FAC Chorus is a versatile chorus effect emulation designed to simulate the characteristics of classic chorus modules while offering the flexibility to customize the parameters of the main components in the signal path. This iPhone app, developed by Frederic Corvest, falls under the Multimedia category, specifically Music & Radio.

With its unique and sober interface, FAC Chorus provides a great user experience. The responsive knobs follow a specific curve based on the parameter type, making it easy to adjust and fine-tune the effect to your liking.

The effect itself is built upon two individual delay line paths that are controlled by common parameters. The chorus type parameter defines the behavior of each delay signal path. The "Thick" type emulates the warm characteristics and behavior of the BBD, while the "Clean" type produces a cleaner sound with a larger modulation.

FAC Chorus is suitable for any situation that requires chorus effects, and it can range from subtle enhancements to drastic changes. The factory presets offer an overview of the sonic possibilities that can be achieved with this versatile chorus effect emulation.
