Developer Fred Anton Corvest has released FAC Gravity, an AUv3 audio plug-in designed to manipulate stereo image width and depth. The software is now available for devices running iOS, iPadOS, macOS, and visionOS.
Why it matters
This release expands the utility of the AUv3 format by bringing specialized stereo processing to the Apple ecosystem. It allows producers to perform both channel-specific adjustments and synthetic stereo imaging on mobile and desktop platforms.
The FAC Gravity plug-in is priced at $8.49 and requires iOS/iPadOS 17, macOS 14, or visionOS 1. It provides independent control of channel ratios in Stereo mode and generates stereo images from mono sources using quadrature processing.

Fred Anton Corvest
An independent software developer focused on the creation of specialized AUv3 audio plug-ins for the Apple ecosystem.
The details
FAC Gravity functions as an AUv3 plug-in, a modular standard for Apple audio software that allows effects to run within different host applications. In Stereo mode, the plug-in shifts left and right audio channels independently based on a user-defined ratio parameter. When switched to Mono mode, it employs quadrature processing—a technique that uses phase-shifted signals to create a sense of width—to synthesize a stereo field from a single input signal.

The Tech Race
This release aligns with the broader push to unify audio production workflows across the Apple ecosystem through the AUv3 architecture. It follows the industry trend of bringing desktop-grade signal processing tools to mobile and spatial computing platforms.
Producers and sound designers can now integrate this plug-in into any AUv3-compatible host on iPad, iPhone, Mac, or Apple Vision Pro. The software serves as a low-cost utility for spatializing audio mixes across the Apple hardware ecosystem.
The takeaway
The arrival of FAC Gravity highlights the increasing capability of the AUv3 format to handle complex stereo processing tasks. Users should monitor future updates from the developer to see if the plug-in receives support for multi-channel spatial audio standards beyond its current stereo capabilities.
