Detailed Description

Central helper for extraction operations - uses analyzers to find data.

ExtractionHelper uses analyzers to identify regions/features of interest, then extracts and returns the actual DATA from those regions.

Key concept: Analyzers find WHERE, extractors return WHAT.

• Analyzer: "High energy at samples 1000-1500, 3000-3500"
• Extractor: Returns the actual audio data from samples 1000-1500, 3000-3500
