Release 0.90 finally available

After several pre-releases, testing and bugfixing you can now find the final 0.90 release in our donwload section. Note that now you have the option of downloading the CLAM framework as a binary for your platform or with the source code. Major highlights of this release are the new binary distribution, a new build system based in Scons, major rework of some applications, support for VST plugins...

The release announcement:

 Wed Feb 8 2006   CLAM 0.90 Released
======================================

'New multiplied build-system, fancy applications and inter-
 connectivity'

    What is CLAM?
    CLAM is a framework for research and application development
    in the Audio and Music Domain. It offers a conceptual model
    as well as tools for the analysis, synthesis and processing
    of audio signals.


We are glad to announce that our new 0.90 release is already
available at our (also brand new) website: http://clam.iua.upf.edu.
This release represents a big step forward to our soon to come
first stable 1.0 release and includes major improvements.

For the first time the CLAM framework and all related applications
are available in binary form for all major platforms: deb packages
are provided for Ubuntu/Debian GNU/Linux, dmg images for Mac OSX
and setup executables for Windows. This change has represented a
complete but necessary (and painful!) rework of our build system,
which is now based on small binary libraries and uses Scons as
the build tool. We expect it to reduce drastically the complexity
of the compilation and installation of clam applications for the
end-user.

Other major improvements include a complete rework of the SMSTools,
application GUI, which is now based on Qt, as well as many
additions to the Annotator app.

A CLAM Network can now also become an Open Sound Control (OSC)
node, opening up the possibility of interconnection to external
applications. In the 'Application Prototyping' chapter we'd like
to mention that we have also added complete tools to create both
VST and LADSPA plugins out of a previously designed network.
It is also worth noticing the possibility of creating stand-alone
applications with a GUI created using the great Qt-designer and
the CLAM Qt-plugins. Such standalone applications can behave
either as a Jack client (for GNU/Linux and Mac OSX) or use audio
backends like alsa or Portaudio.

Please read these and other improvements in the attached changelog
and visit our website and/our mailing list for further announcements.

Although we are continuing to work toward the 1.0 release and we
expect to come up with new improvements soon, we hope all these
additions already convert the framework into a more usable and
useful tool and, as always, we expect as much feedback as possible
from all our users.

New year: New website, new logo, new address

If you are reading this you will have noticed that we have changed the design of both our website and our logo. The main website address has moved to http://clam.iua.upf.edu. So, even though we will keep the redirection for some time, please update your links.

This website has been possible thanks to the grant from the Catalan government. It is currently being translated and will soon be available in catalan and spanish.

CLAM 0.90 Prereleases available

During the coming weeks we will be publishing a series of pre-releases for 0.90. You will find them in the donwload section. Apart from the regular source code from now on we will be publishing binary versions of the framework for all major platforms (GNU/Linux, Mac OSX and Windows). Because this represents a major change in the distribution we do expect your collaboration and reports.

CLAM support from the Catalan Government

This week it was finally made official: the Catalan Government (Generalitat) will be supporting CLAM through a special grant. The main goal of such grants is to support quality Free Software development in Catalonia. We hope to make good use of the grant and be able to bring CLAM to its 1.0 release. You can read the official announcement here.

CLAM at ISMIR 2005

At the ISMIR 2005 conference held in London we presented a paper about one of the applications we are developing in the framework: the Annotator. You can read the entitled "The CLAM Annotator: A Cross-platform Audio Descriptors Editing Tool" here.

CLAM presented at ICMC 2005

Final release of CLAM 0.8.0 "Prototyper with streaming SMS transformations"

After two preview releases We are glad to announce the final 0.8.0 version of CLAM. This release has been thoroughly tested in GNU/Linux but not in Windows and OSX, which is a time consuming task to do with our current build system.

Announcement letter

After two preview releases We are glad to announce the final 0.8.0 version of CLAM. This release has been thoroughly tested in GNU/Linux but not in Windows and OSX, which is a time consuming task to do with our current build system. The reason for thas is very simple: The current build system in Win and OSX is not completely automatic and requires some hand-tweeking. Instead of loosing time on that, we prefer concentrating effords in a new build system based on scons and library binaries, which promises being much more cross-platform frienly, among other goodies.

The next release (0.8.1) with the new build system will happen soon, because we have already been successfull in our first tests compiling CLAM library binaries and linking apps against it.

Now, going back to our current release, these are some of the important additons since 0.7.0

• Rapid application-prototyping. Build a CLAM application in two easy steps: Designing the processing network with the NetworkEditor and the application GUI using QtDesigner and the CLAM plugin featuring widgets for visualizing streaming data.
• Annotator. Another new CLAM application. It is a manual edition tool in which you can visualize and edit low-level and high-level descriptors of virtually any kind, segmentation marks.. The idea is to offer a tool for fine-tuning, visualizing, editing and testing description extraction algorithms.
• Enhanced CLAM Networks. NetworkEditor can run SMS transformations in streaming. Moreover the processing network can receive controls from Open Sound Control (OSC) messages and translate outcoming controls to OSC messages.
• QtPlots. Now features editable segmentation marks on all the plots, a break-point-function editor with auralization, a spectrogram plot and other goodies. See the doxygen doc to learn how to use it.
• XML enhancements including better error handling and reporting, an experimental backend based on libxml++ as an alternative to XercesC++ and partial document operations. Libxml++ is planned to be the official back-end on future releases but still some work is needed on error messages reporting.

For details in CLAM-specific new features, please refere to the ChangeLog

Compared to the last preview (pre2) release, these are the additions : (sumarized)

New libxml++ back-end, CLAM::Audio bugfixes and interface changes related to SetDuration and SetEndTime (keeping back compatibility), and lot and lots of small bugfixes and code cleanup.

CLAM to be presented at the Linux Audio Conference 2005

Our submitted paper "CLAM, an Object Oriented Framework for Audio and Music" has been accepted at the 2005 Linux Audio Conference.

We look forward to meeting you there!

CLAM release 0.7 'Easier deployment, better plots and Processing Networks'

We are glad to announce CLAM long-waited release 0.7. Main highlights in this release are:

• An easier deployment on GNU/Linux. After rewriting the configure.ac we are happy to say that now CLAM is easier to install on any distribution. If you are one of those that tried to install CLAM and you gave up because you didn't know how to handle the dependencies, please try this new relase. Among other things, you are now allowed to disable support for certain libraries at configure time.
• Progress in the CLAM Processings networks mode. We are almost there. Very soon you will be able to become a real clammer without writing a single line of code through the already usable Network Editor.
• Better Plots. Built using the QT framework and the qwt library we added new and more convenient plots with features such as: an audio plot with temporal markers, the possibility of quickly changing the color map to get a nice screenshot for your articles...
• Low-level descriptors have been thoroughly tested.

And much more... please read the changelog for more details.

Looking forward for your feedback.

CLAM at ISMIR
