I've waited all week to see any response to this posting, so in
desperation I figured I would mail it straight to some of the Sun
engineers. Can you please direct this to someone who can give me an
answer?
In short, if J3D doesn't use JavaSound, how does it play sound? With
native calls? How can I get J3D to play MP3 files? Can I convert MP3
to WAV on the fly and stream it to J3D to play?
My argument for MP3 is that Java is made to be usable across the net,
and use of long audio clips almost requires the use of MP3 because of
download size.
If not using MP3, can someone at Sun make another suggestion for playing
long audio clips (30sec to 1min)?
Thanks.

Subject: RE: [JAVA3D] Java3d, Java Sound, and MP3's
My teammate sent this question yesterday, but we haven't heard anything
back yet. The JavaDocs for the JavaSoundMixer (distributed in the Sun
J3D utils) says:
"The JavaSoundMixer Class defines an audio output device that accesses
JavaSound JavaSoundMixer functionality Hae stream data"
I'm not quite sure what that means, but it makes it sound like it uses
JavaSound to play sounds. We have tried an example MP3 player that
extends JavaSound using SPI, but we still get an exception as if the
sound mixer does not recognize the format.
Can we get some help from Sun on this? Has anybody had success with
playing anything other than the default filetypes (like MP3)?
BTW, why is the JavaSoundMixer part of the utils? It is a very large
piece of code, but we thought we might need to write our own. But this
code uses undocumented classes (j3d.audio.J3DHaeStream and others) to do
the actual work of playing the sample. How can I write my own if the
example code uses undocumented features of J3D???? And how can extend
the undocumented classes to use a different decoder??
(I have the feeling that these undocumented classes use native calls to
play sounds....)
