NAME
mlib_SignalConv_S16_S16_Sat, mlib_SignalConv_S16S_S16S_Sat, mlib_SignalConv_F32_F32, mlib_SignalConv_F32S_F32S - signal convolution SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> 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. ATTRIBUTES

NAME
mlib_SignalCrossCorrel_S16, mlib_SignalCrossCorrel_S16S, mlib_SignalCrossCorrel_F32, mlib_SignalCrossCorrel_F32S - signal cross correlation SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_SignalCrossCorrel_S16(mlib_d64 *correl, const mlib_s16 *src1, const mlib_s16 *src2, mlib_s32 n); mlib_status mlib_SignalCrossCorrel_S16S(mlib_d64 *correl, const mlib_s16 *src1, const mlib_s16 *src2, mlib_s32 n); mlib_status mlib_SignalCrossCorrel_F32(mlib_d64 *correl, const mlib_f32 *src1, const mlib_f32 *src2, mlib_s32 n); mlib_status mlib_SignalCrossCorrel_F32S(mlib_d64 *correl, const mlib_f32 *src1, const mlib_f32 *src2, mlib_s32 n); DESCRIPTION
Each of these functions performs cross correlation. For monaural signals, the following equation is used: 1 n-1 correl[0] = --- * SUM (src1[i] * src2[i]) n i=0 For stereo signals, the following equation is used: 1 n-1 correl[0] = --- * SUM (src1[2*i] * src2[2*i]) n i=0 1 n-1 correl[1] = --- * SUM (src1[2*i + 1] * src2[2*i + 1]) n i=0 PARAMETERS
Each of the functions takes the following arguments: correl Pointer to the cross correlation array. In the stereo version, correl[0] contains the cross correlation of channel 0, and cor- rel[1] contains the cross correlation of channel 1. src1 First source signal array. src2 Second source signal array. n Number of samples in the source signal arrays. RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
