-**A:​** ​<​del>​Using ​"​real-time ​kernel" and setting priorities appropriate is an important step here</​del>​. This has often been told, but according to the jackd FAQ it is simply not true! See [[http://​jackaudio.org/​realtime_vs_realtime_kernel]] +**A:​** ​For some uses, it can be helpful to run realtime (RT) kernel, but generally this isn't necessary anymore. See the following JACK FAQ entry: ​[[http://​jackaudio.org/faq/​realtime_vs_realtime_kernel.html Do I need a realtime kernel to use realtime scheduling?]]
-[[wiki:​real_time_info|Articles and more information about real time operation]].+
  
 +In Linux kernels 3.0 and later, many of the additionally required realtime patches have been incorporated as standard. For those who are recording Audio, a standard non-realtime kernel may be sufficient for your needs, and running Jack with a non realtime kernel will work fine.

The standard frequency ​is set at 250 Hz, and realtime kernels are generally set at 1000 Hz. You may still have to use a realtime kernel to obtain accurate ​MIDI playback using the higher timing setting.

 +==== Q: How to eliminate noise from live production? ====
 +Live noise has many causes, including ground-loops,​ and other equipment near and far injecting static of many kinds. ​ This includes including weak but audio-active USB signals, PC fan noise, firewire, et cetera, into powerline, ground, and thence into the system. ​ There are many approaches to this, and often more than one approach is needed.
