  title: "Sound Event Detection Guide"
  content: |
    ## Your Task
    Mark the START and END times of each distinct sound event.
 
    ## Event Detection Rules
    - Mark sounds that are clearly audible
    - Include overlapping sounds (use multiple labels)
    - Short sounds (<100ms) may be a single point
 
    ## Segment Boundaries
    - Start: When sound becomes audible
    - End: When sound fades or stops
 
    ## Confidence Levels
    - Clear: Easily identifiable
    - Moderate: Reasonably sure
    - Faint: Background, hard to identify
 
    ## Foreground vs Background
    - Foreground: Main focus of audio
    - Background: Ambient sounds
