Function Documentation

float (  ZCDECL *  zplfRealSum  )

calculate sum of vector Parameters: *pfSrc  : pointer to buffer for which the sum value is calulated iLengthAsPowOf4  : length of buffer in float32 values Returns: float : sum over all values

int (  ZCDECL *  zplfFFTDestroyInstance  )

creates instance of FFT class Parameters: pCFFT  : handle to the new class iBlockLength  : audio input block length in floats iZeroPadFactor  : zeropad factor (example: if iBlockLength = 1024 and iZeroPadFactor = 4, the size of the zeropadded FFT will be 4096) eWindowType  : window to be used (see CzplfFFT::_Fft_Windows_) Returns: static int : not 0 in case of error

void (  ZCDECL *  zplfCompAbs  )

calculate absolute value of buffer containing complex values Parameters: *pfDest  : pointer to buffer the result will be written into *pfSrcDest  : pointer to buffer for which the absolute values are calulated iRealLengthAsPowOf4  : number of real values (for zCOMPLEX==zFLOAT: half the complete buffer length in floats, real value R(N/2) is discarded) Returns: void :

float* ZCDECL* zplfMalloc (  int  iNumOfFloats  )

allocate heap memory (aligned if required) Parameters: iNumOfFloats  : number of float32 to allocate Returns: float* : pointer to memory Referenced by zplVecLibDispatcher().

void zplVecLibDispatcher (   )

has to be called to initialize zplVecLib (mandatory!) Parameters: none  Returns: void zplVecLibDispatcher : Definition at line 77 of file FEAPIExamplePluginLoudness/zplVecLibDispatch.cpp. Referenced by CLoudness::CLoudness(), CSpectralFeatures::CSpectralFeatures(), and CZeroCrossings::CZeroCrossings().
