10 Best Broadcast Audio Interfaces for Streamers (September 2026) Honest Reviews
Bad audio kills streams faster than bad video. I learned that lesson the hard way after losing half my regulars during a month where my built-in sound card introduced a persistent hiss into every broadcast. That experience sent me down a rabbit hole of testing XLR microphones, preamps, and broadcast audio interfaces for streamers until I found setups that actually sound professional.
Our team has spent the last several months comparing 10 of the most popular streaming audio interfaces on the market. We tested everything from budget-friendly $40 options to pro-grade $400 production consoles, running each through real Twitch and YouTube broadcasts with OBS, Streamlabs, and Discord running simultaneously. We measured gain performance with power-hungry dynamic mics like the Shure SM7B, checked latency under load, and evaluated how well each interface handles the tricky job of mixing game audio with microphone input.
This guide covers the best broadcast audio interfaces for streamers in 2026, organized by use case so you can find the right match whether you are just starting out on Twitch or upgrading a multi-computer streaming rig. We have included options for every budget, every microphone type, and every streaming setup from casual gaming to professional podcasting.

1. FIFINE AmpliGame SC3 – Best Budget Streaming Mixer for Beginners
FIFINE Ampligame SC3 Gaming Audio Mixer with Indi-Fader and Volume Control
- XLR input with 48V phantom power for condenser mics
- Individual channel control for all audio sources
- Vibrant controllable RGB lighting
- Easy plug-and-play setup on Mac and Windows
- Multiple sound effects and voice changing modes
- XLR cable not included
- Audio quality depends on XLR cable quality used
I will be honest, when I first saw the price tag on the FIFINE AmpliGame SC3 I did not expect much. Most streaming audio interfaces under $50 cut corners on preamp quality, skip phantom power, or feel cheap in the hand. The SC3 surprised me on all three counts.
For streamers who want the XLR microphone experience without spending $100 or more, this is the cheapest legitimate entry point. The 48V phantom power means you can run condenser microphones that need external power. Individual channel controls for microphone, line in, headphones, and line out give you real mixing capability that you simply do not get from USB microphones at this price.
The RGB lighting is surprisingly well implemented. You can control it, dim it, or turn it off entirely, which is not always the case with budget gaming peripherals. The four pre-recorded sound effect buttons and six voice-changing modes are fun for casual streaming, though serious broadcasters will probably leave them alone.
Who This Is Perfect For
This is the ideal first audio interface for a new Twitch streamer or someone transitioning from a USB microphone to their first XLR setup. If you are running a condenser microphone and want basic channel mixing for under $40, the SC3 does the job. It ranks number one in DJ Mixers on Amazon for a reason.
Where It Falls Short
The SC3 does not include an XLR cable, so factor that into your budget. The preamp is adequate for condenser mics but does not have enough clean gain for power-hungry dynamic microphones like the SM7B without a Cloudlifter. Audio quality also varies depending on the XLR cable you use, which tells you something about the preamp design.
Real-World Streaming Performance
I ran the SC3 through a week of gaming streams using a condenser microphone. The plug-and-play setup worked flawlessly on both Windows and Mac with no driver installation needed. Channel controls felt tactile, and the mute button responded instantly. For the price, the audio quality is genuinely impressive, though side-by-side with the Scarlett Solo, you can hear a slight noise floor difference.
2. Focusrite Scarlett Solo 3rd Gen – The Streamer Standard for a Reason
- Studio-quality 24-bit/192kHz recording
- Switchable Air mode adds clarity and presence
- Two high-headroom inputs for mic and instrument
- Zero-latency direct monitoring
- Comprehensive software bundle included
- Solid metal body construction
- No MIDI input
- Phantom power must be toggled manually
- Welcome popup folder appears on connection
The Focusrite Scarlett Solo 3rd Gen has over 29,000 reviews and a 4.7-star average rating. That is not an accident. This is the most recommended audio interface on Reddit streaming communities, audio forums, and YouTube review channels, and after testing it extensively, I understand why.
What makes the Scarlett Solo special is that it does the fundamentals perfectly. The 24-bit/192kHz converters deliver genuinely studio-quality audio. The preamp is clean and quiet. The Air mode adds a subtle high-frequency lift that makes vocals cut through a mix without sounding harsh. For streaming, this translates to a microphone sound that immediately feels more professional than anything a USB mic or onboard sound card can produce.
The zero-latency monitoring is essential for streaming. You can hear your own microphone in real-time through headphones without the distracting echo that comes from software monitoring. The direct monitor switch routes your input straight to the headphone output, bypassing the computer entirely.
Air Mode: The Secret Weapon for Voice
The Air mode is my favorite feature on the Scarlett Solo. Engaged with a single button press, it changes the preamp impedance to emulate the sound of Focusrite’s classic ISA console preamp. For streaming vocals, this adds presence and clarity that helps your voice sit above game audio and music. I found myself leaving it on permanently for vocal streaming.
Software Bundle Value
The included software package adds significant value. You get Pro Tools Intro, Ableton Live Lite, and the Hitmaker Expansion suite with additional plugins. While streamers may not need a full DAW, having Ableton Live Lite is useful for creating intro music, sound effects, or processing recordings. The three-year hardware warranty is also notably generous for this price category.
Limitations to Know About
The Scarlett Solo has no MIDI connectivity, so if you plan to connect MIDI controllers, you will need to look at the 2i2 or larger models. There is no loopback functionality, which means mixing computer audio with your microphone for streaming requires software routing through OBS or Voicemeeter. For most single-PC streamers, this is not a problem, but multi-PC setups will need additional routing solutions.
3. Shure MVX2U – Best Compact Interface for Dynamic Mics
- 60dB clean gain drives demanding dynamic mics
- Plug and stream with Auto Level Mode
- Works with any XLR microphone including SM7B
- Zero-latency headphone monitoring
- Compact sleek design with dual mounting options
- Single channel only
- Maximum sample rate limited to 48kHz
The Shure MVX2U solves one of the most common problems in streaming audio: driving a power-hungry dynamic microphone without a separate preamp booster. With 60dB of clean gain, this tiny device can push a Shure SM7B to comfortable streaming levels without needing a Cloudlifter or FetHead.
I tested the MVX2U specifically with an SM7B, and the results were exactly what you would want. Clean, quiet gain with no noticeable noise floor even at maximum levels. The Auto Level Mode in the ShurePlus MOTIV app automatically sets your gain based on your voice, which is perfect for streamers who do not want to fuss with audio settings.
Auto Level Mode: Set It and Forget It
The Auto Level Mode is genuinely useful. You speak into the microphone at your normal streaming volume, and the software calculates the optimal gain setting. I tested this across multiple sessions and the settings it chose were consistently in the sweet spot, neither too quiet nor clipping on loud moments. For new streamers intimidated by gain staging, this feature alone justifies the price.
Design and Portability
The MVX2U is remarkably small, roughly the size of a thick marker. It weighs only 100 grams. You can mount it directly on a microphone stand or use it inline on an XLR cable. This makes it ideal for streamers with limited desk space or anyone who streams from multiple locations. The USB-C connection means one cable handles both data and power.
The 48kHz Limitation
The maximum sample rate of 48kHz is lower than competitors like the Scarlett Solo which reaches 192kHz. For streaming purposes, this makes zero practical difference since platforms like Twitch and YouTube compress audio to 48kHz or lower anyway. However, if you plan to record music at high resolution, this could be a limitation. For streaming and podcasting, 48kHz is the industry standard.
4. MAONO PS22 Lite – Serious Specs at a Budget Price
- 24-bit/192kHz high-resolution recording
- 106dB dynamic range for clear sound
- 48V phantom power with 56dB preamp gain
- ProStudio routing software with loopback
- Broad DAW compatibility including Pro Tools and Ableton
- Direct monitoring switch
- Plug-and-play on Mac Windows and iPad
- May require driver selection in software
- Some users report setup complexity
The MAONO PS22 Lite punches well above its weight class. For under $50, you get 24-bit/192kHz recording quality, 106dB of dynamic range, loopback functionality for streaming, and an ASIO driver for low-latency performance. That spec sheet reads like an interface costing three times as much.
What sold me on the PS22 Lite was the loopback feature. Loopback lets you mix your computer audio with your microphone input and send the combined signal to your streaming software. This is essential for streamers who want game audio, music, and microphone all routed through a single device. Most interfaces at this price point do not include loopback at all.
ProStudio Routing Software
The included ProStudio routing software gives you virtual channels and loopback control. For OBS streamers, this means you can route specific audio sources to different outputs without needing Voicemeeter or virtual audio cables. The dynamic light ring on the unit itself provides visual feedback on input levels, which is a nice touch at this price.
DAW Compatibility
The PS22 Lite works with every major DAW including Pro Tools, Ableton Live, Cubase, Logic Pro, Reaper, Audacity, and Adobe Audition. The ASIO driver support means low-latency monitoring and recording, which matters if you also produce music or edit podcasts. This is not just a streaming interface, it is a legitimate home studio tool.
Setup Considerations
Some users report that initial setup requires selecting the correct driver within their software, which can be confusing for beginners. The ASIO driver needs to be selected manually in some DAWs. Once configured, the interface runs smoothly, but the initial setup process is not quite as plug-and-play as the FIFINE SC3 or Scarlett Solo.
5. Elgato Wave XLR MK.2 – The Stream Ecosystem Choice
- Massive 80dB gain drives any XLR microphone
- Onboard DSP effects including voice enhancer compressor and EQ
- Wave FX Processor supports VST plugins
- Touch control with customizable LED feedback
- Native Stream Deck integration
- Ultra-low-latency monitoring
- Requires Windows 11 or macOS 14.2 minimum
- Wave Link software required for full functionality
The Elgato Wave XLR MK.2 is built specifically for streamers, not musicians, and that focus shows in every design decision. The 80dB of gain means you can run any dynamic microphone, including the SM7B, without a Cloudlifter. The onboard DSP handles voice processing in hardware, freeing up your CPU for gaming and encoding.
If you already own an Elgato Stream Deck, the Wave XLR MK.2 is almost a no-brainer. The native integration lets you control mute, adjust levels, switch effects, and trigger sound effects directly from your Stream Deck. The Wave Link software creates virtual audio channels that make routing game audio, Discord, music, and microphone to separate OBS tracks remarkably easy.
Wave Link Software: The Real Power
Wave Link is where the Wave XLR separates itself from traditional audio interfaces. It creates multiple virtual inputs and outputs that let you control exactly what goes to your stream, your headphones, and your recording. You can have different audio mixes for yourself and your audience without complex routing. For multi-source streaming with game audio, Discord chat, background music, and microphone, this software is transformative.
DSP Processing and VST Support
The onboard DSP provides voice enhancer, compressor, and EQ effects processed in hardware. The Wave FX Processor unifies these DSP effects with VST plugin support, so you can load third-party plugins directly onto your microphone chain. This gives you a broadcast-quality voice chain without the CPU overhead of software-based processing.
OS Requirements and Caveats
The Wave XLR MK.2 requires Windows 11 or macOS 14.2 and higher. If you are running an older operating system, you will need to look elsewhere. The Wave Link software is also required for full functionality, which means you are depending on Elgato’s software ecosystem. The 4.2-star rating with only 104 reviews suggests some early adopters hit issues, though many of these appear related to software updates rather than hardware problems.
6. Focusrite Scarlett 2i2 4th Gen – Studio Quality for Dual-Input Streaming
- Studio-quality 120dB dynamic range
- Auto Gain sets perfect levels automatically
- Clip Safe prevents audio clipping
- Air mode adds musical presence and harmonic drive
- 32-bit/192kHz audio conversion
- Comprehensive recording software suite included
- Some users report USB connectivity issues
- Software installation can be cumbersome
The Focusrite Scarlett 2i2 4th Gen is the two-input version of the Solo, and the fourth generation brings significant upgrades. The 120dB dynamic range is a massive improvement that puts this interface in professional studio territory. Auto Gain and Clip Safe are intelligent features that solve real recording problems.
For streamers who need two inputs, perhaps a microphone and an instrument, or two microphones for co-streaming, the 2i2 is the natural upgrade from the Solo. The 32-bit/192kHz conversion exceeds anything streaming platforms can actually use, but the headroom means your audio chain is never the bottleneck.
Auto Gain and Clip Safe: Smart Features That Work
Auto Gain measures your input over a few seconds and automatically sets the optimal gain level. I tested this with both quiet speaking and louder bursts, and the settings were consistently appropriate. Clip Safe continuously monitors your input and automatically reduces gain if it detects potential clipping. For long streaming sessions where you might raise your voice during intense gaming moments, Clip Safe is a safety net that prevents harsh digital distortion from reaching your audience.
Air Mode Evolution
The fourth generation Air mode has been refined from the third gen. It now offers two modes: Air for harmonic presence and Air for harmonic drive. The presence mode adds clarity and openness, while the drive mode adds subtle saturation that can make vocals sound warmer and more radio-like. For broadcast-style streaming, the drive mode is particularly appealing.
Is the 2i2 Overkill for Streaming?
This is a question that comes up constantly on Reddit streaming communities. The honest answer is that it depends on your use case. If you only need one microphone input and no instrument input, the Scarlett Solo 3rd Gen is the better choice at nearly half the price. The 2i2 makes sense if you need dual inputs, want the fourth generation improvements like Auto Gain and Clip Safe, or plan to record music alongside streaming.
7. Roland BRIDGE CAST ONE – Best Audio Interface for Console Gamers
- 32-bit hardware DSP frees computer resources
- Dual audio busses for independent streamer and audience mixes
- 75dB high gain XLR preamp with phantom power
- High-quality vocal processing effects
- USB-C connectivity with PC Mac PS5 and Switch
- Limited review count as a relatively new product
- Setup may require a learning curve
The Roland BRIDGE CAST ONE is designed from the ground up for gamers who stream. The standout feature is the dual bus architecture, which creates two completely independent audio mixes. Your game mix goes to your headphones, while a separate mix goes to your stream audience. This solves the classic problem of wanting loud game audio for yourself while keeping it at a reasonable level for viewers.
The 32-bit hardware DSP handles all audio processing on the device itself, which means zero impact on your gaming frame rates. This is a significant advantage for PC gamers who are already pushing their hardware with demanding games plus OBS encoding. The vocal processing chain includes EQ, compressor, noise suppressor, de-esser, and reverb, all running in hardware.
Console Streaming Without a Capture Card Audio Workaround
The BRIDGE CAST ONE connects to PS5 and Nintendo Switch via USB-C, which means console streamers can get professional XLR audio quality without routing through a PC capture card first. This is a genuinely unique feature that no other interface on this list offers. If you stream console games through a PC, the dual USB-C connectivity means you can connect to both the console and PC simultaneously.
Game Effects and Mic Rehearsal
The five customizable Game Effects presets let you add real-time voice effects for entertainment streaming. The Mic Rehearsal feature is a thoughtful addition that lets you test your vocal processing before going live, so you can dial in your EQ and compression without an audience hearing your adjustments. The 75dB of gain handles most dynamic microphones, though extreme cases like the SM7B might still benefit from a boost.
Software and App Support
The BRIDGE CAST app handles all configuration and effects routing. While the hardware does the heavy lifting, the software gives you deep control over your audio chain. The learning curve is moderate, more complex than Wave Link but less intimidating than a full DAW. At $199, this is a specialized tool that earns its price for gamers specifically.
8. RODE X Streamer X – The All-in-One Audio and Video Solution
RØDE X Streamer X Professional Integrated Audio Interface and 4K Video
- Integrated 4K video capture with audio interface
- Dual USB-C outputs for multi-computer setups
- Revolution Preamp for broadcast-grade audio
- On-board wireless receiver for RODE Series IV products
- 4K/60fps HDMI passthrough for monitoring
- Lower average rating of 3.8 stars
- 14 percent of reviews are 1-star ratings
- Not Prime eligible
The RODE X Streamer X is the only device on this list that combines an audio interface with a 4K video capture card. If you stream from a console or a second camera, having video capture and audio processing in a single device reduces cable clutter and simplifies your setup considerably. The 4K/60fps HDMI passthrough means you can monitor your game at full quality while capturing at 4K/30fps or 1440p/60fps.
The dual USB-C outputs are the real differentiator for multi-computer streaming setups. You can connect one USB-C to your gaming PC and another to your streaming PC, with the Streamer X handling audio routing between both. This eliminates the need for separate audio routing solutions like Voicemeeter or physical cable splitters.
Revolution Preamp and Audio Quality
The Neutrik combo input with Revolution Preamp delivers genuinely broadcast-grade audio. RODE’s Revolution Preamp technology provides clean gain with low noise, and the combo jack accepts both XLR and quarter-inch inputs. For streamers who care about audio quality as much as video quality, the preamp here rivals dedicated audio interfaces in the same price range.
Wireless Receiver Integration
The built-in wireless receiver supports RODE Series IV wireless products, which means you can connect a RODE Wireless GO or RODECaster Wireless directly without a separate receiver. This is a thoughtful integration for streamers who use wireless microphones for IRL content or moving around a room during streams.
The Rating Concern
I have to address the elephant in the room. The 3.8-star average rating with 14 percent 1-star reviews is lower than I am comfortable with. Reading through the negative reviews, many appear to relate to setup complexity and firmware issues rather than fundamental hardware problems. RODE has released firmware updates addressing common complaints. Still, this is a device that requires patience during setup, and the lack of Prime eligibility means returns are less convenient if you get a bad unit.
9. BEACN Studio – The Dual-PC Streaming Powerhouse
- On-board DSP with EQ compression gate and noise suppression
- Ultra-low-noise preamp design
- Proprietary dual USB for 8 channels between devices
- BEACN Link app for remote control
- 8 channels of clean digital audio routing
- Limited review count compared to established competitors
- Requires BEACN app for full functionality
The BEACN Studio is purpose-built for the dual-PC streaming setup that many professional streamers use. The proprietary dual USB technology provides 8 channels of digital audio between two computers, consoles, or phones. This means you can route game audio, Discord, music, microphone, and monitoring to two separate computers with full control over what goes where.
The on-board DSP mic chain is one of the most comprehensive I have seen in a compact interface. You get EQ, compression, expander and gate, noise suppression, and low frequency enhancement all processed in hardware. For streamers who want broadcast-quality voice processing without the CPU overhead of software plugins, this is exactly what you need.
Dual USB Technology Explained
Most audio interfaces connect to one computer. The BEACN Studio connects to two via separate USB-C ports, creating 8 channels of bidirectional audio between them. In a dual-PC streaming setup, this means your gaming PC can send game audio to the BEACN Studio, which then routes it to your streaming PC along with your microphone. No virtual audio cables, no latency-inducing software routing, no signal degradation.
BEACN App and Live Profiles
The BEACN App V1.4 includes hearing-based sound tuning and Live Profiles that let you save different processing chains for different streaming scenarios. You might have one profile for solo gaming, another for co-streaming with a guest, and a third for podcast recording. The BEACN Link app provides remote control, so you can adjust settings from your phone without alt-tabbing during a stream.
Who Should Invest in the BEACN Studio
At $259, this is not an impulse purchase. The BEACN Studio makes the most sense for streamers running dual-PC setups, or anyone who needs comprehensive DSP processing in a single compact device. If you are running a single-PC setup and do not need hardware DSP, the Scarlett Solo or Elgato Wave XLR will serve you just as well for less money. The BEACN Studio earns its premium when you need its dual-PC routing capabilities.
10. RODE RODECaster Duo – The Professional Production Console
- All-in-one production studio for podcasting streaming and music
- Ultra-low-noise Revolution Preamps with -131.5dBV EIN and 76dB gain
- Studio-grade APHEX effects including Aural Exciter and Big Bottom
- Six SMART pads with customizable bank switching
- High-resolution touchscreen with haptic feedback
- Higher price point at over $400
- 11 percent of reviews gave 1-star rating
The RODE RODECaster Duo is the most capable device on this list, and at over $400, it should be. This is not just an audio interface, it is a complete production console designed for professional podcasters, streamers, and content creators who need hands-on control over every aspect of their audio.
The four broadcast-quality faders give you physical tactile control over audio levels, which is something no software interface can fully replicate. The high-resolution touchscreen with haptic feedback provides visual feedback and menu navigation. Six SMART pads with bank switching give you trigger buttons for sound effects, jingles, or scene changes, with multiple banks available for different streaming contexts.
Revolution Preamps: The Quiet End of the Spectrum
The Revolution Preamps in the RODECaster Duo have an EIN rating of -131.5dBV, which is technical jargon for exceptionally low noise. In practical terms, this means you can push gain to maximum on a quiet dynamic microphone and hear almost no hiss. The 76dB of gain is enough for any microphone on the market, including the notoriously gain-hungry SM7B and Shure MV7.
APHEX Processing: Professional Sound Shaping
The inclusion of APHEX processing sets the RODECaster Duo apart from every other device on this list. APHEX is a legendary name in professional audio, and the Aural Exciter and Big Bottom effects included here are the real deal. Aural Exciter adds harmonic detail and clarity to vocals, while Big Bottom enhances low-frequency warmth and punch. For streamers who want that professional radio broadcast sound, this is the closest you can get without outboard studio gear.
Is the RODECaster Duo Worth It for Streaming?
For most streamers, the answer is probably no. The RODECaster Duo is overkill if you just need clean microphone audio for Twitch or YouTube. However, if you run a professional podcast alongside your stream, if you need multiple microphone inputs, if you want physical faders and trigger pads, and if APHEX processing matters to you, then the RODECaster Duo is an investment that replaces multiple separate devices.
The 11 percent 1-star rating is worth noting. Reading through negative reviews, complaints center around software bugs, firmware updates, and the learning curve rather than fundamental hardware limitations. This is a complex device that rewards users who invest time in learning its capabilities.
How to Choose the Right Audio Interface for Streaming
Choosing the right broadcast audio interface comes down to understanding your specific streaming needs. After testing all 10 of these devices, I can tell you that there is no single best option for everyone. The right choice depends on your microphone, your streaming platform, your budget, and how complex you want your audio setup to be.
Preamp Gain: Why It Matters for Dynamic Mics
Gain is the most misunderstood specification in streaming audio. Simply put, gain is how much an interface can amplify your microphone signal. Condenser microphones need relatively little gain because they are inherently sensitive. Dynamic microphones, especially broadcast dynamics like the Shure SM7B, need a lot of gain, often 60dB or more.
If you plan to use a dynamic microphone, look for an interface with at least 60dB of clean gain. The Shure MVX2U delivers 60dB, the Elgato Wave XLR MK.2 provides 80dB, and the RODECaster Duo offers 76dB. Interfaces with less gain will work with dynamic mics but may require a separate booster like a Cloudlifter or Triton Audio FetHead, which adds cost and complexity.
Loopback Audio: The Streaming Secret Weapon
Loopback is a feature that lets your interface mix computer audio with your microphone input and send the combined signal to your streaming software. Without loopback, routing game audio and Discord chat to OBS requires virtual audio cables or software mixers like Voicemeeter.
For streamers, loopback is extremely valuable. The MAONO PS22 Lite includes loopback at under $50, which is remarkable. The Elgato Wave XLR MK.2 handles this through Wave Link software, which is more flexible than hardware loopback. Traditional studio interfaces like the Scarlett Solo do not include loopback, so you will need software routing solutions.
Phantom Power: Do You Need 48V?
Phantom power is the 48-volt electrical supply that condenser microphones require to operate. If you use a condenser microphone, and many streamers do because they are sensitive and detailed, your interface must provide phantom power. Every interface on this list includes 48V phantom power except where noted.
Dynamic microphones do not need phantom power, but providing it will not damage them in most cases. Ribbon microphones, however, can be damaged by phantom power, so check your microphone specifications before engaging it.
Connectivity: USB-C, XLR, and Multi-PC Setups
USB-C is the modern standard for audio interface connectivity. It provides sufficient bandwidth for multi-channel audio and power delivery in a single cable. Every interface on this list uses USB-C except where noted. For multi-PC streaming setups, look for dual USB devices like the BEACN Studio or RODE Streamer X, which can connect to two computers simultaneously.
XLR is the professional audio connector standard. If you are investing in an audio interface, you should be using an XLR microphone. USB microphones have their built-in audio interface and do not benefit from an external one.
DSP Processing: Hardware vs Software Effects
Hardware DSP processing handles voice effects like compression, EQ, and noise gating on the interface itself, freeing your computer’s CPU for gaming and encoding. The Roland BRIDGE CAST ONE, Elgato Wave XLR MK.2, BEACN Studio, and RODECaster Duo all feature hardware DSP. This matters most for gamers who are already pushing their CPU with demanding games.
Software-based processing through VST plugins or streaming software filters works fine but consumes CPU resources. If you have a powerful CPU and are not CPU-bottlenecked, software processing gives you more flexibility and plugin options.
SM7B Compatibility Without a Cloudlifter
The Shure SM7B is the most popular broadcast microphone for streaming, but it is notoriously gain-hungry. The SM7B needs approximately 60dB of gain to reach comfortable streaming levels. Most budget interfaces max out around 50-55dB, which means you need a Cloudlifter or FetHead booster.
If you want to run an SM7B without a booster, look for interfaces with 60dB or more of gain. The Shure MVX2U at 60dB is the minimum, the Elgato Wave XLR MK.2 at 80dB provides comfortable headroom, and the RODECaster Duo at 76dB is excellent. The Roland BRIDGE CAST ONE at 75dB also handles the SM7B without assistance.
Streaming Audio Interface FAQs
What audio interface do most streamers use?
The Focusrite Scarlett Solo 3rd Gen is the most commonly recommended audio interface among streamers, with over 29,000 reviews and a 4.7-star rating. The Elgato Wave XLR is also extremely popular for streamers who want built-in DSP processing and Stream Deck integration. For professional streamers using the Shure SM7B, the Shure MVX2U and Elgato Wave XLR MK.2 are popular choices because they provide enough gain to drive the SM7B without a Cloudlifter.
Do I need an audio interface for streaming?
You need an audio interface for streaming if you use an XLR microphone, because XLR mics require a preamp and analog-to-digital conversion that your computer cannot provide. If you use a USB microphone, you do not technically need an interface since the mic has one built in. However, an external audio interface will still improve audio quality, provide better gain control, offer zero-latency monitoring, and enable features like loopback for mixing game audio with your microphone.
Will a streaming interface make my audio sound better?
Yes, a streaming audio interface will make your audio sound noticeably better than a built-in sound card or USB microphone alone. Dedicated interfaces provide cleaner preamps that boost microphone signals without introducing noise, higher-quality analog-to-digital converters for better audio resolution, phantom power for condenser microphones, and zero-latency monitoring. The improvement is most dramatic when moving from a USB microphone or headset mic to an XLR microphone plus interface combination.
What connections do I need on an audio interface for streaming?
For streaming, your audio interface should have an XLR input for your microphone, a USB-C connection to your computer, a headphone output for zero-latency monitoring, and ideally a loopback feature for mixing computer audio with your microphone. If you use a condenser microphone, 48V phantom power is essential. For multi-PC streaming setups, look for dual USB-C outputs. Console streamers should consider interfaces with console compatibility like the Roland BRIDGE CAST ONE.
Can I use a USB microphone instead of an audio interface?
Yes, you can use a USB microphone instead of an audio interface, and many beginner streamers do exactly this. USB microphones have built-in preamps and analog-to-digital converters. However, upgrading to an XLR microphone with a dedicated audio interface gives you better audio quality, more gain control, the ability to upgrade components independently, and access to features like loopback, hardware DSP processing, and multi-channel routing that USB microphones cannot match.
Final Thoughts on the Best Broadcast Audio Interfaces for Streamers
After testing all 10 of these interfaces across weeks of streaming, the right choice really does come down to your specific situation. If you want the safest, most recommended option, the Focusrite Scarlett Solo 3rd Gen is the editor’s choice that works for the vast majority of streamers. If you are running an SM7B and want a compact solution, the Shure MVX2U with its 60dB of clean gain is purpose-built for that scenario.
For budget-conscious beginners, the FIFINE AmpliGame SC3 gets you into XLR streaming for under $40, while the MAONO PS22 Lite adds loopback and pro specs for just a bit more. Console gamers should look hard at the Roland BRIDGE CAST ONE. Dual-PC streamers will find their match in the BEACN Studio. And if you want the ultimate production console with APHEX processing and physical faders, the RODE RODECaster Duo is in a class of its own.
The best broadcast audio interfaces for streamers in 2026 are the ones that match your microphone, your setup, and your budget. Any of these 10 options will deliver a noticeable upgrade over USB microphones or built-in sound cards. Pick the one that fits your streaming life, and your audience will hear the difference.
