normalizes audio so that the maximum absolute value of its samples is 1.

normalizes samples so that the maximum absolute value of samples is s.


  • AudioNormalize[audio,s] implements peak normalization. All samples are rescaled using the same scaling factor s/TemplateBox[{peak}, Abs], where peak is a sample value with the highest absolute value.
  • The parameter s should be a non-negative real number, typically between 0 and 1.
  • AudioNormalize[audio] is equivalent to AudioNormalize[audio,1].
