µ-law expansion
Synopsis
#include <filter.h>
void mu_expand(in, out, n)
const short in[];

int n;
Description
The
mu_expand
ples and expands them according to ITU recommendation G.711. Each
input value is expanded to a linear 14-bit signed sample in accordance
with the µ-law definition and is returned in the vector pointed to
Algorithm
C(k)= mu_law expansion of A(k)
for k=0 to n-1
Domain
