NormalizedAmplitudeToMask

Works as a bridge to the AudioScheduler -nodes: https://github.com/a1lazydog/ComfyUI-AudioScheduler Creates masks based on the normalized amplitude.

Example

JSON Example

{
  "class_type": "NormalizedAmplitudeToMask",
  "inputs": {
    "normalized_amp": [
      "node_id",
      0
    ],
    "width": 512,
    "height": 512,
    "frame_offset": 0,
    "location_x": 256,
    "location_y": 256,
    "size": 128,
    "shape": "none",
    "color": "amplitude"
  }
}

This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

Outputs

Index	Name	Type	Is List	Connection Reference
0	MASK	MASK	No	["{node_id}", 0]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this NormalizedAmplitudeToMask node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• MASK (MASK): ["5", 0]
