Generate Audio with MAGNeT

The "Generate Audio with MAGNeT" action allows you to create music guided by textual prompts. Using a Single Non-Autoregressive Transformer, this action excels at producing diverse audio outputs based on the parameters you set.

Input Requirements

To utilize this action, you need to provide the following parameters:

  • prompt: A textual description of the music you want to generate (e.g., "80s electronic track with melodic synthesizers").
  • model: Choose from various predefined models, each designed for different audio lengths and qualities.
  • topP: A number between 0 and 1 that adjusts the diversity of the output.
  • variations: Specify how many different audio outputs you want (between 1 and 4).
  • temperature: Controls the randomness of the output, with higher values resulting in more varied music.
  • maxConfiguration and minConfiguration: These parameters help you set the constraints for the generation process.
  • spanScoringMethod: Choose the method for scoring spans in the audio output.
  • decodingStepsStage1 to decodingStepsStage4: Define the number of decoding steps at each stage of the generation process.

Expected Output

The output will consist of URLs pointing to the generated audio files. Each output will be a unique piece of music based on your specified prompt and parameters.

Use Cases for this specific action

  • Content Creation: Quickly generate background music for videos, podcasts, or live streams to enhance viewer engagement.
