Modifying the Parabolic SAR

 
I would like to request help in modifying the Parabolic SAR indicator. This should be easy for someone who is familiar with the programing language. I can trade but am brain dead when it comes to programing language. I would like the Parabolic SAR to emit an audible signal when it flips to the other side of the candle stick. Any help would be greatly appreciated. Thanks,
