Detect if app is really playing something or is silence

cn flag

I need to determine how much sound is really coming out from specific application as a number from terminal. (this is called silence in pavucontrol) I don't want to detect application current volume or if it's state is running.

I can see what I need in PulseAudio volume control. For example now both firefox and spotify are running but spotify is not silence.

I just want to detect the same thing in terminal if possible.

Thanks in advance.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
