Question/Tutorial : how to effectively use audio_capture_node in ROS2

[antbono]

Hello everyone! I am quite new to ros2 and I am trying to understand how to effectively use audio_capture_node. I think that a common case is recording when some conditions are true and, possibly, for a variable period of time. How can you do this? Do you launch this node from another one? If yes, how? I hope the question is clear.

Thanks!
