Space that gets
out of the way.Wide · Ducking Reverb

Bloom adds lush, wide reverb — then ducks it under your source while it plays and lets it bloom back in the gaps. Big space, clear vocals. And the width is automatically phase-aligned, so it never collapses in mono.

macOS · Windows · Linux — free forever. Support is optional and keeps the lights on.

Watch the tail bloom

This is the real plug-in UI, running live. The decay curve shows the tail length, and the pulsing dip is the duck — the reverb stepping back for the source, then blooming into the gaps. Turn Size, Duck and Width to feel it.

What's inside

Reverb that respects the source

Built-in duck

A sidechain from the dry envelope pushes the tail down while the source plays and lets it bloom in the gaps. Big reverb, but the vocal stays clear — no extra routing.

Wide, auto phase-aligned

The tail spreads into a lush wide image, with lows kept centred and anti-phase content tamed — so the width never hollows out or cancels on a mono system.

One knob: Size

Sweep from a tight room to a vast cathedral with a single control. Damp, Low Cut and Pre-delay shape the tone; the rest takes care of itself.

Freeze

Lock the tail into an infinite wash for pads, drones and sound design — hold a moment forever.

10 input profiles

Vocal Plate, Drum Room, Piano Hall, Synth Pad Wide and more — each sets size, tone, duck and width so you start in the right place.
