Soundtrack Generator is used to create soundtracks yourself by specifying which sound (from a list) should be played and when. The compositions thus produced can then be read via his telephone (or any other connected speaker) to perform the exercise that has been programmed.
No need to keep your eyes on the stopwatch or stay focused on your sheet to know when to whistle, the application does it for you, or tells you when you have to do it. It is therefore less stress during a VMA test for example, when it is necessary to answer a student while not missing the next whistle!
