[linux-audio-dev] [ANN] QSynth 0.2.2 released!

by Rui Nuno Capela

Hi everyone, After a great long time, lurking on CVS, here comes another step to this fluidsynth's Qt/GUI frontend: Qsynth has been released: 0.2.2 is now public! Taken from the changelog: - Minor configure fixes. - Meanwhile, XPM icon(s) were brainlessly converted to PNG format. - Engine panel settings are now properly saved on stop/restart. - Icons were added to the engine tab selector context menu. - Master gain front panel control gets rescaled and now ranges from 0..200, with midpoint at 100 (unit gain). - Added Mac OS X build instructions (README-OSX, by Ebrahim Mayat). - Soundfont bank offset option gets its trial time (EXPERIMENTAL); please note that fluidsynth 1.0.5 is needed to build on this feature, which is being properly detected and only enabled at configure time. - Output level peak meters are now featured as an option (EXPERIMENTAL), which must be explicitly enabled on setup for those to show up; in addition, overall GUI refresh cycle period has been reduced from 200 to 100 msec. - Top level sub-windows are now always raised and set with active focus when shown to visibility. As usual, grab it from: http://qsynth.sourceforge.net Cheers, and enjoy, -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[linux-audio-dev] Example LADSPA 2 metadata editor

by Steve Harris

I've been giving some more thought to LADSPA 2 recently, and I've knocked up a quick editor for RDF/NTriples syntax plugin descriptions. The schema used is not a particularly clever one, I just rolled it as I was writing the code, and I'm not suggesting it for real use, its just to give a flavour of the format. http://plugin.org.uk/md-creator/ Runs in your browser (probably mozilla only - khtml may work) so requires no software installation - its all client side too. You need JavaScript turned on. Usage Add Plugin etc. create new form sections you can fill in Dump text shows a (crude and incomplete) description of the plugin Dump RDF dumps a machine readable description of the plugin Read RDF parses any RDF/NTriples data in the textfield and turns it into an ediable form. Example RDF/NTriples file: http://plugin.org.uk/md-creator/example.nt paste it into the textarea and click Read RDF to see it. Theres also a grpahical rendering of the example: http://plugin.org.uk/md-creator/example.png which may help explain it. The whole deal, UI, NTriples parser, RDF engine, NTriples serialiser is less than 600 lines of HTML+JavaScript (View/Page Source to read it), so I think that shows that this approach can be simple enough to implement. - Steve

[linux-audio-dev] Announcement: ltsb - linux textbased studio

by Julien Claassen

Hi all! Although still in the early - very early - stages, I finally decided to announce it: my webpage, http://ltsb.sf.net . I try to demonstrate how you can use a text-based linux environment (console) as a nicely equipped recording-studio. At the moment only the basic chapters of this guide and a few early audio-examples are online. But as time allows, I'll continue. Kindest regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net - the Linux TextBased Studio guide

[linux-audio-dev] some new code that may be of interest

by Dave Phillips

Greetings: Matt Flax sent these announcement to me recently, and since I've not had time to update the Linuxsoundapps site I'm passing them on the lists for now: MFFM Time Scale Modification for Audio <http://sourceforge.net/projects/mffmtimescale/> http://mffmtimescale.sourceforge.net/ This is an engine which stretches audio without changing its pitch. The C++ headers are really easy to use in 3rd party apps. MFFM Bit Stream <http://sourceforge.net/projects/mffmbitstream/> http://mffmbitstream.sourceforge.net/ This is a library which allows one to stream bits to/from files ... handy for those people who want to make an audio compression engine or player. MFFM Multimedia Time Code <http://sourceforge.net/projects/mffmtimecode/> http://mffmtimecode.sourceforge.net/ These C++ headers are great for managing time code ... it automaticly expresses time code in any base units ... which must be set up by the user ... can run any type of SMPTE, CDDA, etc. .. It is templated so you can handle any data type ... audio, video, audio/video.... It also includes a type II filter for audio processing ... this is very handy for filtering audio with FIR or IIR filters. Best regards, dp

[linux-audio-dev] International Linux Audio Conference 2005 (LAC05): Call for Papers and more

by Frank NEUMANN

Hi list, as had been announced here earlier, the 3rd International Linux Audio Conference (or "LAC05" for short) will take place on April 21st-24th, 2005, again at the ZKM (Zentrum fuer Kunst und Medientechnologie, Center for Arts and Media Technology) in Karlsruhe, Germany. The organizers are now happy to send out the Call for Papers, Call for Music and more. We have prepared a web site containing all the details, including the text of the Calls, submission instructions, mailing list/contact addresses and more here: http://www.zkm.de/lac The website is not fully equipped yet (e.g., the templates for Papers have not been finished, and registration is not yet possible), but this will be added in the next weeks. Please watch the "News" page for up to date information. Compared to the last 2 years, we have changed several points. With the conference growing both in numbers of talks and visitors, certain things need to be planned more precisely in advance. That is why we now have a review process for papers and mandatory registration (as well as some other smaller changes, see the web page for details). We hope that you will agree that this is only for the better. We hope for a lot of interesting and entertaining papers and talks, and look forward to meet you (again :-) in April 2005. One detail we can reveal already now is that we could "hire" Fernando Lopez-Lezcano to hold the keynote. If you know of other interested parties - local user groups, composers, other mailing lists or individuals - please forward this mail wherever appropriate. If you have any kind of questions about the conference or this call, please don't hesitate to contact us at: lac2005 _at_ zkm _dot_ de. Thanks for reading, The LAC05 organization team: Goetz Dipper (ZKM) Matthias Nagorni Frank Neumann -------------------------------------------------------------------------- LAC 2005 Calls ============== Call for Papers --------------- We invite submissions of papers addressing all areas of audio processing based on Linux and open source software. Papers can focus on technical, artistic or scientific issues and can target developers or users. This includes (but is not limited to) the following categories: * Computer Music * Music Production * Instruments * Drivers and Sound Architecture * Audio Distributions * Generic (Usage, Documentation etc.) The conference is held in English. In contrast to the last conferences we are asking you to submit elaborated papers rather than abstracts only, for the following reasons: * We are planning to publish conference proceedings (in print and online) and a conference CD. * Also, the conference has grown to such an extent that we have to limit the number of talks. All papers will be reviewed by a board of experts. Based on their recommendations the organization team will decide which talks will be accepted. If you want to present some work in progress rather than a complete paper, please consider the sections "Call for Project Notes" and "Call for Posters". Length of a paper is 4-8 pages. Papers should include an abstract (50-100 words). The abstract will be published separately on the conference website once the paper has been accepted. Also, papers should include up to 5 keywords. We are going to use these keywords to create an index of the proceedings. In general talks should take 20-30 minutes followed by 5 minutes discussion. If you think you need more time, please tell us. Please also notify us if you need a special technical setup. The technical standard setup will be: * microphone (head set) * projector with XVGA input (resolution 1024x768) * stereo speaker setup with mini jack input If you are not able to bring your laptop along with you, please notify us in advance. How to submit * File format is PDF. If you cannot produce PDF, contact us. Make use of the templates for paper formatting available at the web page. If this is not possible, please contact us. * See our check list to ensure that you do not forget to enclose all necessary information. * Send your paper and all necessary information until 10 Jan 2005 via email to this address: lac2005 at zkm dot de * You will be notified by 18 Feb 2005 whether your paper has been accepted. The reviewers may ask you to modify your paper in order to be accepted. The deadline for the final version is March 11, 2005. Important Dates 10 Jan 2005: Paper submission deadline 18 Feb 2005: Notification of acceptance 11 Mar 2005: Final version deadline 21 - 24 Apr 2005: Conference Call for Project Notes ---------------------- A project note is very similar to a paper, but does not need to be as elaborated and complete. Length of a project note is 2-4 pages. Project notes should include an abstract (50-100 words) and up to 5 keywords. In all other respects, the same criteria apply as for papers (see section "Call for Papers"). How to submit * File format is PDF. If you cannot produce PDF, contact us. Make use of the templates for paper formatting available at the web page. If this is not possible, please contact us. * See our check list to ensure that you do not forget to enclose all necessary information. * Send your project note and all necessary information until 10 Jan 2005 via email to this address: lac2005 at zkm dot de * You will be notified by 18 Feb 2005 whether your project note has been accepted. The reviewers may ask you to modify your project note in order to be accepted. The deadline for the final version is 11 Mar 2005. Important Dates * See dates for "Call for Papers" Call for Posters ---------------- With respect to their content poster presentations do not differ from regular talks: Posters can focus on technical, artistic or scientific issues and can target developers or users. See section "Call for Papers" for more info on this. Since we never had poster sessions up to now, here is a short description of what we are planning: Authors will bring a printed poster to be attached to a wall. There will be enough space to have about 10 posters presented simultaneously. Authors are expected to present their posters by short presentations (max 10 min), which they repeat several times during the whole poster session. A whole poster session will take 2 hours. People can walk around and freely choose which poster presentation to attend and can visit several presentations during the whole poster session. Two reasons why we decided to include poster sessions into the conference: * We can have more presentations in the same time * It allows for more "interactivity" with the audience Note: It is not planned that you use your laptop while presenting the poster. The poster will not be part of the conference proceedings. However you may additionally provide a paper or project note on your topic which will be included in the proceedings. See the section "Call for Papers" for more info (especially about the paper templates). The poster itself will be included on the conference CD and on the conference website. How to submit * File format is PDF. If you cannot produce PDF, contact us. There is no template for posters. * Add a separate abstract (ca 50-100 words). The abstract will be published on the conference website once the poster has been accepted. * Add a separate list of up to 5 keywords describing your poster. We are going to use these keywords to create an index for the conference CD and online. * See our check list to ensure that you do not forget to enclose all necessary information. * Send your poster and all necessary information until 10 Jan 2005 via email to this address: lac2005 at zkm dot de * All submissions will be reviewed by a board of experts. See section "Call for Papers" for more info on this. Important Dates * See dates for "Call for Papers" Call for Workshops/Tutorials ---------------------------- With respect to their content workshops do not differ from talks: Workshops can have technical focus as well as artistic or scientific focus. Workshops can be targeted to developers as well as users. See section "Call for Papers" for more info on this. Workshops will take place in seminar rooms. Attendance is limited to ca. 10 people. A workshop can take significantly longer than a talk (2-3 hours). We have already had workshops during the last conferences, but most of them were rather spontaneously initiated. We will still retain the possibility of spontaneous workshops, but additionally we would like to encourage people to submit carefully prepared workshops. You might submit a paper along with your workshop proposal. If accepted, the paper will be included in the conference proceedings. Make use of the paper templates (see section "Call for Papers"). How to submit * See our check list to ensure that you do not forget to enclose all necessary information. * Send an abstract (ca. 50-100 words), all necessary information and your (optional) paper until 10 Jan 2005 via email to this address: lac2005 at zkm dot de * The abstract will be published on the conference website once the workshop has been accepted. * All submissions will be reviewed by a board of experts. See section "Call for Papers") for more info on this. Important Dates * See dates for "Call for Papers" Call for BOFS ------------- "Birds Of a Feather Sessions" - among all the events during the conference, the BOFS will be the most spontaneous. So there is no deadline for BOFS submissions. A BOFS is a chance for like-minded users and/or developers to exchange experience and knowledge about a specific topic. This can happen in a public place like the ZKM cafe or in a seminar room (if available). If you like to suggest a topic for a BOFS, do not hesitate. Send an email to lac2005 at zkm dot de, include an abstract (50-100 words), a title for the BOFS, and possibly additional remarks. Call for Music -------------- There will be again some concerts during the conference. We are looking for music that has been produced completely or mostly under Linux and/or with open source software: * Interesting demos of sound synthesis, sound processing, etc. This should include a short talk/introduction to the technique used. * "Serious" compositions, to be played in a concert-like context * Electronica, Chill-Out, Ambient etc. If you want to participate, send your composition(s) to this address: Linux Sound Night ZKM | Institut fuer Musik und Akustik Lorenzstr. 19 D-76135 Karlsruhe Germany Make use of one of the following media formats: * Media: Audio-CD, DVD or CD-ROM * File formats: aiff or wav * Channels: mono, stereo or multi-channel * Samplerate: 44.1 or 48 kHz * Resolution: 16 or 24 bit Include the following items with your submission (in English): * Requirements (speaker setup, instruments etc.) * A filled-in and signed printout of the form available on the web. For the printed programme and to be published online and on the conference CD, in continuous text (no table or list please): * A short commentary on the compositions (ca. 150 words) * A short Curriculum Vitae (ca. 100 words) Deadline for submissions is 10 Jan 2005. A jury will select the compositions that will be performed/played. Furthermore, the jury will give out 3 prices to participants to contribute to their travel expenses. Besides artistic criteria and technical reasons, these criteria apply for the selection: * Tape pieces or pieces which are performed by the composer herself will generally have more chances to get included. * If we get more pieces than we can include in the programme, composers who are attending the conference are preferred. Terms and conditions for participation can be found in the form mentioned above. This form includes among other things: * I will receive no fees whether my composition is played or not. * GEMA fees (in case of performance) will be paid by ZKM. * The material I send to ZKM will not be returned. Additionally to this Call for Music, there will be an open stage called "Plug & Chill - The Linux Jam Night" at Saturday night (23 Apr 2005), where attendents of the conference are invited to perform their pieces in a less "official" context. There is no deadline for this, so people can decide during the conference if they want to participate. However if you already know that you want to participate, do not hesitate to inform us. Send us an email to lac2005 at zkm dot de and include a description of your equipment and a short characterisation of your music (keywords only). During the conference it is possible to register at the info desk. Note that there is a time limit for "Plug & Chill". If we have received too many registrations already you might not get a slot. Contributions to "Plug & Chill" should not exceed 10 min. There will be a room at ZKM where people can meet during the conference and rehearse for "Plug & Chill".

[linux-audio-dev] xruns, VP kernel, interrupts

by John Hedditch

Hi all. Does anyone have any ideas on what this message means: Unexpected hw_pointer value [1] (stream = 0, delta: -106, max jitter = 128): wrong interrupt acknowledge? It seems to accompany the xruns I get with the 2.6.9-rc2-mm4-VP-S7 kernel. Otherwise, this gives the best results I've yet got with jack. Incidentally, has anyone ever had an xrun-free system with jackd -R -d alsa -p64 ? Cheers, John
