class_docstr: Abstract base class for colored noise
  
  This contains several noise generator that generating different colored
  noise given the desired type and the length of clip data for degrading
code: def audio(self, mudabox, state):
      weight = state["weight"]
      color = state["color"]
  
      # Generating the noise data
      noise = noise_generator(
          mudabox._audio["y"], mudabox._audio["sr"], color, self._rng
      )
  
      # Normalize the data
      mudabox._audio["y"] = librosa.util.normalize(mudabox._audio["y"])
      noise = librosa.util.normalize(noise)
  
      mudabox._audio["y"] = (1.0 - weight) * mudabox._audio[
          "y"
      ] + weight * noise
