ngjackspa (JACK host for LADSPA plugins)
|
||||
|
||||
ngjackspa is a set of simple user interfaces that host a LADSPA plugin,
|
||||
providing JACK ports for its audio inputs and outputs, and dynamic setting
|
||||
of its control inputs. Additionally, the plugin controls can be exported
|
||||
to or controlled by control voltages on standard JACK audio ports.
|
||||
|
||||
By default, the Qt user interface is built, and the gtkmm UI is disabled.
|
||||
To disable Qt, set QT=no in the script's environment. To enable gtkmm,
|
||||
set GTKMM=yes (this will require gtkmm to be installed, of course).
|
||||
|
||||
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.

# 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.
