Realtime Audio Workstation on Slackware

Slackware hasn't got a dependency system. here is the schematic of what you'll need to build a full Audio Workstation with Slackware

• Ardour2 Multitrack mixer/editor http://www.ardour.org

• Jamin Stereo Mastering Processor http://jamin.sourceforge.net/

• Audacity Stereo Recorder/Editor http://audacity.sourceforge.net

[This is also valuable information if you just want to build yourself from latest sources a complete Ardour stack on any machine.] For the Realtime kernel part, please check them here: http://rt.wiki.kernel.org/index.php/Main_Page http://www.kernel.org/pub/linux/kernel/projects/rt/

(Don't expect your proprietary nVidia graphic drivers to work with them tough)

Dependency in discovery order

(see below for Build Order)

• Ardour http://slackbuilds.org/repository/13.0/audio/ardour/
• Jamin http://slackbuilds.org/repository/13.0/audio/jamin/
• audacity http://slackbuilds.org/repository/13.0/audio/audacity/

they, in turn, require lot more of course.

• • liblo http://slackbuilds.org/repository/13.0/libraries/liblo/

• • wxPython http://slackbuilds.org/repository/13.0/libraries/wxPython/

• • liblrdf http://slackbuilds.org/repository/13.0/libraries/liblrdf/
    • ladspa_sdk http://slackbuilds.org/repository/13.0/audio/ladspa_sdk/

• • scons http://slackbuilds.org/repository/13.0/development/scons/
    • python (by default on Slackware machines)

• • fftw http://slackbuilds.org/repository/13.0/libraries/fftw/

• • libsamplerate http://slackbuilds.org/repository/13.0/libraries/libsamplerate/

• • libgnomecanvas http://slackbuilds.org/repository/13.0/libraries/libgnomecanvas/

• • twolame http://slackbuilds.org/repository/13.0/audio/twolame/

• • soundtouch http://slackbuilds.org/repository/13.0/libraries/soundtouch/
    • libsndfile http://slackbuilds.org/repository/13.0/libraries/libsndfile/

• • jack-audio-connection-kit http://slackbuilds.org/repository/13.0/audio/jack-audio-connection-kit/
    • libsndfile

    • libsndfile
    • libsamplerate
    • fftw

• • slv2 http://slackbuilds.org/repository/13.0/libraries/slv2/
    • lv2core http://slackbuilds.org/repository/13.0/audio/lv2core/

You may need also, depending on your hardware and formats requirements:

• • alsa-plugins http://slackbuilds.org/repository/13.0/audio/alsa-plugins/
    • jack-audio-connection-kit
    • libsamplerate
    • pulseaudio http://slackbuilds.org/repository/13.0/audio/pulseaudio/
      • libatomic_ops http://slackbuilds.org/repository/13.0/libraries/libatomic_ops/
      • libsamplerate
      • libsndfile
      • jack-audio-connection-kit

and:

• • • • ffmpeg http://slackbuilds.org/repository/13.0/multimedia/ffmpeg/

notes

Pulseaudio will need a pulse group/user to run. You can add one with
# groupadd -g 214 pulse
# useradd -u 214 -g pulse -d /var/lib/pulse pulse
or something similar. See http://slackbuilds.org/uid_gid.txt

jackd has to run with realtime priviledges. One way to do this on Slackware would
be to use set_rlimits. Since 12.2 there's another way, though experimental. If
you have a filesystem that supports posix capabilities (reiserfs does not), you
can grant jackd the rights to run in realtime mode, even when started as normal user
with the following command: setcap cap_ipc_lock,cap_sys_nice=ep /usr/bin/jackd

(Merely suggested; it'll do no good to either of us if you drag me in front of a court on that)

(Of course, you could just use http://www.ubuntustudio.com which has everything, including an excellent RT kernel working out of the box.)
