Power spectrum of audio signal - MathWorks
https://la.mathworks.com/matlabcentral/answers/495370-power-spectrum-of-audio-signal
To import the audio file into MATLAB workspace, use the ‘audioread’ function. Refer to the link below to get the details of ‘audioread’ function: The first link gives examples of power spectrum computation for audio signals. The second link is about the ‘dspdata.psd’ function which computes the power spectral density.
Frequency spectrum of a sound signal - MATLAB & Simulink
https://in.mathworks.com/matlabcentral/answers/486379-frequency-spectrum-of-a-sound-signal
Hi guys, I would like to know some hints on how to plot frequency spectrum of magnitude and phase spectra of an audio signal in both omega and frequency as x-axis parameter (plot separately). Thanks. My code is as below and i'm not sure what's going on.
Module 5: Record Audio Signals in MATLAB
https://catalyst2019.github.io/files/Module5-record-audio.pdf
If you execute the MATLAB command y = record_audio(sec,FS,InpID); then you are recording for secseconds with a sampling rate of FS. The result of the recording will be stored in the vector y. Define sec=3and FS=44100and execute the above command. After pressing enter, speak into the microphone, as this command starts recording almost immediately.

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".
