SiSco.lv2 a Simple Oscilloscope LV2 plugin for scientific measurements.
source: https://github.com/x42/sisco.lv2
manual: http://x42.github.io/sisco.lv2/
I recently had a need for a proper software-oscilloscope and there was
also the the case about providing a LV2 example to transfer Arrays of
LV2-Atoms. The latter is now available as eg05-scope.lv2 from lv2plug.in
"Gentlemen, when two separate events occur simultaneously pertaining to
the same object of inquiry, we must always pay strict attention."
(Dale Cooper)
SiSco is not a waveform display but an audio scope which accurately
reproduces the signal up to a maximum resolution of about 1μs/pixel
@48KSPS (corresponding to 960KHz resolution) to facilitate
measurements of an audio stream.
While it may seem advanced, it is still rather simple compared to
current technology hardware oscilloscopes:
* 1-4 channels
* grid-resolution min: 50μs, max: 1 sec (max buffer time 15 sec)
* per channel horizontal & vertical offset and amplitude scaling
* automatic and manual trigger with optional hold-off
* two time-axis cursors (shared among channels)
* numeric readout (RMS, P-P, dt) per channel
* display memory (freeze display - not acquisition - of any channel)
It is already available on various GNU/Linux distributions (although
maybe not yet the latest version) as part of the "x42-plugin" bundle.
Cheers!

Apologies for x-posting...
It is my pleasure to announce tonight's premiere of OPERAcraft. Hosted
by Virginia Tech's Institute for Creativity, Arts, and Technology, in
collaboration with the School of Performing Arts (SOPA), and Linux
Laptop Orchestra (L2Ork), this week will feature a premiere and a second
performance of a newly produced opera. While both events are sold out,
they will be also streamed live online (please see below for a link and
additional info).
OPERAcraft couples traditional opera with a custom mod of ubiquitous
Minecraft designed at Virginia Tech specially for this purpose. Using
Linux Laptop Orchestra's pd-l2ork software Minecraft's custom mod is
transformed into a full-fledged staging environment, with animated
character mouth movement driven through pd-l2ork's speech analysis
engine, hand and body gestures, multiple camera angles, camera view
mixer, subtitles, behind-the-scenes performer warnings, and a full scene
control (fadeouts, transitions, etc.).
A 20-minute opera titled "The Surface: a world above" is desiged by and
large by high school students, including story, libretto, costume and
set design. The project is directed by Prof. Ariana Wyatt, Virginia Tech
School of Performing Arts' voice faculty. The music is an adaptation of
Mozart's arias performed by Virginia Tech School of Performing Arts'
piano faculty Dr. Tracy Cowden. Operacraft mod and supporting pd-l2ork
infrastructure was imagined and designed by Virginia Tech School of
Performing Arts' and ICAT computer music faculty Dr. Ivica Ico Bukvic
and devised in collaboration with Virginia Tech Computer Science
undergraduate student Cody Cahoon.

KXStudio 12.04.3 RELEASE ANNOUNCEMENT
KXStudio is a freely downloadable and easy to use GNU/Linux operating
system that focuses on audio and video production. The installation disc
includes a comprehensive selection of ready-to-run multimedia production
software such as the Ardour, qtractor and REAPER DAWs, the KDEnlive video
editor, the Renoise, Sunvox and Rosegarden sequencers, GIMP image editor,
k3b CD/DVD/BD burner, 100's of effect plugins and virtual instrument
plugins and much, much more. KXStudio allows everybody to hit the ground
running with an optimized and largely pre-configured free software based
digital studio.
Multimedia-focused GNU/Linux distributions are nothing new, so what makes
KXStudio special?
* KXStudio includes Cadence, a suite of custom tools that makes it simple
to manage the various layers and features of the various Linux audio
sub-systems, integrating them seamlessly via a single app. If you've
attempted audio production under Linux previously and struggled, you may
find Cadence to be the solution to your Linux audio difficulties.
* The easiest way to get going with KXStudio is to install afresh from its
DVD ISO but more experienced Linux users have the option of adding the
KXStudio software repositories onto an existing Ubuntu or Debian
installation so that they may easily install a wide variety of multimedia
packages and just take what they need. This allows for many more
installation and customization options compared to other Linux
distributions and puts the proprietary operating systems to shame in
comparison.
* GNU/Linux audio plus its installation and configuration is no longer
shrouded in mystery thanks to the concise and easy to read KXStudio
documentation available at http://wiki.linuxaudio.org/wiki/kxstudio_manual
If you'd like to be creative with your computer and free of the demands and
limitations of the corporately controlled alternatives, KXStudio is
arguably the best option available!

On behalf of the entire Rivendell development team, I'm pleased to announce the availability of Rivendell v2.5.5. Rivendell is a full-featured radio automation system targeted for use in professional broadcast environments. It is available under the GNU General Public License.
From the NEWS file:
*** snip snip ***
If upgrading from a v1.x version of Rivendell, be sure to read the
'UPGRADING' file before proceeding for important information.
Changes:
RLM API Extension. Added new fields to the 'rlm_pad' struct to
allow plug-ins to determine actual and predicted start times for events.
RDMonitor Enhancements. Extended RDMonitor to allow proper positioning
on multi-head displays.
LiveWire Switcher Driver Changes. The switcher drivers for LiveWire
have been refactored into three separate drivers:
LWRP Audio - Allows switching of audio routes on LiveWire devices.

Hi all,
The New Interfaces for Musical Expression (NIME) conference comes to London
in 2014!
We would love to receive contributions from LAU community, and given the
LAC conference is around the same time, this make the chance for a great
summer of weird sounds!
Please see below the call for proposal and circulate as appropriate.
The Performance and Installation call for NIME 2014 is out now and the
deadline for submissions is in LESS THAN TWO WEEKS' TIME: 1st
December, with no late submissions accepted. We would therefore like
to encourage everyone to get thinking about what they might like to
present in this category!
For NIME 2014, we will be hosting performances and gigs in a variety
of venues around Central London. We plan to make some of these events
open to the public and are looking for really high quality
performances, from proven performers and makers.
We hope to include a diverse range of performances, and so are keen to
receive proposals which are out of the ordinary. For example, work
which focusses on the body in performance, such as the human voice,
the body in dance, or indeed music which makes audiences dance. We
also encourage works which challenge the conventions of NIME, such as
notions of liveness, or the role of notation, language or code in
performance. Historical perspectives on music performance technology
are also welcomed, for example work which combines computation with
textiles, augments traditional instruments, or draws on
complementarity with visual forms. With the increasing influence of
the maker movement, we also welcome proposals which include ad-hoc,
DIY and open source instruments.
If you have something you'd like to show in a less polished way, you
can simply tell us you'd like to show a 'performance demo' and these
will be most likely programmed in smaller venues closer to the
conference site.
The call can be viewed at the link below.
http://www.nime2014.org/call-for-participation/
If you have any questions, please contact the artistic committee here:

Hope to see some of you there!
best wishes,

Hello,
I wanna share with community my very simple Jack session manager. It console app and is intended to use from scripts ( even if this is rc.local ;-) - or it could be linked to some icon/activator on desktop ;-)
It use libconfig for store settings and CDK ( ncurses ) for display while it "watching".
In save mode it works almost like jack_session_notify ( this part of code was partially borrowed, but was fixed, optimized and adapted - e.g. it doesn't store duplicate connections. take care of trailing slash in session directory, use libconfig etc. ).
Load mode was written from scratch. It start stored apps, restore it's connections and then it works like watchdog. It should be ( and it is at least for me ;-) useful for live performances.
There is also simple script which merge this two functionality, and it can also start start jack and wineserver (in persistent mode), export WINE_RT variables etc.
Check this url:
http://sourceforge.net/projects/nxjsm/
I use this already in my band, so let this publicity of our song will be my "salary" ;-)

We are happy to announce the next issue of the Linux Audio Conference
(LAC), May 1-4, 2014 @ ZKM | Institute for Music and Acoustics, in
Karlsruhe, Germnany.
http://lac.linuxaudio.org/2014/
The Linux Audio Conference is an international conference that brings
together musicians, sound artists, software developers and researchers,
working with Linux as an open, stable, professional platform for audio
and media research and music production. LAC includes paper sessions,
workshops, and a diverse program of electronic music.
*Call for Papers, Workshops, Music and Installations*
We invite submissions of papers addressing all areas of audio processing
and media creation based on Linux. Papers can focus on technical,
artistic and scientific issues and should target developers or users. In
our call for music, we are looking for works that have been produced or
composed entirely/mostly using Linux.
The online submission of papers, workshops, music and installations is
now open at http://lac.linuxaudio.org/2014/participation
The Deadline for all submissions is January 27th, 2014 (23:59 HAST).
You are invited to register for participation on our conference website.
There you will find up-to-date instructions, as well as important
information about dates, travel, lodging, and so on.
This year's conference is hosted by the ZKM | Institute for Music und
Acoustics (IMA). The IMA is a forum for international discourse and
exchange and combines artistic work with research and development in the
context of electroacoustic music. By holding concerts, symposia and
festivals on a regular basis it brings together composers, musicians,
musicologists, music software developers and listeners interested in
contemporary music. Artists in Residence and software developers work on
their productions in studios at the institute. With digital sound
synthesis, algorithmic composition, live-electronics up to radio plays,
interactive sound installations and audiovisual productions their
creations cover a broad range of what digital technology can inspire the
musical fantasy to.
The ZKM is proud to be the place of the LAC for the fifth time after
having initiated the conference in 2003.
