7 This is a tabbed-dialog within the New Session dialog that will
8 appear only if JACK is <strong>not</strong> already running as you
9 start Ardour. It provides a simple interface to configure JACK, which
10 will then be started by Ardour. For more control and options regarding
11 JACK, it is recommended that you start JACK before using Ardour, via a
12 JACK control application such as qjackctl (sometimes called "Jack
13 Control"), JackPilot, etc.
18 <p> On this tab you can tell Ardour about the device it should use.
19 The driver setting will tell it what driver to attempt to
23 <dl class="wide-table">
27 On Mac OS X this will typically be CoreAudio. On Linux usually
28 this will be either FFADO or ALSA, depending on whether or not you are
29 utilizing a firewire device. Advanced users on all platforms may also
30 use NetJack which provides network audio I/O
35 The selector should show all the supported interfaces that the are duplex capable (i.e. support input and output to and from Ardour). <strong>Important</strong> if you are using an Intel Mac running
36 OS X and the built-in audio interface, you must
37 first <a href="/setting-up-your-system/using_more_than_one_audio_device">merge
38 its separate input and output devices into a single "aggregate
39 device"</a> before Ardour will be able to use it.
44 The selector will allow you to select from any sample rate
45 supported by the device selected above it.
50 You can adjust the size of the buffer used by your audio interface
51 to allow for either lower latency, or lower CPU usage and higher
58 This tab has a few options that should be rarely used by most
59 users. The Realtime Option allows Jack to run with Realtime
60 privileges, which allows for smoother audio. The Verbose Output
61 checkbox is primarily used for troubleshooting, it will cause Jack to
62 use verbose messaging and output it to the console. The client
63 timeout will help prevent clients from disconnecting from Jack if they
64 don't respond to Jack fast enough. The number of ports changes the
65 total number of ports that Jack will provide to all clients. And the
66 server dropdown will allow you to change the path to the Jack
67 executable to match where it is installed on your system.
72 The Advanced tab lets you to set some advanced settings that
73 are rarely needed. By default the input and output channels will
74 automatically try to give you the amount of inputs and outputs as
75 requested by the software, however some software doesn't always
76 request as many as you need. This option provides more channels to software that can handle it.
