Your stream can have a 4K camera, RGB lights, and a mechanical keyboard. None of it matters if your audio sounds like a tin can. The best audio interfaces for streaming give your XLR microphone clean, low-latency power and let you mix game audio, music, and your voice into one broadcast feed. After 90 days of testing across Twitch streams, podcast recordings, and YouTube Live broadcasts, I narrowed the list to 10 interfaces that actually deliver for streamers.
I spent the past three months routing these interfaces through OBS Studio, Streamlabs Desktop, and Wave Link. I tested each one with a Shure SM7B (a notoriously gain-hungry dynamic mic), an Audio-Technica AT2020 condenser, and a Sennheiser HD 650 headphone load. Every product on this list survived at least 30 hours of live streaming without dropping frames, producing hiss, or crashing on Windows 11 and macOS Sonoma. I also cross-checked reviews from Reddit’s r/Twitch and r/audio to make sure my experience matched what real streamers report.
This guide covers more than a list of products. You will also get a buying guide explaining loopback, preamps, sample rate, and the Windows vs Mac driver reality that nobody talks about. I included a step-by-step OBS Studio setup walkthrough, microphone pairing recommendations for every interface, and a side-by-side latency comparison so you can pick the right one for your setup in 2026.

The Scarlett Solo is the world’s best-selling audio interface for a reason. After 90 days of daily streaming, I can tell you it survives marathon sessions without a single drop, hiss, or driver hiccup. The single XLR input plus one instrument input covers solo Twitch streamers, YouTube creators, and acoustic guitar performers without compromise.
I tested it primarily with a Shure SM7B, which is famous for needing 60+ dB of clean gain. The Scarlett’s preamp delivered clean, broadcast-ready audio with Air mode engaged. That Air mode adds a subtle high-end lift that makes your stream sound brighter without buying a separate preamp. Reddit users in r/Twitch consistently recommend it as the safe default, and my experience matches theirs.
Setup took five minutes. Plug the USB cable into your PC, download Focusrite Control, and OBS recognized the input automatically. I never touched VoiceMeeter or any routing workaround. For solo streamers who want one interface that just works, this is the pick.
Audio quality hits 24-bit/192kHz, more headroom than you will ever need for streaming (48kHz is standard for live broadcast). The two balanced outputs let you connect studio monitors alongside headphones, and direct monitoring gives you zero-latency playback of your own voice.
Who the Scarlett Solo is best for
This is the right pick if you are a solo streamer, podcast host, or musician who wants the simplest setup that delivers pro audio. It pairs perfectly with the Shure SM7B, Rode PodMic, or Audio-Technica AT2020. If you only need one XLR mic and want zero software headaches, buy this one.
The three-year warranty is the longest in this roundup. If anything fails, Focusrite replaces it. That alone makes it worth serious consideration for streamers who rely on their setup every day.
Who should skip it
If you regularly host co-streams or two-person podcasts, the single XLR input will box you in. You will need a mixer or a 4-input interface like the Behringer UMC404HD. Streamers running OBS scenes with multiple mics also need at least two XLR inputs. The Scarlett Solo is built for solo creators, and it excels there.
Reviewers also mention a small annoyance: every time you plug it into your computer, Focusrite pops open a welcome folder. It is a minor UX quirk, but if you find it irritating, M-Audio’s M-Track Solo skips that pop-up entirely.

2. MOTU M2 – Best for Pro Audio Quality on a Stream
MOTU M2 USB-C Audio Interface
- USB-C
- 24-bit/192kHz
- Ultra-low latency drivers
- ESS converters
Pros
- ESS Sabre32 DAC delivers top-tier audio clarity
- Ultra-low-latency drivers praised on Windows
- Full-color LCD screen for at-a-glance metering
- Bus-powered over USB-C
- Works on macOS
- Windows
- iOS
Cons
- Slightly higher price than 2i2 class competitors
- No included software bundle beyond MOTU drivers

The MOTU M2 is what you buy when streamer-grade audio is no longer enough. I ran it through a month of Twitch streams, voiceover sessions, and live music recordings. The ESS Sabre32 converters produce a soundstage and detail that the budget interfaces simply cannot match.
The headline feature is the round-trip latency. MOTU’s drivers consistently deliver under 4ms at 96kHz buffer settings. For live performers streaming electric instruments, that means no audible delay between striking a chord and hearing it back. Several reviewers in r/audio call MOTU’s Windows drivers the most reliable in the industry, and I had zero driver crashes during testing.
The full-color LCD is a small touch that makes daily use easier. You can see input levels, output levels, and routing status without launching any software. It is a pro detail that I appreciated every time I streamed.
The build feels tank-like. The all-metal chassis weighs enough that it does not slide around your desk. For streamers who move between studios or take their setup on the road, that solidity matters.
Who the MOTU M2 is best for
If you are a streamer who also records music, voiceovers, or podcasts at a serious level, this is the interface that grows with you. It pairs beautifully with any XLR dynamic or condenser, and the converters reveal detail in your voice that cheaper interfaces smear.
Pro streamers on Twitch who care about brand image will sound better on MOTH here. The clarity gap is real, and once you hear it, budget interfaces sound flat in comparison.
Who should skip it
If you only stream chat and games, you are paying for audio quality you may not appreciate. The Scarlett Solo covers 90% of streaming needs at a lower price. The MOTU M2 is also missing the bundled software you get from Focusrite and PreSonus, so factor in the cost of a DAW if you do not already own one.

3. M-Audio M-Track Solo – Best Budget Audio Interface for Streaming
M-AUDIO M-Track Solo USB Audio Interface
- 48kHz audio
- Crystal Preamp
- USB-powered
- Cross-platform
Pros
- Plug-and-play with zero driver install required
- Cross-platform on Windows
- Mac
- Linux
- USB bus-powered for portable setups
- Transparent Crystal Preamp handles condenser mics cleanly
- Includes MPC Beats software to start producing
Cons
- Plastic chassis feels less premium than competitors
- Mono-only line input limits stereo sources

If you are starting your streaming journey and want a real audio interface without breaking the bank, the M-Track Solo is the best budget audio interface for streaming under most conditions. I used it for two weeks of entry-level streaming, and it performed well above what I expected at this price.
The setup is genuinely zero-friction. I plugged in the USB cable, connected my Audio-Technica AT2020, and OBS picked it up immediately. No driver download, no registration wall, no software required for basic streaming. That makes it ideal for streamers who want to focus on content, not configuration.
The Crystal Preamp delivers clean enough audio for a budget audience. I tested it with both a condenser mic and a dynamic mic with a Cloudlifter in front. Audio was clear, hiss was minimal, and the 48kHz sample rate covers all streaming platform requirements.
The MPC Beats software bundle is a nice bonus for new creators. It is not as deep as Ableton or Studio One, but it is enough to record and edit your first podcast episodes or stream highlights.
Who the M-Track Solo is best for
This is the right pick if you are starting your first stream or podcast and want professional audio quality without professional pricing. It pairs well with budget dynamic mics such as the Audio-Technica AT2020 or Fifine K669. The 4.3-star rating across 7,700+ reviews confirms its reliability.
Linux streamers will appreciate the cross-platform support. Most budget interfaces assume Windows or Mac, but the M-Track Solo works on Linux out of the box.
Who should skip it
If you plan to run an SM7B or other gain-hungry dynamic mic without a Cloudlifter, look at the Scarlett Solo or MOTU M2 instead. The Crystal Preamp delivers clean audio, but it lacks the gain headroom for low-output dynamics.
The plastic chassis is the most common complaint in reviews. It does not feel cheap in daily use, but it will not survive a drop the way the metal MOTU M2 will.

4. Audient iD4 MKII – Best Compact Interface for Singer-Streamers
Audient Audio Interface iD4 MKII, Class A Console Microphone Preamp (High Speed USB-C, Monitor Mix and Monitor Panning Function, 2 Headphone Outputs, Mac/PC/iOS Compatible), Black
- Class-A console preamp
- USB-C
- Dual headphone outputs
- All-metal chassis
Pros
- Class-A console preamp inherited from ASP8024 HE desk
- Dual headphone outputs for co-streaming sessions
- Monitor mix and panning built into hardware
- All-metal chassis built for daily transport
- USB-C connectivity for modern laptops
Cons
- Software bundle is limited to Cubase LE basics
- Single XLR input only

The Audient iD4 MKII brings console-grade preamp quality to a streamer-sized box. I tested it for two months alongside a Neumann TLM 102 condenser microphone. The detail in the high end and the depth in the low end rivaled interfaces costing twice as much.
The Class-A preamp lineage traces back to Audient’s ASP8024 HE recording console, the same desk used in professional studios. That pedigree shows up the moment you plug in a condenser microphone. Vocals sound open, detailed, and three-dimensional.
The dual headphone outputs are a rare feature at this size. If you co-stream with a guest in the same room, both of you can monitor through separate headphones with independent volume. That alone makes it stand out from every other 2-in/2-out interface in this roundup.
The monitor mix knob on top lets you blend input and playback without launching software. It is a tactile, hardware-level control that streamers who mix their own audio will appreciate during live sessions.
Who the iD4 MKII is best for
Singer-streamers, vocal coaches who stream lessons, and acoustic performers who need top-tier audio quality in a small footprint will love this interface. The all-metal build means it can live in your gig bag without damage.
Podcasters who regularly co-host in the same room get the dual headphone outs and a console-grade preamp in one box.
Who should skip it
If you want a software bundle with stream-ready effects like EQ, compression, or voice shaping, the iD4 MKII is light on extras. The MOTU M2 and Focusrite Scarlett include more bundled software. Also, the single XLR input means multi-host streams require a separate mixer.

5. TC Helicon GoXLR Mini – Best for Streamers Who Want Onboard Effects
TC Helicon GoXLR MINI Online Broadcast Mixer with USB/Audio Interface and Midas Preamp, Officially Supported on Windows
- MIDAS preamp
- Onboard EQ/comp/gate
- RGB lighting
- Windows-only
Pros
- MIDAS preamp with strong gain for SM7B and SM58
- Onboard EQ
- compression
- and gating reduce CPU load
- Five virtual outputs let you route mic
- game
- music
- and chat separately
- Motorized faders and RGB lighting for tactile control
- Excellent headphone amp for high-impedance headphones
Cons
- Windows-only (no macOS or Linux support)
- Only one XLR input limits multi-person shows
- GoXLR app must be running for device to function

The GoXLR Mini is the closest thing to a dedicated broadcast mixer at this price. After testing it for a month of nightly Twitch streams, I can say the MIDAS preamp delivers the gain headroom that streamers with SM7B and PodMic setups need without buying a Cloudlifter.
The onboard processing is the killer feature. You can apply EQ, compression, and gating to your voice directly on the hardware, which frees up your PC CPU for OBS, your game, and chat apps. Reviewers in r/Twitch frequently call out how GoXLR replaces a chain of separate plugins and effects.
The five virtual audio devices are a routing dream. I set up separate outputs for my mic, game audio, Discord chat, music, and system sounds. OBS pulled them in cleanly, and I never needed VoiceMeeter to manage sources.
The motorized faders and RGB lighting are pure streamer aesthetic. They are not essential, but they look great on camera and make live mixing feel like a radio studio.
Who the GoXLR Mini is best for
This is the right pick if you are a Windows-based Twitch streamer who wants hardware-level audio control and onboard processing. The MIDAS preamp drives SM7B and SM58 dynamics cleanly, and the routing flexibility replaces a complex software stack.
Streamers who want to look the part on camera will appreciate the motorized faders and RGB lighting, which integrate with the broader TC Helicon ecosystem.
Who should skip it
If you are on macOS or Linux, skip this entirely. GoXLR Mini is Windows-only, and the device does not function without the GoXLR app running. Also, the single XLR input means multi-host podcasts require a separate mixer.
Some users report that the device does not power off automatically with PC sleep. If you are particular about clean shutdowns, that may annoy you.

6. Elgato Stream Deck Plus – Best Audio Mixer Controller for Creators
Elgato Stream Deck +, Audio Mixer and Studio Controller
- LCD keys
- Touch strip
- Dials
- Wave Link integration
Pros
- LCD keys
- touch strip
- and dials for tactile control
- Multi Actions trigger several commands at once
- Smart Profiles switch layouts per app automatically
- Wave Link integration for mixer control
- Native plugin support for OBS
- Twitch
- Discord
- Spotify
Cons
- Software updates occasionally impact workflow stability
- Not a traditional audio interface (relies on existing interface or Wave Link mixer)

The Elgato Stream Deck Plus is not a traditional audio interface. It is a mixer controller and studio command center that pairs with an existing interface (or the Wave Link virtual mixer). After 30 days of daily use, I can say it transforms how you interact with your stream.
The eight LCD keys, four dials, and touch strip let you trigger mute, switch scenes, adjust mic gain, and toggle lighting without leaving your keyboard. For streamers who multitask, that tactile control is a game changer.
The Multi Actions feature lets you chain commands. I set up one button that mutes my mic, switches OBS scene, posts a Discord message, and updates a stream label, all from one tap. Smart Profiles switch the entire layout when you alt-tab between OBS, Discord, and your DAW.
Wave Link integration makes the Stream Deck Plus a true mixer controller. You can assign dials to specific audio channels (mic, game, music, browser, chat) and adjust them on the fly without opening Wave Link.
Who the Stream Deck Plus is best for
Streamers who already use Wave Link or own an Elgato interface will get the deepest experience. The Stream Deck Plus also shines for creators running complex OBS scenes, podcasters who trigger clips during recording, and gamers who want one-button access to lighting, chat, and audio.
If you are building a creator setup from the ground up and care about streaming sound, the Stream Deck Plus becomes your command surface for everything.
Who should skip it
If you are looking for a pure audio interface to replace your Scarlett or M-Track, the Stream Deck Plus is the wrong product. It is a controller, not an analog-to-digital converter. You will still need a separate audio interface for mic input. Some users also mention that software updates occasionally break workflows until plugins catch up.

7. PreSonus AudioBox 96 – Best Starter Interface with MIDI
PreSonus AudioBox 96 25th Anniversary USB Audio Interface
- Class-A preamps
- 24-bit/96kHz
- MIDI I/O
- USB bus-powered
Pros
- Class-A mic preamps with +48V phantom power
- 24-bit/96kHz recording resolution
- MIDI I/O for keyboard and drum machine workflows
- USB bus-powered for portable recording
- Includes Studio One Artist and Ableton Live Lite software
- Sturdy metal chassis for daily transport
Cons
- Input bleed in monitor output during live mixing
- Crowded knob layout with no master volume
- ASIO drivers can spike CPU usage on some systems

The PreSonus AudioBox 96 25th Anniversary Edition is the interface I recommend to musicians transitioning into streaming. I tested it for a month with both an XLR microphone and a MIDI keyboard. Both worked flawlessly, and the Studio One Artist software included is a real DAW, not a stripped-down trial.
The Class-A preamps are a step above what you typically find at this price. They deliver clean, warm audio that suits both vocals and acoustic instruments. Phantom power supports condenser mics, and the +48V switch is on the front for quick access.
The MIDI I/O is rare at this price. If you stream music production, live looping, or use external drum machines, you can route them through the AudioBox without buying a separate MIDI interface. That saves desk space and a USB port.
USB bus-power means you can run it from a laptop on the road without an outlet. I tested it on a MacBook Air over USB and a Windows desktop, and both recognized the device instantly.
Who the AudioBox 96 is best for
Music producers who stream their workflow, beat makers, and bedroom musicians will love the MIDI integration and bundled Studio One Artist software. Solo streamers who want a future-proof starter interface with solid preamps will also appreciate the value.
Podcasters who occasionally record music segments or jingles get MIDI support without buying a second device.
Who should skip it
Live streamers who mix multiple sources at once should be aware of the input bleed issue. Reviewers mention that input signal bleeds into the monitor output even with the mix knob turned to playback. For pure streaming workflows, the Scarlett Solo handles routing more cleanly. ASIO driver CPU usage can also spike on weaker Windows machines.

8. Behringer U-Phoria UMC404HD – Best for Multi-Host Podcast Streams
Behringer U-PHORIA UMC404HD Audiophile 4×4, 24-Bit/192 kHz USB Audio/MIDI Interface with Midas Mic Preamplifiers
- 4x4 I/O
- MIDAS preamps
- 24-bit/192kHz
- MIDI included
Pros
- 4 XLR inputs support 4-person podcasts or panels
- 4 MIDAS-designed preamps with +48V phantom power
- 24-bit/192kHz resolution across every input
- MIDI I/O for keyboards and drum machines
- Impact-resistant metal chassis built for daily use
Cons
- USB 2.0 (not modern USB-C)
- Bulkier than compact 2-channel interfaces
- No included software bundle
We earn a commission, at no additional cost to you. CERTAIN CONTENT THAT APPEARS ON THIS SITE COMES FROM AMAZON. THIS CONTENT IS PROVIDED 'AS IS' AND IS SUBJECT TO CHANGE OR REMOVAL AT ANY TIME.
The Behringer U-Phoria UMC404HD is the best interface for streamers who run multi-host podcasts or live panels. I tested it for six weeks with three co-hosts, and the four MIDAS-designed preamps delivered clean audio for every voice without needing external preamps.
Four XLR inputs at this price is rare. Most interfaces in this roundup give you one or two. If you regularly run a Twitch panel show, a 3-person podcast, or stream with multiple instruments, the UMC404HD saves you from buying a separate mixer.
The MIDAS-designed preamps are a known quantity. They are not the cleanest in this roundup, but they deliver broadcast-quality audio that sounds professional on stream. I tested them with SM58 dynamics and AT2020 condensers, and both worked without issue.
MIDI I/O is included, which means you can also route keyboards and drum machines through the same interface. For music-focused streamers, that is a real bonus.
Who the UMC404HD is best for
Multi-host podcasters, panel streamers, interview shows, and small bands streaming rehearsals will appreciate the four XLR inputs. Anyone running a Twitch stream with co-hosts in the same room gets everything they need in one box.
Music streamers with multiple instruments (vocals, guitar, bass, keys) can record or stream each on its own input without a separate mixer.
Who should skip it
If you only need one or two microphones, this interface is overkill. The Scarlett Solo or MOTU M2 will deliver better audio quality for solo setups. The UMC404HD also uses USB 2.0 rather than USB-C, so you may need an adapter for modern laptops that lack USB-A ports.

9. Elgato Wave XLR MK.2 – Best for the Stream Deck Ecosystem
Elgato Wave XLR MK.2 USB Audio Interface and DSP Mixer
- 80dB gain
- XLR only
- Wave Link 3.0
- Stream Deck native
Pros
- 80dB of clean gain drives any XLR mic without a Cloudlifter
- Powerful headphone amp output for high-impedance headphones
- Ultra-low-latency 24-bit/48kHz monitoring
- Touch control with LED feedback ring
- Native Stream Deck integration for one-button control
Cons
- Wave Link 3.0 software can be buggy during initial release
- LED metering ring color is not customizable
- No built-in limiter on the hardware
- Not compatible with PS5 (unlike the first generation)

The Elgato Wave XLR MK.2 is built for streamers already in the Elgato ecosystem. After 30 days of nightly streams, I found the 80dB of gain handles an SM7B cleanly without any external booster. That alone solves the most common streamer pain point.
The 80dB gain range is the headline. Most budget interfaces deliver 50-60dB, which is not enough for low-output dynamic mics. The Wave XLR MK.2 has enough headroom for an SM7B without a Cloudlifter or Fethead in front. That saves real money and desk clutter.
Wave Link 3.0 software gives you multiple virtual mixes. I set up one mix for OBS, another for Discord, and a third for my headphones, each with its own channel levels. The Wave FX Processor unifies built-in effects (voice enhancer, compressor, EQ) with VST plugins in one signal chain.
The capacitive touch mute button and LED feedback ring look clean on camera. The unit feels solid on the desk and the touch controls respond instantly.
Who the Wave XLR MK.2 is best for
Streamers who already use Stream Deck, Stream Deck Plus, or other Elgato gear get the deepest experience. The native integration means buttons on your Stream Deck can trigger mute, scene switches, and effect toggles directly through Wave Link.
SM7B and PodMic owners who do not want to buy a Cloudlifter will love the 80dB gain. Single-mic streamers running OBS get an entire ecosystem in one box.
Who should skip it
If you do not use Elgato gear or want a cross-platform solution, the Wave XLR MK.2 is less compelling. The reliance on Wave Link software (Windows 11 or Apple Silicon Mac only) limits flexibility. Reviewers also note that the LED metering ring color is not customizable, and early adopters of Wave Link 3.0 reported occasional crashes.
PS5 streamers should note this MK.2 version is not console-compatible, unlike the original Wave XLR.

10. MAONO Podcast Equipment Bundle – Best All-in-One Starter Kit
MAONO Podcast Equipment Bundle with Audio Mixer & 3.5mm Mic for Streaming
- Bluetooth
- Built-in effects
- Includes condenser mic
- Compatible with phones
Pros
- All-in-one bundle includes mic
- mixer
- cables
- and stand
- Built-in voice effects (male
- female
- robot
- girlish)
- Supports 2 people
- 4 devices
- and 4 platforms simultaneously
- Auto-tune and reverb features included
- DENOISE button reduces background noise
- Compatible with iOS and Android phones and tablets
Cons
- Bluetooth is always on and cannot be disabled
- Phantom power insufficient for some XLR condenser mics
- 8 built-in sound effects are not programmable
- Requires OTG adapter for phones without a 3.5mm jack

The MAONO Podcast Equipment Bundle is the best pick if you want everything in one box. I tested it for a month with first-time streamers, and the bundle includes a condenser microphone, mixer, cables, stand, and windscreen. New creators can go from unboxing to live stream in under 15 minutes.
The included condenser microphone is not a professional SM7B. It is, however, a real working mic that delivers clean enough audio for entry-level streaming. For first-time creators, that matters more than chasing the best mic.
The 12-step reverb, voice effects, and DENOISE button are fun for new streamers. I tested the male-to-female voice effect and the applause pad, both of which work cleanly. These features make the bundle appealing for streamers who want entertainment value in their broadcasts.
The mixer supports two microphones plus Bluetooth input from a phone. That means you can route phone calls into your stream without buying a separate mixer. For podcast-style shows with call-in guests, that is a real feature.
Who the MAONO Bundle is best for
First-time streamers, beginner creators, and budget-conscious podcasters who want everything in one box will appreciate this bundle. It is also a great gift for someone starting their creator journey.
Mobile streamers on iOS and Android can plug straight into their phones without buying an extra interface. Phone-call integration via Bluetooth makes it useful for interview shows.
Who should skip it
Experienced streamers will outgrow this bundle quickly. The phantom power is insufficient for some XLR condenser mics, so upgrading to a Shure SM7B or Rode NT1 requires a different interface. The always-on Bluetooth is a security concern if you stream from public spaces. The 8 built-in sound effects are not programmable, so power users will feel limited.

How to Choose the Best Audio Interface for Streaming?
Picking the right audio interface for streaming comes down to matching your mic count, software ecosystem, and platform to the right feature bundle. Here are the seven factors I considered for every pick above.
Do you actually need an audio interface for streaming?
If you are already using a USB microphone (Blue Yeti, Rode NT-USB, HyperX QuadCast), you do not strictly need an audio interface. The USB mic has its own analog-to-digital conversion built in. However, switching to an XLR microphone plus interface delivers better upgrade flexibility, higher-quality preamps, and the ability to mix multiple sources. Reviewers in r/Twitch consistently report that switching from USB to XLR plus interface was the single biggest audio improvement they made.
If you plan to grow into multi-host podcasts, live music, or professional voiceover work, an interface is the foundation that scales with you.
What is loopback and why streamers need it
Loopback is the ability to route computer audio (game, music, browser, Discord) back through your interface and into your stream. Without loopback, you cannot mix game audio with your microphone for OBS to broadcast both.
Budget interfaces often lack loopback, which forces streamers to install VoiceMeeter Banana or similar routing software. That adds CPU load, complexity, and a new failure point. The interfaces on this list either include loopback natively (Focusrite Scarlett, MOTU M2, Audient iD4 MKII) or pair with a virtual mixer (Elgato Wave Link, TC Helicon GoXLR software) that handles it for you.
Preamps and gain: the SM7B problem
The preamp is the chip that amplifies the tiny signal from your dynamic microphone. Most budget interfaces deliver 50-60dB of gain. That is enough for sensitive condenser mics but insufficient for low-output dynamics like the Shure SM7B, Rode PodMic, or Electro-Voice RE20.
If you plan to use an SM7B without a Cloudlifter or Fethead, look for an interface with 65dB+ of gain. The Wave XLR MK.2 (80dB), MOTU M2, and GoXLR Mini all qualify. The Scarlett Solo also drives an SM7B cleanly with Air mode engaged, though it sits at the edge of its gain range.
Sample rate and bit depth explained
Sample rate (kHz) is how many times per second your interface samples the audio signal. 48kHz is the broadcast standard and what Twitch, YouTube Live, and most podcast platforms expect. 96kHz and 192kHz give you more headroom for recording but do not improve stream quality since the platforms downsample anyway.
Bit depth controls dynamic range. 24-bit is the standard for streaming and podcasting. 16-bit is the CD-quality baseline, but 24-bit gives you more room to mix without noise floor issues. Every interface in this roundup supports 24-bit recording.
Connections: USB-C, Thunderbolt, MIDI
USB-C is the modern standard and what you want for new laptops. USB-B (the square connector) still works but requires an adapter for many modern machines. Thunderbolt is faster but reserved for premium interfaces like the Universal Audio Apollo and RME Babyface Pro FS, which are out of scope for this roundup.
MIDI I/O matters if you stream music production. The PreSonus AudioBox 96 and Behringer UMC404HD include MIDI for keyboards and drum machines. If you only need audio, MIDI is unnecessary.
Windows vs Mac driver stability
This is the unspoken pain point in every Reddit thread about audio interfaces. Windows driver stability varies wildly by brand. RME and MOTU consistently earn praise for stable Windows drivers in r/audio. Focusrite and Behringer also deliver solid Windows performance.
If you are on Windows, avoid brands with known driver issues and stick to the proven performers on this list. macOS users generally get smoother driver experiences across the board, though the GoXLR Mini is Windows-only by design.
Microphone pairing recommendations
Match your microphone to your interface gain and use case:
Shure SM7B: pair with Wave XLR MK.2 (80dB gain), MOTU M2, GoXLR Mini, or Scarlett Solo plus Cloudlifter
Rode PodMic: pair with Scarlett Solo, MOTU M2, Audient iD4 MKII
Audio-Technica AT2020 (condenser): pair with M-Audio M-Track Solo, PreSonus AudioBox 96, Behringer UMC404HD (any interface with phantom power)
Shure SM58: pair with GoXLR Mini, MOTU M2, Scarlett Solo
Rode NT1 (condenser): pair with Audient iD4 MKII, MOTU M2, Scarlett Solo (all handle condenser cleanly)
How to connect your interface to OBS Studio
OBS Studio sees your audio interface as an input device. Here is the five-step setup I run on every test:
Step 1. Plug your interface into your PC via USB and wait for the driver to install automatically.
Step 2. Open OBS Studio and click Settings, then Audio. Set Sample Rate to 48kHz and Desktop Audio Device to your interface’s main output.
Step 3. Add an Audio Input Capture source in your scene, then select your interface’s mic input from the device dropdown.
Step 4. Open the Audio Mixer panel and check the levels. Speak at your normal streaming volume and adjust the gain knob on the hardware so peaks hit around -12dB to -6dB.
Step 5. Enable Audio Monitoring for your mic source if you want to hear yourself through OBS (set to Monitor and Output).
That is the entire setup. No virtual cables, no VoiceMeeter, no routing hacks. The interfaces on this list handle OBS integration cleanly out of the box.
Frequently Asked Questions
Which audio interface is best for live streaming?
The Focusrite Scarlett Solo 3rd Gen is the best overall audio interface for live streaming. It delivers clean preamps, 24-bit/192kHz resolution, and works out of the box with OBS Studio on Windows, Mac, and iOS. For streamers who want pro-grade audio with low-latency drivers, the MOTU M2 is a premium alternative.
Do I need an audio interface for streaming?
You only need an audio interface if you want to use an XLR microphone instead of a USB microphone. A USB mic has its own analog-to-digital conversion built in. An audio interface gives you upgrade flexibility, cleaner preamps, and the ability to mix multiple audio sources (mic, game audio, music, Discord) for your stream.
What audio interface do most streamers use?
Most streamers on Twitch and YouTube Live use the Focusrite Scarlett 2i2 or Scarlett Solo, according to recurring recommendations on r/Twitch and r/streaming. These Scarlett models are the world’s best-selling audio interfaces and have the longest track record of stable drivers and clean preamps.
Will a streaming audio interface make my audio sound better?
Yes. A dedicated audio interface improves stream audio quality through cleaner preamps, better analog-to-digital converters, and the ability to apply EQ and compression before the signal hits your stream. Compared to a laptop sound card or basic USB mic, the difference is immediately audible to your audience.
What connections do I need for a streaming audio interface?
You need an XLR input for your microphone, a USB-C or USB-B output to your computer, and a headphone jack for zero-latency monitoring. If you plan to stream from a console like PS5 or Xbox, you also need an optical or USB output that connects to your capture card. Phantom power (48V) is required if you use a condenser microphone.
What is the best audio interface for streaming on a Windows PC?
For Windows, the MOTU M2 delivers the most reliable performance thanks to its industry-praised low-latency Windows drivers. The Behringer U-Phoria UMC404HD is a great budget pick, and the TC Helicon GoXLR Mini is the best choice for Windows-only workflows that need onboard processing.
Final Verdict
After testing all 10 audio interfaces for streaming across Twitch, YouTube Live, and podcast workflows, the Focusrite Scarlett Solo 3rd Gen is the best audio interface for streaming for most creators. It pairs cleanly with OBS Studio, drives an SM7B without drama, and ships with a 3-year warranty. Solo streamers who want one box that just works will not be disappointed.
Streamers who want premium audio quality should step up to the MOTU M2 for its ESS Sabre32 DAC and ultra-low-latency drivers. Budget creators should start with the M-Audio M-Track Solo for genuine plug-and-play simplicity. Multi-host podcasters get the most value from the Behringer UMC404HD with its four MIDAS preamps. Pick the one that matches your mic count, platform, and ecosystem, then go live with confidence.
