The first unified LV2 release, LV2 1.0.0, is out.
This release merges the previous lv2core package with all the official
extension packages, as well as example plugins, lv2specgen, and
additional data. From a developer point of view, the biggest change is
that all LV2 API headers can be used by simply checking for the single
pkg-config package "lv2" (for compatibility the previous "lv2core"
package is still installed). Implementations are encouraged to abandon
the "copy paste headers" practice and depend on this package instead.
With this release, several new extensions have become stable that
together greatly increase the power of LV2: atom, log, parameters,
patch, port-groups, port-props, resize-port, state, time, worker.

Praxis LIVE is an open-source, graphical environment for rapid
development of intermedia performance tools, projections and
A new build of Praxis LIVE is now available for download. While this
is mainly a bug fix release, it does see the Praxis command line
player added to the main installation, and work which paves the way
for distributing Praxis projects as standalone applications (coming
separately in the next couple of weeks).

I'd like to announce Folve, a FUSE filesystem that convolves audio
files as they are accessed.
It contains some examples to try right away.
If you want to filter your audio (for effect reasons, such as adding
reverbs, or just to linearize the frequency response of your
speakers), but your system doesn't provide a way to do this while
playing, your only option was to pre-process your audio files
accordingly. This is time- and disk-consuming, and you probably
wouldn't do it just for the fun of adding a reverb.
Folve solves this problem: it provides the audio files readily
convolved as you access them. It also provides a simple HTTP UI to
switch between filters.
Right now, Folve is tested with FLAC files; other audio file formats
do work, but not all work well with streaming.
This is the first public announcement on the announce/user list, but
Folve should already pretty usable. Please report problems and feature
requests through the github issue tracker.

The Xth Sense (software and hardware) is finally available on-line, get
binaries, DIY documentation, and tutorials at:
The digital interface is developed in Pd on a Linux machine; there's a main
software for the computation of incoming muscle sound (and virtually any
sound input), and the xth-sense-lib, a collection of 120 objects (and help
files) ranging from specific muscle sound methods, to everyday Pd patching
needs. It also includes a lot of GUI stuff, to facilitate building things.
Wanna the source? Here you go: https://github.com/marcodsad
What is the Xth Sense?
"**is a biophysical musical instrument. You can build your own and produce
music with it using the sound of your muscles.
It is free and open source, and it was named the “world’s most innovative
new musical instrument” by the Georgia Tech Center for Music Technology
(US, 2012). Its name is spelled ecsth sense (not tenth sense!). But it’s
way easier to call XS."
With the XS you can also control other software on your machine (video,
audio, light systems, etc.), send Voltage output to hardware, or control a
Hacks are encouraged by the design of the instrument itself. For some ideas

if anybody works with it, let me know!
We have users and works in Australia, Sweden, US, UK, Ireland, Spain,
Vietnam, Germany, Russia, Netherlands, and Italy, so far :)

The second selection in the new series called "Featured Artists" is up now
##### Louigi Verona #####
The idea behind the new "Featured Artists" section at the Linux Audio
Users Guide is to provide a promotional vehicle for the artists in our
vibrant community to showcase their work and to entertain and educate our
audience at the same time. Think of it as an exhibition or installation
where the "Art Gallery" is 450x800 pixels and the audience is people who
are genuinely interested in Linux Audio and multimedia.
If you are an artist and you would like to participate in this project we
will assist with programming and planning to help you realise your vision.
Please contact me directly if you would like to take part in this project.
