Problem\nThe class in has no dedicated test file. It handles YAML config loading, chunk validation, and audio processing logic that should be tested independently of integration tests.\n\n## Scope\n\n1. Create with tests for .\n2. Cover these cases:\n - with valid YAML, missing file, and invalid YAML structure.\n - with valid chunks, negative start times, end <= start, end exceeds audio duration, and duplicate start times.\n - with valid inputs and a file (use ).\n - The convenience function.\n3. Do not add integration tests — keep scope to unit-level coverage.\n\n## Acceptance\n\n- ============================= test session starts ==============================
