You can plot FFT spectrum, Octave spectrum, 2D spectrogram, etc. and manage their corresponding settings for real-time audio spectrum analysis. For FFT spectrum analysis, you can set maximum and minimum frequency, FFT size, Min and Max amplitude in dB , etc. parameters to perform audio analysis for single channel or dual channel input.

Copy to Clipboard. Read it in with wavread () [signal,fs] = wavread ('file.wav'); If signal is Nx2 (two columns), extract one of them. signal = signal (:,1); If you have the Signal Processing Toolbox, enter. plot (psd (spectrum.periodogram,signal,'Fs',fs,'NFFT',length (signal)));
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".

In the oscilloscope demo, the plot shows the displacement of an audio signal versus the time, which is called the time-domain signal. This demo shows the signal represented in a different way: the frequency domain. The frequency spectrum is generated by applying a Fourier transform to the time-domain signal.

We are plotting frequencies ranging from 0 to 8kHz because our signal was sampled at 16k sampling rate and according to the Nyquist sampling theorem, it should only posses frequencies ≤ 8000Hz (16000/2). Strong frequencies are ranging from 0 to 1kHz only because this audio clip was human speech.
