AB Chorus X

What it does

A cut-down iOS build of Audio Brewers’ AB Chorus, running exclusively in stereo. Rate sweeps from 0.001 Hz to 50 Hz and can sync to host tempo, depth reaches 200 percent, and feedback goes into deliberately unstable territory. Rate, depth and center are set separately per side, and a buoyancy control widens the image.

In the demo

Jade runs it in Logic Pro for iPad on acoustic guitar and a Wurlitzer, moving each control on its own so the effect is audible in isolation. She toggles stereo against mono, pushes feedback until it turns chaotic, then raises buoyancy to show it working more like a widener.

Worth knowing

There are no presets, so every sound is built by hand. The desktop version at Audio Brewers costs $49 and adds binaural, surround and Dolby Atmos handling that this iOS edition does not have, so anyone needing those formats is buying the wrong one here.
