Constructor & Destructor Documentation

SincWindow()

SincWindow::SincWindow ( int  length, double  p  )

inline

Construct a windower of the given length, containing the values of sinc(x) with x=0 in the middle, i.e. at sample (length-1)/2 for odd or (length/2)+1 for even length, such that the distance from -pi to pi (the nearest zero crossings either side of the peak) is p samples.
