title: Spectrum of a Frequency Modulated audio file(.mp3)
body: <p>steps: get the audio file and convert it to an array using:</p>
  <pre><code>def Convert_Audio_to_Array(self, FILE_NAME, fs=44100):
      print(&quot;Converting Audio File to Numpy Array...&quot;)
      audio_file, sr = librosa.load(os.path.join(self.BASE_DIR, FILE_NAME), sr=fs) # convert t0 numpy array
      print(f&quot;Conversion Successful with array/{audio_file.shape=}&quot;)
      return audio_file, sr
  </code></pre>
  <p>How do I plot its spectrum?</p>
