title: Convert from PCM to WAV. Is it Possible?
body: <p>I have an application for iPAD.
  This application records the voice of the microphone.
  The audio formats of the item must be PCM, MP3 and WAV files. The MP3 file I get it starting from the original raw file and then convert using LAME.
  Unfortunately I have not found any example that allows me to convert a PCM file to a WAV file.
  I just noticed that if I put the file extension to WAV format, starting from the raw application saves without problems, so I think that there is no type conversion from PCM WAV files.
  Correct?</p>
