LAC2010: Clarification on paper deadline

by Frank Neumann

Hi, since the webpage for the Linux Audio Conference 2010(*) was unclear on the deadline for paper submissions, please let me clarify this here: The deadline for _paper submissions_ is February 14th, 2010. Until yesterday, the webpage incorrectly mentioned "Call for Abstracts", which should have read "Call for Papers" instead. This has been corrected now. Additionally, some information about the desired size and other constraints for paper submissions has been added to the web page mentioned below. Please feel free to forward this mail to whatever people/mailing lists are suitable. Sorry for the trouble, Frank, on behalf of the LAC2010 organization team (*) http://lac.linuxaudio.org/2010/?page=participation

LAC2010: Paper deadline coming closer

by Frank Neumann

Dear all, the deadline for submission of papers for the Linux Audio Conference 2010(*) is coming closer (February 14th, 2010), and (like last year) the amount of submissions so far is..quite small. However, without papers and presentations this kind of conference cannot exist. I believe that most of the prospective paper submitters out there will probably wait until the very last minute (I recall in one case there was even a bit of a debate about "what exact time, and what time zone please?" :-), but it would be helpful to get an idea of the upcoming submissions. For this reason I am asking that if you plan to submit a paper, to give us/me a short notice (title, topic) of your planned paper (direct reply, no need to send that information to any of the addressed lists). This would help us in planning the next necessary steps. By the way, we are not considering to extend the paper deadline this year. Please feel free to forward this mail to whatever people/mailing lists are suitable. Regards, Frank Neumann, on behalf of the LAC2010 organization team (*) See http://lac.linuxaudio.org/2010

[ANN] jack_capture V0.9.40

by Kjetil S. Matheussen

(I don't agree about the linux-audio-* mailing list announcement policy, so from now on, program announcements will only be posted to linux-audio-announce(a)lists.linuxaudio.org !) Download from ============= http://archive.notam02.no/arkiv/src/?C=M;O=D jack_capture ============ jack_capture is a program for recording soundfiles with jack. The default operation of the program is executed by writing "jack_capture" in the terminal without any extra command line options: $ jack_capture ...which will record what you hear in your loudspeakers into a stereo wav file. Most important new features since 0.9.36 ======================================== * Direct support for mp3 using liblame. * Console cleanup. Terminal should not be messy when quitting jack_capture. * Better buffering schemes. * Less used memory. Features ======== * Autogenerated filenames are unique and humanly readable. * The 4GB size barrier for wav files is handled by continuing writing to new files when reaching 4GB. * Supports all soundfile formats supported by sndfile. (wav, aiff, ogg, flac, wavex, au, etc.) (option: -f <format>) * Supports mp3 by using liblame. (option: -mp3) * Option for writing raw 16 bit data to stdout. (option: -ws) * Built-in console meter, plus option for automatically starting and stopping the Meterbridge jack meter program. Port connections to Meterbridge are done automatically, and on the fly, by jack_capture. * jack_capture can connect to any input or output jack port. When "connecting" to a jack input port (i.e. a writable port), jack_capture constantly monitors which jack ports which are connected to the input port, and make sure jack_capture is always connected to the same ports. In other words, jack_capture will reconnect its ports automatically during recording to match the connections of the ports. This is for instance convenient when recording the playback ports since jack_capture can be started first, and then other programs can start and stop at any moment while all sound still should be recorded. * No limit on the number of jack ports jack_capture can connect to. (I.e. the --port argument can be specified more than once, plus that it accepts wildcard arguments. For instance, jack_capture --port "*" will connect to all current jack ports, both input and output ports, except jack_capture's own ports.) * Buffers are automatically increased during runtime to prevent underruns and to avoid wasting memory by preallocating too much. (handled by using lockless atomic fifo/lifo queues to store temporary sound data instead of ringbuffers) * The disk thread is automatically reniced to a higher priority when using more than half of the buffer. * Significantly better recording performance than Ardour. (probably because jack_capture writes all channels into only one file and that it is not creating peak files). (tested on athlonXP) * No problem writing at least 256 channels of 32 bit wav at once to a local hard drive. (tested on icore7)

Guitar-ZyX LiveOS [nds & x86] v0.4.1 released

by Douglas McClendon

Announcing the release of Guitar-ZyX-0.4.1 LiveOS [nds & x86] ===================================================================== About ----- Guitar-ZyX(tm) is a LiveDVD/USB operating system distribution, that can immediately boot both your Nintendo(tm)-DS, and your x86/64 PC, into a guitar pre-amp f/x processing appliance, complete with wireless dual screen touchpad remote control. You can even velcro or embed the NDS in your guitar if so inclined. In addition to switching among 77+ different f/x presets, the NDS remote control's touchscreen can also linearly control any two of about a hundred independent f/x parameters in real-time. I.e. a very cost effective TouchScreenWhammyPad. Guitar-ZyX-0.4.1 uses the excellent Rakarrack open source guitar-f/x software to provide effects. Guitar-ZyX-0.4.1 is derived from Fedora(tm)-11 and has compatable full access to the upstream software repositories including updates. Guitar-ZyX is entirely free and open source software, with all source available, for both the PC and NDS components. All necessary compilers and build tools are also included, allowing anyone to modify and enhance in any way their imagination and code-fu skills allow. ===================================================================== Information ----------- Guitar-ZyX is currently an *alpha* release. NO WARRANTY. Use at your own risk. Interested alpha-testers are encouraged to provide feedback on what works, and what still needs to be improved. For information on many other features, and the best current documentation, please review the latest release notes, available here filteredperception.org/smiley/projects/guitarzyx/relnotes/index.html or visit the main project page http://filteredperception.org/smiley/projects/guitarzyx ===================================================================== What's New In Guitar-ZyX-0.4.1 ------------------------------ Guitar-ZyX-0.4.1 is primarily a major upstream rebasing release. That is, now f11 based. But there are many enhancments to 'sidestream' projects. Here are the details- Guitar-ZyX MCP :: Version 0.2* of the MCP now includes a main menu system. This allows access to the filesystem in order to launch other applications such as DSOrganize, and dozens of ZyXdevSuite examples. Browsing visible SSIDs is now supported, and many more menu accessible features are just around the corner. There is now a command to download and execute updated MCP code via wifi, vastly easing development. Rakarrack-0.4.0.dmc :: The latest prerelease CVS sources including the fruits of my new cvs write access are included. Josep Andreu has made many bugfixes and improvements, including new skinnability and font scaling. Ryan Billing has added new DSP modules, which I'll eventually understand enough to properly explain. And my Global Wet/Dry is now an upstream feature with a slider even(FX%). And more presets from all of us. Rolling Echo is kind of interesting, while Tricky Dick is just an homage to a crook. Breaking News: rakarrack-0.4.2 with midi-learn was released the same day as Guitar-ZyX-0.4.1. An update will be available at some point, though compiling from source should be trivial for anyone interested. Guitar-ZyX JaMode :: The big sledgehammer session initiation scripts have been vastly improved. Now, when you select one of the JaMode commands from the ZyX submenu of the mainmenu, they will execute much more quickly, as well as utilizing an aesthetic splash screen with progressbar during the transition. There is one to launch a recording session, one to launch a practice (non-recording) session, and one to return to the normal desktop audio system. desmume-0.9.5 :: Every aspect of the MCP can now me developed and tested via emulation, except sadly wifi/networking. But still, that is a vast improvement over the bugs that were interfering with input handling in prior versions while in a 3D mode. Sound works, virtual cflash fatfs of the current directory sortof works, scaling the window, .... (recording movies still seems broken though) ZyX-LiveInstaller-0.2.2 :: The same enhancements and bugfixes that led to its availability in the official Blueberry release of SugarOnAStick, are now included in Guitar-ZyX as well. Many bugfixes, thanks to a much broader range of testing. VirOS and *ZyX :: Enhancements have been made to VirOS which make it robust and possible to build across major ancestor releases. Also, many other things, particularly in the traits, have been massively cleaned up, though probably as much cleanup remains to be done. Time will tell if this facilitates a much more rapid rebasing against f12. Note, that it will still be another release or two before integration with the relatively new upstream bootsplash is done. This is because f12 introduces a major rewrite of the initramfs infrastructure. qemu-0.11.1 :: /usr/local/bin/qemu is based on upstream sources, with kqemu support intact, which on my laptop yields a greater than 100% speedup even with linux kernel 2.6 for both the guest and host. Games :: Standard gnome-games like freecell/solitaire, and chess are available. Frozen Bubble is also included - a much better rip off than the one I coded partially in assembly more than a decade ago for a CoE project. And most importantly, PokerTH is now available for all of your open source online texas holdem needs. ... peace... -dmc ===================================================================== "Be Seeing You..." -6 ===================================================================== --------------------------------------------------------------------- Fedora and Nintendo are protected trademarks, whose holders in no way endorse or support this software. Guitar-ZyX, G-ZyX, CloudSession, and VirOS are also protected trademarks, and may only be used in the redistribution of unmodified versions of free and open source software that already includes them. ---------------------------------------------------------------------

rakarrack-0.4.2 is released

by Josep Andreu

Hi Rakarrack is a richly featured multi-effects processor emulating a guitar effects pedalboard. Effects include compressor, noise gate, graphic equalizer, parametric equalizer, flanger, chorus, echo with reverse playback, musical delay, reverb, digital phaser, analogic phaser, wah-wah, alien-wah, harmonizer, and three flexible distortion modules including sub-octave modulation and dirty octave up. Most of the effects engine is built from modules found in the excellent software synthesizer ZynAddSubFX. Presets and user interface are optimized for guitar, but Rakarrack processes signals in stereo while it does not apply internal band-limiting filtering, and thus is well suited to all musical instruments and vocals. Rakarrack is designed for Linux distributions with Jack Audio Connection Kit. http://rakarrack.sourceforge.net News: AUDIO: - Two new effects have been added: Analog Phaser and Derelict Distortion. - Limiter at the end of the chain. - Four new waveshape types: Crunch, Hard Crunch, Dirty Octave+ and Modulated Square improving all the Distortion effects.. - Four new LFO wave types: Ramp Up, Ramp Down, Zig-Zag, Modulated Square improving Chorus, Flanger, Phaser, Pan, etc. - Sub Octave in Distortion effects. - Reverse Echo. - Compressor support for adjustable knee, switch (Mono/Stereo), improved automatic gain function. - Global Wet/Dry (FX%) - Improvements in Wah-Wah, Tuner and Harmonizer. MIDI: - Up to 104 controllable parameters. - MIDI Learn for each preset, up to 20 effect parameters can be assigned to a single MIDI control message. - jack MIDI GUI: - Scalable Fonts - Background Image. - New Logo and Icons. - Minor things. PRESETS - 15 New Presets. - Improvements on most of the old ones. - Improved consistency between preset volume levels. DOCS: - Help updated. BUGS: - Fixed data problem with Big Endian architectures, now rakarrack runs properly on PowerPC and maybe others. - Fixed important CPU usage bug related to computation of denormal numbers. - Other minor bugs fixed. Thanks, comments and suggestions are welcome.

[ANN] MusE 1.0.1

by Robert Jonsson

Hello folks, Right on the heels of big One-O we've decided to release a minor update with some corrections, main features being some package improvements and a midi timing issue when running under very high priority. MusE : http://muse-sequencer.org [Fixes since 1.0] * Removed: Disabled watchdog thread. (T356) * Changed/Fixed: Thread priorites: Added command line switches for audio (-P) and midi (-Y). (T356) - Audio (-P) applies to dummy driver only. (Else audio priority is fixed by Jack). Fixes potential issue with midi timing when MusE was assigned a very high priority. * Added: Enable/disable LASH command line switch (-L), (if LASH support is compiled in). (T356) - Helps prevent some issues like auto-starting Jack, or automatically routing midi to fluidsynth (observed). * Fixed: BUG ID: 2879426: *.med does not save meta event types. (T356) * Fixed: Midi meters now show for each track even if they're all on same device and channel. (T356) * Applied: muse-destdir.patch Scripts and utils packaging fix submitted by Orcan Ogetbil. (T356) * Fixed: python detection exchanged for script from http://libvirt.org/ (rj) * Feature: Jack transport enable/disable in Midi Sync settings window. Stores setting per-song. (T356) - Should be Ok to use and test. Needs a bit more work. See jack.cpp and jackaudio.h * Fixed: Speedups of audio pre-fetch especially when moving the cursor around (seeking). (T356) [What is MusE again?] MusE is multitrack virtual studio with support for: * Midi (only Alsa yet) * internal softsynths, including soundfont player FluidSynth and sample player Simple Drums * DSSI softsynths, including VST instruments * with a patch to DSSI, VST-chunks are handled * Drum editor * Pianoroll * Conventional arranger * midi automation * and lots more * Audio * Jack * Jack transport * LADSPA plugins * VST plugins through dssi-vst * audio automation, old sch00l * and lots more [ChangeLog] For a complete list of changes, check the ChangeLog in the package or online at the sourceforge site: http://lmuse.svn.sourceforge.net/viewvc/lmuse/trunk/muse/ChangeLog?revision… [Download] http://muse-sequencer.org/index.php/Download The MusE team

Qtractor 0.4.4 - The Frisky Demivierge's in the wild!

by Rui Nuno Capela

What? No automation, yet? Yes I failed the promise once again. So what? What would you expect from this self-called über-procrastinator? As sure is one to say that this is the Year of Linux Desktop (YOLD:), I'll give you the shivers and command this one will be the year of Qtractor Automation. No kiddin' ;) Meanwhile, this new dot-release brings you several niceties, a couple of them have been waaay longer and dustier on the all-mighty-overdue TODO list than automation is. Rejoice! or else... Qtractor 0.4.4 (frisky demivierge) is in the wild! Release highlights: * LV2 plug-in support (NEW) * MIDI event list view (NEW) * Expedite audio/MIDI clip import (NEW) * DSSI plug-in output control ports feedback/update (NEW) * JACK transport, MMC, SPP control options (NEW) * Self-bounce/recording (FIX) * Audio/MIDI drift correction (FIX) * Anti-glitch audio micro-fade-in/out ramp smoothing (FIX) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.4.4.tar.gz - source package (openSUSE 11.2): http://downloads.sourceforge.net/qtractor/qtractor-0.4.4-2.rncbc.suse112.sr… - binary packages (openSUSE 11.2): http://downloads.sourceforge.net/qtractor/qtractor-0.4.4-2.rncbc.suse112.i5… http://downloads.sourceforge.net/qtractor/qtractor-0.4.4-2.rncbc.suse112.x8… - binary packages (Ubuntu 8.04 LTS; no LV2 support): http://downloads.sourceforge.net/qtractor/qtractor_0.4.4-1.rncbc.ubuntu804_… http://downloads.sourceforge.net/qtractor/qtractor_0.4.4-1.rncbc.ubuntu804_… - binary packages (Ubuntu 9.10): http://downloads.sourceforge.net/qtractor/qtractor_0.4.4-1.rncbc.ubuntu910_… http://downloads.sourceforge.net/qtractor/qtractor_0.4.4-1.rncbc.ubuntu910_… - user manual (ever still outdated): http://downloads.sourceforge.net/qtractor/qtractor-0.3.0-user-manual.pdf Weblog (upstream support): http://www.rncbc.org License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - For all the DSSI plugins that have output control ports, a host feedback/update process cycle is now being finally provided: all output control ports are now marshaled to their respective GUI process, rather often and when found open/visible. - MIDI clip editor (aka piano-roll) snap-to-beat behavior on edit mode is now kind of more like 'filling-in-the-blanks' (as Frank Neumann et al. wishes ;) - Fixed MIDI clip editor mistake when reverting to initial clip length, before closing and discard changes (thanks to Frank Neumann, for spotting this one). - LADISH Level 1 support has been added: SIGUSR1 signal trap just makes it a shortcut to File/Save. - Avoid parameter value flickering, due to duplicate command invocation, most evident when changing values massively on native Linux VSTi plugin editor GUIs (thanks to a detailed report on this odd behavior, from Mike of linuxDSP.co.uk). - Another TODO item bites the dust: MIDI event list editor, now accessible from the MIDI clip editor menu (View/Events) - Last used session directory is now made current on startup only when no filename is given on the command line (solving bug #2920244). - Current snap-to-beat setting (time quantization) now affects the anchor event only, while dragging, moving and/or pasting multiple events over the MIDI clip editor (aka piano-roll). - Make anti-glitch audio clip micro fade-in/outs independent from current buffer size as much as possible. - Audio/MIDI engine drift correction gets really sophisticated, with the help of (now old) ALSA MIDI tempo skew facility. - Edit/Clip/Import... menu option is now available for expedite clip insertion from audio and MIDI file requesters. - Set default session directory effective to file's location. - Audio track/clip recording process has been target to special re-factorization across the internal audio engine process cycle, in a late attempt to get self-bounce/recording effective and working consistently for all track layouts. - All session related dialogs are now set to window modality, (were set to default application modality before) allowing for continued input focus and interaction on all plugin/tool windows. - An off-by-one nasty old bug fixed in audio clip drawing, was causing instant crashes on certain zoom levels of the main track view. - Graphical MIDI clip representation regarding note/pitch range is now kept as much as possible across clip edits (cut, copy, paste, drag, move, delete, etc.) - LV2 plug-in hosting has finally come into actual implementation; only some and the most basic LV2 plug-in features are supported at the moment; probably there's no big advantage against the old LADSPA ones; there's some support for external UIs though; also, LV2 MIDI/Event bare-bones support is included but chances are it won't build nor work right on most of the setups out there. It's a WIP host implementation anyways, as is the whole LV2 spec. for that matter ;) - Connections filter is now reset when widget is shown through the View/Connections main menu or toolbar button. - Audio bus auto-connection option is now applied when creating or updating, newer or existing buses, respectively. - Global configuration state is now explicitly saved/committed to disk whenever View/Options... dialog changes are applied or when a session is loaded or saved. - Audio ramping spin-locking makes its smooth stuff, in an attempt to reduce glitching and crackling when editing (due to its own pseudo spin-locking) and toggling playback states. - JACK Transport, MMC Device, and MIDI Song Position pointer (SPP) control modes are now made optional (View/Options...), allowing for discretionary configuration: None/Disabled, Slave/Input, Master/Output or Full/Duplex (default). - Session files may now be dragged and dropped over the main track view and get loaded for business as usual (once quietly ignored). - In an attempt to mitigate potential stack corruption and sudden crashes, old commented out session pseudo-locks are now back in business while executing clip editing commands (cut, paste, drag, move, insert, delete) and playback is currently rolling. - Adjusted first-time application window size to fit into 800x600 screen size and with reasonable initial dock-ables layout. - Avoid duplicate snap-to-grid effect when changing the length of MIDI clip editor events across non-zero clip offsets (after a glitch reported by Ralf Mardorf). - Late audio track processing optimization, suppressing all plugin, mixer and monitor pass-through activity when given track is muted, either explicitly or implicitly (ie. other track is in solo state). - Entering System Exclusive events (SysEx) on the MIDI clip editor (aka matrix/piano-roll widget), yet something not fully supported anyway, even though allowed in edit mode, doesn't crash the whole damn thing anymore, while saving the clip to a file. - Strict aliasing avoidance, with plain and demanded use of 'union', as much as to stop nagging warnings from gcc >= 4.4.1 (last seen on src/qtractorMidiEvent.h hackery). - Visual correct play-head position while changing zoom levels, applicable to both main track and MIDI clip editor views. Cheers && Enjoy. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org
