FAC Chorus is a professional AUv3 chorus plugin designed to add lush depth, width, and movement to modern music productions. Available on the Apple App Store, it delivers premium analog modulation effects for producers working on iPhone, iPad, macOS, and Apple’s spatial audio platform.

Developed by Fred Anton Corvest, FAC Chorus faithfully recreates the warm, organic character of vintage hardware while offering modern flexibility. The effect ranges from subtle doubling and stereo widening to rich, swirling modulation suited for Ambient Music, Synthwave, Electronic Music, and cinematic soundscapes.

FAC Chorus integrates seamlessly with leading digital audio workstations including Logic Pro, GarageBand, Cubasis, AUM, and Audiobus. As a true AUv3 effect, it requires a compatible host but delivers studio-quality processing once loaded.

Under the hood, FAC Chorus offers expanded modulation depth with multiple characters and waveforms, allowing precise shaping of time-based effects. Whether used for Sound Design, Mixing, or Mastering, it provides creative flexibility without overwhelming the user.

Highly regarded within the iOS Music Community, FAC Chorus is frequently used to enhance Synthesizer, Guitar, Bass Guitar, vocals, and pads. It stands out as a go-to professional modulation plugin for producers seeking authentic analog tone with modern control.
