Matching Pursuit and Short Time Fourier Transform packages for LastWave

Participants : Rémi Gribonval, Lorcan McDonagh.

METISS regularly contributes to the development of the LastWave signal-processing software, the kernel of which is developed by Emmanuel Bacry at the Center for Applied Mathematics of the Ecole Polytechnique. LastWave is published under a free software license model (GNU General Public License), runs on Windows, MacOS and Unix platforms and boasts a figure of nearly 300 registered users.

LastWave is an object-oriented signal processing software, which consists in several packages. METISS mainly contributes to the development, maintenance and publicity of the Matching Pursuit and Short-Term Fourier Transform packages. These modules have also been incorporated, independently of LastWave, into Fabien Brachere's Guimauve software, from the Midi-Pyrénées Astrophysics Lab/Observatory in Toulouse. METISS efforts this year have been targeted at extending the functionalities of the packages to deal with multichannel audio signals and source separation. A description of the various algorithms implemented in the packages can be found in [51] [49] [50] [48].
