Synchronizing audio with animation usually requires marking particular frames. Markers let you delimit different portions
of the audio clip and give their wave patterns a corresponding meaningful name to help you sync more easily with the animation.
Markers appear as red lines and as gray boxes below the clip in the mixer.
Move the playback cursor to the portion of audio wave you want to mark. Create markers with the Create Marker tool by pressing
the M key, then dragging over a range of frames on the clip — see Marking Frames on Clips.
Adjust the animation of the character (such as shape animation) to match the marked audio waveforms.
When you're satisfied with the results, do a final render and use an editing suite to add the sound to the animation.
