Hi lads ,

I want to ask how can ı apply band bass signal an audio file which is 'wav'.

Thank you sir bu ı dont understand last part little fs should Fs is it because our sampling frequency is defined in the audio wav file

Answer 1

[KALYAN ACHARJYA]

[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?
