  1. /* I wrote BIP because of a need to find specific sounds for my programming
  2.    needs. With this somewhat crude program I can find any sound I want without
  3.    programming and then later include the proper settings in my program. The
  4.    title BIP came from 'The Pink Panther'. The inspector would pronounce the
  5.    word BEEP as BIP.
  6.  
  7.    This program is given free of charge to everyone, without any warranty
  8.    expressed or implied. I will in no way be held responsible for any damages
  9.    of any kind (real or imaginary) caused by the use or misuse of this
  10.    program.
  11.  
  12.    Feel free to use any part of the following code for any purpose you
  13.    see fit. Just remember to leave the copyright notice in the BIP program.
  14.    Give credit where credit is due.
