Wiro - Generate Sound Effects for Video

Generates sound effects for video using AI

Overview

This node, "Wiro - Generate Sound Effects for Video," uses an AI-powered service to generate sound effects tailored to a given video. By providing a video URL and descriptive prompts, users can create customized audio enhancements that match the video's style or mood. This is particularly useful for video editors, content creators, or marketers who want to enrich their videos with unique soundscapes without manually sourcing or designing audio.

Practical examples:

  • Adding cinematic sound effects to a short film clip.
  • Creating ambient background sounds for a travel vlog.
  • Generating thematic audio cues for promotional videos based on textual descriptions.

Properties

Name Meaning
Input Video URL URL of the video to which the sound effect will be applied.
Prompt Text prompt describing the desired style or characteristics of the sound effect.
Negative Prompt Text prompt specifying undesired qualities to avoid in the generated sound (e.g., "bad, blurry").
Steps Number of inference steps controlling the detail and quality of the generation (1 to 100).
Duration Length in seconds of the generated video segment with sound effects (1 to 30 seconds).
Strength Intensity or strength of the visual effect applied (scale from 1 to 10).
Seed Random seed value for reproducibility of results.

Output

The node outputs a JSON object containing:

  • taskid: The unique identifier of the processing task.
  • url: The URL where the processed video with generated sound effects can be accessed (present if the task completes successfully).
  • status: Status of the task, which can be "completed" or "failed".

No binary data output is produced by this node; it provides URLs to access the resulting media.

Dependencies

  • Requires an API key credential for authentication with the external Wiro AI service.
  • Makes HTTP POST requests to the Wiro API endpoint at https://api.wiro.ai/v1/Run/wiro/mmaudio.
  • Uses a polling mechanism to wait until the asynchronous task completes, relying on socket access tokens provided by the API.
  • Requires proper configuration of the API key and secret within n8n credentials.

Troubleshooting

  • Common issues:

    • Missing or invalid API credentials will cause authentication failures.
    • Providing an invalid or inaccessible video URL may result in task failure.
    • Network issues can interrupt communication with the Wiro API.
    • Incorrect parameter values (e.g., out-of-range steps or duration) might cause errors or unexpected results.

  • Error messages:

    • If the API response lacks a valid task ID or socket token, the node throws an error indicating an invalid response from the Wiro API.
    • Task status codes -1, -2, -3, or -4 indicate failure states; users should verify input parameters and API availability.

  • Resolution tips:

    • Ensure all required properties are correctly set and within allowed ranges.
    • Verify network connectivity and API credential validity.
    • Check the accessibility of the input video URL.
    • Review the negative prompt to avoid overly restrictive filters that might block generation.
