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....)
