mlib_SignalQuant_S16_F32 - float to 16-bit quantization SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_SignalQuant_S16_F32(mlib_s16 *dst, const mlib_f32 *src, const mlib_f32 *thresh, mlib_s32 n); DESCRIPTION
The mlib_SignalQuant_S16_F32() 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 src Input signal array . 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. ATTRIBUTES
