NAME
       mlib_SignalQuant_U8S_F32S - float to 8-bit quantization

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_SignalQuant_U8S_F32S(mlib_u8 *dst,
	    const mlib_f32 *src, const mlib_f32 *thresh, mlib_s32 n);

DESCRIPTION
       The mlib_SignalQuant_U8S_F32S() function quantizes a signal array by using the following equation:

	 X = x(n)  n = 0, 1, ...
	 Z = z(n)  n = 0, 1, ...
	   =   0   for x(n) < t(0)
	   =   k   for t(k) <= x(n) < t(k+1)
	   = 255   for x(n) >= t(255)

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 256 thresholds.

       n	 Number of samples in the input signal array.

RETURN VALUES
       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
