spectral_analysis

This function computes the Fast Fourier transform of an input audio file data and plots it on the frequency axis.

This function computes the discrete Fourier transform of an input audio signal using the Fast Fourier Transform algorithm built into Matlab's fft() function as part of the signal processing toolbox.

The inputs are the data extracted from any audio file. The audio data and the sampling rate should be extracted from the audio and passed to this function.
Ex : [audio_data, sample_rate] = audioread('test.mp3');
Also, the title that should appear on the plot of the fft is to passed as a string

Ex : spectral_analysis(audio_data, sample_rate,"FFT Plot")
