How we ranked these audio interfaces

Every pick ranks in Amazon's best-seller list for its category and has 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: audio interface with dsp

Count inputs and mic preamps first

DSP does not add inputs. The Audient iD2 gives 10 inputs in total, with 2 console mic preamps and 8 channels of ADAT expansion, so it records more sources at once than a box with 2 inputs. The Apollo Twin X Duo USB is a 10 x 6 interface, and the BEACN Studio is an XLR microphone interface. Decide how many microphones and instruments you record at once, then pick the input count that covers them.

Match the DSP to the job

Onboard DSP runs EQ, compression and reverb without plugins or CPU load. The Audient iD2 runs zero-latency DSP FX in hardware, with EQ, compression and reverb, and RoomTune monitor correction. The Apollo Twin X Duo USB runs UAD DSP with Unison preamps for tracking through vintage plugin models. The BEACN Studio runs a DSP mic chain with EQ, Compression, Expander/Gate, Noise Suppression and Low Frequency Enhancement, managed in the BEACN App. Pick the DSP chain that matches the work: hardware FX and monitor correction, tracking through vintage models, or a mic chain for streaming and podcasting.

Check power, outputs and the box

The Audient iD2 runs bus-powered over USB-C on Mac and Windows, with 2 stereo monitor outputs, an assignable monitor control button and dual headphone outputs. The Apollo Twin X Duo USB is a desktop interface for Windows with a built-in talkback mic. The BEACN Studio connects over USB-C with dual PC connections and pairs with a BEACN Mix or BEACN Mix Create for extra control. The Audient includes the RM1 Reference Microphone for RoomTune measurements.
