Effacer les filtres

Sir, I have a resampled audio having sampling rate 2000hz in that i have to apply a antialiasing filter so how i will apply the antialiasing filter? The below code is i used for resampling the audio,

1 vue (au cours des 30 derniers jours)
if true
% code
end
[x, fs1] = audioread('audio3.wav');
%sound(x,fs1);
ts1=1/fs1;
N1=length(x);
Tmax1=(N1-1)*ts1;
t1=(0:ts1:Tmax1);
figure;
plot(t1,x),xlabel('Time'),title('audio1');
fs2 = (20/441)*fs1;
y=resample(x,2000,44100);
%sound(y,fs2);
ts2=1/fs1;
N2=length(y);
Tmax2=(N2-1)*ts2;
t2=(0:ts2:Tmax2);
figure;
plot(t2,y),xlabel('Time'),title('resampled audio1');
