Put it at the very start of a clip, just before the main action, so it acts as the cue for everything that follows. Pair it with a whistle or air horn straight after it, then a cheering crowd once the winner is clear, keeping the countdown first and the celebration last.
关于此声音
This is a short spoken countdown that runs through three, two, one before bursting into a repeated go, go, go in just over four seconds. The quick build and sudden release give it a rush of excitement and anticipation, like the seconds before a race begins. It works as a burst of energy that lifts the mood and gets everyone ready to move at once.
