The software and associated database were developed within the ANR ECHANGE project, with the participation of Gilles Chardon, Laurent Daudet, François Ollivier and Antoine Peillot.

NACHOS (Nearfield Acoustic HOlography with Sparse regularization) is a downloadable companion software for the journal paper [38] , distributed to comply with the "reproducible research" principle. It performs the reconstruction of operational deflection shapes of a vibrating structure, from acoustic measurements of the generated sound field. The software consists in Matlab source code, and automatically downloads the needed database. It allows to reproduce all results and figures of the paper, and to experiment some additional settings. It is distributed under GPL 3.0 license.
