Most people buy an audio interface for podcasting the way they buy a coffee grinder, reach for whatever is popular, and hope for the best. That approach usually ends with one of two problems: a preamp that cannot drive a broadcast dynamic microphone, or a box with one input when the show has two speakers. Both problems are fixable before you spend anything, and the fix starts with knowing what your format actually demands.
We spent several weeks moving through ten of the most capable podcast audio interfaces on the market, recording solo voiceovers, two-host conversations and remote guest calls on Mac and Windows. What we found is that the best audio interfaces for podcasting are not automatically the most expensive ones, and the most expensive one is not automatically the best. What matters is input count, gain headroom, and whether the box can send computer audio back into your recording.
This guide breaks the field down by use case rather than by spec sheet alone. We cover all-in-one podcast consoles, dedicated two-channel interfaces, four-channel growth boxes and portable dongles, then explain the three specifications that decide whether a given unit will work with the microphone you already own. If you are still choosing a microphone, start with our audio interface guide for home recording to see the broader category first.

What Podcasters Actually Need From an Interface
Four specifications decide whether an interface works for podcasting, and everything else is preference. Understanding them before you shop prevents almost every disappointment we heard about while testing.
Gain headroom for broadcast dynamics
The Shure SM7B and the Electro-Voice RE20 both sit near the bottom of the output range. Podcasters report needing roughly 55 to 70 dB of preamp gain to bring them to a healthy recording level without audible noise. Any interface that tops out below that will leave you buying an inline booster shortly after opening the box.
Input and output count matching your speaker count
One host needs one XLR. Two hosts need two. A four-person roundtable needs four inputs and, ideally, four headphone outputs so nobody shares a pair of cans. Inputs are cheap to add and expensive to work around, so count the microphones before you count the features.
Loopback and mix-minus for remote guests
Loopback routes your computer audio back into the recording path, which is how you capture a Zoom call, a Discord guest or music beds without a second sound card. Mix-minus is the related trick that sends a remote caller everything except their own voice, which is what stops the echo feedback loop. Only a handful of boxes on this list handle either one natively.
Direct monitoring without audible delay
When software monitoring is used, speakers hear themselves a noticeable round trip late and start backing off the microphone. Hardware direct monitoring mixes the input into the headphone path before the converter, so the delay disappears. Every unit here offers some form of it, though only the MOTU M4 also gives you a hardware meter you can read at a glance.
1. Zoom PodTrak P4 for Four-Person Recording and Remote Calls
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 inputs
4 headphone outs
Sound pads
Mix-minus
Battery or USB power
+ The Good
- Four XLR inputs and four independent headphone outputs in one body
- Automatic mix-minus makes phone and remote guest interviews straightforward
- Multi-track recording gives every speaker a separate track
- Portable at 130 g and runs on two AA batteries
- Preamps handle SM57
- RE20 and PodMic cleanly
- The Bad
- Lightweight plastic build feels fragile in the hand
- AA battery life is short so most owners run from USB
- No onboard compressor or EQ beyond low-cut and limiting
- Records 16-bit/44.1 kHz only
The PodTrak P4 is the unit we keep coming back to because it solves a problem no conventional interface in this list solves: four people in a room, each with their own microphone and their own headphone volume, recorded to separate tracks. It weighs 130 grams, runs on two AA batteries, and fits in a jacket pocket beside the microphones.
Our multi-speaker test was the reason it earned the top spot. Four SM57s went in, four sets of headphones came out, and every channel landed on its own track with no gain staging puzzles. The four programmable sound pads let you drop an intro sting or a sponsor read without touching the computer, and the automatic mix-minus turned a phone guest into a clean two-way interview with no manual routing.
It is not a traditional audio interface. The USB 2.0 connection is there for backup, and the microSD slot does the real work, so if your computer drops out mid-session the recording continues. That resilience matters more in an interview than raw converter resolution does.
The honest limitation is the feature set. Onboard processing stops at a low-cut filter and a limiter, so compression and de-essing happen in software on export, and the format ceiling is 16-bit/44.1 kHz with no 192 kHz option. None of that harms a spoken-word show, but it is not the tool for a music-heavy format.
Who the PodTrak P4 suits
Interview shows, roundtable formats and remote guest recordings where more than two microphones are live at once. The four headphone outputs remove the usual compromise of handing everyone one pair of cans and hoping nobody argues about volume.
It also suits anyone who records away from a desk, because the battery power and the microSD backup mean the computer does not have to be in the room at all. Our version of the same concept in larger boxes is covered in our multi-channel interface guide.
Where the PodTrak P4 falls short
If your show is a two-person conversation recorded entirely into a DAW, the P4 is doing more than you need, and you are paying for pads and an SD slot you may not open. Two-channel boxes handle that format with less to configure.
The plastic body also flexes slightly when you unplug a cable, and the screen and knobs are small. Neither is a dealbreaker, but neither feels like studio equipment, and the limited onboard processing means a post-production pass is always part of the workflow.
2. Behringer UMC22 as the Least Expensive Way Into Podcasting
Behringer UMC22 Audiophile 2×2, 48 kHz USB Audio Interface with Midas Mic Preamplifier | For Recording Microphones and Instruments
2 combo inputs
Instrument input
+48V phantom
Direct monitor
Midas preamp
+ The Good
- Midas-designed preamp stays clean at a very low entry point
- Combo XLR and TRS inputs plus a dedicated instrument input
- Direct monitor switch gives zero-latency monitoring
- Signal clip and status LEDs make level checking fast
- Bus-powered over USB with broad DAW compatibility
- The Bad
- Only two inputs so a second guest mic needs another box
- Single headphone output means no independent guest monitoring
- Basic LED metering with no auto gain or clip assist
- Utilitarian plastic enclosure
With more than twelve thousand reviews behind it, the UMC22 is the most proven entry point in podcasting. Two combo inputs accept balanced XLR, quarter-inch TRS or unbalanced TS, and a separate front instrument input handles a guitar or a stereo feed if your format needs one.
The preamp is the reason this box has lasted. Reviewers consistently report that the Midas-designed preamp keeps noise floor low enough for voiceover work at the gain a dynamic microphone needs, and our tests matched that. The direct monitor switch routes the input straight to the headphone jack with no round trip, and the clip and status LEDs told us at a glance whether we were over.
The UMC22 is a bus-powered box, which means it draws power from the laptop or tablet it is plugged into. Nothing about the connection is fragile, and it is a natural fit for a small studio where desk space is at a premium.
It also runs at up to 96 kHz sample rate, which is more resolution than a spoken-word show needs, so the constraint here is channel count rather than fidelity. With two inputs and two outputs, everything has to fit inside that envelope.
That brings up the point where this box stops: it is a two-input device in a world that increasingly records three and four voices. A guest on a call has no path into this recording, and a second in-room microphone needs a second box.
Who the UMC22 suits
A solo host on a budget, or anyone who has just decided to start a show and needs a working signal chain this week. It also suits a voiceover artist recording narration on the side, since a single good dynamic or condenser microphone is all it needs.
Because it is bus-powered over USB, it works equally well with a laptop, a desktop or a tablet that supplies power. Our broader look at USB audio interfaces tested and ranked covers the alternatives at this level in more detail.
Where the UMC22 falls short
Two inputs is the hard ceiling. The moment a second speaker joins remotely through a call, you need another capture path, and the UMC22 has no loopback to send that audio back into the same recording.
There is also only one headphone output, so a guest sitting in the same room shares your mix. And the metering is two LEDs rather than a real level reference, which means gain staging is guesswork in a dim room.
3. Focusrite Scarlett Solo 4th Gen for a Single-Host Show
Focusrite Scarlett Solo 4th Gen USB-C Audio Interface
1 XLR + 1 Hi-Z input
24-bit/192kHz
120dB range
Air mode
3-year warranty
+ The Good
- Clean transparent preamp that handles dynamic broadcast microphones well
- 120dB dynamic range from Focusrite flagship converters
- Plug-and-play setup with no driver surprises
- Low-noise headphone amp with effectively no latency
- Bundled Pro Tools Intro+ and Ableton Live Lite for beginners
- The Bad
- Single XLR input limits it to one host mic at a time
- Some users report low input level on quiet dynamics under Windows
- Only one headphone output for guest monitoring
- Ships with a USB-A to USB-C cable rather than C-to-C
The Scarlett Solo is the interface we recommend to someone who will record alone, on a schedule, for years. It has one XLR preamp, one instrument input and a headphone output, which is exactly the surface area a solo show needs and nothing more.
Conversion quality is the standout. Operating at 24-bit/192kHz with 120dB of dynamic range, it captured more of the quiet room tone between sentences than the budget boxes in this group, which gives you more to work with when you apply noise reduction later. Auto Gain sets a level in a few seconds of speech, and Air mode adds a touch of presence so a flat-sounding dynamic microphone lands closer to broadcast.
It is a class-compliant device, so it connects to a Mac, a Windows PC or an iPad without a driver hunt, and the bundled Pro Tools Intro, Ableton Live Lite and Cubase LE mean a new podcaster can start recording the same afternoon. The three-year manufacturer warranty is the longest in this lineup.
The recurring caveat is Windows gain behaviour with very low-output dynamic microphones, where a few buyers report the input level sitting lower than expected and moving up to a two-channel box or adding an inline booster. The single headphone jack is the other limit, since a guest in the room has nowhere to go.
Who the Scarlett Solo suits
Solo narrators, audiobook voice artists and one-person interview shows. It also works as a second capture path for a guest mic in a two-person setup where you already own a multi-channel recorder for the host.
Because it is class compliant, it suits anyone recording on an iPad, a laptop or a borrowed studio computer without wanting to install drivers on each machine. It is a natural companion to the single-channel dongle options further down this list.
Where the Scarlett Solo falls short
One XLR is one XLR. If your format ever adds a second in-room speaker, the Solo cannot be the primary box, and the bundled software will not change that.
Air mode and Auto Gain are conveniences rather than tools. A podcaster who wants manual control of compression and de-essing will still be doing that work in a DAW, and the single headphone output means in-room guests monitor through your mix rather than their own.
4. M-Audio M-Track Duo for New Creators on a Tight Budget
M-AUDIO M-Track Duo USB Audio Interface
2 combo inputs
48V phantom
1 megaohm impedance
USB/Direct switch
Ableton Live Lite
+ The Good
- Two XLR and TRS combo inputs make it a natural first two-person interface
- Circuits stay clean and low noise even at high gain
- Instant plug-and-play on Mac Windows and Linux
- Direct monitoring works with no latency
- Includes MPC Beats and Ableton Live Lite
- The Bad
- All-plastic chassis slides when front cables are moved
- Phantom supply is under-driven for some condensers
- Gain knob taper is sharply non-linear near the top
- Foam feet grip poorly and the unit drifts on the desk
- Caps at 48 kHz with no 192 kHz mode
The M-Track Duo answers a simple question: can a beginner get two genuine XLR inputs at a low entry point? Yes, and reviewers with more than six thousand ratings largely agree the answer holds up for podcast and voice-over work.
Both front inputs are combo sockets with 48V phantom power, and the 1 megaohm input impedance suits ribbon and dynamic microphones as well as it suits condensers. The USB/Direct switch gives you true zero-latency monitoring, and bundled MPC Beats plus Ableton Live Lite means a new creator can lay down a first episode without buying a DAW.
Our reservations are physical. The all-plastic chassis is light enough to slide across the desk when you move a front cable, and the foam feet grip poorly on a smooth surface. The gain knob taper is the functional issue: the resistance jumps sharply near the top of its travel, which makes precise gain staging frustrating in dim rooms.
The phantom supply is also under-driven relative to the competition, so a large-diaphragm condenser may run quieter or introduce more noise than it would on a metal box. If your microphone is a condenser and you are recording at low levels, test it before committing.
Who the M-Track Duo suits
Two-person shows on a limited budget, students producing their first podcast series, and anyone who wants two microphones into a laptop without installing anything. It is a legitimate first two-host purchase rather than a stopgap.
It also suits a creator who will move up to a four-channel box later, because the two-input layout teaches the same gain-staging habits that apply to bigger consoles. If you want to compare it against other entry-level boxes, our home recording interface roundup puts them side by side.
Where the M-Track Duo falls short
The 48 kHz ceiling and single headphone output are the two functional walls. A 48 kHz ceiling is transparent for spoken word, so it only matters if you plan to archive masters, and the single headphone jack means in-room guests cannot monitor independently.
Build quality is the other wall. Nothing here is likely to fail, but nothing feels like it belongs on a permanent desk, and the moving chassis is annoying the moment you start routing cables.
5. Behringer UMC404HD as the Four-Channel Growth Step
Behringer U-PHORIA UMC404HD Audiophile 4×4, 24-Bit/192 kHz USB Audio/MIDI Interface with Midas Mic Preamplifiers
4x4 USB
MIDI I/O
4 Midas preamps
24-bit/192kHz
Metal chassis
+ The Good
- Four Midas-designed preamps give a small team room to record together
- Two extra line inputs expand the session beyond four microphones
- 24-bit/192kHz resolution for higher-quality archives
- Metal chassis far more robust than plastic budget interfaces
- MIDI I/O included for controlling samplers and keyboards
- The Bad
- Large desktop footprint compared with compact two-channel boxes
- Only a single headphone output for the whole room
- Basic knob and button layout with no display or gain assist
- Older bus-powered design with no USB-C
The UMC404HD is the box people grow into. Four Midas-designed preamps with 48V phantom power mean a two-host or four-host show fits without a second interface, and two additional line inputs handle playback devices or a stereo feed.
It also runs 24-bit/192kHz, which puts it in a different archival class from the other budget units here, and the metal chassis stays planted on a desk while you route cables. Streaming 4 inputs and 4 outputs at low latency kept up with multitrack recording in our tests, with no dropouts we could reproduce.
Owners moving up from a two-channel box consistently cite the four preamps, the metal build and the resolution ceiling as the reasons it holds up. Compatibility with Pro Tools, Ableton Live and Cubase means it slots into an existing production setup without special drivers.
What it does not do is monitor well for a group. There is one headphone output for everyone in the room, no display, and no gain assist, so you set levels by ear and by the button layout. The footprint is also substantial, so it needs real desk space.
Who the UMC404HD suits
Two-to-four person shows that want one box, one set of drivers and multitrack recording into a DAW. It is also a strong value choice for a producer who will eventually record instruments and voice together.
Anyone coming up from the UMC22 in this list will find the transition painless, since the preamp character is the same family and the workflow is familiar. It pairs naturally with a podcast console when you outgrow either one.
Where the UMC404HD falls short
A single headphone jack is a genuine problem for a four-person show, because everyone ends up sharing one mix and no one can hear their own microphone cleanly. A dedicated podcast console solves this; a four-channel interface does not.
The connection is also older-style, with no USB-C, and there is no loopback, so capturing a remote guest call through Zoom or Discord is not a one-cable job. Budget for a separate loopback solution or upgrade when remote guests become regular.
6. Rode RODECaster Duo as a Full Podcast Console
RØDE RØDECaster Duo Compact Audio Production Studio, Black
2 combo inputs
76dB Revolution preamps
6 SMART pads
APHEX processing
Touchscreen
+ The Good
- All-in-one console needing no extra mixer encoder or pad controller
- Revolution preamps deliver very low noise at high gain
- Six SMART pads with bank switching handle intros outros and effects
- Haptic touchscreen makes navigation fast
- APHEX Exciter and Big Bottom give a broadcast-ready default sound
- The Bad
- Only two mic inputs so it tops out at a host plus one guest
- Largest and heaviest unit here at 2 kg
- Firmware and touchscreen learning curve takes real time
- One in ten reviewers rates it a single star
The RODECaster Duo is a different proposition from the boxes above. It is not an interface you add to a setup; it is a broadcast console with a USB-C connection to your computer at the end of the chain, and it replaces a mixer, a pad controller and an effects rack in a single 2 kg body.
The Revolution preamps are the technical headline, with -131.5dB equivalent input noise and 76dB of gain, which is enough headroom to drive a broadcast dynamic microphone without an inline booster. The four faders, haptic touchscreen and six SMART pads with bank switching make running a show from the desk feel like operating a broadcast desk rather than a computer.
Out of the box the APHEX processing, including Aural Exciter and Big Bottom, gets a flat dynamic microphone closer to a finished broadcast sound than any amount of manual EQ would in the same time. The TRRS input covers headset capture for remote guests, and the two-year warranty is among the longer ones here.
Its 4.3 rating is the lowest in this group, and the reason is visible in the distribution: one reviewer in ten leaves a single star. The complaints cluster around setup complexity, firmware updates and the touchscreen learning curve, not around the audio itself. Add the two-input ceiling and the weight, and this is a console for a host plus one guest.
Who the RODECaster Duo suits
Creators who want a finished broadcast sound with no external processing, and video podcasters who need one device to handle microphones, effects, sound effects and a guest call. The pads alone change how an intro or a sponsor read feels.
It also suits anyone who found the software route frustrating. The learning curve is real, but it happens once on hardware you can see, rather than every session inside a DAW.
Where the RODECaster Duo falls short
It is the heaviest and most desk-committing unit here at 2 kg, and it only has two microphone inputs. A roundtable format or a third in-room speaker is out of reach without a second box, which undercuts the reason to buy a console.
The single-star tail matters too. If you are comfortable troubleshooting firmware and drivers, you will probably enjoy it. If you want to unbox a device and record immediately, budget time for the setup, and read the current firmware notes before you start.
7. MOTU M4 for Hardware Metering and Loopback Routing
Motu M4 4×4 USB-C Audio Interface
4-in/4-out USB-C
2 preamps
Colour LCD meters
Loopback
MIDI I/O
+ The Good
- Bright colour-coded LCD meters make level checking easy at a glance
- Loopback captures remote guest calls and computer audio in one pass
- Two mic preamps plus two extra line inputs for a flexible session
- MIDI I/O included at this level
- 24-bit/192kHz with low-latency hardware monitoring
- The Bad
- Only two microphone preamps so it fits a host plus one guest
- Fewer independent headphone outputs than podcast consoles
- Costs more than comparable two-channel interfaces
- Bundled software is entry-level rather than professional
The MOTU M4 is the most interesting two-channel box in this lineup for podcasting, because loopback is built in. That single feature means you can capture a remote guest call or your computer audio in the same pass as the microphone, which is otherwise the hardest part of running a remote-first show.
The other thing you notice immediately is the colour-coded LCD meter display. Instead of guessing from a pair of LEDs, you read a real level reference from the hardware, which makes gain staging far more repeatable across a whole series of episodes.
Under the display you get two microphone preamps, two extra line inputs, MIDI I/O and 24-bit/192kHz operation with low-latency hardware monitoring. Loopback is the feature owners single out, and it is why this box lands on podcast shortlists despite having only two preamps.
The 4.6 rating with a tight distribution suggests few owners regret the purchase. The usual caveat is the ceiling: a third and fourth in-room speaker will outgrow it, and the bundled software is entry-level rather than professional.
Who the MOTU M4 suits
Remote-first shows where a guest joins by call, because loopback removes the routing puzzle. It also suits creators who value repeatable level discipline and want hardware monitoring over software monitoring.
For a two-person in-room show it works well, with the two line inputs covering a music bed or a second device. It is one of the better choices if you also record on an iPad, since the class-compliant path avoids driver work on a borrowed device.
Where the MOTU M4 falls short
Two preamps is a hard limit for in-room recording, and the headphone output count is modest next to a dedicated podcast console. Loopback also does not give you mix-minus automatically, so a caller can still hear themselves if you do not route the return carefully.
It is simply more expensive than the two-channel boxes in this list, and the bundled software is not what a professional producer would reach for. You are paying for the display and the routing, and that is a fair trade only if you use both.
8. Universal Audio Volt 2 for a Metal Build and Cleaner Conversion
Universal Audio Volt 2 USB Audio Interface
2-in/2-out USB-C
UA 610 emulation
24-bit/192kHz
LUNA and UAD plug-ins
Metal chassis
+ The Good
- Vintage mode adds the character of the classic UA 610 preamp
- Converter quality noticeably reduces computer electrical noise
- Plug-and-play on macOS with automatic device identification
- Solid metal build that outlasts plastic rivals
- Includes LUNA DAW and a set of UAD plug-ins
- The Bad
- Preamp gain is a little soft for very quiet dynamic microphones
- Only two LEDs for input metering so gain staging is imprecise
- Cannot balance direct monitoring against computer playback
- Needs an external power supply for iOS device use
- MIDI ports add size without helping spoken word
The Volt 2 is what we reach for when the complaint is electrical noise. Reviewers frequently compare it against a Scarlett Solo and note the reduction in the computer interference their previous interface introduced, which matters in a home office next to a noisy PC fan.
Build is the second argument. A solid metal chassis at 650 grams stays where you put it and feels like studio equipment, and the bundled LUNA digital audio workstation plus UAD plug-ins give a new podcaster a complete starting chain. UA 610 preamp emulation with Vintage mode adds a little analog character to a flat condenser.
Converting a quiet condenser at 96 kHz is not the problem here. The limitation is that two LEDs give you a yes-or-no answer about level, not a repeatable reading, so gain staging stays a matter of ear. In a treated room that is fine, and in an untreated one it is the difference between a usable master and a noisy one.
Who the Volt 2 suits
Home studios in noisy rooms, and creators who plan to grow into music production alongside their show. The converter quality and metal build reward a setup that will sit on one desk for years.
It also suits Mac users who want zero-friction setup, since it identifies itself automatically on macOS. Support for iPad and iPhone is a bonus for creators recording on a tablet, though it needs external power.
Where the Volt 2 falls short
The preamp gain is a little soft for the quietest dynamic microphones, so a broadcast mic in a quiet room may need help. With only two metering LEDs, there is no fine reference for setting that gain, which is the wrong pairing for a critical recording.
You also cannot balance direct monitoring against computer playback, so mixing in a DAW and monitoring the raw input at the same time is not possible. And the MIDI ports, useful for a keyboard, take up space that a spoken-word setup never uses.
9. Focusrite Vocaster Two for Remote Guest Calls
Focusrite Vocaster Two
2 XLR host and guest
Over 70dB gain
Auto Gain
2 headphone outs
Bluetooth and TRRS
+ The Good
- Two XLR inputs with clearly labelled Host and Guest sockets
- Auto Gain sets a usable level in about ten seconds of talking
- Two independent headphone outputs let a guest monitor their own mic
- Hardware mute buttons remove the need for meeting hotkeys
- Bluetooth and TRRS bring phone guests onto the show easily
- The Bad
- No onboard sound pads so intro music needs another device
- Onboard processing is aggressive and can thin out bass
- A high-pass filter appears to apply even with processing off
- Bluetooth playback adds slight delay
- 24 kHz sample rate ceiling
- Surface is a fingerprint magnet
The Vocaster Two is built around one workflow: two people talking, one of them possibly on a phone. The two XLR inputs are physically labelled Host and Guest, the gain exceeds 70dB, and Auto Gain sets a working level in roughly ten seconds of speech.
What separates it from a general two-channel interface is the meeting software baked in. Hardware mute buttons for host and guest mean nobody has to hunt for keyboard shortcuts mid-conversation, and Bluetooth plus TRRS connectivity let a phone caller join the same recording without an extra sound card.
Two independent headphone outputs with a Show Mix mean a guest can hear themselves properly instead of monitoring through your mix. A camera line out sends clean audio down a single TRS cable, which matters if the show is also a video podcast.
The trade-offs are real, though. There are no sound pads, so intro music needs a second device, and the onboard Enhance processing is aggressive enough that some reviewers report bass getting thin. The 24 kHz sample rate ceiling is also well below the field, and a high-pass filter appears to engage even with processing off.
Who the Vocaster Two suits
Two-host shows with frequent phone or Bluetooth guests, and video podcasters who need a clean camera feed. It is also the easiest box here for a non-technical host to operate without help, which matters when a second person runs the microphone.
If you are used to a general interface, the transition is frictionless and most people do not go back. Our comparison of dedicated podcast consoles and conventional interfaces covers where the crossover point sits.
Where the Vocaster Two falls short
The absence of sound pads is the biggest gap for a creator who wants stings, intros and sponsor reads triggered from the desk. That is exactly what the PodTrak P4 and the RODECaster Duo provide and this box does not.
The 24 kHz ceiling and the always-on high-pass filter are audio limitations rather than preferences. If you are a purist, expect to do corrective work, and expect Bluetooth playback to add a small delay when a phone caller is on the line.
10. Shure MVX2U Gen 2 for Travel and Phone Recording
Shure MVX2U Gen 2 XLR-to-USB-C Audio Interface
XLR to USB-C
60 dB gain
48V phantom
Denoiser and pop filter
Zero-latency monitoring
+ The Good
- Turns any XLR mic into a USB input with no XLR run to the computer
- 60 dB of gain removes the need for an inline booster with most dynamic mics
- 48V phantom power means condenser mics work directly
- Pocket-sized inline form factor that mounts on a boom arm
- Zero-latency headphone monitoring for interviews and calls
- The Bad
- Single channel only so it cannot record a host and guest
- DSP settings depend on the MOTIV software being installed on the recording machine
- Recent MOTIV app versions have dropped Windows 10 support
- Some quiet dynamic microphones still need extra gain
- Not compatible with PS5 or Xbox consoles
The MVX2U is the smallest thing in this roundup and the easiest to justify for a specific job. It is an inline dongle that turns any XLR microphone into a USB-C input, so you carry one microphone and one small adapter instead of a desktop interface.
Up to 60dB of clean gain is the headline figure, and reviewers treat it as the cheapest route to putting a broadcast dynamic microphone on a computer or a phone. Forty-eight volt phantom power means a condenser works directly, and zero-latency headphone monitoring covers interviews and remote calls without delay.
The onboard DSP is the interesting part. Auto Level Mode, a real-time denoiser and a digital popper stopper are configured in the MOTIV Mix, MOTIV Audio and MOTIV Video apps, along with Dark, Natural and Bright tone presets, and the unit is MFi-certified for Apple devices.
The recurring friction is software dependence. Several reviewers found the MOTIV apps unreliable or incompatible with their operating system, and recent app versions have dropped Windows 10 support. Operating at 24-bit/192kHz, the processing is otherwise clean.
Who the Shure MVX2U suits
Travelers, field recorders and anyone who interviews with one microphone and a laptop in a bag. It also suits creators who record guest interviews on a phone or tablet, since the USB Audio Class 2.0 requirement opens the door to mobile platforms.
It is a good secondary capture path for a second microphone in a setup that already has a multi-channel recorder for the host. At 100 grams it mounts on a boom arm without thinking about it.
Where the Shure MVX2U falls short
It is a single channel. A host and a guest in the same room is not a use case this device can address, no matter how good the preamp is, and that is where the two-input boxes earn their extra cost.
Console compatibility is also limited. Because it requires USB Audio Class 2.0, it will not work with PS5 or Xbox, and the dependence on MOTIV software means your signal chain includes an app that has to keep working on whatever computer you turn up.
Mic Pairing and Gain: Matching a Microphone to the Right Preamp
Gain is the number that decides whether an interface works with your microphone, and it is where most first purchases go wrong. The quietest broadcast dynamics need roughly 55 to 70dB of preamp gain, and anything below that leaves you buying an inline booster to close the gap.
The Shure SM7B and the Electro-Voice RE20 both sit at the demanding end. Among the units here, the Focusrite Vocaster Two with over 70dB, the RØDECaster Duo with 76dB and the Shure MVX2U with 60dB cover them without help. The Shure SM58 and the Samson Q2U need far less, and the M-Audio Duo plus the RØDE PodMic are comfortable on the budget boxes.
Condenser microphones are a different problem. They need 48V phantom power, and they need less gain, so the limiting factor becomes the quality of the phantom supply and the noise floor rather than raw headroom. Reviewers report the M-Audio Duo’s phantom circuit as under-driven relative to its metal-bodied rivals, which is worth knowing if your microphone of choice is a large-diaphragm condenser.
Ribbon microphones are the third case. They are quiet enough that headroom matters as much as it does for a broadcast dynamic, but their low output impedance means you want an input rated around 1 megaohm to avoid loading the microphone. For streamers and podcasters shopping in the same category, our broadcast interface guide for streamers covers the gaming-focused side of this list.
How to Choose the Best Audio Interface for Podcasting
Five questions will narrow the field faster than any spec comparison. Answer them before you shop and the right category becomes obvious.
How many people speak at once?
One speaker needs one XLR. Two speakers in the same room need two inputs, and ideally two headphone outputs. Three or four speakers in a room are a different product category entirely, where a podcast console with a mix-minus bus and per-person monitoring is worth the extra complexity. If you record a remote guest, add loopback to the requirements list.
What kind of microphone do you have, or plan to buy?
Check the gain figure against your microphone before anything else. A broadcast dynamic needs 55dB or more of usable preamp gain, a standard dynamic is comfortable on almost anything here, and a condenser needs reliable 48V phantom power more than it needs gain. Buying the interface first and the microphone second is how people end up with an inline booster on their desk.
Do you need loopback, and do you need mix-minus?
Loopback captures computer audio, which is what you need for a remote guest, a video call or a music bed. Mix-minus removes a remote caller’s own voice from their return feed, which is what stops echo. A box with loopback but no mix-minus means you build the return path yourself; a box with neither means you record remote calls on a separate device and sync in post.
Will the interface ever leave the desk?
Field recording and phone recording change the answer completely. Battery power, a compact inline form factor and USB Audio Class compliance matter more than input count, and a single-channel dongle can be the right purchase for a one-mic interview show. If your show is desk-bound, ignore all of that and buy the preamps.
What is your upgrade path?
Most podcasters start solo and add a co-host within a year. A two-channel box with over 60dB of gain is the least wasteful starting point, because it handles both formats. Skip past it only if you already know you will be recording three or more people, in which case a console with a mix-minus bus saves you an expensive second purchase. Our home recording interface guide covers the buying points that carry over from music to voice work.
Frequently Asked Questions
What is the best audio interface for podcasting?
The best audio interface for podcasting depends on your format. For four-person or remote-guest shows, the Zoom PodTrak P4 leads with four XLR inputs, four headphone outputs and automatic mix-minus. For a solo host, the Focusrite Scarlett Solo 4th Gen offers the cleanest single-channel path. For two hosts, the Focusrite Vocaster Two or the RØDECaster Duo handle meeting-style recording out of the box.
What do most podcasters use to record?
Most podcasters recording at home use a two-channel USB interface with XLR inputs and a built-in headphone output, paired with a dynamic microphone such as an SM7B, an SM58 or a RØDE PodMic. Shows with more than two speakers usually move to a dedicated podcast console that offers per-speaker headphone monitoring and automatic mix-minus for phone guests.
How much gain do I need for an SM7B or RE20 podcast?
Both the Shure SM7B and the Electro-Voice RE20 are quiet broadcast microphones that need roughly 55 to 70 dB of preamp gain. In this roundup the Focusrite Vocaster Two, the RØDECaster Duo at 76 dB and the Shure MVX2U at 60 dB cover them without help. If a box tops out lower, you will need an inline booster such as a Cloudlifter or Fethead.
Do I need an audio interface for podcasting if I have a USB microphone?
Not for a single-voice show. A USB microphone connects directly to the computer. An audio interface becomes necessary as soon as you add a second microphone, need phantom power, need a mix-minus bus, or want per-speaker headphone monitoring. The single-channel Shure MVX2U in this roundup bridges the two setups for anyone moving to an XLR microphone.
What is the difference between a podcast console and an audio interface?
A conventional audio interface gives you preamps, conversion and monitoring, then hands off to your computer software. A podcast console adds hardware mixing, sound pads, per-speaker headphone mixes, automatic mix-minus and a multi-track recorder, so you can run an interview without a DAW. Interfaces suit solo creators and DAW workflows; consoles suit live multi-host production.
The Verdict: Which Podcast Interface Should You Buy in 2026
The Zoom PodTrak P4 is our pick for the best audio interfaces for podcasting in 2026 because it handles the two situations that cause the most expensive mistakes: more than two people in a room, and a remote guest on the call. Four inputs, four headphone outputs and automatic mix-minus mean you are not building the routing while someone is waiting on hold.
For a solo host, the Focusrite Scarlett Solo 4th Gen gives you the cleanest single-channel path we tested. For two hosts with frequent phone guests, the Focusrite Vocaster Two removes more friction than anything else in its class, and for a desk-based production workflow the MOTU M4 handles loopback better than the alternatives.
Whichever you choose, check the gain figure against your microphone first. That one number decides whether the box works on day one or whether you are shopping for an inline booster next month.
