Audio Granulator

Apply granular synthesis to the audio

Deconstructs audio into tiny sonic grains and reassembles them with new timing, pitch, and texture characteristics. Creates ethereal clouds, glitch textures, and evolving soundscapes characteristic of granular synthesis. Perfect for ambient music, sound design, and experimental audio manipulation.

Grain Size (1-500 ms)

1 50 500

Duration of each audio grain. Smaller values = more fragmented texture.

Grain Density (1-100 grains/sec)

1 30 100

How many grains per second. Higher values = denser, more continuous sound.

Time Spray (0-100 ms)

0 20 100

Random timing variation between grains. Higher values = more scattered, unpredictable texture.

Pitch Shift (0.25-4.0)

0.25 1 4

Pitch modification of grains. Can create harmonic or dissonant clusters.

Randomness (0-1.0)

0 0.4 1

Overall randomization of grain parameters. Higher values = more chaotic, evolving texture.

Grain Overlap (0-1.0)

0 0.3 1

Amount of overlap between grains. Higher values = smoother, more blended texture.

Wet/Dry Mix (0-1.0)

0 0.75 1

Balance between dry (original) and wet (granular) signal.
