Lip Syncing Your Animation
Getting your animation in sync with your audio has historically
been diffucult and time consuming. I found a little program
called Flash Amp that makes it much easier. Instead of trying
to match the mouth with the p's and the t's ect. the way most
books show you, Flash Amp uses a more simple approach. The program
measures the amptitude (loudness) of the sound file and creates
an array of numbers representing how loud each frame is in your
movie. You create a small movie for your mouth where each frame
represents how wide the mouth is open from closed to open.
In my movie, I used a ten frame mouth and a two frame eyebrow
movie, which I inserted in other movie clips representing my
characters. For this example, my characters were a boy and a
girl discussing the virtues of Adaptalap, which is one of my
customers.

Making your Sound Files
Besides Flash Amp and Flash, the only other software I used
was Windows sound recorder and WinAmp (free with Netscape).
I used Bell Labs' free "Text to Speech" Conversion
Tool on the Internet.
Since I didn't have any sound software other than what comes
with windows on my computer and the free audio software that
comes with the browsers, I did things a little differently than
I might have done with the correct software. If you have sound
software, you might find a simpler and quicker way to do some
of this stuff (the que array for example). If you have a better
way use it. I did what I could with what I had. I imagine, you
will do the same.
There are several text to speech software programs out there.
You could use one of them or use recording software to record
your own audio instead of using Bell Labs online program as
I did but it is free and easy. Be careful if you use Bell Labs
as they have a limitation of 40 files per day. I went over my
limit with two more files to make so I went to there other site
and luckily enough, it let me finish the last two. You can find
