DESCRIPTION

24       Each of these functions initializes the internal  state  structure  for
25       cepstral analysis in mel frequency scale.
26
27
28       The  init  function  performs  internal  state structure allocation and
29       global initialization. Per function call initialization is done in each
30       function, so the same internal state structure can be reused for multi‐
31       plefunction calls.
32

PARAMETERS

34       Each of the functions takes the following arguments:
35
36       state      Pointer to the internal state structure.
37
38
39       nlinear    The number of band pass filters in linear frequency scale.
40
41
42       nmel       The number of band pass filters in mel frequency scale.
43
44
45       melbgn     The begin radian frequency of  the  mel  scale  filter  bank
46                  defined in linear frequency scale, where 0 ≤ melbgn < melend
47                  ≤ PI, melbgn is ignored if nlinear = 0.
48
49
50       melend     The end radian  frequency  of  the  mel  scale  filter  bank
51                  defined in linear frequency scale, where 0 ≤ melbgn < melend
52                  ≤ PI.
53
54
55       meldiv     The dividing factor in linear to mel scale conversion,  lin‐
56                  ear  scale  is measured in radians, with PI corresponding to
57                  half the sampling rate.
58
59
60       order      The order of the input signal vector and the cepstral  coef‐
61                  ficients, where length = 2**order.
62
63

RETURN VALUES

65       Each  of the functions returns MLIB_SUCCESS if successful. Otherwise it
66       returns MLIB_FAILURE.
