NAME
mlib_SignalQuant_S16S_F32S - float to 16-bit quantization
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_SignalQuant_S16S_F32S(mlib_s16 *dst, const mlib_f32 *src, const mlib_f32 *thresh, mlib_s32 n);
DESCRIPTION
The mlib_SignalQuant_S16S_F32S() function quantizes a signal array by using the following equation:
X = x(n) n = 0, 1, ...
Z = z(n) n = 0, 1, ...
= -32768 for x(n) < t(-32768)
= k for t(k) <= x(n) < t(k+1)
= +32767 for x(n) >= t(+32767)
PARAMETERS
The function takes the following arguments:
dst Output signal array in two-channel interleaved stereo format.
src Input signal array in two-channel interleaved stereo format.
thresh Array of 65536 thresholds.
n Number of samples in the input signal array.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
