Detailed Reviews
Focusrite Scarlett 2i2 4th Gen — Best Starter Interface
The Scarlett 2i2 is the world's best-selling audio interface for good reason: transparent preamps with selectable Air mode (brightens high frequencies to mimic ISA transformer preamps), ultra-low noise floor, and an exceptional software bundle including Ableton Live Lite and Antares AutoTune. The 4th Gen adds USB-C and 56dB of gain headroom for dynamic mics.
- Pros: Best starter value, Air preamp mode, excellent software bundle, USB-C, compact
- Cons: 2-in only, no MIDI I/O, no headphone output level knob on base model
Universal Audio Volt 2 — Best for Vintage Sound
The Volt 2's killer feature is its Vintage mode — a built-in hardware emulation of UA's classic 1176 compressor that adds musical saturation and punch to vocals and instruments. No software needed. The preamps are warmer and more characterful than the Scarlett, making it ideal for singer-songwriters wanting immediate analog-style character.
- Pros: 1176 hardware Vintage mode, warm preamp character, built-in 48V phantom, quality build
- Cons: Vintage mode coloring isn't for everyone, less software bundle than Focusrite
FAQ
Q: Do I need an audio interface for USB microphones?
A: No — USB mics plug directly into your computer. Audio interfaces are for XLR microphones, guitars, and instruments with standard audio connections.
Q: What's the difference between 1-in and 2-in interfaces?
A: A 1-in interface records one source at a time. A 2-in interface lets you record two simultaneous sources — for example, a vocal mic and a guitar DI at the same time. For most solo podcasters, 1-in is fine; for musicians, 2-in is the practical minimum.
