Audio Interfaces & Hardware

A reference for the hardware sitting between your mics / instruments and your DAW. Class-compliant USB interfaces work driverless on Mac / Linux / iOS; Win benefits from a vendor ASIO driver (see audio-routing-win-mac for ASIO4ALL when none exists). Audio-over-IP (Dante / AVB / AES67) is the pro install-world counterpart. For USB-MIDI controllers see midi-routing-tools.

USB audio interfaces (home / project studio)

Entry tier ($100-200)

• ★ Focusrite Scarlett Solo / 2i2 / 4i4 (4th gen, 2023-26) — class-compliant USB, great preamps for the price, Hi-Z guitar in. The default budget interface in 2026. Bundles include Ableton Lite + plugin promos.
• ★ MOTU M2 / M4 — class-compliant USB-C; ESS Sabre converters; broadcast-grade meters; arguably better DAC than Scarlett at the same price.
• Universal Audio Volt 2 / Volt 4 / Volt 76 / Volt 476 — class-compliant; built-in 1176-style "Vintage" preamp coloring.
• Audient EVO 4 / EVO 8 / EVO 16 — class-compliant; SmartGain auto-set-the-gain feature; great preamps.
• Behringer UMC202HD / UMC404HD — cheaper alternative; mostly fine, less loved.
