\section{Presentation of the "noise.dsp" Faust program}
This program describes a white noise generator with an interactive volume, using a random function.

\subsection{The random function}
The \texttt{random} function describes a generator of random numbers, which equation follows. You should notice hereby the use of an integer arithmetic on 32 bits, relying on integer wrapping for big numbers.
<equation>random</equation>

\subsection{The noise function}
The white noise then corresponds to:

</mdoc>

random  = +(12345)~*(1103515245);
noise   = random/2147483647.0;

<mdoc>
\subsection{Just add a user interface element to play volume!}
Endly, the sound level of this program is controlled by a user slider, which gives the following equation:
