Gaussian Blur - AUv3 Reverb

Gaussian Blur is a bloom reverb Audio Unit (AUv3) plugin. It splits incoming audio into overlapping grains and sends them into a plate-style reverb tail. You control how long the grains are, when they play, how much they blend together and how long they ring out. Use it to turn vocals into slow swells or smear guitar chords into ambient pads.

CONTROL WHEN THE REVERB BUILDS
The bloom curve spreads the grains out over time or bunches them around one moment. Drag the curve to move that moment earlier or later, so the reverb comes in right away or swells up seconds after the sound.
• Bloom time from 20 ms to 5 seconds
• Tempo sync, including dotted and triplet divisions

SHAPE THE GRAINS
Short grains chop the source into small pieces. Longer grains keep more of the original phrase. When they spread out and overlap, you get strange, alien spaces.
• Grain Size: 20 ms to 1 second
• Direction: blend forward and reversed grains for reverse reverb swells
• Shimmer: shift some of the grains up an octave, or up fifths and octaves
• Grain Tone: adjust brightness before the grains reach the reverb tail

LONG DECAY AND RECIRCULATION
Let a pluck ring out between notes, or stretch a chord into a pad that sits behind the next phrase. With up to 40 seconds of decay, one short sound can carry a whole passage.
Recirculate sends the signal through the grain processing again for more passes. It doesn't sound like a standard feedback knob.

MADE FOR
• Ambient and cinematic pads from any source
• Vocal throws and reverse reverb swells
• Guitar and synth textures for shoegaze and post-rock
• Sound design accents and transitions
