FAC Chorus brings depth and movement to your sounds with an authentic, lush, and organic character. Built with true analog-style bucket brigade circuitry, this plugin is a modern reissue of some of the most iconic hardware units, faithfully capturing their distinctive tone.

The effect ranges from subtle doubling to rich, swirling modulation, covering different uses as a Chorus, Flanger, or Vibrato. The expanded modulation controls, multiple characters, and LFO waveforms allow precise shaping of your sound, giving you complete creative flexibility. In addition, the feedback control adds rich, flanger-like textures for dynamic sonic effects.

Under the hood, the plugin uses two individual delay line paths. Each path’s behavior is determined by the character parameter: Thick and BBD provide warm, classic BBD-style tones, while Clean delivers a more transparent tone with greater modulation.

This chorus has become a favorite in the iOS music community, combining vintage inspiration with modern control to deliver professional-quality sound in any production.

This is an AUv3 Effect and requires a compatible host to work

### 5/5 — Slick

*2026-01-02*

This is such a slick sounding chorus and sure to find a home in many a plugin arsenal - as usual with FAC plugins you can’t go wrong

### 1/5 — By renaming this app, you broke hundreds of my projects.

*2026-01-02*

I’ve had to replace FAC Chorus as my go-to chorus plugin due to your ill-advised decision to rename the desktop plugin “FAC Chorus OLD” (whether that was a temporary or permanent decision). That was not the way to do this.

### 5/5 — Love it

*2024-11-08*

Amazing in everything. Favorite chorus

### 5/5 — Great

*2024-09-13*

For the money, OMG!!

### 5/5 — Warm, weit und awwww

*2023-11-04*

Jedes einzelne absolut empfehlenswert. Was Fred A-C mit den Plugins auf iPad (und Mac Desktop) da seit Jahren abliefert ist wirklich Oberklasse! Einzige Makel ist für mich, dass es keine VST Version auf Mac Desktop oder auch Portierung zu Windows gibt 🥲
Hoffentlich kommt es irgendwann…

### 5/5 — I thought I liked choruses

*2023-11-03*

This chorus is incredible. It changed my perception of what a chorus can do. It goes hard at every turn. If you thought you already had a chorus and you’re set, think again. This one will INSPIRE you.

### 5/5 — 5 Star App - 2022 UPDATE

*2022-08-06*

Nothing new to say that I haven’t said before:

Like all of Frederic’s apps! BUY THEM ALL!

### 5/5 — Good as it gets

*2022-07-19*

Great sounding chorus. Lush and versatile.

### 5/5 — My favorite chorus

*2022-06-09*

In all honesty I am no expert when it comes to modulation effects, and so far I only used the ones that came bundled with my daws. All I can say is:

To me this one just sounds EPIC with little ado: I play a single oscillator saw wave through FAC Chorus in its initial setting and my favorite reverb and it sounds like Blade Runner.

I totally love the sound of FAC Chorus!

### 5/5 — Easy to use, looks great and sounds great

*2021-06-05*

This Chorus FX module works really well with AUM and Cubasis. It looks amazing and is very easy to use. The Thick 6A default preset is really nice. Well priced and worth adding to your collection of Audio Units apps.
