Additionally, it comes with a suite of UAD plug-ins and a Digital Audio Workstation (DAW), adding significant value for users looking to enhance their recording experience.
Build Quality and Design
In terms of build quality, the Audient iD4 MKII is constructed with an all-metal desktop housing, providing both stability and durability. This design makes it ideal for users who need a reliable interface for mobile recording sessions. The device is compact, measuring 133x120x40.7 mm and weighing 740 g, which adds to its portability.
On the other hand, the Universal Audio Volt 1 is also designed for portability, making it suitable for recording on the go. It requires an external power supply and an Apple Lightning to USB Camera Adapter for mobile use, which may be a slight inconvenience for some users. However, its lightweight construction ensures that it can easily fit into a bag for transport.
Audio Quality and Performance
The Audient iD4 MKII excels in audio quality, thanks to its Class A console microphone preamp derived from Audient's high-end ASP8024 HE console. This technology enhances the sonic performance, making it suitable for professional-level recordings. Users can expect a harmonious overall package that significantly improves home recording quality.
Conversely, the Universal Audio Volt 1 offers a unique Vintage mode that replicates the sound of UA’s classic 610 preamps, which can be particularly appealing to those seeking a vintage sound profile. With its ability to capture up to 24-bit / 192 kHz quality, users can expect crystal-clear audio recordings.

Both products provide good compatibility, but the iD4 MKII has an edge in terms of connectivity convenience.
Software and Additional Features
The Audient iD4 MKII does not explicitly mention bundled software, but its hardware capabilities make it suitable for use with various DAWs. The focus here is primarily on the interface's audio performance.

This makes the Volt 1 approximately 35% cheaper than the iD4 MKII. For those on a budget or just starting their recording journey, the lower price of the Volt 1 may be a decisive factor.
However, the higher price of the iD4 MKII can be justified by its superior build quality, robust audio performance, and ease of connectivity. Users must weigh their budget against the features and performance they require in an audio interface.
Which should you buy?
