DDD Architecture for Audio.Service

This diagram illustrates the Domain-Driven Design (DDD) architecture for the Audio.Service solution, showing the relationships between the layers and their key components.

Layer Details

• API Layer: Controllers and endpoints for handling HTTP requests.
• Application Layer: Use cases and application services that orchestrate domain logic.
• Domain Layer: Core business entities, value objects, and domain services.
• Infrastructure Layer: Repositories, external integrations, and persistence mechanisms.

Key Relationships

The arrows represent dependencies: higher layers depend on lower layers, with Infrastructure providing implementations for Domain interfaces.
