Upload & Cover Audio
AI-generatedSummary
Upload an audio file from a publicly accessible URL and generate a cover audio overlay optionally styled by a music description.
Inputs
- Upload URL (required) — Publicly accessible URL of the audio file to upload.
- Prompt — Text description of the music or lyrics to generate for the cover audio.
- Style — Music style description to influence the cover audio style (e.g. "upbeat pop", "jazz ballad").
- Reply URL — Optional webhook URL to be called when the upload and cover task completes.
- Reply Ref — Optional custom reference string passed back in the webhook callback.
- Wait for Completion — Boolean to control if the node waits and polls for the task completion before returning (defaults to true).
Output shape
a list of task result objects from the Kie.ai API
If 'Wait for Completion' is true, the node polls the dedicated endpoint until the cover audio generation task completes or times out after 5 minutes; otherwise, it returns the initial task creation response immediately. The output includes processed task data with URLs for the resulting audio cover overlay, if successful.
Examples
Example 1: Upload a raw audio file URL and add a stylistic cover audio overlay, waiting for processing to finish before proceeding.
Set 'Upload URL' to the audio file URL, optionally provide a 'Prompt' and 'Style' describing the desired cover audio, and enable 'Wait for Completion' to get the final processed result.
