Brian, John:
I went back and did some research. Here's how he said he did it to stream the audio:
"I imported your mp3 for Reflections (5 Mb) into Flash 5 and exported it as a
Flash swf (386 Kb). This ensures that the maximum audience will be able to hear
the music without running Java or using other less-supported plugins. The music
sounds great!
Sincerely,
Shamus"
Does that make sense?
If that is some other kind of compression codec, it did so with out degredation of the audio quality.
