I'm not ASL user nor programmer or anything like, but this is COOL. Could you explain how it works more in layman's terms?
I'm not very good at explaining things but let me try...
Have a look at this good demonstrational video:
=15s - although it's about circuit the method is near exactly the same used by me
- each 'peak' is called 'band' thus I'm using 'bandpass filter' for several times to extract each band from the whole audio during the process I mentioned
- the frequencies that are written under the each peak (and being heard during the presentation) are the ones used in his audio analyzer (note that I'm using the same ones except for the two lowest and one highest)
- the frequencies are 'a' parameter mentioned in step 3
- if you only need to extract beat or overall loudness of sound you can reduce the number of required steps significantly (even down to only 1. opening the file in Wavosaur, 2. applying a single lowpass/bandpass filter only (or even not), 3. downsampling to 24, 25 or 30 Hz = always equal to number of frames per second in your animation, 4. saving as txt)
- if you want to make your own simple audio reactive (of audio beats only for example) without multiple bands and all those bells and whistles just grab the Wavosaur
http://www.wavosaur.com/download.php (application as simple, as light and as easy to use as Anim8or) and I'll guide you through the simplified version of process
- until I'll release tool to substitute keyframes/scripts in Anim8or files with the lists I can process your list to create text that you can easily paste in your morphs' script controller
But DASSA LAAWNG RENDER TIME.
Nay... not very long to me. You'd probably render the same thing on your own computer in a fraction of time (a couple of hours only maybe?) considering most PCs around me are not very high end
Ooorrrr.. you can go for lower framerate like 15 FPS for example
I hope it sounds easier now and I'll encouraged you or someone else to experiment with this.
