White Noise Generator

The FAUST noise generator defined in noises.lib is an instructive example. It generates uniform pseudo-random white noise in $[0,1)$ by the linear congruential method.¹²

    random = +(12345) ~ *(1103515245); // overflowing mpy & offset
    RANDMAX = 2147483647.0;
    noise = random / RANDMAX;

Note that for this noise-generator to give identical results on all platforms, FAUST must define integers as 32 bits everywhere, and overflow behavior must be normalized across platforms as well.
