📂 Dataset Structure

Each instance folder is named Blast_{X}_{Y}_{Z} — the blast coordinates in metres (m). Example: Blast_400.0_0.0_30.0 → blast at (400.0 m, 0.0 m, 30.0 m)

Folder / File	Audio	Visual	FPS
Drone Camera/	✅ WAV	✅ PNG	30
Main Camera/	✅ WAV	✅ PNG	60
Stereo Left Camera/	❌	✅ PNG	60
Stereo Right Camera/	❌	✅ PNG	60

📍 scene_info.md contains the position and orientation of each camera in the scene, along with blast instance locations.

All visual frames are lossless PNG at 1920×1080. Audio is mono WAV with speed-of-sound delay modelled per camera distance.
