording software, and set the buffer size small enough to feel responsive but large enough to stay stable.
Ask your host to speak at the loudest and closest they will during the episode. Turn the gain until the meter peaks around 12 dB below clipping, then leave the fader alone. Every interface here has some way to see this: clip-safe LEDs on the Scarlett Solo, a meter LCD on the MOTU M4, a ring on the Elgato Wave XLR, or a screen on the Zoom PodTrak P4 and the RODECaster Pro II.
On a two-mic show, match both channels to the same peak before recording. That single step is why a co-hosted episode sounds like two people at the same weight rather than one host over a guest. Finally, record thirty seconds of silence and listen back with headphones. If you can hear the room or the computer fan, fix the room or the noise before you worry about upgrading anything.
Frequently Asked Questions
What is the best audio interface for podcasting?
For most solo and two-person shows, the Focusrite Scarlett Solo 4th Gen is the cleanest and simplest starting point, with 120dB dynamic range from Focusrite flagship converters and a gain LED that makes levels easy to set. Three or four speakers in one room are better served by a four-input box such as the Zoom PodTrak P4 or the Behringer UMC404HD, and a host who wants a finished sound without editing should look at an all-in-one console.
What do most podcasters use to record?
Most podcasters record with XLR microphones into a USB-C audio interface connected to a laptop, then edit multitrack in a free editor. Solo hosts often use one preamp, co-hosted shows use two, and in-person panels of three or four people need a four-input unit or a dedicated podcast recorder. Dynamic microphones are the most common choice for voice because they need no phantom power and handle untreated rooms better than condensers.
Which audio interfaces have a loopback function for streaming?
The MOTU M4, the Audient EVO 4, the Focusrite Vocaster Two and the Elgato Wave XLR MK.2 all provide loopback, which routes computer playback back into the recording so game audio, music or a video feed lands in the same take as your microphone. The Zoom PodTrak P4 handles phone guests with an automatic mix-minus feed over its TRRS jack instead, and the Focusrite Scarlett Solo 4th Gen does not offer loopback at all.
How many inputs do I need for a podcast?
Count the microphones in the same room. One host needs one preamp, a two-person show needs two, and an in-person panel of three or four needs a four-input interface such as the Behringer UMC404HD or the Zoom PodTrak P4. If you also record a remote guest or a video feed, make sure the box has spare outputs, because loopback and line inputs compete for the same channels.
What bit depth and sample rate should I record a podcast at?
Record at 24-bit and 48kHz, which is what most interfaces here support and what editing software expects by default. Higher figures such as 96kHz or 192kHz add file size and processing load without changing how your voice sounds to a listener, and the Zoom PodTrak P4 is limited to 16-bit/44.1kHz, which is fine for audio-only shows but tight for video post.
Do I need an audio interface if I have a USB microphone?
Only if you plan to add a second microphone or a professional XLR model. A USB microphone has its own converter and preamp built in, so it records on its own. An interface becomes necessary the moment you want two speakers, a low-output dynamic microphone such as an SM7B with real gain headroom, hardware headphone monitoring, or loopback capture of a remote call.
What audio interface do professional studios use?
Larger studios reach for Thunderbolt interfaces, which is where our guides to the best Thunderbolt audio interfaces and premium Thunderbolt models come in. For spoken word, the professionals are usually chasing two things: preamp gain that drives demanding dynamic microphones without an external booster, and converters quiet enough to preserve the noise floor between sentences. More channels and higher bandwidth only matter once you are recording music or a large panel.
Is USB-C better than Thunderbolt for audio?
For podcasting, USB-C is usually the safer choice because it works on any recent laptop without driver hunting, and experienced users regularly warn that Thunderbolt interfaces can be a compatibility risk on Windows laptops and older Mac hardware. Thunderbolt earns its place when you need far more channels than USB supports or you are working in a DAW that benefits from the extra bandwidth.
Final Verdict: Which Audio Interface Should You Buy in 2026?
The Focusrite Scarlett Solo 4th Gen is our pick for anyone starting with one microphone, because 120dB of dynamic range and a gain LED give you a clean, quiet recording with almost nothing to learn. The Behringer UMC404HD covers a panel of three or four people without a second purchase, and the Zoom PodTrak P4 is the one-box answer when four independent headphone outputs and automatic mix-minus for phone guests matter more than 24-bit capture.
Match the box to the number of voices in the room, set your gains before you record, and treat the room as the bigger half of the audio problem. When you are ready to look at the wider market, our picks for audio interfaces under $500 and streaming interfaces cover the neighbouring budgets and use cases.
