Audient iD4+ Desktop 20-In / 24-Out Audio Interface with 4 x 75dB Mic Preamps

For the engineer running serious sessions. The iD4+ (formerly the iD44) is a 20-in / 24-out desktop audio interface built around two features 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. Paired with Balanced Hardware Inserts, 16 channels of ADAT I/O, Hardware-Accelerated DSP FX and 32-bit Conversion, the iD4+ delivers a commercial studio's signal chain on the desktop, built for high-channel-count tracking and hybrid sessions.

Track Larger Sessions from the Desktop

Four microphone preamps combine with 16 channels of ADAT input and output to create a 20 input recording system suited to full band, drum, and other high channel count sessions. Two JFET instrument inputs on channels 1 and 2 provide direct instrument recording alongside the microphone inputs.

Integrate Outboard Processing Directly

Balanced hardware inserts on channels 1 and 2 provide dedicated integration for external EQs, compressors, and processors before the signal reaches the DAW. The Analogue Tone Suite adds ORBIT variable impedance, HMX harmonic saturation, LIFT high frequency boost, and GLOW combined tone shaping directly within the recording signal path.

Advanced Monitoring for Engineers and Performers

Built-in RoomTune Monitor Correction works at the hardware level with the included RM1 Reference Microphone. Dual stereo monitor outputs provide dedicated hardware monitor controls, while two independent headphone amplifiers support up to four artist mixes for recording sessions with multiple performers. Hardware accelerated EQ, compression, and reverb provide zero latency DSP monitoring.

Why choose the iD4+?

The iD4+ delivers commercial-studio signal flow in a desktop interface. Four Audient Console Mic Preamps with Smartgain, Balanced Hardware Inserts on channels 1 and 2, and 16 channels of ADAT I/O make it a 20-input tracking system capable of handling a full band or drum kit. Two Independent Headphone Amplifiers with up to four Artist Mixes let every musician in the room hear exactly what they need.

RoomTune Monitor Correction, with the included RM1 Reference Microphone, stops your room coloring what you hear, so your mixes sound right from your desk to the car and beyond.

The Analogue Tone Suite shapes the sound of your Console Mic Preamps on the way in: HMX adds warmth through a discrete MOSFET circuit, LIFT adds sheen, GLOW combines the two for a mix-ready take, and ORBIT changes the character of your mic with three voicings (Punch, Smooth and Vintage). All delivered over a single USB-C cable via bus power.
