Files are provided in mp3 format. Here is how you can generate WAV-files yourself: 

  • Start your media player 
  • Start an audio editing and recording software like Adobe Audition
  • Run the mp3 file in the media player and run the audio editing software in record mode at the same time 
  • In this way you can obtain a WAV-copy of the real file. The fidelity is not the same as the original recording, but you can manipulate the WAV file, frequency analyze it etc..
