For playing ogg files, you need at least Java 1.3 (including
the javax packages for direct audio access). As I have learned,
the new (IBM) 1.3 java virtual machines (with JIT switched on)
do a very good job. Forget the times, when JAVA programs
run at a speed at least a magnitude below machine dependent
plus compiled (e.g. C) programs! For example the JAVA ogg player
(44.1 kHz sampling rate, stereo, 128k) needs approx. 30%
cpu load on my Pentium II 400. The speedup from JAVA 1.1.8
to JAVA 1.3 is 4...5! For example sounds, see my home
page www.jbergmann.de (in german).
