Ah fair enough. Luckily I feel like noticeable crowds are pretty rare on live albums unless the band itself isn't too heavy. Usually it's just between songs you hear them, especially metal when you always get some drunk dude going "AARRRRGGGHHHH!!!!!!!" between songs lmfao. There's a Norwegian grind band called Tottal Tømming and at times it sounds like the room is full of tards on their live album.
Personally what I really like is when you get the crowd engaging in singalongs and chants or hand-clapping at the command of the singer, but that's pretty rare.
