Actually, the FAA or NTSB rarely release CVR or communications audio, especially where the sound of the doomed screaming or impact are involved, only transcripts. I see no value, in fact I only see perverse curiosity, in listening to the family of the pilot screaming in the background as he calls out his final epitaph. Folks who get excited about such things have ample other places to go on the internet, Brazilian news cameras following suicide jumpers all the way down to the pavement, horrible accident scenes on Russian dash cams, ISIS recruitment videos, etc., and we not feed such perverted appetites here.
