Quick start

Call this tool from your code in three languages.

cURL

# 1) Upload each file first → returns { filePath }
curl -X POST 'https://api.elysiatools.com/upload/audio-granulator' \
  -F 'file=@/path/to/audioFile.ext'

# 2) Call the tool with the returned filePath values
curl -X POST 'https://api.elysiatools.com/en/api/tools/audio-granulator' \
  -F 'audioFile=/path/to/file.ext' \
  -F 'grainSize=50' \
  -F 'density=30' \
  -F 'spray=20' \
  -F 'pitch=1' \
  -F 'randomness=0.4' \
  -F 'overlap=0.3' \
  -F 'mix=0.75' \
  -F 'outputFormat=mp3'

API reference

Send a POST request with your inputs as JSON. File parameters require a separate upload first.

Endpoint

HTTP

POST https://api.elysiatools.com/en/api/tools/audio-granulator

Parameters

Name	Type	Required	Description
audioFile	fileupload required	Yes	—
grainSize	range	No	Duration of each audio grain. Smaller values = more fragmented texture.
density	range	No	How many grains per second. Higher values = denser, more continuous sound.
spray	range	No	Random timing variation between grains. Higher values = more scattered, unpredictable texture.
pitch	range

MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.

Server configuration

Add this block to your MCP client configuration:

mcp.json

{
  "mcpServers": {
    "elysiatools-audio-granulator": {
      "name": "audio-granulator",
      "description": "Apply granular synthesis to the audio",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=audio-granulator",
      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "audio-granulator",
    "arguments": {
  "audioFile": "https://example.com/file.ext",
  "grainSize": 50,
  "density": 30,
  "spray": 20,
  "pitch": 1,
  "randomness": 0.4,
  "overlap": 0.3,
  "mix": 0.75,
  "outputFormat": "mp3"
}
  }
}

Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
