The audio titled "Boom" starts with the echoing sound of a powerful and resonant explosion, akin to a sonic boom. This deep, pulsating sound effect sets a dramatic atmosphere instantly. Following the initial boom, there's a seamless transition into a series of whooshing sounds. These sounds are swift and sharp, like a gust of wind rushing past at high speed, creating a sense of rapid movement. This is then followed by a 'whoomp' sound, a lower, more muffled echo that seems to reverberate, as if in a large, hollow space. These sound effects blend together to create a vivid, dynamic audio experience, transporting the listener into a high-intensity, action-packed scenario.
