Basic Spectral Analysis - MATLAB & Simulink
https://www.mathworks.com/help/matlab/math/basic-spectral-analysis.html
Read and plot the audio data. You can use the command sound (x,fs) to listen to the audio. whaleFile = 'bluewhale.au' ; [x,fs] = audioread (whaleFile); plot (x) xlabel ( 'Sample Number' ) ylabel ( 'Amplitude') The first sound is a "trill" followed by …
M- file for Audio spectral analysis - MATLAB & Simulink
https://www.mathworks.com/matlabcentral/fileexchange/8201-m-file-for-audio-spectral-analysis
Reviews (9) Discussions (3) The file is written for MATLAB 6.5 it aquires data from the sound card . Fourier spectral power analysis one second of audio signal sample is analyzed by simply running the M-file. The frequency contents of the voice analyzed are shown of a plot. I have used this program to compare voice qualities of many music starssome proved realy as …

This tutorial video describes the procedure for sound recording and FFT of the sound in Matlab...(This is enhanced version of previous one with better sound)...
viewing spectrum of an audio signal in matlab
https://www.mathworks.com/matlabcentral/answers/18357-viewing-spectrum-of-an-audio-signal-in-matlab
1 Link you should first read the audio signal using wavread () function. as a result of reading, the signal will be vectorized. after that, you should use fft () function to get the fourier transform of vectorized signal. at the end plot () the fourier transform of signal. sample code [xn fs]=wavread ('signal_name.wav');
Spectral rolloff point for audio signals and auditory ...
https://www.mathworks.com/help/audio/ref/spectralrolloffpoint.html
Read in an audio file, calculate the rolloff point using default parameters, and then plot the results. [audioIn,fs] = audioread( 'Counting-16-44p1-mono-15secs.wav' ); rolloffPoint = spectralRolloffPoint(audioIn,fs); t = …
De-Noising Audio using Spectral Subtraction in MATLAB …

It used the FFTW (Fastest Fourier Transform in the West)library for spectral analysis, just as MATLAB does now. The WaveWarpsoftware worked in standalone mode or as a DirectX plugin, and even had a real-time interface to …
MATLAB Assignment III April 2009 Audio EQ / Spectral Analysis
https://uweb.engr.arizona.edu/~429rns/hwassignments/EQ%20&%20Spectral%20Analysis.pdf
Write FIR-filter-based and IIR-filter-based Matlab functions that simulate the POP and DANCE audio tone-shaping graphic EQ (equalizer) systems shown below.1 Each design will be judged by viewing a plot of dB gain vs. frequency. FIREQ (EQ using FIR filters) Method: • Design the FIR EQ system for a music sampling rate of 44.1 kHz.
