Digital Xoover with infinite slope

[danyele]

Using a PC it's possible to make a xoover with infinite slope (cutting the FFT of the signal).
someone have use this method in a sistem?

With this metod ther aren't interfecences between the loudspeakers.

Calculating the fft of the signal it's possible to cut the fft of the signal and calculating the i-fft we have the signal cutted with infinite slope and without modify the fase.
Ther'are a problems with this method? 😕

I guess there won`t be a perfect matching between the two ways and so there will be FFT artefacts (ringing). Probably you are better off with eliptic filters.
