Transmitting surround sound by laser light

Summary

DIYP distributes digital audio signals optically by laser to several wireless speaker positions. The original video has the ID 1H4FuNAByUs. Unusual transmission paths are worthwhile when their physical limits suit the environment.

Ideas

  • Light can carry digital audio data without a radio band or galvanic connection.
  • A clear line of sight replaces cables but requires precise alignment.
