[linux-audio-announce] ANN: Oscilloscope plugin 0.2.1

by Lars Luthman

Version 0.2.1 of the Oscilloscope DSSI plugin is now available here: http://www.student.nada.kth.se/~d00-llu/music_dssi.php?lang=en It has fixes for some bugs spotted by Sean Bolton: - The GUI will now actually quit when it receives a /quit command from the plugin host - There will be no /tmp/dssi_shm_tmpfile_* files left behind when the plugin and GUI exits - The Makefile uses pkg-config to get the compiler flags for DSSI, so it should work now even if your DSSI header is installed in a non-standard directory Thanks to feedback from Sean Bolton and Chris Cannam on the DSSI mailing list I know also know that the plugin works with ghostess-20050516 and the latest CVS version of Rosegarden (but not with any releases of Rosegarden). -- Lars Luthman PGP key: http://www.d.kth.se/~d00-llu/pgp_key.php Fingerprint: FCA7 C790 19B9 322D EB7A E1B3 4371 4650 04C7 7E2E

[linux-audio-announce] ANN: Oscilloscope plugin 0.2.0

by Lars Luthman

Here is an oscilloscope DSSI plugin that I've been hacking on the last few weeks: http://www.student.nada.kth.se/~d00-llu/music_dssi.php?lang=en It has two audio input ports and will display the two input signals as two waves in the display. The trigger level and direction is controllable, as well as the amplification and offset for each channel and the time resolution. Note that this plugin will NOT work with jack-dssi-host from version 0.9 of the DSSI package since that does not support audio input ports. It will work with jack-dssi-host or Om from current CVS (I haven't tested it with Rosegarden). Om 0.1.1 and earlier will not work because of an optimisation that breaks this type of plugins. The plugin includes a DSSIUIClient class that might be of interest to plugin UI writers using libsigc++ and Glibmm - it handles all the required communication with the plugin host and exposes public member functions and signals for the UI -> host and host -> UI OSC commands specified in the DSSI RFC. It can also handle the nasty business of setting up an initial shared memory segment for the plugin and the UI (the actual implementation of the shared memory handling is in a separate C file, so it could be useful for people who don't use libsigc ++ and Glibmm or even C++). Source code documentation is here http://www.student.nada.kth.se/~d00-llu/plugins/ll-scope/dox/html/classDSSI… and here http://www.student.nada.kth.se/~d00-llu/plugins/ll-scope/dox/html/dssi__shm… For more details about the plugin, read the README file in the source package. It's all GPL. -- Lars Luthman PGP key: http://www.d.kth.se/~d00-llu/pgp_key.php Fingerprint: FCA7 C790 19B9 322D EB7A E1B3 4371 4650 04C7 7E2E

[linux-audio-announce] [ANN] LinuxSampler 0.3.1

by Christian Schoenebeck

LinuxSampler [1] is a modular, streaming capable sampler. It was designed decoupled from any user interface, that is as sampler backend which can be controlled via network connection from an arbitrary place, using a custom, ASCII based protocol called LSCP [2]. [1] http://www.linuxsampler.org [2] http://www.linuxsampler.org/documentation.html Focus of this first release was an adequate support of the Gigasampler format, including experimental support for the new Gigasampler v3 format. For a complete list what is already covered and what is not, check the features site [3]. [3] http://www.linuxsampler.org/features.html Planned next: * strong synthesis optimizations * support for further sampler formats * instrument database system * implementation of further control interfaces like OSC [4] * SMP and network cluster support * as ports to other OSs are already on the pipe, maybe a new name :P You might want to use QSampler [5] as convenient graphical frontend to LinuxSampler. You can get everything from the downloads site [6].

[linux-audio-announce] ANNOUNCE: QSynth 0.2.3 released!

by Rui Nuno Capela

Hi, After a long time laying in the backyard, QSynth 0.2.3 is being released to the world :) Qsynth is a Qt GUI front-end application to the excellent fluidsynth soundfont2 engine. You can check it out, right away from: http://qsynth.sourceforge.net The fine print goes like there's no really big new features on this. After all its only a minor dot-realease. As you may find from reading the changelog, there's a: - New option for system tray icon and menu, which is known to be effective on KDE enabled desktops; support for freedesktop.org's system tray protocol specification has been included so this maybe also effective on Gnome2. - Setup options for alternate MIDI and Audio devices were introduced. - Output level meters get smoother and slightly layout optimized. - Set to ignore the SIGPIPE ("Broken pipe") signal, where available, as the default handler is usually fatal when a JACK client is zombified abruptly. - Messages window limit is now enforced only when the line count exceeds in one third the user configured line count maximum; if Qt 3.2.0+ is in use, the QTextView widget is otherwise set to the optimized Qt::LogText format. - Updated Mac OS X build instructions (README-OSX, by Ebrahim Mayat). That's it. Enjoy! -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[linux-audio-announce] ANN: Q-Faust

by Albert Graef

(Cross-posted to the Faust and Q mailing lists.) Hi all, I thought that some of you might be interested in a Faust [1] interface I created for my functional programming language Q [2]. The interface allows you to load and run Faust DSPs in Q. Those of you who attended Yann Olarey's Faust workshop and my talk about Q at LAC05 should have an idea of what I'm talking about. ;-) I think that Faust and Q really make a great combo, which allows you to do all your multimedia/DSP stuff using nothing but modern FP tools. The Q-Faust interface is currently only available in cvs, see the q-faust module at [3]. A few examples are included, such as a realtime synthesizer playable via MIDI. To build and run this stuff, you'll need the Q core system, Q-SWIG, and the q-midi and q-audio modules, all readily available from [2]. And, of course, you'll also need Faust [1]. Relevant links: [1] Faust homepage: http://faudiostream.sourceforge.net [2] Q homepage: http://q-lang.sf.net [3] Q cvs repository: http://cvs.sourceforge.net/viewcvs.py/q-lang Enjoy! :) Cheers, Albert -- Dr. Albert Gr"af Dept. of Music-Informatics, University of Mainz, Germany Email: Dr.Graef(a)t-online.de, ag(a)muwiinfa.geschichte.uni-mainz.de WWW: http://www.musikwissenschaft.uni-mainz.de/~ag

[linux-audio-announce] [nfo] GOTO10 workshop at 0KN0 - anASPintro - belgium july 2005

by propaganda＠goto10.org

The ASP Introduction workshop from goto10 and hosted by okno.be intends to introduce the students to the basics of Audio Signal Processing in the fields of realtime music production. The workshop is specifically made for people willing to develop their work in the digital sound field and for people curious about the processes involved behind audio software they already use. The workshop will also teach and demonstrate which free technologies are available for audio and video streaming. The workshop will end with an open placard event (headphone live festival - more infos soon). ASP and Audio Synthesis Audio processing is the manipulation, either measurement or filtering, of an analog (voltage level) or digital (binary numbers) representation of sound. In the Digital Signal Processing field, this implies the conversion of the signal from an analog to a digital one and vice versa with a focus on one particular domain (time, space, frequency,...). Audio Synthesis is the art of producing artificially generated sounds using various techniques. This creation can be done either in the analog world (current manipulation) or digital world (discrete values manipulation). topics 1. understanding the physical sound 1.1 the phenomenon of sound 1.2 perceived qualities (duration, pitch, loudness) of sound 1.3 quantitative measurements (time, frequency, amplitude) of such qualities 2. understanding the digital representation of physical sound 2.1 basic sampling theory 2.2 ADC & DAC 2.3 binary numbers 3. basic audio signal processing 3.1 adding signals 3.2 multiplying signals 4. synthesis 4.1 simple FM 4.2 simple wavetable 4.3 simple granular 5. samples/soundfiles 5.1 different soundfiles 5.2 loss vs. lossless compression PURE DATA PD (aka Pure Data) is a real-time graphical programming environment for audio, video, and graphical processing. It is the third major branch of the family of patcher programming languages known as Max (Max/FTS, ISPW Max, Max/MSP, jMax, etc.) originally developed by Miller Puckette and company at IRCAM. The core of Pd is written and maintained by Miller Puckette and includes the work of many developers, making the whole package very much a community effort. It's hard to describe the possibilities of such an environment as its field of creation is almost infinite. From audio processing, to video, 2D/3D, interactivity, on-line experimentation, streaming and sensors, Pure-Data can handle all of these and provide a rock stable system which is perfect for performances and installations of any kind. topics 1. messages vs. audio signals 1.1 how audio signal differs from message signal 1.2 how to see audio signals 2. audio building blocks and operators 2.1 oscillators 2.2 [+~], [-~] and others 2.3 ramping and envelopes 3. delay & filters 3.1 introducing delay 3.2 various types of filters 4. let's make 4.1 a FM patch 4.2 a sample playing patch 4.3 an effect patch MFP The aim of My First Packet is to provide graphical high-level modules dedicated to quickly build an audio/video mixing and streaming platform on linux and eventually OSX. MFP works like a high level and friendly environment built on top of PD, PDP and PiDiP. topics - what is an abstraction - presentation of the different possibilities - presentation of Open Sound Control - presentation of icecast, ogg, vorbis, and theora - building an audio and video streaming system --- SCHEDULE DAY 1 12h-19h | ASP and Audio Synthesis | one day with the blackboard ... | chun lee + aymeric mansoux DAY 2 12h-19h | Pure Data | Applied theory and osc~ fun | chun lee + aymeric mansoux DAY 3 12h-19h | MFP | let's connect and stream | chun lee + aymeric mansoux DAY 4 14h-2h | GOTO10/OKNO placard | http://leplacard.org | more infos soon. --- :DATE: JULY 11th-14th 2005 :HOST: http://okno.be :LANGUAGE: english :FEE: 60 euros :LOCATION: OKNO brussels 1080 - koolmijnenkaai 30/34 quai aux charbonnages :FOOD&DRINKS: free tea+coffee - softdrinks 1 Ã¢Â¬ :HOUSING: not included :HARDWARE: bring your own laptop :BOOKING: annemie -at- okno -dot- be --- http://okno.be http://goto10.org/-/aspintroduction.html -- GOTO10 ONE WAY NFO L!ST - HTTP://GOTO10.ORG IRC.GOTO10.ORG #GOTO10 TO UNSUBSCRIBE SEND A MAIL TO NFO-UNSUBSCRIBE(a)GOTO10.ORG
