[y,Fs]=audioread('audio.wav');
% define cutoff frequencies
fc1=?
fc2=?
bandpass(y,[fc1 fc2],fs);
Similar answer is avaliable here, please check, detail documentation

a=('audio_signal.wav');
[y,fs]=audioread(a);
sound(y,fs);
figure(1);
plot(y);
spec=abs(fftshift(fft(y)));
Nfft=numel(y);
c=linspace(-fs/2,fs/2,Nfft);
plot(c,spec);
q=bandpass(spec,[2500 5000],fs);
figure(2);
plot(q)
what is wrong in this coding?
