Taking as an example that I want to record my voice. How does it appear in the frequency spectrum? Can I also view it on other spectra?

    $\begingroup$ Hello Luca Leone and welcome to DSP SE. Your question is way too broad for someone to be able to answer it without having to cover a huge amount of Signal Processing topics. I suggest you divide your question down to more questions with a clear cut and concise problem. $\endgroup$

  • $\begingroup$ You can "always" monitor your recorded data in the frequency domain. You can use the Discrete Fourier Transform (an implementation of the Fast Fourier Transform - FFT) to go from the time-domain to the frequency-domain. $\endgroup$
