Re: [LAU] jackd watchdog: timeout - killing jackd

by Julien Claassen

I can't use envy24control, but everything seems right. Before I was able to use these settings without a problem. Since then I changed kernels though. I think it might be some kernel problem.

jackd watchdog: timeout - killing jackd

by Nicolas Peltier

Hi everybody, i have that jackd message when activating both realtime and duplex option (not with capture only or playback only) : jackd -R -p128 -dalsa -dhw:0 -r44100 -p1024 -n2 jackd 0.103.0 JACK compiled with System V SHM support. loading driver .. Enhanced3DNow! detected SSE2 detected apparent rate = 44100 creating alsa driver ... hw:0|hw:0|1024|2|44100|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 44100Hz, period = 1024 frames, buffer = 2 periods ALSA: final selected sample format for capture: 32bit little-endian ALSA: use 2 periods for capture ALSA: final selected sample format for playback: 32bit little-endian ALSA: use 2 periods for playback jackd watchdog: timeout - killing jackd Killed I have an egosys julia (driver ICE1724), on an ubuntu studio distribution (gutsy). The weird thing is that it had worked with a classic ubuntu on feisty. That problem appeared with the gutsty update. I have already tried a lot of parameters combinations and suppose (but not sure) that the clue is elsewhere. Thanks for your help, Nicolas

[ANN] QjackCtl 0.3.2 (unstable-qt4) released!

by Rui Nuno Capela

Greetings, It must be what should be called one late "Fall cleaning": right after yesterday's Qsynth release, and before going into full-speed season compromises, I'll just let it all go as is :) That's it, the world-famous Qt GUI front-end to the incomparable JACK Audio Connection Kit is here and now, shouting for a general heads-up. Sort of ;) QjackCtl 0.3.2 (unstable-qt4) has been released! It's all in the change-log: - Patchbay port matching has been slightly extended, this time allowing for the multiple or as many-to-many connections between socket plugs, provided these are specified in proper regex form (after a patch proposed by Dave Moore, thanks). - A new option to start the program minimized when the system tray icon is enabled, is now available from Setup/Misc/Start minimized to system tray (as kindly suggested by Marc-Olivier Barre). - Regression from QSystemTrayIcon (Qt4 >= 4.2) implementation, at least on X11 environments: while the main application widget was minimized to the system-tray, closing any other top-level widget was causing the immediate and unexpected application shutdown. - Some portaudio backend settings are now being enabled, specially suited for the jackdmp flavouring. - Server mode display blinking, usually shown as the RT indicator, is now an option (Setup/Display/Blink server mode indicator when started). - Tool/child windows position and size preservation fixed. - The connections/patchbay auto-refresh option has been finally removed due to several user requests, although deprecated for quite some time now it has been the probable cause of some periodic xrun occurrences due to graph-locking in jackd (while making Geoff Beasley angry in the process:). - Messages line limit was not being checked, now honored. - Simple as it could ever be, the build executive summary report is now given on configure. - Patchbay snapshot got its socket and port ordering back. - ALSA Sequencer support is now an optional feature on setup, preventing the annoying "MIDI patchbay will be not available" warning message, ruining window placement on Linux systems where the snd-midi-seq kernel module is not loaded or not favorable (eg. OSS) at startup (by request from Jussi Laako). - Get configure to try and detect the correct qmake location and insert it the search order, so let the qt4 tools take precedence when --with-qt option is given and older qt3 ones coexist and are found located ahead in the PATH. - The connections widget is now being properly refreshed, due to some quirk in the QTreeWidget which was preventing some items, specially the expanded ones, to disappear in the void. Meanwhile, with a hand from Stephane Letz, the client/port lookup method was changed to prevent duplicated, missing entries or worse, crashes due to weird behaved windows applications. - The xrun count stats can now be reset simply by middle clicking on the systray icon or the main window's display area (thanks to patch sent by Dominic Sacre). - An improved version of the "shiny" background image was issued. The original somehow looked like two different images put together, probably most apparent on a bright TFT screen (by Dominic Sacre). - A warning is now being issued, asking whether one wants to remove a corresponding Patchbay connection, when client/ports are being disconnected over the Connections window, thus avoiding automatic reconnection annoyance due to normal active Patchbay behavior. - The infamous "Keep child windows always on top" global option is now supposed to behave a little better when disabled, layering child windows as naturally as far the window manager dictates. - Input/Output Channel setting is now allowed to be greater than 32; the special default text is now displayed, also on Input/Output Latency and Priority settings spin-boxes. - Andreas Persson just sent a patch that makes it possible to compile and run qjackctl with Qt version 4.1. Applied without hesitation, thanks. Hurry, the source tarball, as some other binary forms, might be found in the usual and official place: http://qjackctl.sourceforge.net http://sourceforge.net/projects/qjackctl Cheers && Enjoy -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

new releases

by Fons Adriaensen

Some new stuff on <http://www.kokkinizita.net/linuxaudio/downloads> Two new shared libraries: zita-resampler-0.1.0 zita-convolver-0.1.0 Both C++. Unlike the libcl* series which are my 'personal toolset' that I assume nobody will want to re-use, the zita series of libraries will be fully documented. The resampler already comes with HTML documentation, for the convolver this is 'under construction'. This release of zita-convolver is provided mainly as a dependency of jconv-0.2.0 Command line JACK app for real-time fft-based partitioned convolution with non-uniform partition size. Provides low or zero delay processing at moderate CPU loads. Any convolution matrix up to 64 * 64 as long as your CPU(s) can take it. From the README: New in this release ------------------- - The convolution engine has been separated into a shared library, libzita-convolver. For more information on the internals of the convolution engine, see the documentation provided with this library. - A non-real-time, file processing version of jconv, called fconv, has been added. It accepts the same configuration files. The input can be any file readable by libsndfile. The output will be a 24- bit WAV or WAVEX (for more than 2 channels). - Large configurations requiring too much memory will fail with an error message rather than just crash with a segfault. - Now uses jack_client_open(), so multiple instances can be run even without using the -N <jack_name> option. - Optional use of FFTW_MEASURE. - Added the mkwavex utility, converts multichannel responses stored in separate files to a single WAVEX file. - New config files for some AMB reverbs. The nicest one of these is York Minster, which really sounds great. Enjoy ! -- FA Laboratorio di Acustica ed Elettroacustica Parma, Italia Lascia la spina, cogli la rosa.

[ANN] Aqualung 0.9beta9 released

by Tom Szilagyi

The Aqualung development team is pleased to announce the latest release of the Aqualung music player. Aqualung is an advanced music player originally targeted at the GNU/Linux operating system, today also running on FreeBSD, OpenBSD and Microsoft Windows. It plays audio CDs, internet radio streams and podcasts as well as soundfiles in just about any audio format and has the feature of inserting no gaps between adjacent tracks. The ChangeLog lists major new features and is included below. Packagers, please note that from this release, TagLib is no longer a dependency of Aqualung. Website: http://aqualung.sf.net Enjoy, Tom 2007-12-19 Tom Szilagyi <tszilagyi at users dot sourceforge dot net> * Aqualung 0.9beta9 http://aqualung.sf.net This is a major release bringing significant new functionality and many important fixes. All users are encouraged to upgrade. As always, the up-to-date User Manual is available at: http://aqualung.sourceforge.net/?tab=docs Major additions: * Fundamentally new Metadata system, using native decoders and private code instead of TagLib to provide complete support for reading and writing metadata, including ID3v1, ID3v2.3, ID3v2.4, APE, Ogg Xiph comments and FLAC picture frames, as well as read-only support for ReplayGain in Musepack stream data and various metadata received in internet radio streams. Aqualung also provides a batch tagger facility to quickly propagate Music Store metadata to file metadata. * Support for podcasts. Aqualung can subscribe to RSS and Atom audio podcasts, and automatically download and add new files to the Music Store. Optional limits for the age, size and number of downloaded files can be set. * Support for exporting files from Music Store or Playlist with audio transcoding and intelligent metadata transfer. Useful for burning your favourite tracks to CD, filling your portable player, etc. * Aqualung now compiles and runs on OpenBSD. * Smoother skin changing. * Option to disable skin support (for themed environments). * Lots of fixes, cleanups & refactoring. DROPPED DEPENDENCIES: * TagLib is not used anymore.

[ANN] Qsynth 0.3.2 (unstable-qt4) is out!

by Rui Nuno Capela

Yes, it's about time. Much as the long due FluidSynth 1.0.8 release, really "Its about funky time!". Time also for season greetings and some gift exchange. Don't ask for a second best, here you have the finest pair of socks for the holiday ;) Qsynth 0.3.2 (unstable-qt4) is out! The official download site is, as always have been: http://qsynth.sourceforge.net http://sourceforge.net/projects/qsynth Straight from the change-log: - A new option to start the program minimized when the system tray icon is enabled, is now available from Setup/Misc/Start minimized to system tray. - Regression from QSystemTrayIcon (Qt4 >= 4.2) implementation, at least on X11 environments: while the main application widget was minimized to the system-tray, closing any other top-level widget was causing the immediate and unexpected application shutdown. - Minor corrections on the output peak meter scale aesthetics. - Tool/child windows position and size preservation fixed. - Orphaned MIDI device name no longer mistaken when switching between MIDI drivers on engine setup. - A bit more of precision is achieved over the output peak meters. - Messages line limit was not being checked, now honored. - Simple as it could ever be, the build executive summary report is now given on configure. - Get configure to try and detect the correct qmake location and insert it the search order, so let the qt4 tools take precedence when --with-qt option is given and older qt3 ones coexist and are found located ahead in the PATH. - The infamous "Keep child windows always on top" global option is now supposed to behave a little better when disabled, layering child windows as naturally as far the window manager dictates. - Inspired on Andreas Persson patch, while on qjackctl-devel, which made it possible to compile and run with older Qt 4.1, similar arrangements were carried out on qsynth too, without hesitation. - Main panel spin-boxes gets accelerated when stressed (Qt >= 4.2). Cheers && Enjoy, -- rncbc aka Rui Nuno Capela

from cassette/LP to cd (which prog?)

by millward

I use Audacity to record the sound and save it to a WAV file. I make a copy, and work on the copy. I use Audacity to break up the huge WAV file into its various tracks and work on the tracks individually. That's easier on the CPU and if you screw up its not such a problem. There's a useful denoise filter on Audacity I sometimes use, but most of the real work is done with the Gnome Wave Cleaner. It's free. http://gwc.sourceforge.net The GWC has just about everything I need; noise filters, declickers, etc. After a track is clean enough, I use Audacity to amplify it to its maximum below the clipping barrier. If you're picky like I am, its a long and distressing job. Some records just can not be cleaned. I only clean records that there are no CDs for. Otherwise, its not worth the time and aggrivation. Good Luck!

Uses that Zyn patch of Folerol's

by Ken Restivo

This one makes better use of it: http://www.restivo.org/blog/podpress_trac/web/256/0/windsock.ogg I used my hack of sampling the Zyn patch, then loading the samples into Specimen, and thus being relatively RT-safe. -ken

Using wine-asio

by David Baron

I actually had an audio app running in wine "see" the wine-asio "driver". Now, how do I couple this goodie with a physical device, alsa port or jack client?? The app could "not start audio engine". No inputs or outpus were available to its dialogs choices.
