Various shaped windows for sample frame conditioning, including cosine windows (Hann etc) and triangular and rectangular windows.

Constructor & Destructor Documentation

template<typename T>

Window< T >::Window ( WindowType  type, int  size  )

inline

Construct a windower of the given type and size.

Note that the cosine windows are periodic by design, rather than symmetrical. (A window of size N is equivalent to a symmetrical window of size N+1 with the final element missing.)
