[linux-audio-dev] problems running latency-test 0.5.5 with latest VP kernel

by Maarten de Boer

Hello, I decided to give the voluntary preempt patch a try, so I just build a 2.6.9-rc3-mm3-VP-T3 kernel. But when I try to run the latency-test I run into the following problems: First of all, a simple-to-fix compile error in showtrace.c, caused by a missing " while ((c = getopt(argc, argv, "k:hpr:)) != -1) { while ((c = getopt(argc, argv, "k:hpr:")) != -1) { Now, I run as root, I create /dev/midi0, and I load the latency-test module mknod /dev/midi0 c 35 0 modprobe latency-test but if I configure (default) to use /dev/midi0, I get: error opening device Using rtc instead doesn't work either: error setting freq 1024 (the error is: Inappropriate ioctl for device) I searched a bit in the archives, and found mention of these problems, but no solution... And just an observation, the default wakeup_count=2 fails, because if (use_rtc && wakeup_count != 1) Any suggestion? Maarten

[linux-audio-dev] [ANN] QjackCtl 0.2.12 released!

by Rui Nuno Capela

Hi everyone, While lurking on CVS, here comes another step to this jack-audio-connection-kit Qt/GUI frontend: QjackCtl has been released: 0.2.12 is now public! Taken from the changelog: - Fixed some old and slow memory-leak due to redundand and repetitive call to jack_port_by_name() (discovered and solved, thanks to Jesse Chappell); some other free() and configure fixes were also applied. - Shiny display effect toggling has immediate feedback on setup dialog. - Added new usx2y driver support (EXPERIMENTAL). - New scaled connections/patchbay icons were added; meanwhile, all inline XPM icons were removed and brainlessly converted to PNG format. - New setup options as for the connections/patchbay view apprearence: larger icon sizes and font selection are now possible, to better ease manipulation on a touchscreen (feature requested for Lionstracs' Mediastation). - Connection line width follows icon size in discrete proportion. - "Other" setup options moved to a new dialog tab, "Misc"; new extreme item values, 32 and 16 frames, added to the drop-down list of the Frames/Buffer setting (as suggested by Mark Knetch). As usual, grab it from: http://qjackctl.sourceforge.net Cheers, and enjoy, rncbc aka Rui Nuno Capela

[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] [announce] radio programme (in German) on free software and contemporary music, LAD 2004, Wizards of Os

Thank you again very much for you contribution ... sorry. Best regards, Michael

[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
