## What is Gaussian Blur?

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

REQUIREMENTS
iOS 18.6 or later and an AUv3-compatible host app.

## Frequently asked questions about Gaussian Blur

### What is Gaussian Blur?

Gaussian Blur is an Audio Unit (AUv3) plugin that creates a unique bloom reverb effect. It works by splitting incoming audio into overlapping grains and processing them through a plate-style reverb tail, allowing for extensive sound shaping.

### What kind of reverb does Gaussian Blur create?

Gaussian Blur specializes in 'bloom' reverb, which can create slow swells or smear sounds into ambient pads. It offers granular control over how the reverb builds and decays, unlike traditional reverb plugins.

### Can I sync Gaussian Blur to my project's tempo?

Yes, Gaussian Blur offers tempo sync for its grains, including dotted and triplet divisions. This allows you to precisely align the reverb's timing with your music.

### What are the grain controls in Gaussian Blur?

You can adjust Grain Size from 20 ms to 1 second, blend forward and reversed grains for reverse effects, add shimmer by shifting grains up octaves or fifths, and control the brightness of grains before they reach the reverb tail.

### How long can the reverb decay in Gaussian Blur?

Gaussian Blur allows for a decay time of up to 40 seconds. This enables even short sounds to sustain and carry through an entire musical passage, creating rich, evolving textures.

### What devices and iOS versions does Gaussian Blur support?

Gaussian Blur is compatible with iPhone and iPad devices and requires iOS 18.6 or later. It also needs an AUv3-compatible host app to function.

### How much does Gaussian Blur cost?

Gaussian Blur is a paid application priced at $3.99. There are no in-app purchases or subscriptions associated with this app.

### Does Gaussian Blur have ads?

No, Gaussian Blur is completely ad-free. As a paid application, it provides an uninterrupted user experience without any advertisements.
