Overview
This node integrates with the AdBlast API to update the sound associated with a specific visual element within a scene of a project. It allows users to either generate new sound based on a textual prompt or provide a remote sound URL to be downloaded and stored for that visual. This is particularly useful in multimedia projects where dynamic audio needs to be linked or updated for visuals programmatically, such as in interactive presentations, video editing workflows, or game development pipelines.
Practical examples:
- Automatically updating background sounds for scenes in a video project based on descriptive prompts.
- Replacing or adding sound effects to specific visuals in an animation by providing URLs to audio files.
- Dynamically generating soundscapes for scenes in virtual environments using AI-generated audio from prompts.
Properties
| Name | Meaning |
|---|---|
| Authentication Method | Choose between using saved API credentials or entering an API key dynamically via expressions. |
| AdBlast Base URL | The base URL for the AdBlast API (required if using dynamic API key authentication). |
| API Key | The API key for authenticating requests to AdBlast (used if dynamic authentication method is selected). |
| Project Id | The unique identifier of the project containing the scene and visual to update. |
| Scene Id | The identifier of the scene within the project where the visual is located. |
| Visual Id | The identifier of the visual element whose sound will be updated. |
| Prompt | A text prompt used to generate new sound for the visual. |
| Sound Url | A remote URL pointing to an audio file to download and associate with the visual instead of generating it. |
Output
The node outputs JSON data representing the result of the update operation performed on the visual's sound. This typically includes confirmation details about the updated sound resource, such as identifiers, status, or metadata returned by the AdBlast API.
If binary data is involved (e.g., downloaded audio), it would be handled internally but is not explicitly exposed in the output JSON.
Dependencies
- Requires access to the AdBlast API endpoint, which can be configured via a base URL.
- Requires an API key credential for authentication, either stored securely in n8n or provided dynamically at runtime.
- Network connectivity to the specified AdBlast API base URL.
- No additional external dependencies are indicated beyond the API interaction.
Troubleshooting
- Authentication errors: Ensure the API key is valid and correctly provided according to the chosen authentication method. If using dynamic keys, verify the expression resolves properly.
- Invalid IDs: Confirm that the Project Id, Scene Id, and Visual Id correspond to existing resources in the AdBlast system.
- Network issues: Check connectivity to the AdBlast API base URL and ensure no firewall or proxy blocks the requests.
- Prompt or Sound URL issues: If the prompt is invalid or the sound URL is unreachable or points to an unsupported format, the update may fail. Validate inputs before execution.
- API response errors: Review error messages returned by the API for clues; common issues include rate limits, malformed requests, or permission problems.
