It's very possible that the animation is done to 'placeholder audio'.  The full process isn't discussed much except maybe in more exclusive circles one supposes.  Obviously, the entire cadence (audio and video) has to be considered in the creation of the animation.  But I can't believe that one is more dependent upon the other to such an extent as being portrayed here - as in, 'Make the animation fit this audio or else'.  That would be suicidal. ;)

If you have the audio you want and need to create the animation around it, be prepared to do a lot of tweaking to gain synchronization.  With properly done animation, the alternative of fitting the audio would appear to be less work.  The best bet with Poser would be to be prepared to select columnar sets of keyframes and slide them backward or forward in time to achieve this after doing the general animation.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
