Reverse Reverb creates a reverb swell that builds up into a sound, rather than trailing away after it. It’s a classic production technique for transitions, vocal risers, and atmospheric builds.

​
Create a reverse reverb swell

1

Select audio clips

Select one or more audio clips. With no clip selected, every audio clip on the selected tracks is used; muted clips are left out.
2

Open the Command Palette and search

Open the Command Palette (⌘K) and search for “Reverse Reverb”.
3

Pick the reverb

Choose what the swell is rendered through — see below.
Gridshift places each swell on a new track above the clip’s track — one track per source track, however many clips you picked. Every swell peaks exactly on its clip’s first hit, so it rises straight into the sound, then fades out over the next 0.2 s so its wet rest blends into the clip. One undo removes them all, and the original clips stay unchanged. When clips sit close together, a swell starts where the one before it ends, so every swell still peaks on its own hit. A clip with no room before it, or a silent one, gets no swell, and Gridshift says how many clips were skipped. While it renders, a progress sheet counts the clips (“Clip 3 of 8”). Cancel stops it at any time, and nothing is added then. The swell follows what you hear: a trimmed clip or a single slice swells into its own hit, not into the start of the sample, and a warped or pitched clip is rendered as it sounds.

Pick the reverb

The built-in reverb gives a two-second rise. Through a plugin, the swell is as long as the reverb’s tail, up to ten seconds per effect: a long hall gives a long rise, a short room a short one. Effects that are bypassed on the return track are skipped, and a return track without an active effect can’t be picked. A plugin that isn’t installed on this Mac is marked (not installed) in the list, and if an effect can’t be loaded Gridshift says so instead of rendering without it. An effect set to 0 % wet adds no reverb, so Gridshift names it and renders nothing.
Rack presets aren’t offered — their parallel chains can’t be rendered as a single swell.
