NAME
mlib_SignalMelCepstralInit_S16, mlib_SignalMelCepstralInit_F32 - initialization for cepstral analysis in mel frequency scale SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_SignalMelCepstralInit_S16(void *state, mlib_s32 nlinear, mlib_s32 nmel, mlib_f32 melbgn, mlib_f32 melend, mlib_f32 meldiv, mlib_s32 order); mlib_status mlib_SignalMelCepstralInit_F32(void *state, mlib_s32 nlinear, mlib_s32 nmel, mlib_f32 melbgn, mlib_f32 melend, mlib_f32 meldiv, mlib_s32 order); DESCRIPTION
Each of these functions initializes the internal state structure for cepstral analysis in mel frequency scale. The init function performs internal state structure allocation and global initialization. Per function call initialization is done in each function, so the same internal state structure can be reused for multiplefunction calls. PARAMETERS
Each of the functions takes the following arguments: state Pointer to the internal state structure. nlinear The number of band pass filters in linear frequency scale. nmel The number of band pass filters in mel frequency scale. melbgn The begin radian frequency of the mel scale filter bank defined in linear frequency scale, where 0 <= melbgn < melend <= PI, melbgn is ignored if nlinear = 0. melend The end radian frequency of the mel scale filter bank defined in linear frequency scale, where 0 <= melbgn < melend <= PI. meldiv The dividing factor in linear to mel scale conversion, linear scale is measured in radians, with PI corresponding to half the sampling rate. order The order of the input signal vector and the cepstral coefficients, where length = 2**order. RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
