SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlib_status mlib_SignalConv_S16_S16_Sat(mlib_s16 *dst,
          const mlib_s16 *src1, const mlib_s16 *src2, mlib_s32 m,
          mlib_s32 n);


     mlib_status mlib_SignalConv_S16S_S16S_Sat(mlib_s16 *dst,
          const mlib_s16 *src1, const mlib_s16 *src2, mlib_s32 m,
          mlib_s32 n);


     mlib_status mlib_SignalConv_F32_F32(mlib_f32 *dst,
          const mlib_f32 *src1, const mlib_f32 *src2, mlib_s32 m,
          mlib_s32 n);


     mlib_status mlib_SignalConv_F32S_F32S(mlib_f32 *dst,
          const mlib_f32 *src1, const mlib_f32 *src2, mlib_s32 m,
          mlib_s32 n);


DESCRIPTION
     Each of these functions performs convolution.


     For monaural signals, the following equation is used:

                m-1
       dst[i] = SUM (src1[j] * src2[i - j])  if m < n
                j=0

                n-1
       dst[i] = SUM (src2[j] * src1[i - j])  if m > n
                j=0



     where i = 0, 1, ..., (m + n - 2).


     For stereo signals, the following equation is used:

                      m-1
       dst[2*i]     = SUM (src1[2*j] * src2[2*(i - j)])

                      j=0

                      m-1
       dst[2*i + 1] = SUM (src1[2*j + 1] * src2[2*(i - j) + 1])
                      j=0



     if m < n, or

                      n-1
       dst[2*i]     = SUM (src2[2*j] * src1[2*(i - j)])
                      j=0

                      n-1
       dst[2*i + 1] = SUM (src2[2*j + 1] * src1[2*(i - j) + 1])
                      j=0



     if m > n; where i = 0, 1, ..., (m + n - 2).

PARAMETERS
     Each of the functions takes the following arguments:

     dst     Destination signal array.


     src1    First source signal array.


     src2    Second source signal array.


     m       Number of samples in the first source signal array.


     n       Number  of  samples  in  the  second  source  signal
             arrays.


RETURN VALUES
     Each of the functions returns  MLIB_SUCCESS  if  successful.
     Otherwise it returns MLIB_FAILURE.
