How we ranked these audio interfaces

Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: 8 channel USB audio interface

Count the inputs you record at once

Input count decides how many sources you record together. The Behringer FLOW 8 and the Audient EVO 8 each give 8 inputs, while the MOTU UltraLite-mk5 gives 18 x 22 USB audio. The Solid State Logic SSL 12 is a 12-in and 8-out USB audio interface. If you record 8 sources at once, an 8-input interface covers the session, and an interface with more inputs covers more sources.

Check preamps, sample rate, and bit depth

Preamps, sample rate, and bit depth change what an interface captures. The Behringer FLOW 8 gives 2 Midas microphone preamps with 48 V phantom power, and the Audient EVO 8 gives 4 EVO mic preamps. The Audient EVO 8 gives a 96 kHz maximum sample rate, while the Solid State Logic SSL 12 gives 192 kHz and 32-bit converters. Compare preamp count and converter figures against the sources you record.

Look at controls, software, and weight

Controls and software change how you run a session. The Behringer FLOW 8 uses 60 mm channel faders, 2 FX processors, and the FLOW app for Bluetooth remote control. The Audient EVO 8 uses USB 2.0 with bundled software for Mac and Windows, and the MOTU UltraLite-mk5 uses CueMix 5 and Performer Lite software. Weight matters too: the Behringer FLOW 8 weighs 3.1 lb, the Audient EVO 8 weighs 1 lb, the Solid State Logic SSL 12 weighs 3.2 lb, and the MOTU UltraLite-mk5 weighs 2.9 lb.
