We discussed in the first chapter how Audacity can save files in many file formats. When you save a project, it is saved as an AUP, or Audacity Project, file with a corresponding folder with the same name as the project, which contains all of the additional project files.

AIFF (Apple) signed 16 bit PCM
WAV (Windows) signed 16 bit PCM
