file· File resultOpen tool

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-ring-modulator' \
  -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-ring-modulator' \
  -F 'audioFile=/path/to/file.ext' \
  -F 'carrierFreq=440' \
  -F 'modulationDepth=1' \
  -F 'waveform=sine' \
  -F 'mix=0.5' \
  -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-ring-modulator

Parameters

Name	Type	Required	Description
audioFile	fileupload required	Yes	—
carrierFreq	number	No	Frequency of the carrier oscillator. Lower values create slow pulsing, higher values create metallic tones.
modulationDepth	range	No	Intensity of the modulation. Higher values create more dramatic metallic effects.
waveform	select	No	Shape of the carrier oscillator waveform. Each creates different metallic character.

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-ring-modulator": {
      "name": "audio-ring-modulator",
      "description": "Apply ring modulation for a metallic, bell-like sound",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=audio-ring-modulator",
      "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-ring-modulator",
    "arguments": {
  "audioFile": "https://example.com/file.ext",
  "carrierFreq": 440,
  "modulationDepth": 1,
  "waveform": "sine",
  "mix": 0.5,
  "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).
