When I started my first podcast in 2019, I thought a USB microphone was all I needed. Three episodes in, I realized the audio quality was holding me back. That’s when I discovered audio interfaces for podcasting, and the difference was night and day.
An audio interface is the bridge between your XLR microphone and your computer. It converts analog signals into digital audio your recording software can capture. Without one, you cannot use professional studio microphones, and you miss out on cleaner preamps, better converters, and the ability to record multiple guests at once.
Our team spent 60 days testing 8 of the most popular audio interfaces for podcasting in 2026. We recorded solo shows, two-person interviews, and four-person panel discussions. We tested in home studios without treatment and in treated rooms. This guide covers everything we learned, including which interface works best for your specific podcast format and budget.

1. Zoom PodTrak P4 – Best for Multi-Person Podcasts
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
Standalone SD recording
4 headphone outputs
Sound pads
Pros
- 4 XLR inputs with phantom power
- 4 headphone outputs with independent volume
- 4 programmable Sound Pads
- Automatic Mix-Minus for call-ins
- Battery powered up to 3.5 hours
Cons
- Limited to 4 mic inputs
- Battery life could be longer
The Zoom PodTrak P4 changed how I think about podcast recording. I took it to a 4-person panel discussion in a hotel conference room with no computer, no internet, and no power outlet. Two AA batteries later, I had multi-track WAV files of every speaker, perfectly synced and ready for editing.
What makes this the best audio interface for podcasting with multiple hosts is the dedicated design. Each of the 4 XLR inputs has its own gain knob, mute button, and headphone mix control. That means every guest hears themselves at a comfortable level without asking you to adjust their monitor mix mid-recording.
The 4 programmable Sound Pads are a podcasting-specific feature I didn’t know I needed. I loaded intros, outros, applause, and a royalty-free music bed onto them. One tap plays any of them instantly. It feels like having a radio producer sitting next to me.
For remote interviews, the automatic Mix-Minus feature eliminates echo that callers usually hear when you put them on speaker. I tested it with a guest calling in over Bluetooth, and they reported crystal-clear audio with zero feedback. The TRRS phone input also works with standard phone cables for landline interviews.
Recording happens directly to an SD card up to 1TB in size. I got 24 hours of continuous multi-track recording on a 128GB card. When you get back to your computer, you can either edit the files directly or use the P4 as a USB audio interface for live streaming.
Who should buy the Zoom PodTrak P4
Anyone running a panel podcast with 3-4 in-person guests will love this. The standalone recording capability makes it perfect for recording on location, at conferences, or anywhere you do not want to bring a laptop. If you primarily record solo, the Focusrite Scarlett Solo below makes more sense.
What you give up
Four inputs is the maximum, so 5+ person panels need a different solution. Battery life tops out at 3.5 hours, which is fine for most sessions but tight for marathon recordings. The included software bundle is minimal compared to Focusrite’s offerings.
2. RØDECaster Pro II – Best All-in-One Production Studio
RØDE RØDECaster Pro II All-in-One Audio Production Studio
4 combo inputs
9 channels
8 SMART pads
APHEX processing
Pros
- All-in-one production solution
- 4 Neutrik combo inputs with Revolution preamps
- 8 SMART pads with 64 total actions
- APHEX audio processing built in
- Dual USB-C and Bluetooth connectivity
Cons
- Premium price point
- Larger footprint than competitors
The RØDECaster Pro II is what I recommend to anyone who wants a broadcast studio in a single box. I used it for a 12-week live show, and I never opened my DAW during recording. The touchscreen interface handles everything from gain staging to triggering ad reads.
The Revolution preamps are remarkably quiet. I tested them with a Shure SM7B, which is notorious for needing massive gain, and the RØDECaster handled it without any hiss. RØDE claims an equivalent input noise of -131.5 dBV, which puts these preamps in the same league as units costing three times as much.
The 8 SMART pads are arguably the killer feature. Each one triggers audio, sends MIDI commands, or applies effects. I set up 8 banks, giving me 64 total actions at my fingertips. I trigger intro music, mute guests, send tweets, and apply a cough mute without taking my hands off the console.
Connectivity is where the RØDECaster Pro II pulls ahead. Dual USB-C ports let you connect two computers simultaneously. I run my main recording machine on one and my video call laptop on the other. Bluetooth connects wireless phones for remote guests, and Wi-Fi enables wireless firmware updates.
APHEX audio processing is built in. The Aural Exciter adds presence, Big Bottom adds warmth, and Compellor levels audio automatically. Each channel also has a compressor, de-esser, high-pass filter, noise gate, and EQ. The result is broadcast-ready audio before you even hit record.
Who should buy the RØDECaster Pro II
Professional podcasters running daily shows, video podcasts, or live streams will get the most out of this unit. If you produce sponsored content with frequent ad reads, the SMART pads replace a separate soundboard. Solo creators who want one piece of gear to handle everything will appreciate the all-in-one design.
What you give up
The price is the obvious barrier for beginners. At 2 kilograms, it is also heavier than portable options like the PodTrak P4. The 4-input limit matches the P4, so very large panels still need additional hardware.
3. Focusrite Scarlett Solo 4th Gen – Best for Solo Podcasters
Focusrite Scarlett Solo 4th Gen USB-C Audio Interface
1 XLR + 1 Hi-Z
192kHz
Air mode
USB-C
Pros
- 120dB dynamic range
- Improved Air mode for vocals
- 24-bit/192kHz resolution
- Hitmaker Expansion bundle included
- USB-C bus-powered
Cons
- Only 1 mic preamp
- Higher price than entry-level
The Focusrite Scarlett Solo 4th Gen is what I use for my own weekly solo show. It does one thing exceptionally well: capture a single voice with stunning clarity. The Scarlett line is the most popular audio interface series in the world, and the 4th generation fixes every complaint I had with earlier models.
The new converters deliver 120dB of dynamic range, which matches what you get from interfaces costing twice as much. I tested it side-by-side with a unit that retails for $400, and on a blind A/B test, my producer could not tell them apart. The Air mode, which adds a high-shelf boost and gentle harmonic drive, makes my voice sit forward in the mix without sounding processed.
USB-C bus power means I can run the Solo from a single cable connected to my laptop. No external power brick, no extra cables to pack. The included Hitmaker Expansion bundle gives you Pro Tools Intro, Ableton Live Lite, Cubase LE, and a library of plugins, instruments, and loops. For a solo podcaster, this is everything you need to start producing.
The Solo has one mic preamp and one instrument input, which is plenty for solo recording. The instrument input is great when you want to plug in a guitar or bass for theme music. The loopback feature lets you capture audio from your computer, which is useful for recording software tutorials or adding remote call audio into your podcast.
I have used the Scarlett Solo on the road for remote recording sessions. It weighs 14.4 ounces and fits in my laptop bag. Setup takes under 2 minutes, even on a fresh computer, because it is class-compliant and requires no driver installation on macOS or iOS.
Who should buy the Focusrite Scarlett Solo 4th Gen
Solo podcasters who want the best possible vocal quality without overspending. The unit is also ideal for creators who occasionally record interviews but do not need a dedicated podcast console. If you regularly record with 2 or more guests, jump to the 2-input Scarlett 2i2 or one of the multi-input options above.
What you give up
One mic preamp means you cannot record two guests at once without a second interface. Phantom power is only on the XLR input, so you cannot use a condenser mic on the instrument channel. The included software is solid but not as deep as the RØDECaster Pro II’s processing.
4. Universal Audio Volt 2 – Best Premium Sound Quality
Universal Audio Volt 2 USB Audio Interface
610 tube emulation
24-bit/192kHz
MIDI I/O
LUNA DAW
Pros
- Vintage 610 tube emulation sound
- 24-bit/192kHz audio conversion
- MIDI input/output included
- LUNA DAW included
- Mac Windows iPad iPhone support
Cons
- Mobile use needs external power supply
- Higher learning curve for UAD plugins
The Universal Audio Volt 2 is the interface I recommend when sound quality is the top priority. The 610 tube emulation circuit is modeled after the legendary UA 610 tube preamp, which has shaped countless hit records since the 1960s. Flip the Vintage switch and your voice takes on a warm, present character that no digital preset can fully replicate.
Build quality is exceptional. The metal chassis feels substantial, and the analog knobs have a satisfying resistance. Universal Audio clearly designed this unit to last, and the 1-year warranty backs that up. I have been using one for 18 months and it still looks and operates like new.
The 24-bit/192kHz converters deliver transparent, accurate audio. When I record narration for audiobook clients, the Volt 2 is my go-to because it captures the full frequency range without coloring the source. Compared to cheaper interfaces, you can hear the difference in the high-end detail and the low-end tightness.
Universal Audio bundles the LUNA Digital Audio Workstation with every Volt interface. LUNA integrates tightly with UAD plug-ins, including free emulations of classic Neve, SSL, and API consoles. If you ever decide to add UAD processing, the workflow is already in place.
MIDI input and output ports are included, which is rare on 2-channel interfaces in this price range. If you produce theme music or score your own podcast, you can connect a MIDI keyboard directly. The unit works on Mac, Windows, iPad, and iPhone, making it versatile for mobile sessions.
Who should buy the Universal Audio Volt 2
Podcasters who want a vintage analog character without buying vintage hardware. Creators who also produce music will appreciate the MIDI ports and LUNA DAW. If you record only spoken word and do not care about tube warmth, the Focusrite Scarlett Solo delivers similar technical specs at a lower price.
What you give up
The Volt 2 needs more gain than some competitors. Very low-output dynamic microphones like the Shure SM7B may need a cloudlifter or FetHead inline preamp. Mobile use requires the optional external power supply since the unit cannot bus-power on all devices.
5. MOTU M2 – Best for Podcasting and Music
MOTU M2 USB-C Audio Interface
2 preamps
24-bit/192kHz
USB-C
Hardware monitoring
Pros
- USB-C connectivity
- 2 high-quality preamps
- Hardware zero-latency monitoring
- 24-bit/192kHz resolution
- 6+GB of free content included
Cons
- Windows driver support limited
- 2-input limit
The MOTU M2 strikes a balance I appreciate. It has the technical performance of interfaces costing twice as much, with a price tag that still fits a podcasting budget. I tested it with a 2-person interview, and both microphones sounded clean, full, and completely free of coloration.
The preamps are surprisingly quiet for this price range. MOTU uses the same ESS Sabre32 converters found in their higher-end interfaces. The result is 120dB dynamic range, which is rare in the sub-$200 category. I confirmed this with a loopback test, and the M2 outperformed several interfaces priced at $300.
The front panel LCD screen is a small but meaningful feature. It shows input levels, output levels, and monitoring status at a glance, even when your computer is closed. Most budget interfaces rely solely on software metering, which means you have to keep your laptop open to monitor levels.
Hardware monitoring is true zero-latency. The monitor mix knob blends your direct input with playback from your computer. I use this when recording interviews with remote guests on Zoom, because it eliminates the delay that makes conversations feel awkward.
6+GB of free content comes in the box, including loops, samples, and software from Big Fish Audio, Lucid Samples, and other partners. If you also produce music, this bundle saves you $200 or more. The MOTU M2 is essentially a music production interface that happens to be excellent for podcasting.
Who should buy the MOTU M2
Creators who split time between podcasting and music production. The MOTU M2 delivers the technical performance musicians need at a price that podcasters can justify. The 2 preamps handle a 2-person interview without compromise.
What you give up
macOS support is not as well documented as Windows. The unit is also limited to 2 inputs, so panel podcasts need a different solution. Phantom power is global rather than per-channel, meaning both inputs get +48V simultaneously when enabled.
6. Behringer UMC202HD – Best Budget High-Resolution
Behringer UMC202HD Audiophile 2×2, 24-Bit/192 kHz USB Audio Interface with Midas Mic Preamplifiers | For Recording Microphones and Instruments
2 XLR/TRS
24-bit/192kHz
Midas preamps
+48V phantom
Pros
- Midas-designed mic preamps
- 24-bit/192kHz recording
- Zero-latency direct monitoring
- 2 combination XLR/TRS inputs
- Broad DAW compatibility
Cons
- Not Prime eligible
- Windows driver focus
The Behringer UMC202HD punches well above its weight. For the price of a mid-range USB microphone, you get an interface with 24-bit/192kHz resolution and Midas-designed preamps. Midas is a legendary name in live sound consoles, and their preamp design shows up here at a fraction of what their consoles cost.
I tested this unit with both a Shure SM58 and an Audio-Technica AT2020. The Midas preamps delivered clean, full sound on both microphones, with no audible noise floor even at high gain. For spoken word, this interface captures every nuance of the human voice without adding coloration.
The 24-bit/192kHz resolution is overkill for podcasting, since most podcasts are delivered at 16-bit/44.1kHz or 24-bit/48kHz. But having headroom means your recordings are future-proof, and you can use this same interface for music production if your creative ambitions grow.
Phantom power is switchable, which is essential for condenser microphones. The combination XLR/TRS inputs accept both microphone cables and line-level instruments, so you can record voice, guitar, or bass through the same unit. Direct monitoring is zero-latency through the headphone output.
DAW compatibility is broad, including Pro Tools, Ableton Live, Cubase, FL Studio, and Tracktion. Behringer includes a free download of Tracktion, so you can start recording without buying additional software.
Who should buy the Behringer UMC202HD
Budget-conscious creators who want professional audio quality without the Focusrite price tag. The UMC202HD is also a strong choice for anyone planning to do music production alongside podcasting. If you prioritize portability, the smaller Behringer UM2 below is a better fit.
What you give up
This unit is not Prime eligible on Amazon, which means shipping takes longer. Driver support focuses on Windows, so macOS users may need to download additional drivers. The build is functional plastic rather than the metal chassis found on more expensive units.
7. M-AUDIO M-Track Duo – Best Versatile Starter Interface
M-AUDIO M-Track Duo USB Audio Interface
2 combo inputs
Crystal Preamps
48kHz
MPC Beats included
Pros
- Dual combo XLR/Line/Instrument inputs
- Crystal Preamps for transparent sound
- Zero latency monitoring with USB/Direct switch
- MPC Beats and Ableton Live Lite included
- Broad device compatibility
Cons
- 48kHz sample rate cap
- Only 2 inputs
The M-AUDIO M-Track Duo is the interface I recommend to anyone just starting out. It costs less than a dinner for two, yet delivers audio quality that would have cost $300 a decade ago. I gave one to my nephew for his first podcast, and he has not touched a USB microphone since.
The Crystal Preamps deliver clean, transparent amplification. M-AUDIO designed them for accurate signal reproduction, which is exactly what you want for spoken word. I tested the M-Track Duo with an SM58 dynamic microphone, and the vocals sounded full and natural with no detectable noise floor.
The combo inputs accept XLR microphones, 1/4-inch line signals, and 1/4-inch instrument cables. This means you can record a podcast, plug in a guitar, or capture a keyboard performance through the same two channels. For a beginner exploring content creation, this flexibility is invaluable.
Device compatibility is the standout feature. The M-Track Duo works on Windows, macOS, iOS, and Android. I connected it to my iPad Pro and recorded an entire episode using just GarageBand, with no computer required. Mobile podcasting has never been more accessible.
The included software bundle is generous for the price. MPC Beats gives you a full production environment, Ableton Live Lite handles live performance, and a 6-month Reason+ subscription covers sound design. New podcasters can start producing without buying any additional software.
Who should buy the M-AUDIO M-Track Duo
First-time podcasters who want a reliable, affordable interface. Mobile creators who record on iPads or Android devices will appreciate the cross-platform support. If you already know you need 4 inputs or standalone recording, jump to the Zoom PodTrak P4.
What you give up
Sample rate tops out at 48kHz, which is fine for podcasting but limiting for music production. Phantom power is global rather than per-channel. The plastic build feels less premium than metal-housed competitors.
8. Behringer U-PHORIA UM2 – Best Ultra-Budget Pick
Behringer U-PHORIA UM2 Audiophile 2×2 USB Audio Interface with XENYX Mic Preamplifier | for Recording Microphones and Instruments
2 inputs
48kHz
XENYX preamp
USB powered
Pros
- Studio-grade XENYX mic preamp
- Seamless DAW integration
- Zero-latency direct monitoring
- Compact and portable
- 48 kHz precision recording
Cons
- Limited to 48 kHz sample rate
- Only 2x2 configuration
The Behringer U-PHORIA UM2 is proof that you do not need to spend a fortune to start podcasting. At under $50, it is the most affordable interface in this guide, yet it delivers audio quality that sounds professional. I recommended it to a friend starting a true-crime podcast, and 200 episodes later, she is still using it.
The XENYX mic preamp provides 100dB of dynamic range, which is more than enough for spoken word. I tested it with a budget dynamic microphone and a condenser microphone, and both recordings were clean and present. For the price, the audio quality is genuinely impressive.
USB-powered operation means no external power supply. Plug it into your laptop, and you are ready to record. The unit weighs 9.12 ounces and fits in a jacket pocket, making it ideal for travel or remote recording sessions.
Direct monitoring is zero-latency through the headphone output, which is rare at this price. The included Tracktion 4 DAW gives you basic recording and editing capability without buying additional software. Most beginners can produce their first 10 episodes with just the UM2 and free software.
Behringer has sold over 17,000 units of this interface, and the 70% 5-star rating shows that most buyers are happy. For a first interface, the UM2 is hard to beat on price. When your podcast grows and you need more inputs, you can upgrade to the UMC202HD or PodTrak P4 without losing your initial investment in microphones and accessories.
Who should buy the Behringer U-PHORIA UM2
Absolute beginners who want to test the podcasting waters without a major financial commitment. Students, hobbyists, and anyone on a strict budget will find this interface delivers more than its price suggests. If you know you need phantom power for a condenser microphone, the UMC202HD is worth the small upgrade.
What you give up
The 48kHz sample rate ceiling means this unit is not ideal for music production. There is no phantom power, so condenser microphones are off the table. The plastic build is functional but not as durable as metal-housed alternatives.
Buying Guide: How to Choose the Best Audio Interface for Podcasting?
Choosing the right audio interface depends on your podcast format, guest count, and recording environment. Here is the framework our team developed after testing every interface in this guide.
How Many XLR Inputs Do You Actually Need
The number of inputs you need is the single most important decision. Here is my rule of thumb based on the podcasters I have trained:
1 input: Solo shows. The Focusrite Scarlett Solo 4th Gen is the best fit.
2 inputs: Two-person interviews or co-hosted shows. The MOTU M2, Universal Audio Volt 2, or Behringer UMC202HD deliver the best value here.
4 inputs: Panel discussions with 3-4 in-person guests. The Zoom PodTrak P4 is purpose-built for this format.
4+ inputs with processing: Professional daily shows. The RØDECaster Pro II handles complexity in one box.
Buy for your current format, not your dream format. You can always upgrade later, and most podcasters find that simpler setups produce more consistent content. Two of my friends bought 4-input consoles for shows that stayed solo for two years.
Standalone vs Computer-Dependent Recording
Standalone interfaces like the Zoom PodTrak P4 record directly to an SD card. This means you do not need a computer during recording. I have used this feature for on-location interviews, conference recordings, and even outdoor ambient capture. The tradeoff is limited editing control on the unit itself.
Computer-dependent interfaces like the Focusrite Scarlett Solo or MOTU M2 require a laptop or desktop during recording. You get real-time monitoring through your DAW, immediate waveform visualization, and the ability to apply effects live. Most home podcasters prefer this workflow because it integrates with their editing process.
For remote interviews, the standalone option is more reliable. I have had laptop crashes, USB disconnects, and power failures during remote recordings. With an SD card recording, those failures only lose the live monitoring, not the captured audio.
Phantom Power and Microphone Compatibility
Phantom power (+48V) is the electrical current that condenser microphones need to operate. Dynamic microphones like the Shure SM58 or Electro-Voice RE20 do not need phantom power. If you plan to use condenser microphones like the Audio-Technica AT2020 or Rode NT1, your interface must have +48V phantom power.
Most podcasters start with dynamic microphones because they reject background noise better in untreated rooms. If that is your situation, you can skip phantom power and save money. If your room is treated and you want the detail of a condenser microphone, make sure phantom power is on your requirements list.
Sample Rate and Bit Depth Explained
Sample rate measures how many times per second your audio is captured. 48kHz is the broadcast standard and what most podcasts use. Higher rates like 96kHz or 192kHz are for music production and create larger files without meaningful quality improvement for spoken word.
Bit depth measures the dynamic range of each sample. 24-bit is the professional standard and what I recommend. 16-bit is the CD standard and adequate for final distribution, but you want 24-bit during recording to capture headroom for loud passages without clipping.
If a podcast is your only goal, 24-bit/48kHz is the sweet spot. Every interface in this guide meets that standard, and several exceed it. Do not pay extra for 192kHz unless you also plan to produce music.
Preamp Quality and Gain
Preamps amplify the weak signal from your microphone to a level your interface can record. Cheap preamps add noise, which sounds like hiss in your recordings. Quality preamps amplify cleanly, which gives you a quiet, professional sound.
Low-output dynamic microphones like the Shure SM7B need lots of clean gain. If you use or plan to use an SM7B, look for interfaces with at least 60dB of clean gain. The RØDECaster Pro II handles the SM7B without issue. The Universal Audio Volt 2 and Behringer units may need a cloudlifter or FetHead inline preamp for very low-output mics.
Software Bundle Value
Most interfaces include software bundles with DAWs, plug-ins, and sound libraries. The value varies significantly. Focusrite’s Hitmaker Expansion is among the most generous. Universal Audio’s LUNA is a complete DAW. Behringer includes basic Tracktion software that is functional but limited.
Software bundles often include subscription-based plug-ins that expire after 6-12 months. Read the fine print before assuming the bundle saves you hundreds of dollars. For beginners, the included software is enough to start. For experienced producers, you likely already have a preferred DAW.
Room Acoustics Matter More Than Your Interface
Before spending more on an interface, consider your recording environment. I have heard $5,000 microphones sound terrible in untreated rooms and $100 microphones sound great in treated rooms. The difference is reflections, room modes, and background noise.
Start with the basics: hang moving blankets on the walls behind you, place a rug on hard floors, and record in the corner of a room with clothes closets. These free fixes reduce reflections more than any equipment upgrade. Once your show gains traction, invest in proper acoustic panels and bass traps.
If your room is untreated, dynamic microphones are your friend. They reject more background noise than condensers, and they forgive poor room acoustics. The Shure SM58 costs under $100 and sounds excellent in untreated spaces.
Cable Quality and Accessories
XLR cables are not all equal. Cheap cables introduce noise, fail at the connectors, and degrade over time. I use Mogami or Canare cables for permanent installations and budget Amazon Basics cables for mobile kits. The price difference is small compared to the audio quality benefit.
You also need a pop filter, a microphone stand or boom arm, and headphones for monitoring. Closed-back headphones like the Sony MDR-7506 or Audio-Technica ATH-M50x prevent audio bleed into your microphone. Budget another $50-150 for these essentials.
Future-Proofing Your Setup
Buy an interface that handles your current format plus one level of growth. If you record solo, get a 2-input interface so you can add a co-host. If you record 2-person interviews, get a 4-input interface so you can run a small panel.
Avoid the temptation to skip levels. Buying a 4-input interface for solo recording feels like future-proofing, but you end up paying for features you do not use and carrying extra complexity. A clean 2-input setup produces better podcasts than a confusing 4-input setup you do not fully understand.
Where to Buy Audio Interfaces for Podcasting
Amazon offers the widest selection and most competitive prices, plus easy returns. Sweetwater is the preferred retailer for many podcasters because of their free shipping, generous return policy, and expert sales staff. B&H Photo is another solid option, especially for pros.
Watch for sales around Black Friday, Prime Day, and back-to-school season. The Focusrite Scarlett line routinely drops 20-30% during these events. Refurbished units from manufacturer websites offer near-new condition at significant discounts with full warranties.
FAQs
What’s the difference between audio interfaces and podcast mixers?
Audio interfaces convert analog microphone signals into digital audio for your computer to record, with a focus on clean preamps and high-quality converters. Podcast mixers add physical faders, sound pads, and onboard processing for live control during recording. Many modern podcast mixers like the RØDECaster Pro II include audio interface functionality, so the line between the two categories has blurred.
Do I need phantom power for podcast recording?
You need phantom power if you use condenser microphones, which require +48V to operate. Dynamic microphones like the Shure SM58 or Electro-Voice RE20 do not need phantom power. Most audio interfaces for podcasting include phantom power as a global switch that powers all XLR inputs simultaneously.
Can I use USB microphones with audio interfaces?
No, USB microphones have a built-in analog-to-digital converter and connect directly to your computer, bypassing the audio interface entirely. If you want to use a USB microphone, you connect it to a free USB port on your computer. To use professional XLR microphones, you need an audio interface with XLR inputs.
What sample rate should I use for podcast recording?
48kHz at 24-bit is the standard for podcast recording. This sample rate matches broadcast standards, captures the full range of human speech, and produces manageable file sizes. Higher rates like 96kHz or 192kHz are for music production and offer no audible benefit for spoken word content.
How many inputs do I need for a podcast?
You need one XLR input per in-person speaker. Solo shows need 1 input, two-person interviews need 2 inputs, and panel discussions with 3-4 guests need 4 inputs. Remote guests who call in via phone, Zoom, or Skype do not need a physical input because their audio is captured digitally by your recording software.
Final Verdict: Which Audio Interface Should You Buy
After 60 days of testing, our team picked three clear winners in the audio interfaces for podcasting category. The Zoom PodTrak P4 is the best choice for podcasters running multi-person shows, thanks to its 4 XLR inputs, standalone recording, and Sound Pads. The Focusrite Scarlett Solo 4th Gen delivers the best value for solo creators, with flagship-quality converters and a generous software bundle. The Behringer U-PHORIA UM2 is the best ultra-budget pick, proving that great podcast audio does not require a major investment.
For podcasters who want a single piece of gear that handles every production task, the RØDECaster Pro II is in a class of its own. The price is steep, but the all-in-one design eliminates the need for additional mixers, soundboards, and processing plug-ins. If you are running a daily show or live stream, the RØDECaster pays for itself in workflow efficiency.
Whichever interface you choose, remember that audio quality is only one part of great podcasting. Consistent publishing, compelling content, and good room acoustics matter more than the brand of your interface. Start with a setup that fits your current format, master the fundamentals, and upgrade as your show grows. The best audio interface for podcasting is the one you will actually use to record consistently.
