The Best Audio Interfaces for Singers

The best audio interface for singers is one with a clean, quiet microphone preamp, enough gain for your mic, reliable phantom power and rock-solid low-latency monitoring so you can sing in time with yourself. You almost never need more than one or two inputs for solo vocals, so spend your money on preamp quality and stable drivers rather than channel count.

Quick answer: For most home singers, a tidy 1- or 2-input USB interface with one good preamp is ideal. The Focusrite Scarlett Solo, Audient EVO 4, Universal Audio Volt 2 and PreSonus Studio 24c are all dependable choices. Pick based on how much gain your microphone needs and whether you want extra colour or extra inputs.

What an audio interface for singers actually needs

Recording a voice is simpler than recording a band, so focus on the few things that genuinely affect a vocal take:

• Clean preamps with enough gain. Quiet, sensitive dynamic mics like the Shure SM7B want a lot of gain. If you use one, look for an interface with high gain headroom or a built-in boost mode.
• Phantom power (+48V). Required for condenser microphones, which are the most common choice for home vocals. If you are unsure how this works, read what is phantom power.
• Low-latency monitoring. You need to hear yourself with no delay while you sing. Direct monitoring or very low buffer settings make this comfortable.
• A good headphone output. Singers monitor on closed-back headphones, so the headphone amp needs to drive them loudly and cleanly.
• Stable drivers. A class-compliant or well-supported interface that does not drop out mid-take matters more than any spec sheet.

How many inputs do you need?

For solo vocals, one mic input is enough. Choose two inputs if you also play guitar or piano while singing, record duets, or want room to grow. Going beyond two channels rarely helps a singer and usually just adds cost.

Connection and platform

USB is the standard for home setups and works on Mac, Windows, and most tablets and phones with the right adapter. Confirm the interface is class-compliant if you plan to record on an iPad. For wiring everything up, see our walkthrough on how to set up an audio interface.

The best audio interfaces for singers

Focusrite Scarlett Solo

The Scarlett Solo is the classic single-vocalist interface: one mic preamp with phantom power, one instrument input, and a headphone output, in a compact and very well-supported package. The preamps are clean and easy to set, and the bundled software gets you recording quickly. It is a safe default for anyone tracking one voice at a time.

Audient EVO 4

The EVO 4 punches above its size thanks to its Smartgain feature, which automatically sets a sensible input level for you — genuinely helpful if you are new to setting gain. It has two inputs, good converters for the class, and a clean monitoring path. A strong pick for beginners who want less fuss.

Universal Audio Volt 2

The Volt 2 adds an optional vintage preamp mode that lends a subtle, flattering warmth to vocals, which many singers like. It has two inputs, solid build quality, and dependable drivers. Choose it if you want a touch of analogue character baked into your tracking chain.

PreSonus Studio 24c

The Studio 24c offers two combo inputs with plenty of clean gain, high-resolution converters, and a generous software bundle. It is a great-value two-input option for a singer who also wants to record an instrument or a second vocalist. For a closer look, see our USB mic vs audio interface comparison to decide if an interface is right for you at all.

For demanding dynamic mics: high-gain options

If you sing into a low-output dynamic like the SM7B, prioritise gain. The Volt 2 and similar interfaces with extra boost handle these mics better than entry-level units. Otherwise, an inline gain booster solves the problem on quieter interfaces.

Getting clean vocal recordings once it is connected

The interface is only part of the chain. Set your gain so loud passages peak well below clipping, monitor on closed-back headphones, and treat your room. Our guides on how to record vocals at home and audio interfaces cover the rest of the workflow, from mic placement to gain staging.

Frequently asked questions

Do singers need a 2-channel interface?

Not for solo vocals — a single mic input is enough. Choose two inputs only if you record an instrument alongside your voice, track duets, or want headroom to expand later.

Will any interface power a condenser mic?

You need an interface with +48V phantom power, which most modern USB interfaces include. Check the spec before buying, as a few instrument-only or guitar-focused interfaces omit it.

What interface works with the Shure SM7B?

The SM7B needs a lot of clean gain. Pick an interface with high gain headroom such as the Volt 2, or add an inline gain booster to a lower-gain interface to drive it properly.
