+ This page is not displayed if <abbr title="JACK Audio Connection
+ Kit">JACK</abbr> is already running when you start
+ Ardour. It provides a simple interface to configure JACK, which
+ will then be started by Ardour. For more control and options regarding
+ JACK, it is recommended that you start JACK before using Ardour, via a
+ JACK control application such as QJackCtl (sometimes called "Jack
+ Control"), JackPilot, etc.

+ <dt>Audio System</dt>
+ <dd>Currently, the only option here is <kbd class="menu">JACK</kbd>. In the future, native
+ hardware access may be supported.</dd>
+ <dt>Driver</dt>
+ <dd>
+ On Mac OS X this will typically be <kbd class="menu">CoreAudio</kbd>. On Linux usually
+ this will be either <kbd class="menu"><abbr title="Free Firewire Audio Driver fOr
+ linux">FFADO</abbr></kbd>
+ or <kbd class="menu"><abbr title="Advanced Linux Sound
+ Architecture">ALSA</abbr></kbd>, depending on whether or not you are
+ utilizing a firewire device. Advanced users on all platforms may also
+ use <kbd class="menu">NetJack</kbd> which provides network audio I/O.
+ </dd>
+ <dt>Device</dt>
+ <dd>The selector should show all availiable interfaces provided by the
+ driver above and which are capable of duplex operation.
+ <p class="warning">
+ If you are using an Intel Mac
+ running OS X and the builtin audio interface, you must
+ first <a href="setting-up-your-system/us
+ ing_more_than_one_audio_device/">merge its separate input and
+ output devices into a single "aggregate device"</a> before
+ Ardour will be able to use it.
+ <p>
+ </dd>
+ <dt>Sample Rate</dt>
+ <dd>
+ The selector will allow you to select from any sample rate
+ supported by the device selected above it.
+ </dd>
+ <dt>Buffer Size</dt>
+ <dd>
+ You can adjust the size of the buffer used by your audio interface
+ to allow for either lower latency, or lower CPU usage and higher
+ latency.
+ </dd>
+ <dt>Input/Output Channels</dt>
+ <dd>
+ Here you can specify the number of hardware channels to use. The
+ default is <kbd class="menu">all available channels</kbd>.</dd>
+ <dt>Hardware Input/Output Latency</dt>
+ <dd>Specify the hardware delay in samples for precise latency compensation.</dd>
+ <dt>Calibrate</dt>
+ <dd>
+ This button guides you through a semi-automated process to obtain
+ precise hardware latency measurements for the above option.</dd>
+ <dt>MIDI System</dt>
+ <dd>
+ Select the MIDI driver to use. On Mac OS X, this will be <kbd
+ class="menu">CoreMIDI</kbd>. On Linux, you can change between two legacy
+ ALSA drivers or the (preferred) new JACK+ALSA implementation.</dd>
