Hi all,
I have encountered the issue with the hard disk, the disk is failed and need to replace by the new one.
As my understanding, this is just to take out the failed disk and insert the new ones, and that's all.

NAME
mlib_SignalLPCCovariance_S16, mlib_SignalLPCCovariance_S16_Adp - perform linear predictive coding with covariance method
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_SignalLPCCovariance_S16(mlib_s16 *coeff,
mlib_s32 cscale, const mlib_s16 *signal, void *state);
mlib_status mlib_SignalLPCCovariance_S16_Adp(mlib_s16 *coeff,
mlib_s32 *cscale, const mlib_s16 *signal, void *state);
DESCRIPTION
Each function performs linear predictive coding with covariance method.
In linear predictive coding (LPC) model, each speech sample is represented as a linear combination of the past M samples.
M
s(n) = SUM a(i) * s(n-i) + G * u(n)
i=1
where s(*) is the speech signal, u(*) is the excitation signal, and G is the gain constants, M is the order of the linear prediction fil-
ter. Given s(*), the goal is to find a set of coefficient a(*) that minimizes the prediction error e(*).
M
e(n) = s(n) - SUM a(i) * s(n-i)
i=1
In covariance method, the coefficients can be obtained by solving following set of linear equations.
M
SUM a(i) * c(i,k) = c(0,k), k=1,...,M
i=1
where
N-k-1
c(i,k) = SUM s(j) * s(j+k-i)
j=0
are the covariance coefficients of s(*), N is the length of the input speech vector.
Note that the covariance matrix R is a symmetric matrix, and the equations can be solved efficiently with Cholesky decomposition method.
See Fundamentals of Speech Recognition by Lawrence Rabiner and Biing-Hwang Juang, Prentice Hall, 1993.
Note for functions with adaptive scaling (with _Adp postfix), the scaling factor of the output data will be calculated based on the actual
data; for functions with non-adaptive scaling (without _Adp postfix), the user supplied scaling factor will be used and the output will be
saturated if necessary.
PARAMETERS
Each function takes the following arguments:
coeff The linear prediction coefficients.
cscale The scaling factor of the linear prediction coefficients, where actual_data = output_data * 2**(-scaling_factor).
signal The input signal vector with samples in Q15 format.
state Pointer to the internal state structure.
RETURN VALUES
Each function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
