Newbie level 2
first:load voice sample into matlab and plot the audio signal in time domain and in frequency domain
---------- Post added at 22:16 ---------- Previous post was at 22:11 ----------
second:increase the amplitude of all frequencies below 200hz and above 5 khz by factor 2 ' 5 and 10 then plot the fourier spectrum and time domain and describe the subjective change
---------- Post added at 22:27 ---------- Previous post was at 22:16 ----------
step3 in my project:take avoice sample of aperson and shit the freqquencies by factor two once up and once down plot again the fouries spectrum of the voice beor and fater shift i need help fast please
---------- Post added at 22:34 ---------- Previous post was at 22:27 ----------
fourth step :take avoice audio sample and square it in time domain then transfer it into freq domain and remove dc component
transfer it back to time domain and listen to it .
describe what the squaring has done
again plot the signal in time and freq domain
