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 availiable interfaces that driver
36 provides that are duplex capable for Ardour to
37 use. <strong>Important</strong> if you are using an Intel Mac running
38 OS X and the builtin audio interface, you must
39 first <a href="/setting-up-your-system/using_more_than_one_audio_device">merge
40 its separate input and output devices into a single "aggregate
41 device"</a> before Ardour will be able to use it.
46 The selector will allow you to select from any sample rate
47 supported by the device selected above it.
52 You can adjust the size of the buffer used by your audio interface
53 to allow for either lower latency, or lower CPU usage and higher
60 This tab has a few options that should be rarely used by most
61 users. The Realtime Option allows Jack to run with Realtime
62 privileges, which allows for smoother audio. The Verbose Output
63 checkbox is primarily used for troubleshooting, it will cause Jack to
64 use verbose messaging and output it to the console. The client
65 timeout will help prevent clients from disconnecting from Jack if they
66 don't respond to Jack fast enough. The number of ports changes the
67 total number of ports that Jack will provide to all clients. And the
68 server dropdown will allow you to change the path to the Jack
69 executable to match where it is installed on your system.
74 The Advanced tab will allow you to set some advanced settings that
75 are rarely needed. By default the input and output channels will
76 automatically try to give you the amount of inputs and outputs as
77 requested by the software, however some software doesn't always
78 request as many as you need, this can provide more to software that
