Jack - Audio Connection Kit NOTES Jack is a versatile, high-performance sound server. It is geared towards music professionals, and offers excellent low-latency operation when properly configured. Jack works best with, but does not require, a low-latency patched kernel. To obtain a patch for your kernel, see: http://members.optusnet.com.au/ckolivas/kernel If you are using a patched kernel and wish to run jackd as a non-priviliged user, consider launching the jack daemon with: schedtool -I -e jackd [options] This will allow jackd to run in near real-time, to provide minimum latency, without starving other processes.
