To be honest, I usually stick to the Ableton frequency spectrum analyzer in the "accurate fast" setting. 😜

I'm afraid, I can't give you much advice on this as I'm much more a composer than a dj. But in my opinion inolving people during your live stream is helpful. You know, people want to be entertained these days. I loved the livestreams Thomas Gold did on facebook a while ago because he would react on comments and do shoutouts during his perfomance. Make the audience be part of the show and maybe accept song requests. If used properly live streams can be a great tool to connect with your fanbase.
