CLAMs GSoC 08 Projects Announced
We are very happy to announce the final list of this year’s projects in the Google Summer of Code. We have been extremely fortunate to have a large number of great students apply for CLAM this year and we are confident that the 5 projects outlined below will have a huge impact on the project and the CLAM “family”:
Natanael Olaiz UNQ, Argentina
“Network scalability and Blender integration”
This is a two sided project. The first part will improve the usability of CLAM networks allowing users to hierarchically embed networks as a processing units. The second part consists in developing a set of Blender plugins and CLAM networks to drive audio spacialization based on direct
sound from Blender 3D geometries.
Yushen Han (Indiana University, US)
“Real-time woodwind instrument synthesizer using SMS models”
The project consists in building a real-time synthesizer based on CLAM processing plugins, using SMS models, allowing flexible sound timber manipulation. This project is a continuation to Greg Kellum’s 2007 GSoC project.
Francisco Tufro (UBA, Argentina)
“MIDI Implementation for Network Editor”
This project is both about developing all the needed and most common MIDI processings and also about doing all the required refactorings to the Framework in order to achieve this (i.e. Typed Controls).
Pawel Bartkiewicz (AGH University, Poland)
“Standalone chord extractor application”
This project is about adapting CLAM’s chord extraction technology into an standalone application focusing on usability for instrument players. This project will integrate existing visual and processing components and it will have impact on the interaction between realtime and offline CLAM components.
Wang Jun (Chinese Academy of Science, China)
“AnnMerger-to stand on the shoulders of the masses”
This project goal is add into Annotator the ability of combining several sources of several kinds (webservice, database, files, extractors) into a single project. Secondary goals are providing new data sources and polishing the program workflow.
Read here for more details on the projects:

CLAM in GSoC 2008!
We are glad to announce that 2008 summer is also going to be a Summer of Code for CLAM. Google just announced the list of mentoring organizations for GSoC 2008 and CLAM is in it!
Now we seek smart students who enjoy coding free software so that they can earn some bucks for the summer. Last year, GSoC 2007 was a very fun and productive experience and we are willing to repeat it. Take a look at the CLAM GSoC 2008 wiki page for more information on how to apply and some sample ideas for projects.
We are waiting for you!

CLAM 1.2, the GSoCket plugged-in release
We are jubilous to announce CLAM 1.2 “GSoCket plugged-in release”. We had to wait for some months to make this release as we had to redeploy the multiplatform release infrastructure. Thus, the feature buffer of this release is pretty full. It incorporates both, the results of the Summer of Code students work and the involvement of David and Pau with the crew at Barcelona Media Foundation Audio Research Line.
We want to thank the involvement of GSoC students Hernan Hordiales, Bennet Kolasinsky, Greg Kellum, Andreas Calvo, Roman Goj and Abe Kazemzadeh, Google Inc, and Barcelona Media audio lab members for their precious involvement in CLAM.
A summarized list of changes follows. See also the CHANGES files for details, or the development screenshots for a visual guided tour. As usual binary packages for Windows, MacOSX and several flavors of Linux are available to download.
Summary of changes:
The most exciting feature is the new plugin system (acalvo) which enables third party algorithms to be distributed separately
from the core binaries. LADSPA plugins support has been enhanced and a first iteration on FAUST integration. The wiki contains how-to’s that cover most of that.
Most of the GSoC work come as plugins: a SMS Synthesizer (gkellum), a Voice synthesis/analysis (akazem) and some some cool guitar effects (hordia). Also not included as plugins but in the main repository several enhancements have been done on the SMS transformations (hordia) and the tonal analysis (rgoj).
Some interesting work has been done on the Barcelona Media Audio Lab on having a system to simulate 3D room acoustics which can be reproduced on several exhibition systems. Some precomputed room databases are available to try. Check the wiki NetworkEditor Tutorial for more information.
Regarding the applications, Network Editor incorporates new usability enhancements, a new on-line Tutorial and a new Spectrogram like view. The Annotator received Bennet Kolasinsky attention improving its the flexibility of its interface, the practical effects are multiple segmentation and low-level descriptors panes and that we are pretty close to visualization and auralization plugins.
Enjoy.

Two CLAM journal articles
The past few weeks a couple of CLAM-related journal articles have been published in two top-tier journals.
The article entitled “A framework for efficient and rapid development of cross-platform audio applications” - coauthored by Xavier Amatriain, Pau Arumi, and David Garcia - has just appeared in the ACM Multimedia Systems Journal. This can be considered as the “ultimate” CLAM article. Apart from presenting the main features in CLAM, we talk about the metamodel and some of the patterns present in the framework design.
Also Xavier Amatriain published the article entitled “A Domain-Specific Metamodel for Multimedia Processing Systems” in the IEEE Transactions on Multimedia. This is a more detailed and justified explanation of the metamodel that was derived while designing and implementing the CLAM framework.
CLAM team at Googleplex
Last month Pau Arumi and David Garcia from the CLAM team attended the Google Summer of Code Mentor Summit at Googleplex in Mountain View, California. Hundreds of mentors from many of the participating projects were invited to a one-day workshop where different issues related to the Summer of Code and Open Source in general were discussed. It was a great opportunity for the CLAM team to make connections with related projects and meet many interesting people.

CLAM articles at Polish Linux Magazine
Polish journal Linux Magazine has recently published two articles about CLAM, written by Pawel Wolniewicz. First — dealing with Music Annotator, SMSTools, and Voice2MIDI — and second, describing development of audio application, using Network Editor, accompanied by Prototyper. They were published in July and August issues.
Both articles were written in Polish.

CLAM at the Campus Party
The Campus Party is one of the world’s largest geek parties, with over 7000 participants
this year. Google is one of the hosts of the developers zone and every day it held special sessions on the Summer of Code inviting students and mentors to explain their experience. Xavier Amatriain from the CLAM team was invited to one of those sessions*.
More than a talk about CLAM it was a short overview of our wonderful experience in the GSoC. We were told the talk will be added to Google’s podcasts soon, will keep you informed.
*Actually, and to be clear, the project that was hosted was Joomla (ex-Mambo). It just happened that I (X. Amatriain) showed up very last minute and they invited me to talk for 5 minutes (many thanks to the Joomla guys and Google Spain!).

CLAM at Catalan Free Software Conference - See you in Girona!
We’ve been accepted this paper on Visual Construction of Audio Applications with CLAM in the 6th Jornades de Programari Lliure, which this year is held in Girona.
So next week –yes, that soon!– CLAM developers –Pau and David at least– will talk and (mostly) do live demos of the cool visual application construction features. The conference program seems to be still provisional. We’ll update this news as soon as the timetable gets confirmed.
Update (July 5th): Our talk will be Friday at 13:30. Just a little bit later than (another) interesting talk on GStreamer and Elisa by Andy Wingo, one of the Fluendo guys –a company also also based in Barcelona.
We hope to meet many old and new friends there. See you in Girona!

CLAM 1.1, The `More eye-candy, please` release.
After a very intense development months since the last 1.0 release, the CLAM crew is glad to announce that CLAM 1.1 is ready to download. It comes with many new features and code clean up. Most important improvements are found in the Visual Prototyping front: new 3D-looking widgets, new data viewers and control surface; and a simplified way to bind controls between the user interface and the processing network.
This release has been cooked-up under the umbrella of the Interactive Technology Group at the UPF lead by Josep Blat. So we thank their support! It also features the work from contributors such as Zach Welch; as well as the first patches from Google Summer of Code program —for example LADSPA and FAUST support and some work on Annotator widgets.
A summarized list of changes follows. See also the CHANGES files for details. New audio related widgets were added to be used on the NetworkEditor and the Prototyper. Such widgets include data views such as the BarGraph which can display LPC’s, MFCC’s. Nice control widgets were also added. The ControlSurface, for instance, to control two scalar parameters by moving a point. Some widgets were gathered from the LAC community, such as PkSampler PovRay generated widgets, and nice knobs we enhanced from QSynth and Rosegarden. Thanks to the developers of those projects for making them GPL and being so supportive while integrating them in CLAM. With all those widgets, users now can visually build more appealing applications such as the new examples we include with Prototyper: A real-time gender change, or real-time spectral effects.
The TonalAnalysis (Chord extraction) now takes advantage of fftw3 performing 4 times faster! The KeySpace visualization was also optimized so now tonal analysis runs even on very slow computers.
NetworkEditor and Prototyper usability have been enhanced. They exploit the new in-control bounds parameters to automatically set up bounded control senders widgets. Also, NetworkEditor have proper multi-processing selection features.
On different fronts, the code-base has been reduced by getting rid of Fltk and Qt3 modules since we are now focusing on Qt4, and the documentation have been restructured and now it offers new programming how-tos.

CLAM 0.97 released
Another release in the series of "often releases" till 1.0. The code-name for this release is Debian Packages: less is more as we have reduced the number of debian packages. Now all clam libraries comes packaged in a single .deb. In addition, we now keep architecture independent example data in different packages. In the future we plan to extract functionality and dependencies out of the big package to smaller plugin packages. Audio back-ends, codecs and processing collections are good candidates for this. This is actually that the road gstreamer and other projects take.
Remember that you can install them by adding a new source in your /etc/apt/sources.list
deb http://clam.iua.upf.e../download/linux-debian-sid ./ deb http://clam.iua.upf.e../download/linux-ubuntu-edgy ./ deb http://clam.iua.upf.e../download/linux-ubuntu-feisty ./
Next release 0.98 (due very soon) will take MacOSX packages definitively back. By now, the CLAM build system is already prepared for mac, so if you want to compile the apps, you'll find instructions in this how-to. Thanks Volker for all the feedback he is providing!
For details on this release changes, check the CLAM changelog and the NetworkEditor changelog.

Publicada la versió 0.95 de CLAM
Després d'uns quants mesos sense cap nova versió estable però molta activitat de desenvolupament, ens plau anunciar la nova versió 0.95 de CLAM.
La novetat més important d'aquesta versió és l'aplicació NetworkEditor 0.4, amb una interfície d'usuari (UI) refeta de dalt a baix, usant Qt4.2, i molta feina en millores de usabilitat i estabilitat, i noves funcionalitats de prototipatge visual.
En que consisteix el prototipatge visual d'aplicacions (o plugins d'audio)? Edita una xarxa d'audio usant el NetworkEditor, després edita la seva interfície gràfica d'usuari amb Qt Designer i els plugins (de widgets) de CLAM. Finalment, l'apliació Prototyper et permet executar la xarxa d'audio amb la seva interfície d'usuari.
Això es mostra molt millor en aquest ràpid tutorial
Aquesta nova versió ve amb molts nous processings, la majoria transformacions espectrals. Però volem destacar el tonal-analysis que identifica acords en temps-real, i les seves visualitzacions relacionades. Aquest codi està basat en la feina d'investigadors de la Universitat Queen Mary a Londres i la Universitat Pompeu Fabra a Barcelona. Podeu trobar més crèdits a l'About del NetworkEditor.
Aquests i moltes altres millores poden ser llegides al ChangeLog.
This release brings new packages for Linux (Debian sid/etch, Ubuntu edgy and feisty) and Windows installers. In Linux, you can simply add new sources to /etc/apt/sources.list
deb http://clam.iua.upf.e../download/linux-debian-sid ./ deb http://clam.iua.upf.e../download/linux-ubuntu-edgy ./
Tant en Linux com en Windows les aplicacions queden ben integrades amb l'escriptori i venen amb diversos exemples apunts per ser usats. En Mac OSX, els paquets (.dmg) estaràn disponible en les properes setmanes.

Xarxes de CLAM gegantines!
What happens when you project a large complex Network that is being designed in the NetworkEditor into a 3-story high immersive sphere? See for yourself.
New real-time monitoring of CLAM development
Check out the CLAM testfarm page. Each new code check in (commit) awakes a number of testfarm clients in different platforms. They build CLAM from scratch, run automatic-tests and even publish some installers. It is also useful to monitor the repository activity such as the updated files and the check in comments.
Testfarm is a CLAM brother project but not CLAM specific. So you can use it to monitor any development that can be managed with command-line. It is similar to Mozilla Thinderbox and Buildbot but more light-weight and with some interesting features like automatic diagrams.
Public subversion access
$ svn co http://iua-share.upf.edu/svn/clam/trunk
This command will create a local copy of the repository with the following main directories: CLAM, NetworkEditor, SMSTools, Annotator, Voice2MIDI. Installation instructions are on CLAM/INSTALL
To update the sandbox (local copy of the repository) do: $ svn up
To check for current revision and new changes in the repository do: $ svn status -qu
To commit: well, send patches to the list.

CLAM design patterns are presented at PLoP
The development team is currently at PLoP (Program Languages of Programming Conference) 2006 in Portland, Oregon, in conjunction with OOPSLA. We are presenting this catalog consisting on eleven design patterns that contains our experience developing the CLAM framework and other systems. The patterns aim at offering a generative pattern language that falls within a generic data-flow architecture. The catalog is divided in four categories:
- General Data-flow Patterns, that address problems about how to organize high-level aspects of the data-flow architecture, by having different types of modules connections;
- Flow Implementation Patterns, that address how to physically transfer tokens from one module to another, according to the types of flow defined by the general data-flow patterns. Tokens life-cycle, ownership and memory management are recurrent issues in those patterns; and finally,
- Network Usability Patterns, that address how humans can interact with data-flow networks.
Patterns at PLoP are discussed and improved in small writer's workshops, and we are very pleased to have Ralph Johnson as our workshop chair!
On a different matter of things, the new (still unreleased) Network Editor and Prototyper are getting a lot of improvements. To get an idea see the development screenshots gallery.

CLAM ha guanyat el premi ACM al Millor Software Multimedia de Codi Obert !
És un plaer anunciar que CLAM ha guanyat el premi ACM al Millor Software Multimedia de Codi Obert del 2006. Segons el jurat del premi: CLAM és un sistema remarcablement complert amb possibilitats impressionants. El premi serà entregat a la propera Conferència ACM Multimèdia . El concurs de la ACM (Association for Computer Machinery, l'associació professional més prestigiosa en l'àmbit informàtic) és un concurs internacional de prestigi que en aquests moments es troba en la seva tercera edició. L'any passat, per exemple, el premi se'l va emportar la llibreria OpenVidia per a Visió per Ordinador accelerada per GPU.
CLAM és coordinat per Xavier Amatriain a la Universitat de California Santa Barbara però es desenvolupa principalment a la Universitat Pompeu Fabra de Barcelona per un equip encapçalat per Pau Arumí i David García. En aquests moments CLAM es desenvolupa gràcies a un ajut de la STSI de la Generalitat de Catalunya.
Aquest premi culmina 5 anys de recerca i desenvolupament continuat. Els autors volen recordar i agraïr a tots els desenvolupadors que en algun moment hi han participat així com a tots els nostres usuaris i gent que ens ha mostrat el seu suport al llarg dels anys.

Publicada la versió 0.91.0 de CLAM: Transformacions espectrals, annotator, paquetes Linux i integració desktop.
Ens satisfà anunciar la nova versió 0.91.0 de CLAM que va de la mà amb Music Annotator 0.3.2, Network Editor 0.3.1 i SMSTools 0.4.1. Totes elles ja estan disponible per ser descarregades en forma de tarballs de codi i també de paquets binaris per Windows, Ubuntu dapper, Debian sid i Fedora Core 5. Els binaris per MacOSX no estan disponibles per aquesta release però prometem que hi tornaràn a ser d'aquí a poc.
Es tracta de la primera versió oficial que incorpora el nou CLAM Music Annotator amb extracció d'acords.
S'han afegit quasi 30 noves transformacions espectrals al repositori de processings. Algunes ja són directament usables desde el Network Editor.
La usabilitat de les aplicacions ha rebut una atenció especial en aquesta versió. Les aplicacions s'integren millor tant en l'escriptoris de Windows com de Linux. No menys important, hem afegit uns tutorials pas-a-pas a la wiki de CLAM per Music Annotator, SMSTools, Network Editor i Prototyper. I tots ells contenen exemples apunt d'usar.
Pots llegir aquests i altres millores al changelog. Esperem tant feedback com sigui possible. Apart de la llista de correu, és probable que ens trobis al canal #clam de FreeNode (IRC).

Publicada la versió 0.3.1 del CLAM Music Annotator
Tenim la satisfacció d'anunciar la publicació d'una nova versió de l'Annotator amb un munt de funcionalitats noves.
Per informació detallada sobre el Music Annotator, visita la seva pàgina wiki, la qual inclou una galeries d'imatges (captures de pantalla) i vídeos.
L'aplicació ve amb dos extractors d'exemple. Un que computa descriptors de baix nivell i un altre que fa detecció d'acords. També inclou gràfics útils com el "tonnetz" per visualitzar notes i el "key space" per visualitzar acords.
Què hi ha de nou desde l'última versió (0.2) ?
La versió que avui publiquem conté grans canvis. De fet, com a mínim ha duplicat el nombre de funcionalitats importants: Ha estat portat a Qt4; nou extractor d'acords; gràfics animats a tot color; millora de el work-flow de l'aplicació (contrucció de projecte, etc.) i també funciona com una eina d'annotacions col.laborativa (client BOCA)
Llegeix el fitxer de canvis (changelog) si vols una llista completa dels canvis. O la pàgina wiki per informació general de l'Annotator.
Com instal.lar-lo ?
Per Windows oferim un instal.lador (.exe) que inclou totes les DLLs necessàries (també Qt4) i dades d'exemple apunt per ser usades.
Per Linux i Mac OSX actualment no oferim binaris (tot i que planegem fer-ho en un futur proper). Estan disponible a la web paquets amb codi i per instruccions detallades sobre com compilar llegiu el fitxer INSTALL.
No et perdis la pàgina de descàrregues.
Aquesta guia pas a pas explica com fer funcionar l'extractor d'acords.

Traducció de la web al Català i Castellà
Segurament t'has donat compte del menú de llènguatge a la cantonada de dalt a la dreta. Amb aquestes traduccions tanquem un llarg capítol de canvis a la web (i esperem que es mantindrà tancat durant molt de temps!). Per reduir la sobre-feina de mantenir diferents versions de la web actualitzada el Maarten de Boer ha escrit uns quants scripts amb perl que per un cantó agafen les cadenes de la web original (en anglès) i per l'altre les corresponents traduccions en fitxers de text plà. Ha funcionat a la perfecció! I és molt probable que publiqui aquests scripts d'aquí a poc.
Potser també t'has donat compte que comencem a fer servir una nova wiki de CLAM que funciona amb mediawiki.

Ara teniu la opció de descarregar CLAM com a binari per la vostra plataforma o en forma de codi font. El punt a destacer en aquesta nova versió és la nova distribució en binaris (instal.ladors windows, dmgs per mac osx), un nou sistema de compilació basat en Scons, la reescriptura d'algunes de les aplicacions i suport per plugins VST.
Any Nou: Nova web, nou logo i nova direcció
Com que estàs llegint aquestes línies, probablament ja hauràs notat que hem canviat el disseny tant de la nostra web com del logo. A més, l'adreça web ha estat canviada a http://clam.iua.upf.edu. Així que, tot i que mantindrem una redirecció per algun temps, sisplau actualitzeu els vostres links.
Desembre 2005
Disponible la versió 0.90 "alfa"
Durant les properes setmanes publicarem una sèrie de versions "alfa" de CLAM 0.90. Les trobaràs a la secció de descàrregues. Apart del codi font (com pertoca un programari GPL), a partir d'ara publicarem versions binàries del framework per les tres principals plataformes: GNU/Linux, Mac OSX i Windows). Es tracta d'un canvi major així que esperem la vostra col.laboració i informes.
