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 ( On Thu, Jun 3, 2010 at 5:18 PM, Karl DeSaulniers <k...@designdrumm.com>wrote: > If you need any of these files or can't find them, lmk and I can send off > list. > > Best, > > Karl > > > > On Jun 3, 2010, at 3:37 PM, Karl DeSaulniers wrote: > > 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.
