In Ireland today, ‘the Jacks' is still a term used to describe a toilet. Following Jack's sudden departure from his home country, another common phrase was also coined by people that knew him, simply put: ‘You don't know Jack Shit'. Well, now thanks to WWN's ceaseless passion for journalism, you do. Now you know Jack Shit. Jack as a boys' name is pronounced jak. It is of Old English and Hebrew origin, and the meaning of Jack is 'God is gracious; he who supplants'. Name based on John (Hebrew), or Jacques, the French form of Jacob (Hebrew). The name has a rugged, down-to-earth aura. Jackie is used more for girls than for boys. Actors Jackie Gleason, Jack Nicholson, Jack Black; comedian Jack Benny; exercise guru Jack LaLanne.
The term 'JACK' is mentioned often in context without actually discussing it in detail and it is difficult to understand JACK's depth and importance within other discussions. This page hopes to alleviate this situation.
Simply stated, JACK is a recursive acronym for JACK Audio Connection Kit which is a sound server (and more!) that will serve audio to applications that request it. But merely calling JACK a 'sound server' belies its other powerful, pervasive aspects and capabilities.
Gsn games app. Indeed, JACK provides the audio backbone for Linux audio and all serious audio distributions not only include it, but have come to rely on it.
Connectivity
But JACK will not only serve sound in a unilateral direction, it also allows interconnection of audio and midi between 'JACK-aware' applications. For example, this means that you can take sound from an application, route it into a second application and then route it back into the first application. Thankfully, there are many 'JACK-aware' applications, and the list is growing.
It is also worth noting that some applications rely on JACK and will not start unless JACK is already running.
Low Latency
Since JACK was developed for professional audio work it makes all these connection with extremely low latency (the time between when I sound is created and when it is heard). This is critical for serious audio work because it can become impossible to properly sync or multi-track audio if the latency is too great. The ability to leverage the real-time kernel also facilitates achieving lower latencies.
Transport Control
Additionally, an often overlooked (or unmentioned) feature of JACK is to act as a transport control. This function allows one applications to be designated as a master transport that will control the starting and stopping of other applications. For example, if Ardour is set as the transport master, starting Ardour will also start the Hydrogen drum machine.
Audio Backends
Various audio back ends are available for JACK to use including:
- ALSA
PortAudio
CoreAudio
- FreeBOB
- FFADO
- OSS
JACK over the Net
Lastly, JACK can also send data over a network or internet via NetJack. Although this requires JACK to be built against the CELT codec.
Starting JACK
To use JACK we must start jackd, the jack daemon (background process). This can be effect with the Command Line Interface (CLI) or using a graphical user interface (GUI), in this case qjackctl.
Note, jackd should not be confused with jack, which is a cd ripper and encoder application.
CLI
jackd can be started from the CLI in a rather succinct manner which also establishes the configuration at the same time. An example is:
See the Ubuntu jackd manpage for a list of the expansive options.
Despite the large amount of options, it can be very easy to start JACK from the CLI with the correct options and is regularly started in this manner, although it is possible that most users will want to use a GUI.
qjackctl
A GUI is available to start the jackd daemon, which makes using JACK more accessible especially to newer users. The interface can be seen below:
qjackctl is fairly comprehensive and not only provides access to the start and transport controls, but also provides immediate access to the Connect (connection) and Setup (configuration) buttons.

For more information about starting and using JACK via qjackctl see the JackQuickStart page.
Configuring JACK
JACK configuration can be accessed in qjackctl by selecting the Setup key. This provides a graphical dialogue box for editing various JACK options. Digital art software free.
This has several benefits over starting JACK with options from the CLI, including the ability to save and recall option settings by name and showing the latency for the current option settings.

Connections via JACK
Making connections via JACK can be effected in qjackctl by selecting the Connect key. This provides a graphical dialogue box for making audio and midi connections with JACK.
