Function Documentation

float ZCDECL *  zplfRealSum  ) 

calculate sum of vector

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

int ZCDECL *  zplfFFTCreateInstance  ) 

creates instance of FFT class

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_)
static int : not 0 in case of error

void ZCDECL *  zplfFree  ) 

free previously allocated memory and set pointer to 0

**ppfBuffer : address of pointer to memory
void :

float* ZCDECL* zplfMalloc int  iNumOfFloats  ) 

allocate heap memory (aligned if required)

iNumOfFloats : number of float32 to allocate
float* : pointer to memory

void zplVecLibDispatcher  ) 

has to be called to initialize zplVecLib (mandatory!)

void zplVecLibDispatcher :
