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. Download: http://lv2plug.in/spec/lv2-1.0.0.tar.bz2 Documentation and more detailed change logs: http://lv2plug.in/ns/ More information about LV2: http://lv2plug.in/ Enjoy, -dr

[ANN] Praxis LIVE build:120912

by Neil C Smith

Hi All, Praxis LIVE is an open-source, graphical environment for rapid development of intermedia performance tools, projections and interactive spaces. 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). Website - http://code.google.com/p/praxis Release notes - http://code.google.com/p/praxis/wiki/ReleaseNotes Videos - http://praxisintermedia.wordpress.com/2012/07/30/video-rough-cuts-1/ If any of you who've been playing with Praxis LIVE would be interested in submitting example projects for the next release, please get in touch with me off-list. Thanks and best wishes, Neil -- Neil C Smith Artist : Technologist : Adviser http://neilcsmith.net

Announcement: Folve, a FUSE filesystem that convolves audio files on-the-fly

by Henner Zeller

Hi, I'd like to announce Folve, a FUSE filesystem that convolves audio files as they are accessed. https://github.com/hzeller/folve#readme 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. -henner

Xth Sense: instrument, code, schematic, tutorial On-line now

by Marco Donnarumma

(sorry for x-post) Dears, I wished so much I could have joined you at Stanford this year... :( but....! The Xth Sense (software and hardware) is finally available on-line, get binaries, DIY documentation, and tutorials at: http://res.marcodonnarumma.com/projects/xth-sense/ 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 prosthetic arm. Hacks are encouraged by the design of the instrument itself. For some ideas see: http://res.marcodonnarumma.com/projects/xth-sense/#get-started We have a (newly born) user's forum, courtesy of Create Digital Music/Motion; the forum lives at: http://createdigitalnoise.com/categories/xth We are on also on Facebook (imagine!): http://www.facebook.com/XthSense 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 :) hope it is useful to some of you, cheers, -- Marco Donnarumma New Media + Sonic Arts Practitioner, Performer, Teacher, Director.

Featured Artist : #2

by Patrick Shirkey

Hi, The second selection in the new series called "Featured Artists" is up now at: http://linux-audio.com Featuring ##### Louigi Verona ##### ******************* Background info ******************* 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. Cheers -- Patrick Shirkey Boost Hardware Ltd
