Hello
Sound sampling etc is an alien world to me - help! I have designed a board game - this is an example of what is needed:
A square on the board, which can be as high as the thickness of a button battery, is pressed and the sound of a train approaching is made for three seconds, finishing with EITHER the sound of a train crash, or the sound of a train whistle - the choice of either being a 50/50 chance.
Is this technically possible?
Thank you
Jason
