Do you have SoundEdit? Or the like?

I think I might make waveform bitmaps and then try and compare against the
current waveform (block EQ) - and if it's a close match, then fire off
specific vowel events. If that works, I could do consonants too. If this
works, I'll do jumping jacks and shots of Jack.

So how would I compare two bitmaps to see if a waveform (

If you need any of these files or can't find them, lmk and I can send off

Don't know if this will help, but have you looked into WaveAnalyzer.as or
Flash MX - Audio: Sound completion event (The source files for this can be
found in the Flash MX/Samples folder.)
They both let you control the sound. I am thinking this will point you in
a good direction. Its AS2 though.

HTH,

Ya - I have the data for both things, but they extend over time and are
difficult to compare. It's the boiling down the signatures into something simple and being able to read the playing audio looking for the match (or near match). I thought about using bitmap data and trying to match up waveforms, etc. but I don't know enough about it to pull that off. It
seems
like a hack in a way, but if it worked, who cares I suppose.

I'm not Henrik, but I've done some lip-synch stuff for Disney. We did it pretty much the way Eric described--we just used amplitude. It's not as accurate as Disney would demand on a film, but it's ok in the

I see, amplitudes could be just good enough for some stuff.

Although the "speed" and the intensitiy of the speech could give
misleading
results, I think. I'm under the impression that you should somehow try
to
compare the shape of the waves (somehow simplifiy your input to some
value
of sets of values that are easier to compare, possibly in a "time
window")
and compare it in some meaningful way to precalculated samples to find a
matching pattern. That's the part I have no clue about!

 Wow. That was really uncalled for.


That was my reaction, too. I didn't see Eric as complaining--just
asking. Maybe Henrik was just having a bad day.

For me, the hard part, which you seem to imply is rather simple here,

is

*matching+ the input audio against said profiles. Admitedly, I don't

know

anything about digital signal processing and audio programming in

general,

but "matching" sounds a bit vague. Perhaps you could enlighten us, I

you

feel like.

Doing something more accurate would probably involve at least 6 mouth positions, and if you're doing it in real time, you'd have to do a
reverse FFT. It can be done--there was a really good commercial
lip-synch program that generated Action Script to control mouth
positions. I don't know if it's still around--that was 5 years ago, and it was pretty expensive (about $2,500 for one seat, I think). It may even have been a Director Xtra that worked with a Flash Sprite,
but let's not talk about Director :-P

Cordially,
