-- oops, the first one was sent as a reply, here's the whole thing as a new thread. frustrated by the poor implementation of the jack bindings for python (pyjack), i wrote my own in native python using ctypes. the first test client mixed a 440hz sine wave using native python lists, and the cpu usage was about ~11%. i reimplemented the sine generator with numerics, and got it down to ~2%. i believe that considering the overhead of the python implementation, that result isn't too bad, and maybe allows for more than just prototyping. i attached the jack wrapper with the test client contained for those who are interested. its not entirely wrapped and lacks some functionality. -- -- leonard "paniq" ritter -- http://www.mjoo.org -- http://www.paniq.org
