Ah yes, it's possible to figure out how to time animation with Audacity.
What I've done is put my audio into Audacity, then select the space between two points in the audio which I want something to happen between. There's three boxes along the bottom with numbers. In the middle box, make sure "Length" is selected and your units are in "hh:mm:ss + hundredths" (click on the little arrow to change it). Then take the number shown in this box and multiply it by your framerate. This will give you the number of frames between those two points in the audio (round to the nearest frame). When you animate, you will know how long to make the movement/pause so that it's synced to the audio.
However, unless you're doing mouth animation, you don't have to use that for dialog. What I do in my head is divide the line up into pieces (usually between punctuation marks, words like "and", or on emphasized words) and think of a movement to animate for each one. I try to break it up so the same movement isn't repeated too much in the same shot. After I film it, I add pauses between the movements, saying the line out loud to make sure I have the timing right. Then, in my editing program, I put the audio where it fits best.
Not literally dead, just no longer interested in Lego or animation.
