Buy the Wave XLR if you stream or record alone and want the gain problem to simply not exist: 75 dB of range, -130 dBV EIN at 60 dB of gain, Clipguard to catch a shout, and capacitive tap-to-mute. Buy the Scarlett 2i2 (4th Gen) if there is any chance of a second microphone, an instrument, or recording outside one piece of software — 69 dB is already more than any microphone here needs, and two inputs is the difference between adding a guest and buying a second box.
These two are not really competing for the same job, which is why the comparison is useful. One is a single-purpose streaming front end; the other is the default two-input interface in home recording. Both solve the gain problem that defeats cheaper boxes.
75 dB versus 69 dB is not the decision
Both figures clear every microphone on this site. An SM7B at -59.0 dBV/Pa wants roughly 60 dB for a conversational voice; the Scarlett's 69 dB leaves 9 dB of margin and the Wave XLR's 75 dB leaves 15 dB. Past a certain point extra gain stops being useful, and both are past it.
Where the Wave XLR's headroom does earn its keep is at the extremes: a very quiet speaker, a microphone held further back than usual, or a low-output ribbon. If that is you, the extra 6 dB is real. For everyone else, this is a feature comparison, not a specification one.
What the Wave XLR gives you that the Scarlett does not
- Clipguard. A second, lower-gain capture path that catches a transient which would otherwise clip. That is a genuine insurance policy for live streaming, where there is no second take.
- Capacitive tap-to-mute on the top surface, with a visible indicator. Better than a key bind, and the kind of detail that only exists on a tool built for one job.
- Software mixing built around streaming. Wave Link routes your microphone, game audio, chat and music as separate sources, which is what a stream actually needs.
- `-130 dBV` EIN published at a stated gain setting, which is more specific than most manufacturers manage.
What the Scarlett gives you that the Wave XLR does not
- A second microphone input. The most-regretted omission in home recording. A guest, a co-host or a second position for an instrument microphone all need it.
- Instrument inputs. Both combo inputs take a guitar or bass directly. The Wave XLR has no instrument input at all — see best audio interfaces for guitar if that matters.
- `192 kHz` conversion and `120 dB` dynamic range without a caveat. The Wave XLR's 120 dB figure is conditional on Clipguard being engaged; without it the published figure is 100 dB.
- Software independence. The Scarlett is a class-compliant interface that behaves identically in any DAW. The Wave XLR's routing lives in Elgato's software, which is a strength if you want that workflow and a constraint if you do not.
- Air mode, a fixed upper-midrange lift that suits speech.
Both boxes, plus the podcast-specific option
Elgato Wave XLR
Top pickElgato · The most gain of any single-channel box, built for streaming
The right box if you stream or record alone with a low-output dynamic and want the gain problem to simply not exist. It is not a general-purpose interface, and it is the wrong buy if you also record instruments.
Why it is here
- `75 dB` of gain drives an SM7B with room to spare and no booster, which is the single most common streaming problem solved outright
- Clipguard catches a shout that would otherwise clip the take
- Capacitive tap-to-mute on the top surface, which is genuinely better than reaching for a key bind
What it costs you
- One microphone input, so a co-host needs a second unit
- The mixing lives in Elgato's software, so it is a Wave Link setup rather than a neutral interface
- No MIDI, no line inputs, no instrument input
Focusrite Scarlett 2i2 (4th Gen)
Focusrite · The most gain per dollar in a two-input box
The default answer for someone buying an SM7B or PodMic: it supplies enough clean gain that you never need a booster, which makes it the cheaper total purchase even when it is not the cheaper box. Look elsewhere only if you need MIDI or four outputs.
Why it is here
- 69 dB is the most gain of any interface at this price, and enough for an SM7B with headroom to spare
- 120 dB dynamic range means the converters are not the weak link
- Two inputs, so a second person does not mean a second purchase
What it costs you
- Air mode is a fixed voicing, not an EQ you can dial
- Plastic-and-metal build feels less solid than the SSL or Audient competition
- No MIDI, which matters if you also play keys
Focusrite Vocaster One
Focusrite · A solo host who does not want to set levels
The pick for a solo podcaster who wants the gear to get out of the way. If you record music as well as speech, a general-purpose interface with the same gain is the better buy.
Why it is here
- `70 dB` of gain means any microphone on this site works without a booster
- Auto Gain removes the single most common beginner mistake in one button press
- Stereo loopback plus phone and camera connections, which is the actual podcast workflow
What it costs you
- 24-bit / 48 kHz only, and no instrument input — it is a speech box and nothing else
- The three Enhance presets are printed into the recording
- One microphone input; a co-host means the Vocaster Two
The third option worth knowing about
If you are a solo podcaster rather than a streamer, the Focusrite Vocaster One sits between these two in intent: 70 dB of gain, Auto Gain to set your level, stereo loopback, and phone and camera connections. It is as narrow a tool as the Wave XLR but pointed at speech recording rather than at live streaming. Best audio interfaces for podcasting ranks the whole field, and best audio interfaces for streaming does the same for streams.
Which to buy
- You stream, alone, and already use Elgato software: Wave XLR. The gain headroom, Clipguard and tap-to-mute are built for exactly that.
- You record anything other than your own voice into one app: Scarlett 2i2. The second input and the instrument inputs matter more than 6 dB you will not use.
- You might add a co-host: Scarlett 2i2, or a Wave XLR per person if you are committed to Wave Link.
- Your microphone is unusually quiet: Wave XLR, for the 75 dB.
