Cheers! robin PS. to get back on topic, http://www.jackaudio.org/files/docs/html/group__ServerControl.html#gad65c741a1d1d2fb09efacf51437b841a says "faster than realtime" execution of a JACK graph it can also be "slower than realtime", e.g live encode the jack-graph to .ogg and/or mp3 or multiple formats at the same time which can take considerable CPU. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
