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 *  zplfFFTCreateInstance  )

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 *  zplfFree  )

free previously allocated memory and set pointer to 0 Parameters: **ppfBuffer  : address of pointer to memory 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

void zplVecLibDispatcher (   )

has to be called to initialize zplVecLib (mandatory!) Parameters: none  Returns: void zplVecLibDispatcher : Definition at line 77 of file FEAPIExamplePluginLoudness/zplVecLibDispatch.cpp.
