matlab - Plotting amplitude spectrum of audio signal ...
https://stackoverflow.com/questions/40311246/plotting-amplitude-spectrum-of-audio-signal
Basically what i am doing is a real-time spectral analysis. To understand, what i mean, I advise you to try my code. Just take any WAV-File and put it in your matlab/octave directory. Anyway, the question is how do i get the amplitude spectrum from my audio signal? Btw, my one-sided spectrum signal is contained in the variable "Yres".
fft - How can I plot the spectrum of a signal in MATLAB ...
https://dsp.stackexchange.com/questions/36346/how-can-i-plot-the-spectrum-of-a-signal-in-matlab
spectrum = 10*log (abs (fftshift (fft (y))) / length (y)); %compute the FFT precision = fs/length (y); f = linspace (-fs/2+precision/2, fs/2-precision/2, length (y)); % Create the frequency axis and put the measure in the middle of the bin. plot (f,spectrum); And voilà. A little more explanation :
