DESCRIPTION

31       Each  of these functions applies the preemphasizer to one signal packet
32       and updates the filter states.
33
34
35       For monaural signals, the following equation is used:
36
37         dst[i] = src[i] - alpha*src[i - 1]
38
39
40
41       where i = 0, 1, ..., (n - 1); src[-1] = 0.
42
43
44       For stereo signals, the following equation is used:
45
46         dst[2*i]     = src[2*i]     - alpha*src[2*(i - 1)]
47         dst[2*i + 1] = src[2*i + 1] - alpha*src[2*(i - 1) + 1]
48
49
50
51       where i = 0, 1, ..., (n - 1); src[-2] = src[-1] = 0.
52

PARAMETERS

54       Each of the functions takes the following arguments:
55
56       dst       Destination signal array.
57
58
59       src       Source signal array.
60
61
62       filter    Internal filter structure.
63
64
65       n         Number of samples in the source signal array.
66
67

RETURN VALUES

69       Each of the functions returns MLIB_SUCCESS if successful. Otherwise  it
70       returns MLIB_FAILURE.
