- Audio processing timeouts and intervals
- CGO sleep durations
- Batch processing parameters
- Event formatting and timeouts
- Process monitor calculations
- Extract monitoring constants and configuration into centralized locations
- Implement dynamic clock ticks detection for more accurate CPU metrics
- Add warmup samples and bounds checking for CPU percentage calculation
- Replace hardcoded values with constants for better maintainability
- Move audio server logic to dedicated package and simplify main.go
- Optimize buffer pool implementation and remove redundant logging
- Improve process monitoring with synchronized metrics updates
- Enhance microphone contention manager with simplified logic
- Replace mutex with atomic operations for metrics tracking
- Add new /system/memory endpoint to expose total system memory
- Implement process metrics collection for audio and microphone processes
- Update UI to display real-time process metrics with charts
- Replace environment variable check with CLI flag for audio input server
- Improve audio metrics broadcasting with 1-second intervals
- Add memory usage capping for CPU percentage metrics
