Morning: Editing audio with Audacity (hands-on); this is a free program that works on Windows and Mac. We use Switch to convert WMA audio files to the WAV format (uncompressed), because Audacity cannot open a WMA file. Make sure your recorder can save files in one of these formats: WMA, WAV or MP3.
