From Third Wish Software & Animation:
Magpie Pro is a powerful program that offers to the professional animator a set of tools to help him in lipsynching an animation. It was created in such a waythat lets the animator approach the task in many ways and according to his personaltaste and to the requirements of his company. It can be used to scrub the audio track and manually fill the exposure sheet frameby frame to obtain a highly detailed animation, or it can automatically analyze theaudio and fill the x-sheet. No matter what approach you decide to take, MagpiePro always provides a real time preview that gives an idea of how the animationwill look and helps fine tuning it even before creating it. Besides synching character mouths to audio tracks, Magpie Pro can be used tosync almost anything to the audio. It can also be used as a timing tool without theneed of an audio track. In all cases Magpie Pro provides export options to many3D animation programs, generates animation files with the preview contents andprints the exposure sheet so it can be used by traditional animators.
