The Audient iD4 High-Performance USB Audio Interface was designed with musicians in mind to simplify the recording process while providing the artist with one of the company's renowned Class-A console-grade microphone preamplifiers. Housed in a desktop-style chassis, it delivers the audio performance of a large-format console in a compact and elegant desktop package. The unit provides a world-class Audient console mic pre, high performance converter technology, console-style monitor control, JFET D.I., and the revolutionary ScrollControl. The iD4 is USB bus-powered and compatible with Mac OS X, Windows, and iOS.

Microphone Preamps

  • Use a class-A microphone design developed by legend David Dearden and optimized over 18 years of refinement
  • Clean, punchy and musical character
  • Flexible topology – design optimized gain range between 0 - 70 dB gain
  • Low Noise Floor: 30,000 times quieter than the signal level
  • Wide Bandwidth: Preserving your transient detail
  • Transformer-less, RF-immune input stage for detailed resolution


iD4 provides you with high-performance AD-DA converters. Quality in the analog stages of design comes from years of experience as analog console designers, and when coupled with outstanding converter technology it enables you to hear audio as it’s supposed to sound


With a touch of a button iD4’s volume encoder becomes a virtual scroll wheel, enabling you to adjust DAW hosts, plug-in parameters and even scroll through your iTunes library, just like you’re adjusting a piece of hardware. Wherever your mouse pointer hovers, the iD knob can scroll to control, and when you're not using ScrollControl, pressing iD4’s volume encoder activates DIM, enabling you to quickly reduce the playback volume

Plug and Play

iD4 has a harmonically rich JFET D.I input. Designed to replicate the input stage of a classic valve amplifier, you can plug your guitar, bass, keyboard, or drum machine straight in and start recording instantly

Monitor Pan

iD4’s Monitor Pan feature enables you to pan both the mic pre input and D.I input from left to right, making it easy for you to create a balanced headphone mix that suits you

Monitor Mix

iD4’s Monitor Mix feature lets you monitor a blend of both iD4’s inputs and your DAW playback, providing near-zero-latency monitoring while recording. Designed with creativity in mind, Monitor Mix allows you to quickly blend in your DAW playback and start recording along to your multitrack instantly, enabling you to focus on the music and lay down your track effortlessly

Dual Headphone Outputs

Featuring a dual headphone output, iD4 enables you to collaborate with your friends and other artists. Whether you’re recording a guitar and a vocal, or just listening to music together, iD4 lets you plug in two sets of headphones, making it the perfect tool for jamming with your friends and capturing creativity as it happens. The dual headphone output also has both a jack and mini jack output, so no more need to carry around a headphone adapter

Built to Last

iD4 has been designed to last, from its all-metal construction, hand-finished aluminum knobs and high-grade component selection, iD4 will stand up to countless late nights in the studio and days on the road
