Life is not always as it seems, and this is particularly true in the world of film and television. Whilst we’re all used to the computerised visual effects used in modern films, we are probably not as aware of the level of special effects used in the film’s soundtrack.
Special effects has two categories, mechanial & natural.Natural sounds,The natural sounds....
Can be directly recorded from the location or same situation created by the crews.
The rest is mechanical,tht can created by the 'Archives' of sound effects[pre-recorded]
with the help of an hard disk media like computers...

Any modern blockbuster film will invariably be liberally splattered with awesome special visual effects . We’ve come to expect it. However, while our eyes are being bombarded with spectacular visual sequences our ears are also being attacked with a host of auditory stimuli to trick us into believing what we see is real.

The audio production of a film never attracts the same kudos as the visual effects. Yet, get it wrong and the visual sequence just won’t have the same impact. Get it right however and you’re transported into a different world completely. It’s all smoke and mirrors!
