This document provides a comprehensive reference for the parameters available across various audio generation models in the Scenario API. Each model has a unique modelId and a set of specific parameters that can be used to control the audio generation process. Understanding these parameters is crucial for effectively utilizing the API to achieve desired audio outputs.

Below, you will find detailed information for each audio model, including its modelId, the types of parameters it accepts, allowed values, default settings, and a clear description of each parameter's function.
