How can I find the maximum frequency component of an audio signal? I have used the following code so please tell me how can I point out the max freq component by the graph of abs(xfft)? If there is any other way to find it, do share it. Thanks!
[y Fs]=wavread(filename); xfft=fft(y); plot(abs(xfft));
