Implementing a File Structure that Embraces Clean Architecture (Inspired by Uncle Bob)

Issue Description:
To ensure the long-term maintainability, scalability, and testability of our codebase, it is crucial to establish a well-defined and organized file structure that follows the principles of Clean Architecture. This GitHub issue proposes the adoption of a file structure that embraces the principles outlined by [Uncle Bob (Robert C. Martin)](https://blog.cleancoder.com/uncle-bob/2012/08/13/the-clean-architecture.html) to promote modularity, separation of concerns, and a clear architectural boundary within our codebase.

Benefits of Clean Architecture File Structure:

1. **Modularity and Separation of Concerns**: Clean Architecture emphasizes the separation of concerns, enabling us to build loosely coupled modules with distinct responsibilities. By implementing a file structure aligned with Clean Architecture principles, we can achieve clear module boundaries, making it easier to reason about and maintain our codebase. This modularity allows us to make changes within a specific module without impacting the entire system, promoting code reusability and reducing the risk of unintended consequences.

2. **Testability**: Clean Architecture advocates for comprehensive testing, including unit tests, integration tests, and end-to-end tests. A well-structured file system that aligns with Clean Architecture facilitates the isolation of business logic from external dependencies, making it easier to write unit tests with high coverage. This improved testability ensures that our codebase remains robust, allowing us to catch potential issues early and maintain confidence in the quality of our application.

3. **Flexibility and Future-Proofing**: By adhering to the principles of Clean Architecture, we establish an architectural foundation that promotes flexibility and future-proofing. A well-structured file system with clearly defined boundaries allows us to introduce new features, adapt to evolving requirements, and incorporate technological advancements more effectively. This flexibility enables us to iterate and scale our application with ease, ensuring its longevity and adaptability in a rapidly changing development landscape.

4. **Codebase Organization and Readability**: Adopting a file structure inspired by Clean Architecture enhances the organization and readability of our codebase. By separating concerns into distinct layers, such as domain, application, and infrastructure, we create a clear structure that reflects the architectural concepts behind our application. This organization improves code discoverability, making it easier for developers to navigate and understand the codebase, leading to increased productivity and reduced onboarding time for new team members.

5. **Enforced Dependency Inversion**: Clean Architecture emphasizes the Dependency Inversion Principle, which encourages us to depend on abstractions rather than concrete implementations. By structuring our files to enforce this principle, we establish a clear separation between high-level and low-level modules, ensuring that dependencies flow in the right direction. This architectural pattern minimizes coupling and enables easier substitution of components, facilitating maintainability, extensibility, and the integration of third-party libraries or frameworks.

6. **Improved Collaboration and Onboarding**: A well-structured file system that follows Clean Architecture principles promotes collaboration and onboarding efficiency within the development team. With clearly defined boundaries, developers can work independently on different modules, reducing merge conflicts and facilitating parallel development. Furthermore, new team members can quickly grasp the overall architecture and locate the relevant files for their assigned tasks, accelerating their onboarding process.

7. **Alignment with Best Practices and Industry Standards**: Clean Architecture, pioneered by Uncle Bob, is widely regarded as a best practice for building scalable and maintainable software systems. By adopting a file structure inspired by Clean Architecture, we align ourselves with industry standards and benefit from the collective knowledge and experience of the software development community. This alignment ensures that our codebase follows established conventions and facilitates future collaboration with external contributors or open-source initiatives.

Conclusion:
Implementing a file structure that embraces Clean Architecture principles offers numerous benefits, including modularity, separation of concerns, enhanced testability, flexibility, codebase organization,

enforced dependency inversion, improved collaboration, and alignment with industry best practices. By adopting this approach, we lay a strong foundation for our codebase, enabling us to build a scalable, maintainable, and future-proof audio editing application that can evolve with changing requirements and technological advancements.
