Detailed Description

Span-based energy analysis for digital signals in Maya Flux.

Defines the EnergyAnalyzer using the new UniversalAnalyzer framework with zero-copy span processing and automatic structure handling via OperationHelper. This analyzer extracts energy-related features from digital signals with multiple computation methods and flexible output configurations.

Key Features:

• Zero-copy processing: Uses spans for maximum efficiency
• Template-flexible I/O: Instance defines input/output types at construction
• Multiple energy methods: RMS, peak, spectral, zero-crossing, harmonic, power, dynamic range
• Parallel processing: Utilizes std::execution for performance
• Energy classification: Maps values to qualitative levels (silent, quiet, etc.)
• Window-based analysis: Configurable window size and hop size
• Automatic data handling: OperationHelper manages all extraction/conversion
