Call for performers using FLOSS and recycled technology

by Jake Harries

Hi Some of you may be interested in this call. We're looking for audio and audio-visual artists to perform at a couple of small live sonic art events at Access Space this year. We're particularly interested in artists who use FLOSS audio and video tools under Linux with recycled technology, and who are resident in and around South Yorkshire, UK. Unusual approaches to diffusion and sound generation e.g. using recycled computer speakers, are welcome! Our first event will be on the Friday 23rd of July, the second on 29th of October, and run 6pm-8.30pm. If you are interested in the first event please email an example of your work no larger than 7 Mb or a link to a media file, a description of your proposed performance and any technical requirements to jake(a)access-space.orgby 21st of June 2010. For the second event please contact us by the 31st of July 2010. Access Space is an unusual venue for events of this kind as it is an open access media lab during the day and the technology available is all donated or recycled. About Access Space: Based in Sheffield city centre, Access Space is the UK's longest running open access media lab. We have been using Open Source Software and recycled computers to develop creativity, community, skills and resourcefulness for over ten years. We're a place for skill sharing, artistic endeavour, creative expression and collective knowledge. Access Space has also recently announced plans for a DIY FabLab. <<<<<<<<<<<<<<<<< Linux Open Source Sound project: http://loss.access-space.org/ <<<<<<<<<<<<<<<<< -- Cheers, Jake <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Jake Harries Digital Arts Programme Manager ACCESS SPACE Unit 1, AVEC Building 3-7 Sidney St Sheffield, S1 4RG, UK t: +44 (0) 114 249 5522 w: www.access-space.org Reg.

Intel Rate Matching Hub and USB soundcards

by Jeremy Jongepier

Hello all, Does anybody know if there is any relationship between the Intel Rate Matching Hub (http://www.intel.com/products/server/chipsets/3400-3420/3400-3420-overview.… and USB ID 8087:0020) and poor performance of USB soundcards? I've come across two separate forum topics about it: http://www.linuxmusicians.com/viewtopic.php?f=4&t=2588&st=0&sk=t&sd=a&start… http://ubuntuforums.org/showthread.php?t=806730&page=4 The user on the LinuxMusicians forum could acknowledge that with Windows he had the same performance issues so it's not Linux related but I just wanted to know if anyone else encountered this phenomenon. Best, Jeremy

The Drummer's 'G'igsaw: Upgrade + GUI for 'randomization'.

by Phil Hézaine

Hi all, (Sorry for cross-posting) A new version of Le Puzzle du Batteur - The Drummer's 'G'igsaw is available at: http://philippe.hezaine.free.fr/spip.php?article46 New: - GUI for 'randomization': You have to install Python 2.6.x from your Linux distribution with an activated Tk flag, so you'll benefit from the GUI and randomization fonctions. In fact now it's possible for each note to choose a random value for 'timing' (timestamps) and/or for Volume (dynamics). You'll find all details on the way to use this interface in pdf's application. - To edit your file /home/.vimrc is no more mandatory. - Apologies for the manual which is not totally translated yet. All comments are welcome. Have fun. Phil. PS. Thanks to Gabriel M. Beddingfield to point me in the right direction with Python and thanks to Brett Pershing Stahlman for his invaluable advices when I wrote this GUI. He didn't make the job but his kindness has always supported me all along the writing. For the short story, following my search of a random function for vim, Brett Stahlman sent me one of his own three months ago. Completely amazed by his work, this unimaginable gift pushed me to go thoroughly into my wishes, and bit a bit, I understood that it was possible to realize this project using Python. And Brett has encouraged me to do it. People have understood that my Python code is nothing in comparison of Brett's code in vim, even if it didn't cover all parameters at that time. I'll never know how to thanks him, I only have my mouth which says: "Thanks to Brett." It's a SuperSir.

audacity alternative?

by Greg

Hi all, I was wondering if you knew of a good alternative to Audacity. For whatever reason I just don't like it. What is a fast, solid sample editor? I liked mhwavedit but gave up on it because it seemed to unstable. Basically something like an Ardour jr. would be perfect. Is anybody using SND for this purpose? It's got a high learning curve and I have not seen much written about it online.

Fwd: Changes to the WebM Open Source License

by Niels Mayer

http://webmproject.blogspot.com/2010/06/changes-to-webm-open-source-license… ................ Changes to the WebM Open Source License Friday, June 4, 2010 | 9:20 AM You'll see on the WebM license page and in our source code repositories that we've made a small change to our open source license. There were a couple of issues that popped up after we released WebM at Google I/O a couple weeks ago, specifically around how the patent clause was written. As it was originally written, if a patent action was brought against Google, the patent license terminated. This provision itself is not unusual in an OSS license, and similar provisions exist in the 2nd Apache License and in version 3 of the GPL. The twist was that ours terminated "any" rights and not just rights to the patents, which made our license GPLv3 and GPLv2 incompatible. Also, in doing this, we effectively created a potentially new open source copyright license, something we are loath to do. Using patent language borrowed from both the Apache and GPLv3 patent clauses, in this new iteration of the the patent clause we've decoupled patents from copyright, thus preserving the pure BSD nature of the copyright license. This means we are no longer creating a new open source copyright license, and the patent grant can exist on its own. Additionally, we have updated the patent grant language to make it clearer that the grant includes the right to modify the code and give it to others. (We've updated the licensing FAQ to reflect these changes as well.) We've also added a definition for the "this implementation" language, to make that more clear. Thanks for your patience as we worked through this, and we hope you like, enjoy (and most importantly) use WebM and join with us in creating more freedom online. We had a lot of help on these changes, so thanks to our friends in open source and free software who traded many emails, often at odd hours, with us. Chris DiBona is the Open Source Programs Manager at Google. .................. Niels http://nielsmayer.com

Roland(Edirol) Cakewalk UA-1G ALSA support

by Giuseppe Zompatori

Hi, I was just wondering when and if an ALSA driver for this card will make it in the official tree. Patching USB IDs with the UA-101 seems to make this nice & cheap USB sound card work well in advanced mode. Its USB ID in advanced mode is: Bus 003 Device 002: ID 0582:00e9 Roland Corp. and in standard mode: Bus 003 Device 003: ID 0582:00ea Roland Corp. Also can I use usb quirks for the snd_usb_audio module to force operation in advanced mode till when it'll be supported? Cheers, -Giuseppe

Fwd: [LAD] minimal LV2

Here's how: but given that the result would be: 1) a host that explicitly understood some alternative plugin API 2) a plugin that, other than its manfest.ttl file and accompanying .so file, was barely an LV2 plugin at all 3) more specifically, a plugin that would not run in the majority of LV2 hosts its difficult to see why you wouldn't simply define your own plugin API. the discovery process has to be one of the least interesting parts of LV2 (or any plugin API that i can think of) and co-opting it appears to me to save oneself almost no work at all.

The rest of your list seems sensible, not including the windows port ;) Keep up the good work. Cheers, -Giuseppe
