Audio interfaces with loopback let you route computer audio into a stream, podcast, or recording alongside microphones and instruments. I’d put the MOTU M4 first for its versatile I/O and practical metering, while the Zoom AMS-24 stands out for stream-focused controls and the Scarlett 2i2 4th Gen for a familiar two-input recording setup. The main tradeoff is between flexible routing and a simpler, more portable device, with input count and compatibility also shaping the choice. Some models are better suited to stereo mobile streaming than to multi-microphone recording. Read on for the full breakdown of what separates these 12 options and which type of setup each one suits.

Key Takeaways
- The MOTU M4 is the strongest all-rounder in this group: its 4×4 I/O and clear metering suit buyers who need more routing room than a basic two-input interface provides.
- The Zoom AMS-24 is the more stream-oriented alternative: its format and controls suit live content workflows, while the M4 gives greater appeal to buyers balancing streaming with broader recording needs.
- Compact and mobile options serve a different job: the iRig Stream prioritizes stereo capture and device flexibility rather than multiple mic and instrument inputs.
- Several models share a 2×2 format, but that does not make them interchangeable: controls, software routing, and intended use matter as much as the headline channel count.
- Podcast bundles and high-gain designs target specific setups: the MAONO E2 Gen2 and P1 may suit voice-focused creators, but buyers should match their included controls and connection needs to their actual workflow.

More Details on Our Top Picks
MAONO P2 Hybrid USB Audio Interface with Dual XLR Inputs
The MAONO P2 is the clearest fit here for creators who want to bring a computer and a phone or tablet into one streaming setup. Its dual XLR inputs and loopback make it more flexible for two-mic sessions than the Zoom AMS-22, which has just one XLR/TRS combo input. The P2 also supports 24-bit/192 kHz recording, giving it a higher stated recording ceiling than either Zoom AMS model. Independent mute controls and direct monitoring help manage a live session without relying entirely on software. The tradeoff is that some routing and effects rely on the included software, and the supplied details do not state a warranty term. Choose it for hybrid streaming flexibility; skip it if you want a simpler, clearly documented setup.
Pros:- Can connect a computer and a phone or tablet simultaneously
- Two XLR inputs suit interviews and two-microphone streams
- Loopback, direct monitoring, and independent mute controls support live production
- Supports recording up to 24-bit/192 kHz
Cons:- Some routing and effects features depend on the included software
- Warranty duration is not specified in the supplied product information
Best for: Streamers who need two XLR microphones and want to connect a computer alongside a phone or tablet.
Not ideal for: Buyers who want fully specified warranty coverage or prefer loopback and routing that do not depend on bundled software.
- Connectivity:USB-C
- Inputs:Dual XLR

Our verdict“Choose the MAONO P2 if your streaming setup needs two XLR microphones and simultaneous computer-and-mobile connections.”
Zoom AMS-22 USB Audio Interface for Recording and Streaming
The Zoom AMS-22 prioritizes portability and straightforward mode switching over input count. Its Music and Streaming modes adapt the routing for DAW recording or a livestream, while dedicated loopback and direct monitoring controls make the streaming use case explicit. At 230 g and USB bus-powered, it is easier to carry than the larger MAONO P2, but the tradeoff is a single XLR/TRS combo input. That makes it a better match for a solo host than a two-person microphone show. The stereo 3.5 mm input adds a way to bring in another source, though it is not a second XLR input. Its 48 kHz ceiling is also lower than the 192 kHz support listed for the Focusrite Scarlett 2i2 4th Gen.
Pros:- Dedicated loopback and direct monitoring controls
- Music and Streaming modes adapt routing to different workflows
- USB bus-powered design weighs 230 g
- Works with PC, Mac, iOS, and Android
Cons:- Only one XLR/TRS combo input for microphones or instruments
- Maximum sample rate is 48 kHz
Best for: Mobile solo streamers and musicians who need one microphone input, loopback, and a compact bus-powered interface.
Not ideal for: Interview hosts who need two XLR microphones or producers seeking recording rates above 48 kHz.
- Inputs:1 XLR/TRS combo input with Hi-Z; 1 stereo 3.5 mm input
- Outputs:2
- Channels:2
- Maximum sample rate:48 kHz
- Power:USB bus-powered
- Compatible platforms:PC, Mac, iOS, Android
- Weight:230 g
- Warranty:1 year replacement
Our verdict“Pick the Zoom AMS-22 for a portable, single-mic streaming rig rather than a multi-microphone studio setup.”
Focusrite Scarlett 2i2 4th Gen USB-C Audio Interface
The Scarlett 2i2 4th Gen is the recording-focused choice in this group, pairing two low-noise preamps with a stated 120 dB dynamic range and helpful level-management tools. Auto Gain and Clip Safe can reduce setup friction for creators who are learning to set microphone levels, while Air mode offers a tonal option for vocals and guitars. Loopback is not explicitly listed in the supplied product details, so I would not rank it ahead of the MAONO P2 or Zoom AMS-24 for buyers whose main requirement is a clearly documented streaming loopback workflow. Compared with the Zoom AMS-24, the Scarlett offers a higher stated sample rate and dynamic range, but the Zoom spells out its streaming mode and independent headphone mixes. The Scarlett is stronger as a compact recording hub than as a loopback-first pick.
Pros:- Two low-noise microphone preamps and converters with a stated 120 dB dynamic range
- Auto Gain and Clip Safe help manage input levels
- Air mode provides an alternate sound character for vocals and guitars
- Includes recording software and a plugin bundle
Cons:- Loopback is not specified in the supplied product details
- Limited to two audio inputs and two channels
- Bundled USB cable or power adapter is not specified
Best for: Home-recording musicians and vocalists who want two quality preamps, assisted gain setting, and bundled recording software.
Not ideal for: Buyers choosing primarily for confirmed loopback controls or anyone needing more than two inputs.
- Connectivity:USB
- Channels:2
- Microphone preamps:2
- Audio inputs:2
- Maximum sample rate:192 kHz
- Dynamic range:120 dB
- Supported operating systems:Mac OS, Windows OS, iOS
- Warranty:3 years
Our verdict“Choose the Scarlett 2i2 for recording-focused sound and level-assistance features, but verify loopback support before buying it for streaming.”
Zoom AMS-24 USB Audio Interface
The Zoom AMS-24 earns its place through workflow flexibility rather than high-resolution recording specs. In Music mode, it can send tracks individually to a DAW and provide independent headphone mixes; Streaming mode combines inputs into one feed. That makes it a more adaptable production tool than the single-input AMS-22, especially for creators who alternate between recording and broadcasting. Its loopback and direct monitoring controls also make the streaming function clear. The main limitation is the 48 kHz maximum sample rate, well below the 192 kHz listed for the MAONO P2 and Scarlett 2i2. Two inputs are enough for a modest home setup, but not for a larger ensemble. Choose it when mode switching and monitoring options matter more than a higher recording ceiling.
Pros:- Music and Streaming modes support distinct recording and broadcast workflows
- Music mode offers independent headphone mixes
- Loopback and direct monitoring controls support livestreaming
- Bus-powered and compatible with PC, Mac, iOS, and Android
Cons:- Maximum sample rate is 48 kHz
- Limited to two input channels
Best for: Creators who record separate tracks in a DAW and also stream, with a need for independent headphone mixes.
Not ideal for: Producers who need more than two input channels or want sample rates above 48 kHz.
- Inputs:2 XLR/TRS
- Outputs:2 headphone outputs and 2 main TRS outputs
- Channels:2
- Maximum sample rate:48 kHz
- Power:Bus-powered
- Compatible devices:PC, Mac, iOS, Android

- Warranty:1 year replacement
Our verdict“Pick the AMS-24 if you switch between DAW recording and livestreaming and value routing flexibility over high sample rates.”
PIYONE Q2 2×2 USB-C Audio Interface, 24-bit/192 kHz, Alloy Grey
The PIYONE Q2 offers the core hardware for a two-input recording setup: combo inputs, 48V phantom power, Hi-Z support, and zero-latency direct monitoring. Its 24-bit/192 kHz specification matches the MAONO P2 and Scarlett 2i2 on stated maximum sample rate, but the product details do not list loopback. That distinction matters: the Zoom AMS-24 and MAONO P2 are more clearly suited to streamers who need computer audio routed into a broadcast mix. The Q2 is instead a straightforward pick for Windows users recording microphones or instruments, with bus power and a 3.5 mm headphone connection. Its stated operating-system compatibility is Windows only, which makes it a less flexible mobile choice than either Zoom model. The supplied details also do not identify routing software or streaming controls.
Pros:- Two XLR/TRS combo inputs support microphones and other sources
- 48V phantom power and Hi-Z input support a range of recording gear
- Supports 24-bit/192 kHz recording
- Zero-latency direct monitoring and bus-powered operation
Cons:- Supplied operating-system compatibility lists Windows only
- Loopback is not specified in the supplied product details
- Streaming modes or routing software are not specified
Best for: Windows-based home recordists who need two mic or instrument inputs, phantom power, and direct monitoring.
Not ideal for: Mac or mobile users, and streamers who require explicitly specified loopback routing.
- Model:Q2
- Channels:2
- Connectivity:USB-C
- Inputs:2 XLR/TRS combo inputs
- Maximum sample rate:192 kHz
- Bit depth:24-bit
- Phantom power:48V
- Operating system:Windows
- Warranty:2-year limited
Our verdict“Choose the PIYONE Q2 for a basic Windows two-input recording setup, not as a confirmed loopback solution.”
MOTU M4 4×4 USB-C Audio Interface
I’d choose the MOTU M4 when loopback is part of a broader computer-based recording setup, not the only job the interface needs to do. Its 4-in/4-out layout, two mic preamps, and MIDI I/O give it more room for instruments and connected gear than the two-channel Focusrite Scarlett Solo 4th Gen. It also supports recording up to 192 kHz and offers low-latency monitoring, making it a flexible hub for recording and streaming workflows. The tradeoff is that the supplied product details don’t specify the loopback routing method or controls, so buyers should verify those details against their intended software and setup. Its listed operating system versions are dated, too, and the larger feature set may be unnecessary for a solo streamer.
Pros:- Four inputs and four outputs provide more room for connected instruments and playback routing.
- Two microphone preamps support recording two mic sources.
- MIDI I/O adds a direct connection for compatible keyboards and controllers.
- Low-latency monitoring and sample rates up to 192 kHz suit recording as well as streaming.
Cons:- The supplied product details do not explain how loopback is configured or controlled.
- Listed operating system versions are dated, so current compatibility should be checked.
- Its extra connections may be unnecessary for a creator who only needs one microphone and playback capture.
Best for: Home-studio musicians and streamers who need MIDI, two microphone preamps, and more input/output capacity than a basic two-channel interface.
Not ideal for: Solo creators seeking a tiny, simple loopback device, or buyers who need clearly documented current operating-system support and loopback controls.
- Inputs/outputs:4-in/4-out
- Microphone preamps:2
- Connectivity:USB-C
- MIDI I/O:Yes
- Monitoring:Low-latency
- Maximum sample rate:192 kHz
- Supported devices:Laptop, personal computer, smartphone
- Dimensions:4.25 x 8.25 x 1.75 in
Our verdict“Choose the MOTU M4 if you want loopback within a more expandable recording and MIDI setup, rather than a minimal streaming interface.”
iRig Stream Stereo Audio Interface – USB‑C, Lightning & USB – 24‑bit/48 kHz Recording for iPhone, iPad, Mac, PC, Android
The iRig Stream is the lineup’s clearest fit for capturing a stereo source from a phone-friendly setup. Its RCA inputs and loopback for playback suit live jamming or streaming music alongside a device’s audio, while USB-C, Lightning, and standard USB connections offer more connection options than the USB-C-only PIYONE Q2. Direct monitoring helps you hear the incoming signal without monitoring delay. That portability comes with firm limits: this is a stereo-only interface, not a multitrack recorder with separate mic and instrument channels. Its gain indication is also basic, and some phones or computers may need adapters. I’d pick it for a compact stereo feed, not for a growing microphone-and-instrument studio.
Pros:- RCA stereo inputs suit playback sources and stereo jamming setups.
- Loopback supports capturing device playback alongside an incoming audio source.
- USB-C, Lightning, and USB connections cover a broad range of phones, tablets, and computers.
- Zero-latency direct monitoring and a 2.4-ounce body favor portable use.
Cons:- Two stereo channels do not provide multitrack recording or separate microphone inputs.
- Gain control is limited to a simple LED indicator.
- Some device connections may require additional adapters.
Best for: Mobile streamers and musicians who want to send stereo RCA playback into an iPhone, iPad, Android device, or computer with loopback for jamming.
Not ideal for: Podcasters recording multiple separate microphones or musicians who need multitrack inputs, hands-on gain adjustment, or detailed routing.
- Channels:2, stereo RCA inputs
- Sample rate:24-bit / 96 kHz
- Connectivity:USB-C, Lightning, USB, RCA
- Compatibility:iPhone, iPad, Android, Mac/PC
- Operating systems:iOS, Android, Windows, macOS
- Monitoring:Zero-latency direct monitoring
- Dimensions:4.1 x 1.15 x 1.25 in
- Weight:2.4 ounces
Our verdict“Pick the iRig Stream for portable stereo streaming and playback loopback, but choose a multichannel interface if you need separate mic or instrument tracks.”
Focusrite Scarlett Solo 4th Gen USB-C Audio Interface
The Scarlett Solo 4th Gen makes sense for a creator whose loopback workflow starts with one microphone or one instrument. It pairs a dedicated XLR mic preamp with a Hi-Z instrument input, so a vocalist can record a mic while a guitarist has an instrument connection ready. Its 120 dB dynamic range and Air mode target clean capture with extra presence available for vocals and guitars. Compared with the MOTU M4, it is a more focused, compact recording choice, but offers less input/output flexibility and no listed MIDI I/O. The supplied product information does not describe its loopback implementation, so I would confirm the required routing before buying specifically for streaming. It is also a poor match for multi-mic sessions.
Pros:- Dedicated XLR mic preamp and Hi-Z input cover common solo vocal and instrument setups.
- 120 dB dynamic range is specified for its converters.
- Air mode can add presence to vocals and guitars.
- Included recording software and plugins support a starter production workflow.
Cons:- Its one XLR preamp limits simultaneous microphone recording compared with the MOTU M4.
- The supplied product details do not specify loopback functionality or its routing controls.
- The focused input layout offers less flexibility for multi-source streaming and recording.
Best for: Solo singers, guitarists, and streamers who want one mic preamp plus an instrument input in a compact recording setup.
Not ideal for: Creators who need multiple mic preamps, more than two recording inputs, MIDI connections, or clearly specified onboard loopback routing.
- Connectivity:USB-C
- Channels:2
- Inputs:1 XLR mic preamp; 1 Hi-Z instrument input
- Maximum sample rate:192 kHz
- Dynamic range:120 dB
- Compatible devices:Microphone, instrument, computer, headphones, studio monitors
- Supported operating systems:Mac OS, Windows OS, iOS
- Dimensions:3.78 x 5.63 x 1.83 in
Our verdict“Choose the Scarlett Solo if your stream or recording centers on one mic or instrument, but verify loopback support and skip it for multi-mic work.”
MAONO PS22 Lite USB Audio Interface for Recording, Guitar, Vocals, and Streaming
The MAONO PS22 Lite puts loopback routing at the center of its case: its included ProStudio software provides virtual channels and loopbacks, giving streamers routing options beyond a basic direct-monitoring path. A two-channel layout, up to 56 dB of mic-preamp gain, and 48 V phantom power make it usable with dynamic and condenser microphones, while 24-bit/192 kHz recording leaves room for ordinary recording tasks too. Compared with the iRig Stream, the PS22 Lite is more oriented toward microphone recording and software routing than portable stereo RCA capture. That software dependence is also its main compromise: setup may require selecting MAONO’s ASIO driver, and buyers who want a simple hardware-only workflow may prefer another option. Check device compatibility for the planned routing setup.
Pros:- ProStudio software includes virtual channels and loopback routing.
- Up to 56 dB of preamp gain and 48 V phantom power support a range of microphones.
- Records at up to 24-bit/192 kHz.
- The listed operating-system compatibility spans Android, ChromeOS, Windows, iOS, and macOS.
Cons:- Software setup may require selecting the MAONO ASIO driver.
- The two-channel design limits simultaneous sources compared with the MOTU M4.
- Loopback routing depends on software configuration rather than a described hardware loopback control.
Best for: Streamers and home-recording beginners who want virtual channels and loopback routing alongside a mic input and phantom power.
Not ideal for: Creators who want a plug-and-play hardware-only workflow, dedicated stereo RCA capture, or a loopback setup that avoids audio-driver configuration.
- Connectivity:USB
- Channels:2
- Maximum sample rate:192 kHz
- Recording resolution:24-bit
- Dynamic range:106 dB
- Microphone preamp gain:Up to 56 dB
- Phantom power:48 V
- Compatible operating systems:Android, ChromeOS, Windows, iOS, macOS
Our verdict“Choose the PS22 Lite if software-based virtual channels are central to your stream, and skip it if you want routing without driver setup.”
PIYONE Q2 2×2 USB-C Audio Interface, 24-bit/192 kHz
The PIYONE Q2 is a straightforward choice for a small streaming setup that needs two combo inputs and an explicitly listed direct-monitoring and loopback feature set. Both inputs accept XLR/TRS connections, with 48 V phantom power and Hi-Z support extending the range of microphones and instruments it can handle. Unlike the MAONO PS22 Lite, whose loopback is described through software virtual channels, the Q2 lists loopback alongside direct monitoring without naming an extra routing application. That simplicity is appealing, though the supplied details don’t explain loopback controls or routing behavior. Its two-channel limit also leaves less room than the MOTU M4 for a larger setup, and the product data gives mixed compatibility signals: Windows, Mac, and iOS are listed, but another note emphasizes Windows.
Pros:- Two XLR/TRS combo inputs accommodate microphones and other audio sources.
- 48 V phantom power and Hi-Z support broaden input compatibility.
- Direct monitoring and loopback are both listed features.
- USB-C connection and driver-free operation are specified for Mac and PC.
Cons:- Two channels restrict expansion compared with the MOTU M4.
- The operating-system information is inconsistent, so iOS and other device support should be confirmed.
- The supplied description does not explain how loopback routing is controlled.
Best for: Small podcast or streaming setups that need two XLR/TRS inputs, phantom power, and a listed loopback feature without a larger interface.
Not ideal for: Multitrack recording setups, buyers who need four or more inputs, or anyone who requires clearly documented compatibility and loopback controls before purchase.
- Channels:2
- Connectivity:USB-C
- Maximum sample rate:192 kHz
- Recording resolution:24-bit
- Inputs:Two XLR/TRS combo jacks
- Phantom power:48 V
- Monitoring:Direct monitoring and loopback
- Headphone jack:3.5 mm
- Warranty:2-year limited
Our verdict“Choose the PIYONE Q2 for a compact two-input setup with listed loopback, but confirm device support and routing details before relying on it.”
MAONO E2 Gen2 Podcast Equipment Bundle Audio Interface
The MAONO E2 Gen2 is aimed at creators who want loopback as part of a ready-to-stream mixer, not just a way to route computer audio. Its two XLR inputs with up to 60 dB of gain suit a host and guest, while the eight customizable effect buttons, pitch and reverb options, mute control, and monitoring make live shows easier to manage. Unlike the more recording-focused MAONO P1, the E2 adds a built-in battery for up to eight hours of portable operation and hands-on sound effects. That flexibility comes with a busier control set, and its 48 kHz maximum sample rate is below the P1’s 192 kHz ceiling. The USB-C connection also does not charge a phone, and the battery may not last through an all-day session.
Pros:- Loopback, monitoring, and one-touch mute support live audio control.
- Two XLR combo inputs with up to 60 dB of gain accommodate a host and guest.
- Built-in 1500 mAh battery supports up to eight hours of portable use.
- Eight customizable sound-effect buttons plus pitch and reverb options add live performance flexibility.
Cons:- Maximum sample rate is 48 kHz, lower than the MAONO P1’s stated 192 kHz.
- USB-C does not provide phone charging or power delivery.
- The feature-rich controls may add unnecessary complexity for basic recording, and battery life may fall short of an all-day session.
Best for: Podcast hosts and mobile streamers who need two XLR microphones, loopback, onboard sound effects, and battery-powered operation for shorter sessions.
Not ideal for: Creators prioritizing high-resolution recording, a simpler setup, or extended sessions without access to power; the MAONO P1 offers a higher stated sample-rate ceiling and a less effects-oriented focus.
- Channels:10
- Microphone inputs:Two XLR combo inputs
- Maximum preamp gain:Up to 60 dB
- Maximum sample rate:48 kHz
- Connectivity:USB-C, Bluetooth, AUX
- Battery:1500 mAh; up to 8 hours of operation
- Compatible devices:Computer, smartphone, tablet
- Dimensions:9.64 × 6.18 × 2.16 in
Our verdict“Choose the E2 Gen2 for portable, effects-rich two-mic streaming with loopback, but choose the MAONO P1 if recording resolution matters more than onboard performance controls.”
MAONO P1 USB Audio Interface with 70 dB Gain
The MAONO P1 makes the strongest case here for creators who want loopback in a compact recording interface rather than a battery-powered podcast mixer. It supports 24-bit/192 kHz recording, up to 70 dB of gain, auto gain, and direct monitoring, giving it a higher stated recording ceiling than the MAONO E2 Gen2, whose focus is portable operation and built-in performance effects. Its zinc-alloy housing and tilted control surface suit a small desk or a mobile recording setup, while support for computers and mobile devices broadens where it can be used. The tradeoff is less emphasis on onboard sound effects than the E2, and some routing and effects depend on ProStudio2 software. The listed frequency response specifies only 20 kHz, without a range.
Pros:- Supports recording up to 24-bit/192 kHz with up to 70 dB of gain.
- Loopback, auto gain, direct monitoring, and independent mute controls support recording and streaming workflows.
- Supports computer and mobile-device connections, including simultaneous computer and phone or iPad connections.
- Compact zinc-alloy housing provides a durable build with a tilted control surface.
Cons:- Some routing and effects features rely on ProStudio2 software.
- The listed frequency response gives only a 20 kHz figure, not a full range.
- It lacks the E2 Gen2’s built-in battery and customizable sound-effect buttons.
Best for: Musicians, podcasters, and streamers who want a compact loopback interface with high stated recording resolution, strong input gain, and computer or mobile-device compatibility.
Not ideal for: Live podcast hosts who want a battery, customizable physical sound-effect buttons, or a standalone mixer-style workflow; the MAONO E2 Gen2 is better suited to those needs.
- Channels:2
- Maximum sample rate:24-bit/192 kHz
- Maximum gain:70 dB
- Inputs:Microphone, guitar, bass, PC, Mac, smartphone, iPad
- Connectivity:USB
- Housing:Zinc-alloy metal
- Supported operating systems:Android, ChromeOS, Windows, iOS
- Dimensions:5.9 × 5.98 × 3.46 in
Our verdict“Pick the P1 for compact, high-resolution loopback recording across computer and mobile setups, but favor the E2 Gen2 for battery-powered streaming with onboard effects.”
How We Picked
I ranked these interfaces by how well their loopback-related features fit real recording and streaming workflows, rather than by sample-rate figures alone. I weighed the number and type of inputs and outputs, how readily each design supports combining computer playback with live sources, and the usefulness of onboard monitoring and controls. Portability, device compatibility, and whether a model is aimed at stereo mobile capture, a basic home studio, or a podcast setup also shaped its position.
The ranking favors options that can cover more than one common use without making setup unnecessarily complex. The MOTU M4 leads for its broader I/O and monitoring utility; the Zoom AMS-24 earns a distinct place for stream-focused operation. Single-input, compact, and bundle-style products sit lower for general-purpose use, not because they cannot fit a buyer’s needs, but because their narrower formats make them less adaptable across the full range of loopback setups. Where products have similar stated formats, I treat their controls, intended use, and connection flexibility as meaningful differences rather than assuming the specifications tell the whole story.

Factors to Consider When Choosing Audio Interfaces With Loopback
Loopback can refer to different routing methods, so I’d start by mapping the sound sources you need in one session. The best interface is not automatically the one with the most inputs or the highest resolution; it is the one that can send the right mix to your recording or streaming app with manageable monitoring and connections.
Map Every Source You Need to Capture
Write down every source that must reach the stream or recording: microphone, instrument, game or desktop audio, call audio, and any playback from a phone. Then distinguish between sources that need separate tracks and those that can be combined into a stereo mix. A two-input interface may be enough for one mic plus an instrument, yet feel limiting if you want two microphones and independent control of computer playback. Buyers often count physical inputs but forget that software channels and loopback routing can have separate limits. If you expect to add a co-host or extra device, leave room in the routing plan before choosing a compact model.
Check How Loopback Is Routed
Do not assume that every product described as suitable for streaming offers the same loopback path. Some setups rely on routing inside the interface’s control software, while others use dedicated controls or a stereo capture workflow; the practical difference is how easily you can balance sources and send them to the right app. Check whether computer playback can be captured without also recording monitoring audio or creating a feedback loop. A simple combined mix can be convenient for a live stream, but separate channels give more editing control afterward. Verify the routing behavior for your operating system and intended recording or broadcast software before buying.
Choose Between a Live Mix and Separate Tracks
A live mix is a good fit when you need a ready-to-broadcast blend of voice and computer audio. Separate tracks are more useful when you want to adjust the microphone, music, or remote guest after recording. These goals can point to different devices even when both support loopback. A common mistake is to prioritize a quick one-button workflow, then discover that the saved recording cannot be remixed. Decide whether speed during a live session or flexibility in post-production matters more, and check how the interface and software expose each source.
Match Inputs to Microphones and Instruments
Count the inputs you need at the same time, not just the kinds of sources you own. XLR microphones, guitars, line-level devices, and stereo phone outputs can require different input types or cabling. If you record guests in the same room, two mic inputs may be more useful than extra virtual channels; if you stream alone, a compact stereo-oriented unit may cover the job with less equipment. Gain range matters for quieter microphones, but a high gain figure alone does not tell you how the interface behaves with your mic. Check phantom power, instrument input support, and connector layout against your actual gear.
Plan for Devices, Power, and Portability
A setup that works on a desktop computer may need different cables or power arrangements when moved to a phone or tablet. Confirm compatibility for the exact devices you plan to connect, including the required USB or Lightning connection, rather than relying on the interface’s connector label alone. A compact interface is easier to carry, but smaller controls can be less convenient during a live session. Mobile creators should also account for power needs and whether the connected device can run the interface reliably. If the unit will stay on a desk, physical size matters less than clear monitoring and accessible controls.
Pay More for Capabilities You Will Use
Spending more makes sense when you need extra I/O, clearer metering, more flexible routing, or a setup that can grow with additional sources. It makes less sense to pay for channels or advanced controls that will remain unused in a one-mic stream. Bundles can simplify a voice-focused setup, but check which functions are built into the interface and which depend on included accessories or software. A beginner may benefit more from a straightforward workflow than from a dense control panel. Compare the time saved during setup with the flexibility you gain, not just the number of features listed.
Frequently Asked Questions
Can I use loopback to record computer audio and my microphone at the same time?
Yes, if the interface’s routing and your recording software can receive both sources together. Some workflows combine them into one stereo feed, while others let you keep the microphone and computer audio on separate channels. Separate tracks are more flexible for editing, but they may require extra setup in the interface control panel or software. Before buying, confirm what the device sends to your preferred app and whether the mix can be monitored without feeding back into itself.
Do I need a loopback interface if my streaming software already captures desktop audio?
Not always. Software capture may be enough when your computer is the only playback source and you do not need to combine audio from external devices. An interface with loopback can help when you want hardware monitoring, a physical microphone connection, or audio from a phone or other source in the same session. It can also make routing more consistent across apps, depending on the interface and operating system. Compare your current software workflow with the interface’s routing options before adding hardware.
Is a stereo streaming interface enough for podcasting?
It can work for a solo host who mainly needs a microphone and computer or phone playback, especially if a finished stereo mix is acceptable. It may be restrictive for two in-person hosts, separate guest microphones, or recordings that need independent tracks for editing. Check the number of simultaneous mic inputs and whether the device exposes sources separately to your software. The iRig Stream is more focused on stereo capture and device flexibility, while a multi-input interface is a better fit when the podcast setup may expand.
Should I choose the MOTU M4 or Zoom AMS-24 for streaming?
I’d favor the MOTU M4 when broader I/O and useful metering matter alongside streaming, especially if the interface will also support recording or multiple connected sources. The Zoom AMS-24 makes more sense for buyers who want a format geared toward streaming operation and do not need the same general-purpose emphasis. Your choice should hinge on how many physical sources you connect and how much control you want over the mix. Check the routing steps for your software, since an interface that suits one broadcast workflow may not be the easiest fit for another.
What should I check before connecting an interface with loopback to a phone?
Confirm the exact phone connection, operating-system compatibility, and any adapter or cable required for the interface. Also check whether the interface needs external power or draws power from the phone, since that can affect session length and reliability. Make sure your recording or streaming app accepts the interface as an audio source and can capture the intended stereo or multichannel feed. A model with broad device compatibility, such as the iRig Stream, is designed with mobile use in mind, but the specific phone and connection still need to match.
Conclusion
For the best overall fit, I’d choose the MOTU M4 if you want loopback alongside broader I/O and a setup that can serve streaming and recording. For a stream-focused workflow, the Zoom AMS-24 is the more targeted alternative; for best value in a straightforward home-studio setup, compare the Focusrite Scarlett Solo and the MAONO PS22 Lite against the inputs and routing your sessions actually need. Beginners who want a familiar two-input format can start with the Scarlett 2i2 4th Gen, while mobile creators should look at the iRig Stream for stereo capture and device flexibility. Choose the MAONO E2 Gen2 or MAONO P1 for a more voice- and podcast-oriented setup, and skip those narrower options if you need adaptable multi-source routing. The right pick comes down to whether you need a clean live mix, separate tracks, mobile connections, or room to add more sources.
