[Freeswitch-users] Getting real-time amplitude of a channel

Hi all, I am interested in providing a visualization of a channel in a conference. I am able to process the start talking and stop talking events from the conference, but I'm wondering, has anyone done anything that can get the real-time amplitude of a channel? I didn't see any built-in API commands to do this, but wondering if there's any modules or something else that I'm overlooking? Or maybe now is the time for me to dig into the API documentation? Just curious if anyone has done something like this before, and if so, if you could guide me in the right direction. Thanks! Matt
