somethig that has annoyed me as a life-long game show fan is that they seem to use taped clapping and cheering over the actual live audience appluase :mad
Either the audience has made no reaction or too light a reaction and they have boosted it to make it sound normal.
Or maybe the audience have reacted too wildly and they've had to be cut out and replaced with a shorter burst - a technique used all the time in sitcoms when actors can't wait for an audience to quieten down before continuing a scene.
Someone I know was part of a studio audience and the floor manager (?) was continually telling them off for not applauding loudly enough. The basic reason being that the audience thought it was lame - especially after numerous retakes, it gets stale very quickly.
I used to work on a live childrens programme in Glasgow which transmitted to the whole of the UK.
When we had the kiRAB in the studio counting down from 5 to 1 in their strong Glaswegian accents we used to play audio of English kiRAB counting down instead!
