== File formats ===================

raw sound:
  .wav   (Microsoft)
  .au    (Next, Sun)
  .aiff  (Apple)

notes:
  .midi   (MIDI; depends on installed "instruments"; dry)  audio/midi
 
compressed:
  .mp3    (propietary but common)
  .ogg    (free, better, but not usually supported)

streaming formats
 .ram
 .mov

 Streaming Tip:
  The streaming formats are intended to let you hear it,
  but not to let you save it.  However, in a program like
  Audacity you can record from the input sound plug.
  So you can always use a mini-plug to mini-plug cable to 
  plug your output into your input...
