How to add audacity mp3 file to a stop motion video with framebyframe?

I made a stopmotion with framebyframe, yes it's for mac. I was wondering how to add the audacity mp3 file to it so it will stream together and make it look like my video is talking. Like its playdough people and the mouths move. I also need to know how to make the timing perfect because counting and talking into the mike doesn't work. HELP!|||If you have your animation and sound already done, throw them together in a video editing program like Adobe Premiere, Final Cut Pro, iMovie, or Sony Vegas. If you don't have any of those and don't know how to get them, just use Windows Movie Maker.





But usually what's done is your audio is recorded first, then broken down to see how long each sound takes so you can then animate to that timing. That way when you put the sound and the video together afterwards, everything is in sync.





If you need any more help or info, let me know.
