Minim - 3D Spectrum Demo (and issue)
Dec 30th, 2008, 6:04pm  
Minim seems really easy to use:
The following is a demo 3d spectrum based on a popular rap tune.

http://www.ivanlazarte.com/processing/mos/spectrum_3d/applet/index.html

The issue I'm having that the mp3 file is simply too large!  

Given that the bulk of the data is not a Java class, is there some way I can make a preloader in Processing while the mp3 is being downloaded?  
My instinct says create a new Thread, and charge it with downloading the mp3 track, and the main draw() function simply checks to see if a isFinished download flag is set to true.

Thoughts?  I'm not familar with awts threading model so it's a little unclear how to proceed.  If this is solved in a clear manner, all sorts of goodies could be preloaded this way...

Are you loading the mp3 file entirely into memory, or streaming it? i.e. AudioPlayer or AudioSnippet?

Actually, just looked at the code, I see you are using an AudioPlayer, which is good. I'm not sure why it's taking so long to start playing. I shouldn't think the applet would actually download the entire mp3 file to a user's computer before streaming it, but it might.

hmm, it just occurred to me to try to reference an http location http://myhost/mp3/song.mp3.   but then that would trigger security exceptions right?  i'll give that a go later...
