Matlab design
dear all,
I'm trying to make some manipulations on audio signals, what I have to do is to save a signal of my voice (1s) then I add to it some sinus signals with 1khz 2khz 3khz and 4khz, then I must fiter the signal, is it normal that the frequency after filtring could be translated ( 1khz==>between 1020 and 1500 in fonction of filter order)? and even I find some strange resuults, my voice filtred sounds like nothing hehehe help me plz
