Overview

This node integrates with the Nemotron API by NVIDIA via the Wiro platform to process audio files. It accepts an audio file URL in supported formats (.wav, .m4a, .mp3, .ogg, .opus, webm), sends it to the Nemotron API for processing, and polls the task status until completion. It is useful for scenarios where automated audio processing or transcription is needed, such as converting speech to text or analyzing audio content.

Use Case Examples

1. A user provides a URL to an audio recording and receives a processed output URL after the Nemotron API completes the task.
2. Automated workflows that require audio analysis or transcription can use this node to handle audio input and retrieve results asynchronously.

Properties

Output

JSON

• taskid - The unique identifier of the processing task assigned by the Nemotron API.
• url - The URL to the processed audio result, available after task completion.
• status - The status of the processing task, indicating whether it is 'completed' or 'failed'.

Dependencies

• Requires Wiro API credentials (API key and secret) for authentication.

Troubleshooting

• If the node throws an error stating that the Wiro API did not return a valid task ID or socket access token, verify that the input audio URL is correct and that the API credentials are valid.
• Task status codes '-1', '-2', '-3', or '-4' indicate failure; check the audio file format and network connectivity.
• Ensure the audio URL is accessible and the file format is supported to avoid processing errors.
