i am adding gaussian noise signal to an audio signal. but in plotting i am receiving an error " ??? Error using ==> plot Vectors must be the same lengths" how can i make equal vectors?
[y,fs,nbits]=wavread('C:\Users\HP\Desktop\s1.wav'); n=randn(size(y))*sigma+mu*ones(size(y)); ny=length(y); ...

i want frequency domain spectrum of an audio file and i want to set frequency range of about 3 kHz. it is showing range upto 10 kHz. how can i modify it?
yfft=fft(y); % fft of original signal N=length(y); f=(-1/2:1/N:1/2-1/N)*fs; plot(f,k);

i want frequency domain spectrum of an audio file but i am getting amplitude range upto 0-6000. how can i normalize it? sampling rate is 48kHz
[y,fs,nbits]=wavread('C:\Users\HP\Desktop\s1.wav'); N = length(y); f = (-1/2:1/N:1/2-1/N)*fs; plot(f,abs(yfft));

i want frequency domain spectrum of an audio file but i am not getting right frequency range. it is showing freq. range upto 100 kHz but i want to get it upto 10 kHz. what is the problem in frequency range?
yfft=fft(y); % fft of original signal f=-length(y)/2:length(y)/2-1; k=20*log10(abs(yfft)); plot(f,k);
