Hi, does anybody know how to apply the fast-Fourier transform on
spectrum analysis?
When the application play the sound, it got the frequency wave shown,
while if there are no sound, the frequency wave will not be shown.
Does anybody have any idea on it? I try to search info about the fast-
fourier transform but unable to find the correct information.
If anybody knows about it, please help me.
Regards
Rainny
