jack (realtime low-latency sound server)
|
||||
|
||||
JACK is a system for handling real-time, low latency audio and MIDI.
|
||||
It can connect a number of different applications to an audio device,
|
||||
as well as allowing them to share audio between themselves.
|
||||
|
||||
Its clients can run in their own processes (ie. as normal apps), or
|
||||
within the JACK server (ie. as a "plugin"). JACK also has support for
|
||||
distributing audio processing across a network, both fast & reliable
|
||||
LANs as well as slower, less reliable WANs.
|
||||
|
||||
Note: This build conflicts with jack1: install only one of the two.
|
||||
JACK's developers recommend not using jack1 at all, although it's still
|
||||
maintained.
|
||||
|
||||
Note: this build was formerly known as jack2. Before installing this,
|
||||
"removepkg jack2" if you had it installed.
|
||||
|
||||
SBo build maintainers, please list jack (not jack1) as a dependency for
|
||||
your builds. If the software you're trying to build really does work
|
||||
with jack1 but not jack, please contact the jack maintainer (currently
|
||||
B. Watson <yalhcru@gmail.com>. Include the build log and any runtime
|
||||
error messages in your email, plase.
|
||||
|
||||
This package uses POSIX filesystem capabilities to execute with
|
||||
elevated privileges (required for realtime audio processing). This
|
||||
may be considered a security/stability risk. Please read
|
||||
http://www.slackbuilds.org/caps/ for more information. To disable
|
||||
capabilities, pass SETCAP=no to the script.
|
||||
|
||||
Optional dependencies are celt, libffado and opus.

20200119 bkw: The default jack version on SlackBuilds.org is now 1.9.14,
|
||||
aka JACK2. The old 0.125.0 version (formerly jack-audio-connection-kit)
|
||||
is still available as "jack1". The JACK2 build used to be called "jack2",
|
||||
and has been renamed to simply "jack". SBo maintainers take note: please
|
||||
don't list jack1 in REQUIRES for your builds. If your build really does
|
||||
work only with jack1 and fails with jack, please contact me (B. Watson,
|
||||
yalhcru@gmail.com) and let me know the details.
|
||||
|
||||
This information might be helpful in understanding the differences
|
||||
between jack and jack1.
|
||||
|
||||
jack and jack1 are API compatible enough that applications can be built
|
||||
against either, and in fact most (possibly all?) apps can be built
|
||||
against one and run with the other with no problems.
|
||||
|
||||
jack1 wasn't designed to benefit from multiple CPU cores/threads. It may
|
||||
(or may not) offer slightly better performance on single-core systems.
|
||||
|
||||
jack no longer supports jack1's "-Z" flag.
|
||||
|
||||
When using -Xseq with jack, connect your ALSA MIDI devices to the system
|
||||
"MIDI thru" port, then connect that port to the JACK midi capture
|
||||
port. This is an extra step that isn't necessary with jack1.
|
||||
|
||||
jack stores a persistent "registry" and database in /dev/shm, which
|
||||
is intended to speed up jack startup and allow multiple jack servers
|
||||
on the same host to cooperate. There is one small issue with this:
|
||||
if jackd can't write to /dev/shm/jack_db/, it will fail to start
|
||||
(segfault). If this happens, make sure jackd is not running, and "rm
|
||||
-rf /dev/shm/jack*". This only happens when jackd is used by different
|
||||
users, which means most of us will be unaffected by it. Upstream has
|
||||
been notified, and a fix is being worked on.
|
||||
|
||||
Original README from the old jack2 package has some possibly outdated
|
||||
info on the differences between 1 and 2:
|
||||
|
||||
jackdmp (aka JACK2) is a C++ version of the JACK low-latency audio
|
||||
server for multi-processor machines. It is a new implementation
|
||||
of the JACK server core features that aims in removing some
|
||||
limitations of the JACK1 design. The activation system has been
|
||||
changed for a data flow model and lock-free programming techniques
|
||||
for graph access have been used to have a more dynamic and
|
||||
robust system.
|
||||
|
||||
- jackdmp use a new client activation model that allows simultaneous
|
||||
client execution (on a smp machine) when parallel clients exist
|
||||
in the graph (client that have the same inputs). This activation model
|
||||
allows to better use available CPU on a smp machine, but also works
|
||||
on a mono-processor machine.
|
||||
|
||||
- jackdmp use a lock-free way to access (read/write) the client graph,
|
||||
thus allowing connections/disconnection to be done without
|
||||
interrupting the audio stream. The result is that
|
||||
connections/disconnections are glitch-free.
|
||||
|
||||
- jackdmp can work in 2 different modes at the server level :
|
||||
- synchronous activation : in a given cycle, the server waits for
|
||||
all clients to be finished (similar to normal jackd)
|
||||
- asynchronous activation : in a given cycle, the server does not
|
||||
wait for all clients to be finished and use output buffer
|
||||
computed the previous cycle.
|
||||
|
||||
The audible result of this mode is that if a client is not activated
|
||||
during one cycle, other clients may still run and the resulting audio
|
||||
stream will still be produced (even if its partial in some way).
|
||||
This mode usually result in fewer (less audible) audio glitches in a
|
||||
loaded system.

# HOW TO EDIT THIS FILE:
|

# The "handy ruler" below makes it easier to edit a package description.
|
||||
# Line up the first '|' above the ':' following the base package name, and
|
||||
# the '|' on the right side marks the last column you can put a character in.
|
||||
# You must make exactly 11 lines for the formatting to be correct. It's also
|
||||
# customary to leave one space after the ':' except on otherwise blank lines.
