Hi All, JAudioLibs v1.0.120123 is now available from http://code.google.com/p/java-audio-utils There's only one major change in this release - the addition of JNAJack support for JNA's new CallbackThreadInitializer, which was specifically requested for JNAJack, and brings a big improvement in CPU usage. Use of JNA 3.4.0+ is now highly recommended, and JNAJack will emit a warning if an earlier version of JNA is detected (though it will still work). There are no API changes. Full release notes are available at http://code.google.com/p/java-audio-utils/wiki/ReleaseNotes As you may have guessed from the version number, this is actually the code from the January release of Praxis (http://code.google.com/p/praxis/). The delay in releasing separately was caused by a) the desire to test and b) a manic couple of months! ;-) Best wishes, Neil -- Neil C Smith Artist : Technologist : Adviser http://neilcsmith.net
