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 …
Basic Spectral Analysis - MATLAB & Simulink
https://www.mathworks.com/help/matlab/math/basic-spectral-analysis.html
The Fourier transform of the signal identifies its frequency components. In MATLAB®, the fft function computes the Fourier transform using a fast Fourier transform algorithm. Use fft to compute the discrete Fourier transform of the signal. y = fft (x); Plot the power spectrum as a function of frequency.

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'); nf=1024; %number of point in DTFT.

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.
De-Noising Audio using Spectral Subtraction in MATLAB …

The spectral subtraction method, using a simple flat “white noise” model, is found to be rather effective in removing broad-band “tape hiss” noise from audio/music recordings. Compared with simple digital filtering (covered in the previous post), the spectral subtraction method is found to be superior (from informal subjective listening trials).
