I believe there are many C++ implementations of JACK API, but I'll add my 50 cents to the game anyway. I created this for my own applications, and this is very new and untested piece of code. Anyway, I welcome any comments on this and hopefully this code could be useful to someone else too. A basic JACK application made using this library works OK anyway. Current implementation is available from: http://www.sonarnerd.net/linux/libjackmm-071104.tar.gz -- Jussi Laako <jussi.laako(a)pp.inet.fi>
