Audio signal processing/audioread/fft. "Create a software tool for audio signal modulation. The signal read from the audio file should be modulated by the sine wave of the specified frequency. The software interface must allow the user to select the audio file and the sine wave frequency.
Doing a fft on a audio file - MATLAB & Simulink
https://www.mathworks.com/matlabcentral/answers/306187-doing-a-fft-on-a-audio-file
Hello, dear community! Really would appreciate a solution to my problem. i want to do a fft on a audio file, which duration last about 10 seconds. My goal is to make a fft on each seconds (1-10) and make it visible in a frequency- and time domain. So i can see, what happened in the last seconds and see the changes.

How do you plot the fft of an audio signal in matlab ...
https://dsp.stackexchange.com/questions/27374/how-do-you-plot-the-fft-of-an-audio-signal-in-matlab
(Quote borrowed from Mr. Grady in the movie The Shining.) Your y-axis label is correct but your plot title should be changed from "Amplitude" to "Magnitude". It makes a difference. In signal processing amplitude values can be positive or negative. Magnitude values are always positive and Matlab's abs() command always produces magnitude values ...
fft on samples of an audio file in matlab
https://la.mathworks.com/matlabcentral/answers/73337-fft-on-samples-of-an-audio-file-in-matlab
Accepted Answer. Where Fs is the sampling frecuency and y your audio samples. Knowing the sample frecuency you can find the number of samples in 2 seconds (2*Fs). Before performing the FFT algorithm of 2*Fs points you should apply some kind of windowing.You can find more about windows using doc window.
