[CLAM] CLAM Music Annotator 0.3.1 released

[Pau Arumi]

May 8th 2006,
CLAM Music Annotator 0.3.1 released


What is the CLAM Music Annotator?
---------------------------------

Is an application of the CLAM framework [1] that can be
used to visualise, check and modify music information
extracted from audio: low level features, note segmentation,
chords, structure... The tool is intended to be useful for
(though not limited to) the music information retrieval
research whenever you need to:

- Supervise and correct the results of automated audio
   feature extraction algorithms
- Generate manually edited annotations of audio as training
   examples or ground truth for those algorithms.

You can learn more about Music Annotator in its wiki page,
which includes screenshots and videos galleries:

http://iua-share.upf.es/wikis/clam/index.php/Music_Annotator

The application comes with two example extractors. One that
computes low level descriptors and another that performs
chord detection.
It also features useful views such as the "tonnetz" and
"key space" to visualise the tonal features (chords,
notes...)

CLAM Music Annotator is GPL.


What's new from last (0.2) version ?
------------------------------------

This is a major release which have at least duplicated the
number of important features.
- Ported to Qt4
- New chord extractor
- Colourful animated visualisations
- Improved application work-flow (project building, etc.)
- It also works as a collaborative annotation tool (BOCA
   client)

See the changelog [2] for a complete list of changes.
or the wiki [3] for general information.


How to install it?
------------------

In Windows we provide a binary installer which includes
all the needed libraries (including Qt4) and ready-to-use
sample data.

For Linux and Mac OSX we don't provide binaries at this
moment (though we plan to do in short).
Source tarballs can be downloaded from the web and complete
build instructions can be found in the INSTALL file.

The chord extractor extracts segments labeled with chords.
It uses Christopher Harte algorithm with some minor
variations. It has been developed as a collaboration between
the Queen Mary University of London and the Universitat
Pompeu Fabra (UPF) of Barcelona.

The "keyspace" view is a great contribution of Jordi Bonada
and Emilia Gomez, at UPF.
