Generate Full-Length Song with Latent Diffusion

The "Generate Full-Length Song with Latent Diffusion" action is designed to create complete songs that resonate with your creative vision. By leveraging state-of-the-art latent diffusion techniques, this action streamlines the music creation process, allowing you to focus on the artistic aspects rather than the technical complexities.

Input Requirements:

  • Lyric: A string containing the lyrics of the song, formatted with timestamps (e.g., [00:10.00]Moonlight spills through broken blinds...).
  • Audio Length: An integer specifying the length of the generated song in seconds (currently fixed at 95 seconds).
  • Reference Prompt: A text prompt that serves as a style reference for the song.
  • Reference Audio Path: A URI to an audio file that is used as a reference for tone and style (must be longer than 10 seconds).

Expected Output: The output is a URL linking to the generated audio file of the song, which can be played or downloaded for further use.

Use Cases for this specific action:

  • Game Development: Create immersive soundtracks that adapt to gameplay or enhance narrative elements.
  • Content Creation: Generate unique background music for videos, podcasts, or live streams, providing a fresh auditory experience for your audience.
  • Personal Projects: Craft custom songs for events, presentations, or personal enjoyment without needing extensive music production skills.
