Pseudo-Random generator

Type : Linear Congruential, 32bit
References : Hal Chamberlain, "Musical Applications of Microprocessors" (Posted by Phil Burk)
Notes :
This can be used to generate random numeric sequences or to synthesise a white noise audio signal.
If you only use some of the bits, use the most significant bits by shifting right.
Do not just mask off the low bits.
Code :
/* Calculate pseudo-random 32 bit number based on linear congruential method. */
unsigned long GenerateRandomNumber( void )
{
   /* Change this for different random sequences. */
   static unsigned long randSeed = 22222;
   randSeed = (randSeed * 196314165) + 907633515;
   return randSeed;
}
