Gearank High Notes

NB: This has been superseded by the Audient iD4 MKII.

The ID4 is an audio interface that features Audient's class A mic preamp and JFET circuit packed in a compact unit. It provides an all-in-one solution for recording vocals and instruments, two things that most home studios need.

And judging by how the Audient ID4 continues to rake in high scoring reviews, they may have found the best balance of features, price, and cost in the ID4.

Besides its two distinct input circuits, Audient equipped the ID4 with essential output options that include 2 x 1/4" outs for stereo monitoring, and two headphone outputs.

Other practical features include monitor mixing (input and processed sound), monitor mute, and monitor panning.

Being class-compliant, this audio interface works with popular operating systems, including Apple's OSX and iOS, and Windows.

Note that this unit is USB bus powered, so it will get the power from your desktop or laptop computer. It can also work with Apple iPad and iPhone, but it requires a powered USB hub to work.

The Audient ID4 continues to get high scores for its sound and build quality, from users of different backgrounds including singers, instrumentalists, voice-over artists, home studio owners, and more. Sound quality is its biggest strength, while its reliability is a close second. It also helps that the ID4 is easy on the eyes and compact, making it an inspiring tool to use in the studio or while on the move.


There are a few users who dislike the transparency of ID4's mic preamp. There are also a few who gave lower scores for lack of MIDI in/out.


If you're looking to maximize your $200 and want no less than what the market rates as the best, then get the Audient ID4.
