  1. After submission, a task_id will be returned. If you provided a callback_url, when the task status becomes finished or failed, a POST request will be sent to the callback_url.
  2. Regardless of whether callback_url is provided, you can retrieve the response result through the unified Query Music Detail endpoint.

​
Usage Guide

  • This endpoint replaces a specific time range of an existing music track with new content
  • Useful for editing verses, choruses, or any specific part of a generated track
  • The replacement content is generated based on your prompt and style tags

​
Parameter Details

  • task_id (required): The original task ID from a completed music generation
  • audio_id (required): The specific audio track identifier from the callback data
  • prompt (required): Description of the replacement content (lyrics or musical description)
  • tags (required): Style tags for the replacement section
  • title (required): Title for the resulting track
  • infill_start_s (required): Start time in seconds (minimum 0, up to 2 decimals)
  • infill_end_s (required): End time in seconds (must be greater than start time)

​
Developer Notes

  • Ensure infill_end_s is always greater than infill_start_s
  • The time range should be within the duration of the original track
  • Use full_lyrics when you want to maintain lyrical consistency across the entire track

​
Optional parameters

  • negative_tags (string): Styles to exclude from the replacement section
  • full_lyrics (string): Complete lyrics for the entire track after modification
  • callback_url (string): Webhook URL for receiving completion notifications
