Audient iD4+ MK3

The Audient iD4+ MK3 (formerly the iD44) is a 20-in / 24-out desktop audio interface for the engineer running serious sessions, built around two things most in its class can't offer: built-in RoomTune™ Monitor Correction with the RM1™ in the box, and four tone-shaping Console Mic Preamps with real analogue saturation. It adds hardware-accelerated DSP FX, balanced hardware inserts, 16 channels of ADAT I/O and 32-bit conversion, all over a single USB-C cable: a commercial studio's signal chain on your desktop.

Audient Console Mic Preamp. All 4 preamps use the same fully analogue design found in the flagship ASP8024-HE console: Class-A circuitry and 75 dB of clean gain, enough to drive an SM7B or any dynamic mic without a booster, with a signal path quiet enough for whispered vocals and soft acoustic parts.

Smartgain. Press the button, play your loudest part and the iD4+ sets the level in seconds, with no clipping and optimised headroom for quiet verses and big choruses alike. In stereo pair mode both channels are matched automatically.

Analogue Tone Suite. Real analogue saturation that shapes the sound of the preamp before it reaches your DAW, so recordings arrive sounding like a record, not a demo.

RoomTune™ Monitor Correction, built in, with the RM1™ microphone included. It corrects your room response inside the interface, with zero CPU cost and always on from the moment your monitors power up. The factory-calibrated RM1™ Reference Microphone is in the box: guided setup takes under twenty minutes, stores two profiles (one per pair of monitors) and works system-wide.

Balanced hardware inserts. Balanced send and return on channels 1 and 2 put your outboard compressor or EQ in the signal path before your DAW, so its colour lands on the track. The return also works as a line input straight to the converters, bypassing the preamp.

Digital expansion. 16 channels of ADAT in and 16 out: track a full band or a complete drum kit alongside the four mic preamps (20 inputs in total) and send audio to outboard summing, multi-room monitoring or hardware effects racks. With word clock output.

Hardware-accelerated DSP FX. EQ, compression and reverb processed on the interface itself, with zero latency and no CPU cost: fix a dull vocal or a boomy guitar on the way in and add reverb to the headphones for a more inspiring take.

Two independent front-panel JFET instrument inputs, so guitar and bass can track together, or a stereo keyboard rig. Modelled on the input stage of a classic valve amp, they give amp sims the rich, responsive signal they need.

32-bit conversion at up to 192 kHz with 128 dB of dynamic range: a lower noise floor, more headroom and monitoring you can trust when mixing.

Professional monitoring. Dual monitor outputs to check your mix on two pairs of speakers, two independent headphone amplifiers, dedicated hardware buttons for Mute, Dim, speaker switching and Talkback, an assignable function button (Mono, Reference Level or M/S mode) and dedicated input and output metering.

iD Control. Your whole session in one window: input gain, Analogue Tone Suite, DSP FX, routing and monitoring, with total recall, four artist headphone mixes, talkback using your computer's mic, loop-back for streaming and podcasting and a standalone mode that keeps your settings without a computer. Compatible with macOS and Windows.

Metal chassis, stepped encoder and back-lit meters and switches.
