What is Moreesc ?

MOREESC is an application for the calculations of the auto-oscillations in wind instruments, designed originally for single reed instruments but it can be used for brass too. It takes advantage of a modal decomposition of the acoustic pressure field in the bore, or of its input impedance, to let you compute the sound of any strangely-shaped instrument.


MOREESC is written in the Python language. Compiled code is used for the numerical computation core, wheras Python is the high-level language allowing simple postprocessing and glue actions.


The package is distributed under the Cecill-C license and freely available for scientific use. MOREESC is a typical research program wich is provided "as is", with no guarantee whatsoever.


The code is developed and maintained by Fabrice Silva (silva[at]lma.cnrs-mrs.fr).
