A system for recording metadata is disclosed. The system includes an acoustic vibration sensing system. The system also includes one or more sensors operable to measure characteristic parameters. The sensors are coupled to the acoustic vibration sensing system and include one or more channels for recording metadata. The system further includes one or more optical modulators. The optical modulators modulate a signal received from the one or more sensors and direct the modulated signal to the acoustic vibration sensing system. The system further includes one or more sources of the metadata coupled to the one or more optical modulators.
