Real-time analyzing AudioData messages

asked 2021-05-03 04:49:27 -0500

Hello! I am working with a microphone-device that publishes audio as an AudioData message http://docs.ros.org/en/noetic/api/aud... .

I want to do a real-time analysis of the message, where I pinpoint a frequency range and and publish the average amplitude. Or in other words, output a numerical value of the loudness of a certain frequency range.

Has anyone done this before?

I'm running Ubuntu 18.04.
