<!--
  An example world to demo how logical audio sources and microphones interact.

  2 sources are created, which are attached to a red and blue box.
  2 microphones are created, which are attached to a green and yellow box.

  The boxes can be moved to mimic sensors attached to a moving robot.

  To start and stop the audio sources, use the <PREFIX>/source_<id>/play and
  <PREFIX>/source_<id>/stop service calls.

  To play the source attached to the blue box, run the following command:
    ign service -s /model/blue_box/sensor/source_1/play
      --reqtype ignition.msgs.Empty --reptype ignition.msgs.Boolean
      --timeout 1000 --req 'unused: false'

  To stop the source attached to the blue box, run the following command:
    ign service -s /model/blue_box/sensor/source_1/stop
      --reqtype ignition.msgs.Empty --reptype ignition.msgs.Boolean
      --timeout 1000 --req 'unused: false'

  To observe microphone detections, use the <PREFIX>/mic_<id>/detection topic.

  The following command will display detections heard by the microphone attached
  to the green box:
    ign topic -e -t /model/green_box/sensor/mic_1/detection
