This is a tabbed-dialog within the New Session dialog that will
|
|
appear only if JACK is <strong>not</strong> already running as 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.

<h3>Device Tab</h3>
|
|
|
|
<p> On this tab you can tell Ardour about the device it should use.
|
|
The driver setting will tell it what driver to attempt to
|
|
access.
|
|
</p>

<dl class="wide-table">

|
|
|
<dt>Driver</dt>
|
|
<dd>
|
|
On Mac OS X this will typically be CoreAudio. On Linux usually
|
|
this will be either FFADO or ALSA, depending on whether or not you are
|
|
utilizing a firewire device. Advanced users on all platforms may also
|
|
use NetJack which provides network audio I/O
|
|
</dd>
|
|
|
|
<dt>Interface</dt>
|
|
<dd>The selector should show all availiable interfaces that driver
|
|
provides that are duplex capable for Ardour to
|
|
use. <strong>Important</strong> 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.
|
|
</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.

<h3>Options Tab</h3>
|
|
<p>
|
|
This tab has a few options that should be rarely used by most
|
|
users. The Realtime Option allows Jack to run with Realtime
|
|
privileges, which allows for smoother audio. The Verbose Output
|
|
checkbox is primarily used for troubleshooting, it will cause Jack to
|
|
use verbose messaging and output it to the console. The client
|
|
timeout will help prevent clients from disconnecting from Jack if they
|
|
don't respond to Jack fast enough. The number of ports changes the
|
|
total number of ports that Jack will provide to all clients. And the
|
|
server dropdown will allow you to change the path to the Jack
|
|
executable to match where it is installed on your system.
|
|
</p>
|

|
|
<h3>Advanced Tab</h3>
|
|
<p>
|
|
The Advanced tab lets you to set some advanced settings that
|
|
are rarely needed. By default the input and output channels will
|
|
automatically try to give you the amount of inputs and outputs as
|
|
requested by the software, however some software doesn't always
|
|
request as many as you need. This option provides more channels to software that can handle it.
