Add a method like "long getTimeInMicroseconds()" to AudioSystem, or a small class "HighResClock" or similar. This is important functionality for many multimedia applications, especially those handling MIDI.

N/A

	Any application using sound features that needs to provide long-time stability (i.e. conferencing systems, games, music software) needs to have a stable clock source to synchronize different types of media.

	Tiger will feature the method System.nanoTime() as part of the concurrency API (JSR-166). Therefore, with consent of the Java Sound working group, I close this as duplicate of 4486658.

This is a very important bug, mainly for making JavaSound truly cross-platform. As is today it cannot be 
relied on to work correctly in Windows which for me makes Java unusable for the project I'm involved in. 
That's too bad since I like Java a lot!

My workaround is a JNI call to a microsoft timer call. Yuck, Phleeaachh!

This would make JavaSound usefull.

Project XEMO, a music and audio environment built on the 
NetBeans platform will require this feature for the 
development of their performance API... see www.xemo.org 
for more details

Has anyone looked into this IBM project that may be of use here?

jni -> native library getTime() function

hi i am working for some test of precise science  program.i
need a high acurate to microsecond timer too.hope sun micro
can add the new feature in the 1.5 tiger.

I'm a communication research technician at the Annenberg
School for Communication. We've just begun some pyschophy s
experiments using a DOS-based application called VPM that
records the physiological data coming from human
participants like heart rate, skin conductance, other EMG
reading, etc. The program can only run in DOS, because it's
system clock allows millisecond precision, whereas the
Windows clock does not - which seems pretty ironic. I want
to be able to develop a millisecond timer in Jave that can
be up to 10 milliseconds +/- in recording human response. I
want Sun Microsystems to create a timer package that
everyone on earth can use to this end sotha we don't have to
keep using a DOS-based application.
