The CLAM project is delighted to announce the long awaited 1.4.0 release of
the C++ framework for Audio and Music, code name '3D molluscs in the space'.
In summary, this long term release includes a lot of new spacialization
modules for 3D audio; MIDI, OSC and guitar effects modules; architectural
enhancements such as typed controls; nice usability features for the
NetworkEditor interface; convenience tools and scripts to make CLAM experience
better; enhanced building of LADSPA plugins and new support for LV2 and VST
plugin building; a new easy to use application to explore songs chords called
Chordata; many optimizations, bug fixing and code clean ups.
Many thanks to the people who contributed to this release, including but not
limited to the GSoC 2008 students and all the crew at Barcelona Media's Audio
Some details follow:
* Chordata is a new CLAM application which offers a user friendly way to
explore the chords of your favourite songs, using already existing technology
in the CLAM framework but with a much simpler interface. 
* The spacialization module and helper tools, contributed by Barcelona Media
 audio group, turn CLAM in tandem with Blender and Ardour, into a powerful
3D audio authoring and exhibition platform.
* Typed controls extend CLAM with the ability to use whichever C++ type as the
message for a control. So, not just floats, but also bools, enums, integers, or
envelopes can be sent as asynchronous controls. Examples on boolean and MIDI
controls are provided.
* NetworkEditor has been ported to the QGraphicsView  framework. Dealing
with heavy networks such the big ones used in Barcelona Media have pushed
many usability enhancements into its interface: multi-wire dragging, wire
highlighting, default port and control actions, network and in-canvas
* It also made necessary to provide a tool such clamrefactor.py to perform
batch high level changes to clam network XML files such as renaming processing
types, ports, or configuration parameters, changing configuration values,
duplicating sets of processings, connecting them...
* Music Annotator application now is designed to aggregate several sources of
descriptors and update them after edit. Descriptors are mapped to a work
description schema that can be graphically defined. Also semantic web
descriptor sources to access webservices such as MusicBrainz have been
You can download sources, windows, debian and ubuntu packages from the
download page. Contributed binaries for other platforms are welcome.
