Refactor api_v2.py and api_v3.py to update sampling parameters and weight paths for better clarity and support for v3/v4 vocoders. Introduce new methods in PrepareCoordinator for handling empty text features and improve profiling capabilities. Additionally, update unified engine components to streamline audio processing and state management, enhancing overall performance and maintainability of the TTS system.
Introduce new modules including EngineApiDelegates, EngineBridgeDelegates, EngineRegistryBridgeFacade, EngineRuntimeBridgeFacade, EngineStageBridgeFacade, and EngineStageOrchestrator. These additions provide a structured approach to managing TTS requests, engine states, and orchestration, significantly improving the architecture and maintainability of the TTS system. The new components support asynchronous operations and enhance overall performance through better request handling and processing capabilities.
