No. Windowing can't be used in batch processing what is a essentially a
continuous data stream.

Read up and get it straight, then. It's what makes windowing unnecessary
and unwanted. There are good books and web sites.

hi to everyone,
I need to find WORKING dsp routines, that is, not vague or damned
crypted or totaly wrong routines ( usually these are find in most books).
By the way , I want implement a simple ( for you,not for me)
procedure to do FFT convolution of large signals ,so I think I must
windowing segments of the signal ,
to make the convolution and to use some type of overlap in order to obtain
the filtred signal (and , I hope , to find a way to control if the result is
right because the
overlap totaly confuse me).
Someone has advised to me " C++ Language Algorithms for Digital Signal
Processing" Paul Embree.
Do you think it is appropriate for this ?
Do you know a better one ?
Thank you for your help.
