The CLAM project is pleased to announce the first stable release of Chordata, which is released in parallel to the 1.4.0 release of the CLAM framework.

Chordata is a simple but powerful application that analyses the chords of any music file in your computer. You can use it to travel back and forward the song while watching insightful visualizations of the tonal features of the song. Key bindings and mouse interactions for song navigation are designed thinking in a musician with an instrument at hands.

This application was developed by Pawel Bartkiewicz as his GSoC 2008 project, by using existing CLAM technologies under a more suited interface which is now Chordata. Please, enjoy it.

CLAM 1.4.0, 3D molluscs in the space

March 8, 2010


The CLAM project is delighted to announce the long awaited 1.4.0 release of CLAM, 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 Group.

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. Video
  • 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. Here you can see some related Videos.
  • 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 documentation… Video
  • 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 implemented.

You can download them from the download page. Source, windows, debian and ubuntu packages are available. Contributed binaries for other platforms are welcome.
