hello I want to get a live fft of my live audio signal. this my code , how ever my fft is wrong . could some one explain my why ?
clc;
clear all;
close all;
recorder = audiorecorder(96000, 24, 1);
disp('Start speaking.')
recorder.record(5);
while recorder.isrecording()
pause(0.1);
subplot(2,1,1);
plot(recorder.getaudiodata());
title('live recording of sound(t)')
y=getaudiodata(recorder);
fft_getaudio=fft(y,length(y));
subplot(2,1,2);
plot(linspace(0,5,length(y)),fft_getaudio);
title('live recording of fft (sound(t))')
drawnow();
end
disp('End of Recording.');

Check the documentation of fft function and modify their example. There are a lot of things that are wrong in your implementation.
