- Update .gitignore to reflect new project structure - Update config.json with refined audio streaming settings - Update package.json with all required npm dependencies and scripts - Update package-lock.json with resolved dependency tree - Update requirements.txt with finalized Python dependencies (Flask, websockets, numpy, sounddevice) - Update pytest.ini with proper Python test discovery and output formatting
Backend Core Components: - server.py: Main entry point initializing HTTP server, WebSocket server, and audio capture - src/config.py: Centralized configuration management (ports, audio format, logging) - src/connection_manager.py: Manages WebSocket client connections and broadcast state - src/audio_capture.py: Captures audio from system using sounddevice and manages buffer - src/http_server.py: Flask HTTP server for serving client HTML and static assets - src/ws_server.py: WebSocket server (websockets library) for real-time audio streaming - src/__init__.py: Package initialization Features: - Real-time audio capture and streaming via WebSockets - Automatic client connection management - Buffer-based audio streaming to prevent data loss - Configurable audio format and server ports
Frontend Components: - client.html: Main HTML UI with responsive layout, controls, and visualizer canvas - static/js/connection.js: WebSocket client managing real-time connection to backend - static/js/audio.js: Audio decoding (base64 to PCM) and Web Audio API integration - static/js/ui.js: UI controls (play/pause, status display, connection state) - static/js/visualizer.js: Real-time frequency visualization using canvas - static/js/stats.js: Performance metrics (buffer size, sample rate, latency) Features: - Real-time WebSocket connection with automatic reconnection - Audio decoding and streaming playback via Web Audio API - Live frequency spectrum visualization - Performance monitoring and statistics display - Responsive design with dark theme
Test Structure: - tests/python/: pytest-based backend unit tests - test_placeholder.py: Placeholder for audio capture and WebSocket tests - properties/__init__.py: Property-based testing support - tests/javascript/: Jest-based frontend unit tests - placeholder.test.js: Placeholder for WebSocket client and audio tests - properties/.gitkeep: Property-based testing directory - tests/__init__.py: Test package initialization Configuration: - pytest.ini configured for Python test discovery and output formatting - package.json includes Jest configuration with JSDOM test environment Purpose: - Establish testing framework for continuous validation - Prepare infrastructure for unit and property-based tests - Enable CI/CD integration for automated test execution
Files: - LICENSE: Update project licensing information - sexy audio.bat: Windows batch script for running the application Purpose: - Provide legal licensing information for the project - Enable cross-platform development with Windows support - Simplify application startup on different operating systems

Pull request overview
Note
Copilot was unable to run its full agentic suite in this review.
This PR primarily normalizes file formatting (notably line endings), refreshes the client UI/README, and improves backend streaming reliability by moving blocking audio capture off the asyncio event loop and adding basic concurrency protection for client management.
Changes:
- Offload blocking audio capture to a thread executor in the WebSocket broadcast loop.
- Add an
asyncio.Lockaround client dictionary access patterns in the connection manager (partial). - Large client UI/README refresh and widespread formatting/line-ending normalization across the repo.
