Hi, I am working on speech recognition and restoration. I read an audio file to matlab and convert it to frequency domain by taking the FFT to the audio signal. Now I wont to analyses of the signal by Mel map and wavelet. please can someone help me ? I don't know how can I do this in matlab.....
%Read the data to the MATLAB using audioread.
[y,fs] = audioread('filename');
y_fft=abs(fft(y));
% plot the signal in frequency domain
n=length(y)-1
f=0:fs/n:fs;
figure;
plot(f,y_fft);
xlabel('Frequency in Hz');
ylabel('Magnitude');
title('The Wave FFT');
