_SndPlayFile not starting sound file

[Dimster]

I have a stupid question regarding an MP3 sound file...if sound is in waves and the waves repeat in identical frequency, amplitude etc, to reduce the size of the file could you not remove those waves which repeat an identical pattern. You could then load into your program the essences of the MP3 sound and have your program play that sound over and over again to the time of the original MP3 sound file??? or this pretty well impossible to do.
