mlib_SignalLPCPerceptWeight_F32 - perform perceptual weighting on input signal SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_SignalLPCPerceptWeight_F32(mlib_f32 *sigwgt, const mlib_f32 *signal, const mlib_f32 *lpc, mlib_f32 r1, mlib_f32 r2, void *state); DESCRIPTION
The mlib_SignalLPCPerceptWeight_F32() function performs perceptual weighting on input signal. The perceptual weighting filter is defined as following. A(z*r1) W(z) = --------- A(z*r2) where A(z) is the inverse filter M -i A(z) = 1 - SUM a(i) * z i=1 See G.723.1, G.728, G.729, G.729A, GSM EFR standards. PARAMETERS
The function takes the following arguments: sigwgt The weighted signal vector. signal The input signal vector. lpc The linear prediction coefficients. r1 The perceptual weighting filter coefficient, it is treated as 1 if 0 is supplied. r2 The perceptual weighting filter coefficient, it is treated as 1 if 0 is supplied. state Pointer to the internal state structure. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
