How to Import Sound and Music into Flash:

• Go to File > Import to Library… Select your file.
• Open your Library window under Window > Library (Ctrl + L).
• Create a New Layer, I usually name it “AUDIO.”
• Extend the exposure by right-clicking down in the timeline and selecting Insert Frame. You can also use F5 to extend exposure.
• Drag your sound from the Library onto the Stage (the area where you draw).
• A waveform will appear in the timeline showing the audio has been added to your cartoon!

• IMPORTANT: Make sure your imported sound is set to “Stream” under the Properties window! (Window > Properties, or Ctrl + F3)
  

  Make sure to set your audio to Stream!

  This also allows you to ‘scrub’ the audio, meaning when you drag the playhead, you will hear the individual sounds of the audio, allowing you to lipsync each mouth shape!

Lipsync? What that mean?

• Lipsyncing is the process of animating mouths so the cartoon animation matches what is being said in the recorded dialogue.
• There are a handful of mouth shapes, which are called “Phonemes”.

• Each one represents different sounds we make when we talk. These are generally the same mouth shapes no matter what language is begin spoken!

Some guidelines when animating lipsync:

• MOVE THAT JAW! We are not bad 90’s anime cartoons! (Not that there’s anything wrong with that.)
• The top teeth do not move. They are attached to the skull.
• Hold a closed mouth shape for at least 2 frames, so it will read.
• Hold the last mouth shape for an extra 5-8 frames to make it look natural.
• If you have lengthy audio, like in a music video, use an external audio editing program like Audacity to split the audio into scenes. You can also use it to remove noise and improve your recording!
• Move your lipsync 2-3 frames earlier. This just makes it look better. The animation should happen before the sound happens. Think of it like light traveling faster than sound!
• Animate to the vowels, or the sounds, NOT to how the word is spelled. This is called “phrasing” and will make your lipsync not look so chattery.
