[linux-audio-user] linuxjournal.com article on upcoming linux audio conference

by Joern Nettingsmeier

hi everyone ! it seems our friend dave has been very active again. in case you haven't seen it yet, here is a nice teaser for the 2nd linux audio conference in karlsruhe at the end of april: http://www.linuxjournal.com//article.php?sid=7514 best, jörn -- The handles of a craftsman's tools bespeak an absolute simplicity, the plainest forms affording the greatest range of possibilities for the user's hand. That which is overdesigned, too highly specific, anticipates outcome; the anticipation of outcome guarantees, if not failure, the absence of grace. - William Gibson, "All Tomorrow's Parties" Jörn Nettingsmeier Kurfürstenstr 49, 45138 Essen, Germany http://spunk.dnsalias.org (my server) http://www.linuxaudiodev.org (Linux Audio Developers)

[linux-audio-user] Intermitent Xruns...

by Russell Hanaghan

Hi, I setup Qjackctl with jack and have had it running fine under normal conditions on MDK 9.2 with the multimedia 2.4 kernel...I upgraded this system with MDK 10.0 today but am using the 2.4 kernel still. I use a Dell 650mhz / 256Ram laptop with LADSPA plugins ad a live FX box on my PA> Usually use AMS with Freeverb and a delay with midi control to switch FX on and off. I have set this laptop up in a CII docking station now that houses 2 SBLive PCI cards. I have them chained with a modified .asoundrc file that gives me 4 ins and 4 outs. I have been using Ardour as the host to test this setup. I am running 3 mono channels with a Chorus, Gverb and TAP Delay in eac respectively. Qjackctl, TOP and Ardour all report about 24% CPU load when all are active. I run acoustic guitar thru the Chorus channel separately routed to a channel on my mixer and I run the other 2 channels in Ardour back in stereo fed from an Aux send on the mixer for General Fx buss. The above setup works fine when I fire it up. I run the multi card set up (actually ttable from the Alsa website) at 512 2 RT (As root) The system stay stable with no Xruns for about 5 minutes then the sound will begin to distort. It will do that for a minute or so then Qjackctl shows an Xrun or 2 and it clears. Sometimes Jack will shutdown but not always. I try to shut down as many daemons and services as possible. The 2 SBlive's are on IRQ 10 (Host bridge to docking station I think) but nothing else on that interrupt. I have tmpfs setup. It seems like something is kicking in intermittently causing this but I see no spikes in Gnome Resource monitor nor anything odd watching it in TOP when the problem starts. Even though I upgraded the system, it did this previously as I have tested this once before on the same setup with MDK 9.2. Any ideas? This seems so close to being useful but the unreliable tendency is a show stopper for my needs. Thanks

[linux-audio-user] Weird sounds

by Vi

Hi, I'm using alsa with via82xx configured. And sometimes when I play sound with xmms, xine, etc. I get wierd noise on background (popping sound). When I go to alsamixer and change via dxs (even very litle) the sound desapears, but backround popping stays. If I'm changing pcm, it becomes more silent, but when I'm turning my speakers louder I still hear popping noise. The thing is that it's not happening always, but in 50% of cases. And there is no such problem under windows (so it's not the speakers who are guilty). I'm confused about this stuff. Please help. Thanks.

[linux-audio-user] ANNOUNCE: workshop Pure Data, Amsterdam

by derek holzer

WORKSHOP PURE DATA Netherlands Media Art Institute, Montevideo/Time Based Arts 26 - 29 May 2004 Fee: E 150,- Guests: Aymeric Mansoux, Derek Holzer, Frank Barknecht and Jaromil This workshop is meant for beginners and will focus on Open Source software for the real-time manipulation of audio and video. The dual package of Pure Data and GEM, offer a complete set of tools for sound, multimedia and VJ purposes. Topics will include: real-time audio and video processing with PD and GEM, RRADical PD, PDP and an overview of other free and open source audio and video tools for Linux. PD and GEM The dual package of PD [Pure Data] and GEM [Graphics Environment for Multimedia], developed under an open source model by an international community of programmers, offers just such a set of tools. Running under Windows, Linux or OSX, PD and GEM can be used in commonly available, inexpensive hardware as a complete multimedia environment. Both applications allow for the real-time manipulation of sound and image data within a visual programming environment which does not require any previous experience in traditional computer languages. PDP is a set of external objects to PD developed by Tom Schouten, runs under Linux and OSX, and are based on the idea of processing data in packets. While it is primarily used for video, the basic structure of PDP allows any kind of data to be processed into any other kind of data. Images can be converted to textures, which can be mapped onto 3D objects, converted back to images, changed into sound, re-rendered again as image, and so on. The possibilities are endless. RRADical PD (Reusable and Rapid Audio Development) is a set of patches created by Frank Barknecht in order to make Pure Data easier and faster to use for newcomers and for people who are looking for a collection of standardized music tools similar to what commerical software packages such as Reason or Reaktor offer. The workshop is for beginners. The level will go up while the week progresses. The first day will be dedicated to basic PD and for those who bring their own machine, an installation session. For applications please contact Marloes de Valk marloes(a)montevideo.nl <mailto:marloes@montevideo.nl> Purpose While many tools exist for sound, multimedia and VJ purposes, few of them are designed with an open architecture which allows artists to configure the tools they use themselves. Fewer still are free. The importance of an open source development model may seem academic at first, but in fact there is a strong need for a workshop of this kind. The fees, licenses and restrictions that come with commercial software become more and more restrictive every day, and the knowledge in the new media community of free and open source software is extremely limited. Coupled with this is the stigma that open source software, such as Linux, is "too difficult" for artists to use. This workshop aims to provide the tools which can be taken away and put to use immediately and the knowledge of how to use them productively. Details The workshop sessions will be held in the Netherlands Media Art Institute. Over the 4 days of the workshop, 12 participants will learn about PD, GEM, and PDP, working under the Linux operating system. Topics of the workshop will include: * Crash course 'Installing PD and GEM for beginners' with invited guests * Basic PD with Derek Holzer * Basic GEM with Aymeric Mansoux * Intermediate PD with Derek Holzer * RRADical PD with Frank Barknecht * PDP with Aymeric Mansoux * Clinic * Presentation and jamm session At the end of the fourth day a short presentation of the workshop will take place. This presentation will be open to an audience invited by the participants. The workshop will finish with a "Jam Session", in which the participants can share the creations they have made with each other and with the audience. Invited Guests Frank Barknecht (D) Open source developer, sound artist and the creator of the End-User Abstractions project (RRADical PD, Reusable and Rapid Audio Development) which makes it possible to learn using Pd in a top-down way, making PD more accessible and open. <http://footils.org> Aymeric Mansoux (F) Artist and author of pure-data tutorials/articles for MusicRun, Co-Founder of a group dedicated to alternative digital art study and Co-Founder of Goto10, an organization dedicated to set up and produce electronic live events. <http://www.bleu255.com> Derek Holzer (NL/US) Sound artist currently based in Utrecht. Initiated the Acoustic Space Lab Project, an "open source sampling project" which invites artists to use a database of samples gathered at a former Soviet spy station to create a common body of work. <http://acoustic.space.re-lab.net/lab> <http://www.umatic.nl> Jaromil (I) Jaromil is an italian GNU/Linux programmer, author and mantainer of three free softwares and a operating system: MuSe (for running a web radio), FreeJ (for veejay and realtime video manipulation), HasciiCam (ascii video streaming) and dyne:bolic. http://rastasoft.org/ <http://rastasoft.org> Marloes de Valk Educatie Nederlands Instituut voor Mediakunst, Montevideo/Time Based Arts Keizersgracht 264 1016 EV Amsterdam T 020 6237101 F 020 6244423 E marloes(a)montevideo.nl www.montevideo.nl Marloes de Valk Educatie Nederlands Instituut voor Mediakunst, Montevideo/Time Based Arts Keizersgracht 264 1016 EV Amsterdam T 020 6237101 F 020 6244423 E marloes(a)montevideo.nl www.montevideo.nl ______________________________________________ SPECTRE list for media culture in Deep Europe Info, archive and help: http://coredump.buug.de/cgi-bin/mailman/listinfo/spectre

[linux-audio-user] Mandrake 9.2 to 10.0 upgrade but using the 2.4.22 patched kernel...

by Russell Hanaghan

HI, Can anyone tell me if I could upgrade my Mandrake laptop from 9.2 to 10.0 but continue using the 2.4 kernel? I see lots of comments on the fact that the 2.6 kernel does not seem very reliable for DAW stuff right now. My MDK 9.2 setup works well but some of the front end "X" stuff is a bit flaky and the upgrade would give me all the new versions of KDE, GNOME, etc. Thanks R~
