# Audio Granulator Apply granular synthesis to the audio > Canonical page: https://elysiatools.com/en/tools/audio-granulator - **Category:** Media - **Keywords:** audio, granular, synthesis, grains, texture, cloud, ambient, glitch, experimental ## Overview 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. ## Inputs - **Audio File** (file): Select an audio file - **Grain Size (1-500 ms)** (range): Duration of each audio grain. Smaller values = more fragmented texture. - **Grain Density (1-100 grains/sec)** (range): How many grains per second. Higher values = denser, more continuous sound. - **Time Spray (0-100 ms)** (range): Random timing variation between grains. Higher values = more scattered, unpredictable texture. - **Pitch Shift (0.25-4.0)** (range): Pitch modification of grains. Can create harmonic or dissonant clusters. - **Randomness (0-1.0)** (range): Overall randomization of grain parameters. Higher values = more chaotic, evolving texture. - **Grain Overlap (0-1.0)** (range): Amount of overlap between grains. Higher values = smoother, more blended texture. - **Wet/Dry Mix (0-1.0)** (range): Balance between dry (original) and wet (granular) signal. - **Output Format** (select) ## When to use - When transforming a standard audio clip into textured, atmospheric soundscapes for ambient music or film scores. - For creating glitchy, fragmented audio effects in electronic music production or sound design projects. - To experiment with granular synthesis techniques for innovative sound manipulation in avant-garde compositions. ## How it works - Upload an audio file in supported formats such as MP3, WAV, or FLAC. - Adjust parameters like grain size, density, spray, pitch, and randomness to shape the audio texture. - Set the wet/dry mix and output format, then process the audio to generate the granular synthesis result. ## Use cases - Creating ambient background layers for videos, games, or meditation apps. - Designing unique glitch effects or textured soundscapes for film, TV, or interactive media. - Experimenting with audio manipulation for experimental music or sound art installations. ## Frequently asked questions ### What audio file formats are supported? The tool supports MP3, AAC, M4A, OGG, Opus, FLAC, and WAV formats. ### How does grain size affect the output? Smaller grain sizes (e.g., 1-50 ms) create more fragmented, glitchy textures, while larger sizes (e.g., 100-500 ms) produce smoother, continuous sounds. ### Can I process live audio input? No, this tool only processes pre-recorded audio files; it does not support real-time audio input. ### What is the purpose of the 'spray' parameter? Spray adds random timing variation between grains, making the texture more scattered and unpredictable for creative effects. ### How do I balance the original and processed audio? Use the wet/dry mix slider to control the blend between the dry (original) and wet (granular) signals, from 0 (fully dry) to 1 (fully wet). ## Related tools - [Audio Add Chapters](https://elysiatools.com/en/tools/audio-add-chapters): Add chapters to an audio file from a label/chapters file - [Audio Caption Timing Shifter](https://elysiatools.com/en/tools/audio-caption-timing-shifter): Shift SRT or WebVTT captions to a likely speech onset or by a manual offset. - [Audio Fade In](https://elysiatools.com/en/tools/audio-fade-in): Apply a fade-in effect to the beginning of the audio - [Audio Fade Out](https://elysiatools.com/en/tools/audio-fade-out): Apply a fade-out effect to the end of the audio - [Sidechain Pump Generator](https://elysiatools.com/en/tools/audio-sidechain-pump-generator): Apply EDM-style tempo-synced pumping ducking to any audio without a kick-drum sidechain file — volume-envelope automation in the style of LFO Tool / Kickstart. - [Audio Vinyl Crackle](https://elysiatools.com/en/tools/audio-vinyl-crackle): Add vinyl crackle noise to an audio file - [Audio Script Timing Estimator](https://elysiatools.com/en/tools/audio-script-timing-estimator): Estimate how long a script will take to read aloud, with optional calibration from a recorded sample. - [Audio to Text Transcriber (AI)](https://elysiatools.com/en/tools/audio-to-text-transcriber): Transcribe speech from audio (wav/mp3/m4a/flac/ogg/webm/aac) to text, SRT, VTT or JSON using the grok-stt AI model.
