.SH "DESCRIPTION" |
|
|
|
\fBjackd\fR is the JACK audio server daemon, a low\-latency audio |
|
|
|
server. Originally written for the |
|
|
|
GNU/Linux operating system, it also supports Mac OS X and various Unix |
|
|
|
platforms. JACK can connect a number of different client applications |
|
|
|
to an audio device and also to each other. Most clients are external, |
|
|
|
running in their own processes as normal applications. JACK also |
|
|
|
supports internal clients, which run within the \fBjackd\fR process |
|
|
|
using a loadable "plugin" interface. |
|
|
|
|
|
|
|
JACK differs from other audio servers in being designed from the |
|
|
|
ground up for professional audio work. It focuses on two key areas: |
|
|
|
synchronous execution of all clients, and low latency operation. |
|
|

|
\fB\-d, \-\-driver \fIbackend\fR [\fIbackend\-parameters\fR ] |
|
|
|
.br |
|
|
|
Select the audio interface backend. The current list of supported |
|
|
|
backends is: \fBalsa\fR, \fBcoreaudio\fR, \fBdummy\fR, \fBfreebob\fR, |
|
|
|
\fBoss\fR \fBsun\fR and \fBportaudio\fR. They are not all available |
|
|
|
on all platforms. All \fIbackend\-parameters\fR are optional. |

\fB\-h, \-\-help\fR |
|
|
|
.br |
|
|
|
Print a brief usage message describing the main \fBjackd\fR options. |
|
|
|
These do not include \fIbackend\-parameters\fR, which are listed using |
|
|
|
the \fB\-\-help\fR option for each specific backend. Examples below |
|
|
|
show how to list them. |
|
|
|
.TP |
|
|
|
\fB\-m, \-\-no\-mlock\fR |
|
|
|
Do not attempt to lock memory, even if \fB\-\-realtime\fR. |
|
|
|
.TP |
|
|
|
\fB\-n, \-\-name\fR \fIserver\-name\fR |
|
|
|
Name this \fBjackd\fR instance \fIserver\-name\fR. If unspecified, |
|
|
|
this name comes from the \fB$JACK_DEFAULT_SERVER\fR environment |
|
|
|
variable. It will be "default" if that is not defined. |
|
|
|
.TP |
|
|
|
\fB\-p, \-\-port\-max \fI n\fR |
|
|
|
Set the maximum number of ports the JACK server can manage. |
|
|
|
The default value is 256. |
|
|
|
.TP |
|
|
|
\fB\-\-replace-registry\fR |
|
|
|
.br |
|
|
|
Remove the shared memory registry used by all JACK server instances |
|
|
|
before startup. This should rarely be used, and is intended only |
|
|
|
for occasions when the structure of this registry changes in ways |
|
|
|
that are incompatible across JACK versions (which is rare). |
|
|
|
.TP |
|
|
|
\fB\-R, \-\-realtime\fR |
|
|
|
.br |
|
|
|
Use realtime scheduling (default = true). This is needed for reliable low\-latency |
|
|
|
performance. On many systems, it requires \fBjackd\fR to run with |
|
|
|
special scheduler and memory allocation privileges, which may be |
|
|
|
obtained in several ways. |
|
|
|
.TP |
|
|
|
\fB\-r, \-\-no-realtime\fR |
|
|
|
.br |
|
|
|
Do not use realtime scheduling. |
|
|
|
.TP |
|
|
|
\fB\-P, \-\-realtime\-priority \fIint\fR |
|
|
|
When running \fB\-\-realtime\fR, set the scheduler priority to |
|
|
|
\fIint\fR. |
|
|
|
.TP |
|
|
|
\fB\-\-silent\fR |
|
|
|
Silence any output during operation. |
|
|
|
.TP |
|
|
|
\fB\-T, \-\-temporary\fR |
|
|
|
Exit once all clients have closed their connections. |
|
|
|
.TP |
|
|
|
\fB\-t, \-\-timeout \fIint\fR |
|
|
|
.br |
|
|
|
Set client timeout limit in milliseconds. The default is 500 msec. |
|
|
|
In realtime mode the client timeout must be smaller than the watchdog timeout (5000 msec). |
|
|
|
.TP |
|
|
|
\fB\-Z, \-\-nozombies\fR |
|
|
|
.br |
|
|
|
Prevent JACK from ever kicking out clients because they were too slow. |
|
|
|
This cancels the effect any specified timeout value, but JACK and its clients are |
|
|
|
still subject to the supervision of the watchdog thread or its equivalent. |
|
|
|
.TP |
|
|
|
\fB\-u, \-\-unlock\fR |
|
|
|
.br |
|
|
|
Unlock libraries GTK+, QT, FLTK, Wine. |
|

\fB\-v, \-\-verbose\fR |
|
|
|
Give verbose output. |

Select a specific wall clock (Cycle Counter, HPET timer, System timer). |

\fB\-V, \-\-version\fR |
|
|
|
Print the current JACK version number and exit. |

.SS ALSA BACKEND OPTIONS |
|
|
|
.TP |
|
|
|
\fB\-C, \-\-capture\fR [ \fIname\fR ] |
|
|
|
Provide only capture ports, unless combined with \-D or \-P. Parameterally set |
|
|
|
capture device name. |
|
|
|
.TP |
|
|
|
\fB\-d, \-\-device \fIname\fR |
|
|
|
.br |
|
|
|
The ALSA pcm device \fIname\fR to use. If none is specified, JACK will |
|
|
|
use "hw:0", the first hardware card defined in \fB/etc/modules.conf\fR. |
|
|
|
.TP |
|
|
|
\fB\-z, \-\-dither [rectangular,triangular,shaped,none] |
|
|
|
Set dithering mode. If \fBnone\fR or unspecified, dithering is off. |
|
|
|
Only the first letter of the mode name is required. |
|
|
|
.TP |
|
|
|
\fB\-D, \-\-duplex\fR |
|
|
|
Provide both capture and playback ports. Defaults to on unless only one |
|
|
|
of \-P or \-C is specified. |
|
|
|
.TP |
|
|
|
\fB\-h, \-\-help\fR Print a brief usage message describing only the |
|
|
|
\fBalsa\fR backend parameters. |
|
|
|
.TP |
|
|
|
\fB\-M, \-\-hwmeter\fR |
|
|
|
.br |
|
|
|
Enable hardware metering for devices that support it. Otherwise, use |
|
|
|
software metering. |
|
|
|
.TP |
|
|
|
\fB\-H, \-\-hwmon\fR |
|
|
|
.br |
|
|
|
Enable hardware monitoring of capture ports. This is a method for |
|
|
|
obtaining "zero latency" monitoring of audio input. It requires |
|
|
|
support in hardware and from the underlying ALSA device driver. |
|
|
|
|
|
|
|
When enabled, requests to monitor capture ports will be satisfied by |
|
|
|
creating a direct signal path between audio interface input and output |
|
|
|
connectors, with no processing by the host computer at all. This |
|
|
|
offers the lowest possible latency for the monitored signal. |
|
|
|
|
|
|
|
Presently (March 2003), only the RME Hammerfall series and cards based |
|
|
|
on the ICE1712 chipset (M\-Audio Delta series, Terratec, and others) |
|
|
|
support \fB\-\-hwmon\fR. In the future, some consumer cards may also |
|
|
|
be supported by modifying their mixer settings. |
|
|
|
|
|
|
|
Without \fB\-\-hwmon\fR, port monitoring requires JACK to read audio |
|
|
|
into system memory, then copy it back out to the hardware again, |
|
|
|
imposing the basic JACK system latency determined by the |
|
|
|
\fB\-\-period\fR and \fB\-\-nperiods\fR parameters. |
|
|
|
.TP |
|
|
|
\fB\-i, \-\-inchannels \fIint\fR |
|
|
|
.br |
|
|
|
Number of capture channels. Default is maximum supported by hardware. |
|
|
|
.TP |
|
|
|
\fB\-n, \-\-nperiods \fIint\fR |
|
|
|
.br |
|
|
|
Specify the number of periods of playback latency. In seconds, this |
|
|
|
corresponds to \fB\-\-nperiods\fR times \fB\-\-period\fR divided by |
|
|
|
\fB\-\-rate\fR. The default is 2, the minimum allowable. For most |
|
|
|
devices, there is no need for any other value with the |
|
|
|
\fB\-\-realtime\fR option. Without realtime privileges or with boards |
|
|
|
providing unreliable interrupts (like ymfpci), a larger value may |
|
|
|
yield fewer xruns. This can also help if the system is not tuned for |
|
|
|
reliable realtime scheduling. |
|
|
|
|
|
|
|
For most ALSA devices, the hardware buffer has exactly |
|
|
|
\fB\-\-period\fR times \fB\-\-nperiods\fR frames. Some devices demand |
|
|
|
a larger buffer. If so, JACK will use the smallest possible buffer |
|
|
|
containing at least \fB\-\-nperiods\fR, but the playback latency does |
|
|
|
not increase. |
|
|
|
|
|
|
|
For USB audio devices it is recommended to use \fB\-n 3\fR. Firewire |
|
|
|
devices supported by FFADO (formerly Freebob) are configured with |
|
|
|
\fB\-n 3\fR by default. |
|
|
|
.TP |
|

|
|
|
.TP |
|
|
|
\fB\-P, \-\-playback\fR [ \fIname\fR ] |
|
|
|
Provide only playback ports, unless combined with \-D or \-C. Optionally set |
|
|
|
playback device name. |
|
|
|
.TP |
|
|
|
\fB\-p, \-\-period \fIint\fR |
|
|
|
.br |
|
|
|
Specify the number of frames between JACK \fBprocess()\fR calls. This |
|
|
|
value must be a power of 2, and the default is 1024. If you need low |
|
|
|
latency, set \fB\-p\fR as low as you can go without seeing xruns. A larger |
|
|
|
period size yields higher latency, but makes xruns less likely. The JACK |
|
|
|
capture latency in seconds is \fB\-\-period\fR divided by \fB\-\-rate\fR. |
|
|
|
.TP |
|
|
|
\fB\-r, \-\-rate \fIint\fR |
|
|
|
Specify the sample rate. The default is 48000. |

|
\fB\-S, \-\-shorts |
|
|
|
.br |
|
|
|
Try to configure card for 16\-bit samples first, only trying 32\-bits if |
|
|
|
unsuccessful. Default is to prefer 32\-bit samples. |
|
|
|
.TP |
|
|
|
\fB\-s, \-\-softmode\fR |
|
|
|
.br |
|
|
|
Ignore xruns reported by the ALSA driver. This makes JACK less likely |
|
|
|
to disconnect unresponsive ports when running without \fB\-\-realtime\fR. |
|
|
|
.TP |
|
|
|
\fB\-X, \-\-midi \fR[\fIseq\fR|\fIraw\fR] |
|
|
|
.br |
|
|
|
Specify which ALSA MIDI system to provide access to. Using \fBraw\fR |
|
|
|
will provide a set of JACK MIDI ports that correspond to each raw ALSA |
|
|
|
device on the machine. Using \fBseq\fR will provide a set of JACK MIDI |
|
|
|
ports that correspond to each ALSA "sequencer" client (which includes |
|
|
|
each hardware MIDI port on the machine). \fBraw\fR provides slightly |
|
|
|
better performance but does not permit JACK MIDI communication with |
|
|
|
software written to use the ALSA "sequencer" API. |

|
|
latency, set \fB\-p\fR as low as you can go without seeing xruns. A larger |

2. The period size (\fB\-p\fR) times \fB\-\-nperiods\fR times four |
|
|
|
(assuming 2 channels 16-bit samples) is the JACK buffer size in bytes. |

Run the JACK daemon with low latency giving verbose output, which can |
|
|
|
be helpful for trouble\-shooting system latency problems. A |
|
|
|
reasonably well\-tuned system with a good sound card and a |
|
|
|
low\-latency kernel can handle these values reliably. Some can do |
|
|
|
better. If you get xrun messages, try a larger buffer. Tuning a |
|
|
|
system for low latency can be challenging. The JACK FAQ, |
|

JACK is evolving a mechanism for automatically starting the server |
|
|
|
when needed. Any client started without a running JACK server will |
|
|
|
attempt to start one itself using the command line found in the first |
|
|
|
line of \fB$HOME/.jackdrc\fR if it exists, or \fB/etc/jackdrc\fR if it |
|
|
|
does not. If neither file exists, a built\-in default command will be |
|
|
|
used, including the \fB\-T\fR flag, which causes the server to shut |
|
|
|
down when all clients have exited. |
|
|
|
|
|
|
|
As a transition, this only happens when \fB$JACK_START_SERVER\fR is |
|
|
|
defined in the environment of the calling process. In the future this |
|
|
|
will become normal behavior. In either case, defining |
|
|
|
\fB$JACK_NO_START_SERVER\fR disables this feature. |
|
|
|
|
|
|
|
To change where JACK looks for the backend drivers, set |
|
|
|
\fB$JACK_DRIVER_DIR\fR. |
|
|
|
|
|
|
|
\fB$JACK_DEFAULT_SERVER\fR specifies the default server name. If not |
|
|
|
defined, the string "default" is used. If set in their respective |
|
|
|
environments, this affects \fBjackd\fR unless its \fB\-\-name\fR |
|
|
|
parameter is set, and all JACK clients unless they pass an explicit |
|
|
|
name to \fBjack_client_open()\fR. |
