Warning: This is not a stand-alone tool. The visualizer expects a ZIP file containing an audio file (MP3 or WAV), a JSON file with the identified blast-beat sections, and optionally a drum-only audio track.

Expected JSON structure:

    {
      "blast_beats": [
        {"start_time": 12.5, "end_time": 15.0},
        {"start_time": 30.0, "end_time": 32.5},
        ...
      ]
    }
