NAME
mlib_SignalEmphasize_S16_S16_Sat, mlib_SignalEmphasize_S16S_S16S_Sat, mlib_SignalEmphasize_F32_F32, mlib_SignalEmphasize_F32S_F32S - signal pre-emphasizing SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_SignalEmphasize_S16_S16_Sat(mlib_s16 *dst, const mlib_s16 *src, void *filter, mlib_s32 n); mlib_status mlib_SignalEmphasize_S16S_S16S_Sat(mlib_s16 *dst, const mlib_s16 *src, void *filter, mlib_s32 n); mlib_status mlib_SignalEmphasize_F32_F32(mlib_f32 *dst, const mlib_f32 *src, void *filter, mlib_s32 n); mlib_status mlib_SignalEmphasize_F32S_F32S(mlib_f32 *dst, const mlib_f32 *src, void *filter, mlib_s32 n); DESCRIPTION
Each of these functions applies the preemphasizer to one signal packet and updates the filter states. For monaural signals, the following equation is used: dst[i] = src[i] - alpha*src[i - 1] where i = 0, 1, ..., (n - 1); src[-1] = 0. For stereo signals, the following equation is used: dst[2*i] = src[2*i] - alpha*src[2*(i - 1)] dst[2*i + 1] = src[2*i + 1] - alpha*src[2*(i - 1) + 1] where i = 0, 1, ..., (n - 1); src[-2] = src[-1] = 0. PARAMETERS
Each of the functions takes the following arguments: dst Destination signal array. src Source signal array. filter Internal filter structure. n Number of samples in the source signal array. RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

NAME
mlib_SignalUpSample_S16_S16, mlib_SignalUpSample_S16S_S16S, mlib_SignalUpSample_F32_F32, mlib_SignalUpSample_F32S_F32S - signal upsampling SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_SignalUpSample_S16_S16(mlib_s16 *dst, const mlib_s16 *src, mlib_s32 factor, mlib_s32 phase, mlib_s32 n); mlib_status mlib_SignalUpSample_S16S_S16S(mlib_s16 *dst, const mlib_s16 *src, mlib_s32 factor, mlib_s32 phase, mlib_s32 n); mlib_status mlib_SignalUpSample_F32_F32(mlib_f32 *dst, const mlib_f32 *src, mlib_s32 factor, mlib_s32 phase, mlib_s32 n); mlib_status mlib_SignalUpSample_F32S_F32S(mlib_f32 *dst, const mlib_f32 *src, mlib_s32 factor, mlib_s32 phase, mlib_s32 n); DESCRIPTION
Each of these functions performs upsampling. For monaural signals, the following equation is used: dst[i] = src[k] if i == k*factor + phase dst[i] = 0 if i != k*factor + phase where k = 0, 1, ..., (n - 1); i = 0, 1, ..., (n*factor - 1). For stereo signals, the following equation is used: dst[2*i] = src[2*k] if i == k*factor + phase dst[2*i] = 0 if i != k*factor + phase dst[2*i + 1] = src[2*k + 1] if i == k*factor + phase dst[2*i + 1] = 0 if i != k*factor + phase where k = 0, 1, ..., (n - 1); i = 0, 1, ..., (n*factor - 1). PARAMETERS
Each of the functions takes the following arguments: dst Output signal array. src Input signal array. factor Factor by which to upsample. factor >= 1. phase Parameter that determines relative position of an input value, within the output signal. 0 <= phase < factor. n Number of samples in the input signal array. RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
