Architecture Overview

System Architecture

AudioBloomAI follows a modular architecture designed for performance, extensibility, and maintainability. The application is built on Swift 6 and targets macOS 15+.

Core Components

1. AudioBloomCore

The central module managing application state and coordination.

• Key Components:
  • AudioBridge: Core audio processing bridge with modular architecture
    • PerformanceTracker: Audio processing performance monitoring
    • FormatConverter: Audio format conversion and normalization
    • AudioBridgeNotifications: Notification system for state changes
  • Types: Shared type definitions with Sendable conformance
  • AudioDataPublisher: Real-time data flow management
  • VisualTheme: Customizable visual appearance system

2. AudioProcessor

Handles all audio processing operations using Metal acceleration.

• Key Components:
  • Audio Processing Pipeline
  • Feature Extraction System
  • Buffer Management
  • Error Recovery System

3. Visualizer

Manages real-time visualization using Metal.

• Key Components:
  • Metal Shader Infrastructure
  • Visualization Renderer
  • Effect Controller
  • State Management

Technical Specifications

Development Architecture

Module Independence

Each module is designed to be independently testable and maintainable:

• Separate Swift packages
• Clear public APIs
• Minimal cross-module dependencies
• Comprehensive unit tests
• Component-level separation
• Clean import hierarchies

Extension Points

The architecture supports future extensions through:

• Plugin system (planned)
• Custom effect support
• Themeable interface
• Configurable processing pipeline

Security Considerations

• Secure audio data handling
• Resource access management
• Error handling and recovery
• State persistence security

Performance Optimization

• Efficient memory management
• Optimized render pipeline
• Smart resource allocation
• Modular component architecture
• Properly separated concerns
• Accelerate framework utilization
• Thread safety with locking mechanisms

Future Considerations

• Plugin architecture
• Additional visualization modes
• Enhanced audio processing features
• Cross-platform potential
