I have been wondering about this for some time. I have never really thought
that Java could do real-time audio through direct programming at low level.
What we really need are additions to the Java spec, to include low-level
audio primitives and output streaming facilities, to say nothing of support for
CD-quality audio files. I have heard vague rumours about such a possibility,
but nothing definite. Any concrete information on this would be of great
interest.
Needless to say, Microsoft plug-ins are not the answer...

JavaSoft has licenced the software synthesis engine from HeadSpace for
inclusion in a future version of Java. Try http://www.headspace.com for
information on the technology. See http://www.javasoft.com for release dates,
etc. As far as CD-quality audio support and streaming, see the Java Media
Framework spec at http://www.javasoft.com/products/java-media/jmf/index.html. I
think Intel and SGI have JMF players you can use now.

Sun has licensed the Headspace audio engine for use in Java. You can get
press release info from the Headspace web site at www.headspace.com.
I'm not sure about streaming, but it allows for multiple CD quality
audio file playback, and softsynth MIDI.

yes the Headspace audio engine has been licensed to Sun Microsystems for
inclusion in the Java spec (you should see some of this show up in the
JDK1.2)...Beatnik (the environment around the HAE) is basically a wavetable
(sample playback) software synth that comforms to the GM MIDI spec but has
provision to add custom samples and export them (plus MIDI file) in an RMF
file format...this RMF wrapper can be thought of as MOD++ as it allows 40
bit encryption, file compression and watermarking for copyright
purposes...the Beatnik sound set was developed in house (partly by me) and
vastly exceeds any other GM soundset on the market in terms of aesthetic
quality (ie: its very adept at creating good electronic music ala techno,
drum and bass, ambient etc)...but since you can import custom samples you're
not limited by what we think a good soundbank should contain...I've been
creating some samples in Csound (and Virtual Waves) and importing them into
Beatnik for an Auditory Display project I'm working on for
Headspace...additionally there is a javascript function library for the
Netscape plugin that allows programmers to implement a good degree of
interactivity (ie: onClick, mouseOver, onLoad etc)...
what Beatnik doesn't do at this time: stream audio, do any flavor of sound
synthesis (except for wavetable of course), algorithmic composition or have
any API for TCP/IP ie: for online jamming...
Java has potential even though the VM's are still 30% slower than
C/C++...the JIT compilers hold some promise although are still 3 -5 times
slower than C/C++...an improvement but still not fast enough for realtime DSP...
one technology that I personally feel offers alot of promise is the
Structured Audio Orchestra Language being developed at
MIT......it presently has a syntax
akin to C but I'm hoping that it takes on more of an OO syntax and/or drops
the orc/sco model...people using Csound should look to this technology since
it will most likely be incorporated into the MPEG-4 spec...the SAOL spec is
online at the URL above please DL it, read it and offer feedback...
there are alot of people doing very interesting work for audio on the net
but unless it incorporates some TCP/IP capability via Java I think we're
still dealing with an old model (closed system)...HAE and SAOL hold alot of
promise for the future of web audio...
just my .02

Hello all,
Now a new version of Win95 MIDI Csound is avalible. The additions are:
Release 1.73 additions (11/6/97)
----------------------
1) New MIDI IN controller UGs. The same as midicXX opcodes but now
they can be activated by a score i statement without Csound crashes.
These UGs are : ictrl7, ctrl7, ictrl14, ctrl14, ictrl21, ctrl21.
A new argument allows the user to define the MIDI channel apart
from the instrument number.
2) Initialization of controllers now can be set to any value (it can
different from the minimum value set in midicXX and ctrlXX.
Opcodes initc7, initc14, initc21).
Release 1.72 additions
----------------------
1) Command line can now be included in a file ('-/' flag). Very
useful using Win95 long names, when command line is more long
than 138 characters allowed by DOS.
2) ftlen2() function now can return non-power-of-two length of
deferred tables created with GEN1.
3) John Fitch's FOG fixing included.
Also sources of the new opcodes are avalaible.
You can download executable and new UGs sources at the following url:
http://www.agora.stm.it/G.Maldonado/download.htm
or at the geocities site (mirror):

bye and happy csounding :)
