# Best Audio Interface 2026: 10 Ranked, and Where the Spec Sheets Disagree Source: https://www.ranked10.co.uk/tech/best-audio-interfaces Published: 2026-09-18 | Updated: 2026-09-19 | Prices checked on Amazon UK on 2026-09-17 On these ten audio interface listings, the fields buyers lean on hardest are the ones filled in with the least care. The Focusrite Scarlett Solo 4th Gen (£119) prints 'Frequency Response: 96 KHz' in the same block where it declares 'Maximum Sample Rate: 192 KHz', and the highlight block on that same page says 24-Bit/192kHz. The Behringer UMC404HD (£89) repeats the split exactly: 96 KHz in one field, 192 KHz in the next. Meanwhile 'Number of Channels' tells you very little. The Scarlett Solo's own highlight reads '1 XLR Mic Preamp, 1 Hi-Z Instrument Input' underneath a spec sheet claiming 2 channels. The Arturia MiniFuse 2, with a 2 in its own name, lists 'Number of Channels: 1' and a 48 kHz maximum. In short, every figure below is quoted from the listing it belongs to — contradictions included. We ranked ten of the best audio interface options on Amazon on three checkable criteria: whether the published specs agree with each other, how many ratings stand behind the star score, and price per input. Where two numbers on the same listing disagree, we name both. ## The ranking ### 1. Focusrite Scarlett Solo 3rd Gen USB-C Audio Interface - Price: £77.00 | Amazon rating: 4.7 from 29,034 ratings - Full review: https://www.ranked10.co.uk/tech/best-audio-interfaces/focusrite-scarlett-solo-3rd-gen - Buy on Amazon: https://www.amazon.co.uk/dp/B07QR6Z1JB?tag=ranked10-21 The best-supported audio interface here: 29,034 ratings at 4.7, and two sample-rate fields that agree with each other. This tops the list on volume of evidence. 29,034 ratings at 4.7 is roughly six times the review base of anything else here, and it is one of the few audio interface listings in this group whose sample-rate fields match: 192 KHz under Frequency Response, 192 KHz under Maximum Sample Rate. The highlight block — 24-Bit/192kHz, 56dB gain range, Air mode — lines up with that. In practice, the single XLR input carries a 56dB gain range and a switchable Air mode for added presence on vocals. The second input is Hi-Z for guitar and bass, with a high-headroom design the listing says avoids clipping. Two balanced outputs and a high-powered headphone output handle playback, and the box weighs 349 g and runs off USB-C. That said, do not buy it for a two-person podcast. The highlight reads '1 XLR Mic Preamp, 1 Hi-Z Instrument Input' while the channel field says 2 — those two figures are describing different things. No MIDI I/O appears in the listed inputs, and the operating system field names Linux and macOS while the highlight also claims Windows, so check your platform before ordering. Pros: 29,034 ratings at 4.7 — by far the largest review base of the ten; 192 KHz appears in both the frequency response and maximum sample rate fields, so nothing contradicts itself; 56dB gain range plus a switchable Air mode on the mic preamp; 24-bit/192kHz converters, two balanced outputs and a high-powered headphone output; £77 — £42 cheaper than the 4th Gen Solo at £119 Cons: 1 XLR mic preamp and 1 instrument input, despite a channel field reading 2; No MIDI I/O listed; inputs are XLR and instrument only; Operating system field lists Linux and macOS but omits Windows, which the highlight claims; One mic preamp rules out recording two microphones at once ### 2. PreSonus Studio 24c USB-C Audio Interface - Price: £125.75 | Amazon rating: 4.6 from 4,514 ratings - Full review: https://www.ranked10.co.uk/tech/best-audio-interfaces/presonus-studio-24c - Buy on Amazon: https://www.amazon.co.uk/dp/B07L9MWWDK?tag=ranked10-21 Two XMAX-L mic preamps and a full software bundle for £125.75, with 192 KHz printed in both sample-rate fields. Two mic preamps is the headline, and the spec sheet backs it: 2 channels, XLR, 1/4 inch and RCA inputs, and 192 KHz in both the frequency response and maximum sample rate fields. 4,514 ratings at 4.6 is the third-deepest base on this page. In practice, the two XMAX-L preamps cover vocals and instruments, with high-headroom instrument inputs for guitar and bass. Per-input metering shows your levels, and a Mix control blends the analogue inputs against computer playback while you track. It is bus-powered over USB-C, weighs 454 g, and ships with Studio One Artist and Ableton Live Lite, which is worth noting if you own no DAW yet. However, no MIDI I/O is listed, and 2 in / 2 out is the ceiling. If you are shopping for an audio interface for podcasting with two hosts, this meets the minimum. If you need four microphones for a drum kit, it does not, and the £89 Behringer UMC404HD has four combination XLR/TRS inputs. The country-of-origin field reads Germany, which is an oddity in a PreSonus listing rather than a specification. Pros: Two XMAX-L mic preamps for £125.75; 192 KHz in both the frequency response and maximum sample rate fields; XLR, 1/4 inch and RCA inputs accepted; Ships with Studio One Artist and Ableton Live Lite as a bundle; 2-year manufacturer warranty stated in the listing Cons: No MIDI I/O anywhere in the listed connections; 2 in / 2 out, so a four-mic session is out; Country-of-origin field reads Germany, which does not match the brand's usual listings; Software bundle adds setup time if you already own a DAW ### 3. Focusrite Scarlett 2i2 4th Gen USB-C Audio Interface - Price: £164.00 | Amazon rating: 4.7 from 2,626 ratings - Full review: https://www.ranked10.co.uk/tech/best-audio-interfaces/focusrite-scarlett-2i2-4th-gen - Buy on Amazon: https://www.amazon.co.uk/dp/B0C5JRTS3Y?tag=ranked10-21 The priciest pick at £164, and the only listing here that names Auto Gain and Clip Safe. At £164 this is the most expensive item on the list, backed by 2,626 ratings at 4.7. It is also the only listing here that names Auto Gain and Clip Safe, which set your level for you and stop a take clipping. Its two sample-rate figures do not contradict each other, although the frequency response field reads 20,000 Hz — that is audio bandwidth, the top of human hearing, not the 192 KHz conversion rate quoted beside it. Crucially, you get 2 mic preamps and 2 Hi-Z instrument inputs, a 120dB dynamic range, and Air mode on both channels. The converters are described as the same ones used in Focusrite's flagship interfaces. The software covers Pro Tools Intro+, Ableton Live Lite, Cubase LE and the Hitmaker Expansion, which is a lot of included tooling for the money. The catch is price per input. £164 buys 2 in / 2 out; the £89 Behringer UMC404HD buys 4 combination XLR/TRS inputs for £75 less. Meanwhile the operating system field lists Windows only, while the supported software list names GarageBand and Logic Pro, so macOS support is implied rather than stated. If you record alone, one source at a time, you are paying for headroom you may never use. Pros: Auto Gain and Clip Safe — features no other listing in this group names; 120dB dynamic range, the highest figure quoted here; 2 mic preamps and 2 Hi-Z instrument inputs; Pro Tools Intro+, Ableton Live Lite, Cubase LE and Hitmaker Expansion included; 192 KHz maximum sample rate Cons: £164 is the highest price of the ten; Frequency response field reads 20,000 Hz, which is bandwidth rather than a conversion rate; Operating system field lists Windows only, despite the software list naming GarageBand and Logic Pro; Costs £75 more than a four-input Behringer while offering half the inputs ### 4. Behringer UMC202HD 2x2 USB Audio Interface - Price: £54.70 | Amazon rating: 4.5 from 3,378 ratings - Full review: https://www.ranked10.co.uk/tech/best-audio-interfaces/behringer-umc202hd-audio-interface - Buy on Amazon: https://www.amazon.co.uk/dp/B00SAV0VP0?tag=ranked10-21 The budget audio interface of the group at £54.70, with 3,378 ratings behind it. This is the budget audio interface here: £54.70, with 3,378 ratings at 4.5, the second-largest review base on the page. Frequency response and maximum sample rate both read 192 KHz, so those two fields agree. On the desk, two combination XLR/TRS inputs take microphones or instruments, a +48V switch feeds condenser mics, and 1/4 inch TRS outputs feed monitors. Direct monitoring is switchable and described as zero-latency, which matters when you track a vocal against a backing track. Connection is USB 2.0 and the unit weighs 540 g. Even so, 2 in / 2 out is all you get. There is no MIDI and no RCA playback, and no analogue inserts for outboard gear. The UMC204HD at £65 adds RCA playback and two inserts for £10 more. Buy this one only if two channels is genuinely enough for how you record. Pros: £54.70 — the lowest price of the ten; 3,378 ratings at 4.5, the second-deepest review base here; 192 KHz in both the frequency response and maximum sample rate fields; Two combination XLR/TRS inputs with +48V phantom power; Switchable zero-latency direct monitoring for tracking Cons: No MIDI I/O, no RCA playback and no analogue inserts; Only 2 in / 2 out, so multi-mic sessions are out; No included DAW is listed in the bundle; £10 more buys the UMC204HD with four outputs instead of two ### 5. Behringer UMC204HD 2x4 USB Audio/MIDI Interface - Price: £65.00 | Amazon rating: 4.6 from 2,312 ratings - Full review: https://www.ranked10.co.uk/tech/best-audio-interfaces/behringer-umc204hd - Buy on Amazon: https://www.amazon.co.uk/dp/B00SAV96JM?tag=ranked10-21 £65 for 2 ins and 4 outs, including two analogue inserts the cheaper Behringer lacks. For £10 more than the UMC202HD you get double the outputs: 2 in / 4 out at £65, with 2,312 ratings at 4.6. Both sample-rate fields read 192000 Hz and 192 KHz, so this listing is internally consistent where the UMC404HD is not. The two combination XLR/TRS inputs run through Midas-designed preamps. Playback covers both 1/4 inch TRS and RCA, and there are 2 analogue inserts for compressors, gates or EQ. This USB audio interface weighs 620 g and is bus-powered over USB 2.0. Worth noting: the product name says Audio/MIDI, but no MIDI I/O appears anywhere in the listed inputs or connections, only XLR and line. Check that before buying if MIDI is the reason you clicked. And if you need four mic preamps rather than two, this is not the box — that is the UMC404HD. Pros: £65 for 2 inputs and 4 outputs; Two analogue inserts for outboard compressors, gates or EQ; Playback via both 1/4 inch TRS and RCA; 192000 Hz frequency response and 192 KHz maximum sample rate agree; 2,312 ratings at 4.6 Cons: Product name says Audio/MIDI, but no MIDI I/O is listed in the connections; Only 2 mic preamps; No included software bundle is stated; £24 less than the UMC404HD, which doubles the input count ### 6. Focusrite Scarlett Solo 4th Gen USB-C Audio Interface - Price: £119.00 | Amazon rating: 4.5 from 2,725 ratings - Full review: https://www.ranked10.co.uk/tech/best-audio-interfaces/focusrite-scarlett-solo-4th-gen - Buy on Amazon: https://www.amazon.co.uk/dp/B0C5JSHP7M?tag=ranked10-21 The listing that shows the problem: 96 KHz in one spec field and 192 KHz in the next, on the same page. £119, with 2,725 ratings at 4.5. This is where the spec sheet stops agreeing with itself: 'Frequency Response: 96 KHz' sits directly above 'Maximum Sample Rate: 192 KHz', and the highlight block on the same page states 24-Bit/192kHz. Two of those three numbers cannot both be right. In use, you get one XLR mic preamp and one Hi-Z instrument input, a 120dB dynamic range, Air mode and USB-C. The Easy Start tool walks you through setup. Weight is 408 g, and the software bundle matches the 2i2's: Pro Tools Intro+, Ableton Live Lite, Cubase LE and the Hitmaker Expansion. By contrast with the 3rd Gen Solo at £77, you are paying £42 more for the newer generation, and this listing carries no product warranty field at all while the 3rd Gen states a 3-year warranty. The channel field says 2; the highlight says 1 mic preamp and 1 instrument input. If you need two microphones, neither Solo will do it. Pros: 120dB dynamic range and Air mode on the mic preamp; USB-C connection with the Easy Start setup tool; Same software bundle as the more expensive 2i2: Pro Tools Intro+, Ableton Live Lite, Cubase LE, Hitmaker Expansion; 2,725 ratings at 4.5; Weighs 408 g, the lightest Focusrite here Cons: Frequency response field reads 96 KHz against a 192 KHz maximum sample rate — the listing contradicts itself; One mic preamp and one instrument input, despite a channel field reading 2; No product warranty field listed, while the 3rd Gen states 3 years; £42 more than the 3rd Gen Solo for the same input count ### 7. Audient EVO 4 USB-C Audio Interface - Price: £89.00 | Amazon rating: 4.3 from 1,639 ratings - Full review: https://www.ranked10.co.uk/tech/best-audio-interfaces/audient-evo-4 - Buy on Amazon: https://www.amazon.co.uk/dp/B084BGC5LR?tag=ranked10-21 A 2 in 2 out audio interface with Smartgain, but the lowest rating in this group at 4.3. This is the only 2 in 2 out audio interface in the group rated 4.3 — the lowest of the ten — from 1,639 reviews. Its specs are consistent, though: 96 KHz in both the frequency response and maximum sample rate fields. Smartgain sets input levels for you, which is the feature most home studio audio interface buyers notice first. The two mic preamps offer 58dB of gain, there is a discrete JFET instrument input, and a loopback function routes computer audio back into a stream, which is handy for podcasting and screen recording. Power and data both run over USB-C, and it weighs 360 g according to the bullet points. At the same time, 96 kHz is the ceiling here, not 192. And the listing contradicts itself on physical size: the bullet points say 360 g and 140 x 55 x 60 mm, while the spec table says 600 g and 6.7 x 14 x 6.7 cm. Check the footprint before you buy a stand or a desk shelf for it. Pros: Smartgain sets input levels automatically; Two mic preamps with 58dB of gain; Discrete JFET instrument input; Loopback function for streaming and screen recording; 96 KHz in both sample-rate fields, so no internal contradiction there Cons: 4.3 from 1,639 ratings — the lowest score in this ranking; 96 kHz maximum sample rate, not 192 kHz; Bullet points say 360 g and 140 x 55 x 60 mm while the spec table says 600 g and 6.7 x 14 x 6.7 cm; Only 2 in / 2 out ### 8. Arturia MiniFuse 2 USB-C Audio & MIDI Interface - Price: £104.00 | Amazon rating: 4.6 from 1,180 ratings - Full review: https://www.ranked10.co.uk/tech/best-audio-interfaces/arturia-minifuse-2 - Buy on Amazon: https://www.amazon.co.uk/dp/B09HL3GD7G?tag=ranked10-21 Named 2, listed as 1 channel, and capped at 48 kHz in the spec table. The name says MiniFuse 2. The spec table says 'Number of Channels: 1' and 'Maximum Sample Rate: 48 KHz', and there is no frequency response field at all. The listing carries 1,180 ratings at 4.6 and the price is £104. What the listing does describe is flexible: microphone and instrument inputs, MIDI I/O for synths and controllers, and a software bundle built around Ableton Live Lite with beginner tutorials and ready-made song projects. It comes with a 5-year warranty, the longest stated anywhere in this group. However, that 48 kHz figure is the reason to pause. If you track at 96 kHz or 192 kHz, this is not the box for you. If you need more than one input running at once, the channel field's 1 is a warning. Either way, do not buy on the spec table alone here, because the name and the numbers disagree. Pros: 5-year warranty, the longest stated in this ranking; MIDI I/O for synths, controllers and drum machines; Software bundle built around Ableton Live Lite with tutorials; 1,180 ratings at 4.6; Compact desktop housing Cons: Spec table says 1 channel for a product named MiniFuse 2; 48 KHz maximum sample rate, the lowest here; No frequency response field listed at all; Supported software field names Mac OS only, while the operating system field lists Windows and macOS ### 9. Behringer UMC404HD 4x4 USB Audio/MIDI Interface - Price: £89.00 | Amazon rating: 4.6 from 552 ratings - Full review: https://www.ranked10.co.uk/tech/best-audio-interfaces/behringer-umc404hd - Buy on Amazon: https://www.amazon.co.uk/dp/B00TTX73YA?tag=ranked10-21 Four Midas preamps for £89 — the cheapest route to four XLR inputs, but the thinnest review base at 552. Four Midas-designed mic preamps for £89. That is the pitch, and the spec sheet repeats the same contradiction as the Solo 4th Gen: 'Frequency Response: 96 KHz' alongside 'Maximum Sample Rate: 192 KHz', with 192 kHz resolution claimed in the bullets. In practice, four combination XLR/TRS inputs plus MIDI I/O make this the pick for tracking a drum kit or a four-piece band on a tight budget. The chassis is the biggest here — 41.4 cm deep and 1.2 kg — so it wants real desk space rather than a laptop bag. That said, 552 ratings at 4.6 is the thinnest review base of the ten, less than a fifth of the UMC202HD's. And if you only ever record one source at a time, four inputs is £34 more than you need; the UMC202HD covers that for £54.70. Pros: Four combination XLR/TRS inputs for £89; Four Midas-designed mic preamps; MIDI I/O included, unlike the UMC202HD and UMC204HD; 192 kHz resolution claimed in the product bullets; 4.6 average from 552 ratings Cons: Frequency response field reads 96 KHz against a 192 KHz maximum sample rate; Only 552 ratings — the smallest review base in this ranking; 1.2 kg and 41.4 cm deep, so it needs desk space; No included software bundle is stated ### 10. Universal Audio Volt 1 USB Audio Interface - Price: £107.00 | Amazon rating: 4.5 from 713 ratings - Full review: https://www.ranked10.co.uk/tech/best-audio-interfaces/ua-volt-1-usb-audio-interface - Buy on Amazon: https://www.amazon.co.uk/dp/B09J1V6R6N?tag=ranked10-21 One preamp, a Vintage Mic Preamp mode and a deep plug-in bundle at £107. The Volt 1 is a single-preamp audio interface for recording at £107, with 713 ratings at 4.5. Its channel field says 2, the same loose use of that field you see on the Arturia. Both sample-rate fields read 192000 Hz and 192 KHz, so those agree. The drawing card is Vintage Mic Preamp mode, which colours vocals and instruments. The bundle is unusually deep: Ableton, Melodyne, UJAM's Virtual Drummer, Marshall and Ampeg among others, plus a 30-day UAD Spark trial. It runs on Mac, PC, iPad and iPhone, weighs 544 g, and connects over USB. Either way, one input means one source at a time. The 'Audio Input' field reads 'USB', which is a connection type rather than an input, so read the bullets for the real picture. The fourth bullet is not a specification at all: it is a cross-border shipping disclaimer warning that international products may differ from local ones. If you want two mic preamps, the PreSonus Studio 24c is the better fit. Pros: Vintage Mic Preamp mode for colour on vocals and instruments; Deep software bundle: Ableton, Melodyne, UJAM Virtual Drummer, Marshall, Ampeg, plus a 30-day UAD Spark trial; 192000 Hz and 192 KHz in both sample-rate fields; Works with Mac, PC, iPad and iPhone; 713 ratings at 4.5 Cons: Channel field reads 2, but the model name and the preamp count say one input; Audio Input field reads USB, which is a connection type rather than an input; Fourth bullet is a cross-border shipping disclaimer, not a spec; £107 for a single input, when £125.75 buys two preamps ## Verdict Two picks cover most people. For one mic and one guitar, the £77 Focusrite Scarlett Solo 3rd Gen has the deepest rating base here — 29,034 reviews at 4.7 — and its two sample-rate fields agree with each other. If you need a home studio audio interface with two mic preamps, the PreSonus Studio 24c at £125.75 gives you two XMAX-L preamps and 192 KHz in both sample-rate fields. For four microphones at once, the £89 Behringer UMC404HD is the cheapest route, though its review base is the thinnest at 552; either way, treat its 96 KHz frequency-response field as a typing error, not a ceiling. And if you are starting from nothing, the £54.70 Behringer UMC202HD is the best audio interface for beginners on price, with 3,378 ratings behind it.
