I just watch the highlight mini match of champions league last night. I watch it all 9 match, and a bit confused when hear all sound from supporter on stadium because all look the same.

you will hear a sound drum strings with the same tone, and sound cheers where almost the same when the player dribbling the ball almost in front of the goal.

I thing that champions league company just use that fake supporter sound to make their show to be lively, This can also affect the audience's interest to watch on each match because the company banded with their ads.

I just know that because there are some stadiums that do not have enough supporters, but the cheers sound already full lively with drum strings also.

what do you think?, is real or use recording through speakers
