Audient iD4+ MK3 20-in/24-out USB-C Audio Interface, three-quarter view

Audient iD MK3: Four Desktop Interfaces with Room Correction Built In (2026)

The new Audient iD MK3 desktop interfaces start at $299 CAD and go up to $999 CAD. They are for people who record at home and want their mixes to sound right outside the room. Every one of the four corrects your monitors for your room, sets its own mic levels and adds analogue colour before the signal reaches your DAW.

New names for a new generation

Audient renamed the range with this generation. The iD1 replaces the iD4, the iD2 replaces the iD14, the iD2+ replaces the iD24 and the iD4+ replaces the iD44. All four connect and take their power over one USB-C cable, and they work with Mac and Windows.

RoomTune fixes what your room does to your monitors

Your room changes what you hear. Some bass notes build up, others disappear, and a mix that sounded right at your desk falls apart in the car. RoomTune measures your monitors in your room and corrects them inside the interface. It runs on the hardware, so it costs no CPU and it is on from the moment your monitors power up.

RoomTune measures with the Audient RM1 Reference Microphone. The iD2+ and iD4+ come with one in the box. For the iD1 and iD2 the RM1 is $79 CAD on its own. Audient measures every RM1 at the factory, and you enter its serial number during setup so the correction leaves the microphone's own sound out.

Smartgain sets your levels

Press Smartgain, play your loudest part, and the interface sets the mic gain for you. On the models with more than one preamp it sets every channel at once, or two channels as a matched stereo pair. The preamps are the same Class-A design Audient uses in its ASP8024-HE recording console, with 75 dB of gain. That is enough to run a quiet dynamic microphone such as the Shure SM7B without a separate booster.

Analogue Tone Suite and onboard effects

The Analogue Tone Suite adds analogue saturation to the mic preamp before the signal reaches your DAW, so a vocal or a guitar arrives with some character already on it. Each interface also has its own EQ, compression and reverb running on built-in DSP, which lets a singer hear a finished-sounding headphone mix while your computer stays free for the session.

The iD1 is the one for a solo musician: one microphone and one instrument at a time, with a hardware control for direct monitoring.

The iD2 adds a second mic preamp and a second pair of speaker outputs, so you can record a stereo source or two people and switch between two sets of monitors. Its optical input takes eight more channels from an ADAT preamp when your studio grows.

The iD2+ costs $200 more than the iD2. For that you get the RM1 in the box, two balanced hardware inserts for an outboard compressor or EQ, and an optical output beside the optical input.

The iD4+ is for recording a band. It has four mic preamps, two instrument inputs, two headphone outputs and two pairs of optical connections for 16 more channels in and out. It also includes the RM1 and the two hardware inserts.
