NAME
mlib_SignalQuant2_S16_F32 - float to 16-bit quantization
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_SignalQuant2_S16_F32(mlib_s16 *dst, const mlib_f32 *src, const mlib_f32 thresh, mlib_s32 length, mlib_s16 offset, mlib_s32
n);
DESCRIPTION
The mlib_SignalQuant2_S16_F32() function quantizes a signal array by using the following equation:
X = x(n) n = 0, 1, ...
Z = z(n) n = 0, 1, ...
= offset for x(n) < t(0)
= offset + k for t(k) <= x(n) < t(k+1)
= offset + length - 1 for x(n) >= t(length - 1)
PARAMETERS
The function takes the following arguments:
dst Output signal array
src Input signal array .
thresh Array of thresholds.
length Length of the array of thresholds.
offset Offset for thresholds.
n Number of samples in the input signal array.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
