Hi guys , i need some advice/tips/guidance. Pls share.
So , i am supose to design a low pass filter with a certain cutoff frequency
and i'm suppose to filter those high frequency component of the sound in time domain(convolution) and freq domain(multiplication).
So , i am not sure how to do it..i took a snippet from some song , at about 2sec.
How do i filter out the high frequency component??
i written a low pass filter code. : ( not sure issit like this or not , help me check pls )
cf = 2000;
n = [0:997];
t = n/cf;
N = length(t);
f = n*cf/N;
hf = [ones(1,333) zeros(1,333) ones(1,332)];
i do not know whats next... pls show some guidance.
